Detailed Description
KDE top level main windowTop level widget that provides toolbars, a status line and a frame.
It should be used as a top level (parent-less) widget. It manages the geometry for all its children, including your main widget.
Normally, you will inherit from KMainWindow, then construct (or use some existing) widget as your main view. You can set only one main view.
You can add as many toolbars as you like. There can be only one menubar and only one statusbar.
The toolbars, menubar, and statusbar can be created by the KMainWindow and - unlike the old KMainWindow - may, but do not have to, be deleted by you. KMainWindow will handle that internally.
Height and width can be operated independently from each other. Simply define the minimum/maximum height/width of your main widget and KMainWindow will take this into account. For fixed size windows set your main widget to a fixed size.
Fixed aspect ratios (heightForWidth()) and fixed width widgets are not supported.
KMainWindow will set icon, mini icon and caption, which it gets from KApplication. It provides full session management, and will save its position, geometry and positions of toolbars and menubar on logout. If you want to save additional data, reimplement saveProperties() and (to read them again on next login) readProperties(). To save special data about your data, reimplement saveGlobalProperties(). To warn user that application or windows have unsaved data on close or logout, reimplement queryClose() and/or queryExit().
There are also kRestoreMainWindows convenience functions which can restore all your windows on next login.
Note that a KMainWindow per-default is created with the WDestructiveClose flag, i.e. it is automatically destroyed when the window is closed. If you do not want this behavior, specify 0 as widget flag in the constructor.

- KApplication
Definition at line 98 of file kmainwindow.h.
Member Enumeration Documentation
Flags that can be passed in an argument to the constructor to change the behavior.
NoDCOPObject tells KMainWindow not to create a KMainWindowInterface. This can be useful in particular for inherited classes, which might want to create more specific dcop interfaces. It's a good idea to use KMainWindowInterface as the base class for such interfaces though (to provide the standard mainwindow functionality via DCOP).

- setupGUI()
- Enumerator:

ToolBar adds action to show/hide the toolbar(s) and adds action to configure the toolbar(s). - See also:
- setStandardToolBarMenuEnabled
Keys adds action to show the key configure action. StatusBar adds action to show/hide the statusbar if the statusbar exists. See createStandardStatusBarAction
Save auto-saves (and loads) the toolbar/menubar/statusbar settings and window size using the default name. See setAutoSaveSettings
Typically you want to let the default window size be determined by the widgets size hints. Make sure that setupGUI() is called after all the widgets are created ( including setCentralWidget ) so the default size's will be correct. See setAutoSaveSettings for more information on this topic.
Create calls createGUI() once ToolBar, Keys and Statusbar have been taken care of. See createGUI

Constructor & Destructor Documentation
KMainWindow::KMainWindow | ( | QWidget * | parent = 0 , |
|
const char * | name = 0 , |
|||
WFlags | f = WType_TopLevel | WDestructiveClose | |||
) |
Construct a main window.
- Parameters:
-
parent The widget parent. This is usually 0 but it may also be the window group leader. In that case, the KMainWindow becomes sort of a secondary window. name The object name. For session management and window management to work properly, all main windows in the application should have a different name. When passing 0 (the default), KMainWindow will create a unique name, but it's recommended to explicitly pass a window name that will also describe the type of the window. If there can be several windows of the same type, append '#' (hash) to the name, and KMainWindow will append numbers to make the names unique. For example, for a mail client which has one main window showing the mails and folders, and which can also have one or more windows for composing mails, the name for the folders window should be e.g. "mainwindow" and for the composer windows "composer#". f Specify the widget flags. The default is WType_TopLevel and WDestructiveClose. TopLevel indicates that a main window is a toplevel window, regardless of whether it has a parent or not. DestructiveClose indicates that a main window is automatically destroyed when its window is closed. Pass 0 if you do not want this behavior.
KMainWindow *kmw = new KMainWindow (...);

KMainWindow::KMainWindow | ( | int | cflags, | |
QWidget * | parent = 0 , |
|||
const char * | name = 0 , |
|||
WFlags | f = WType_TopLevel | WDestructiveClose | |||
) |
Overloaded constructor which allows passing some KMainWindow::CreationFlags.
- Since:
- 3.2
Definition at line 173 of file kmainwindow.cpp.
KMainWindow::~KMainWindow | ( | ) | [virtual] |
Destructor.
Will also destroy the toolbars, and menubar if needed.
Definition at line 314 of file kmainwindow.cpp.
Member Function Documentation
KAccel * KMainWindow::accel | ( | ) |
- Returns:
- A KAccel instance bound to this mainwindow. Used automatically by KAction to make keybindings work in all cases.
Definition at line 1171 of file kmainwindow.cpp.
void KMainWindow::appHelpActivated | ( | void | ) | [slot] |
Open the help page for the application.
The application name is used as a key to determine what to display and the system will attempt to open <appName>/index.html.
This method is intended for use by a help button in the toolbar or components outside the regular help menu. Use helpMenu() when you want to provide access to the help system from the help menu.
Example (adding a help button to the first toolbar):
KIconLoader &loader = *KGlobal::iconLoader(); QPixmap pixmap = loader.loadIcon( "help" ); toolBar(0)->insertButton( pixmap, 0, SIGNAL(clicked()), this, SLOT(appHelpActivated()), true, i18n("Help") );

void KMainWindow::applyMainWindowSettings | ( | KConfig * | config, | |
const QString & | groupName = QString::null | |||
) |
Definition at line 829 of file kmainwindow.cpp.
void KMainWindow::applyMainWindowSettings | ( | KConfig * | config, | |
const QString & | groupName, | |||
bool | force | |||
) |
Read settings for statusbar, menubar and toolbar from their respective groups in the config file and apply them.
- Parameters:
-
config Config file to read the settings from. groupName Group name to use. If not specified, the last used group name is used. force if set, even default settings are re-applied
Definition at line 834 of file kmainwindow.cpp.
QString KMainWindow::autoSaveGroup | ( | ) | const |
- Returns:
- the group used for setting-autosaving. Only meaningful if setAutoSaveSettings() was called. This can be useful for forcing a save or an apply, e.g. before and after using KEditToolbar.
- Since:
- 3.1
Definition at line 1044 of file kmainwindow.cpp.
bool KMainWindow::autoSaveSettings | ( | ) | const |
- Returns:
- the current autosave setting, i.e. true if setAutoSaveSettings() was called, false by default or if resetAutoSaveSettings() was called.
- Since:
- 3.1
Definition at line 1039 of file kmainwindow.cpp.
bool KMainWindow::canBeRestored | ( | int | number | ) | [static] |
Session Management
Try to restore the toplevel widget as defined by the number (1..X).
If the session did not contain so high a number, the configuration is not changed and false
returned.
That means clients could simply do the following:
if (kapp->isRestored()){ int n = 1; while (KMainWindow::canBeRestored(n)){ (new childMW)->restore(n); n++; } } else { // create default application as usual }
With this you can easily restore all toplevel windows of your application.
If your application uses different kinds of toplevel windows, then you can use KMainWindow::classNameOfToplevel(n) to determine the exact type before calling the childMW constructor in the example from above.
If your client has only one kind of toplevel widgets (which should be pretty usual) then you should use the RESTORE-macro for backwards compatibility with 3.1 and 3.0 branches:
if (kapp->isRestored()) RESTORE(childMW) else { // create default application as usual }
The macro expands to the term above but is easier to use and less code to write.
For new code or if you have more than one kind of toplevel widget (each derived from KMainWindow, of course), you can use the templated kRestoreMainWindows global functions:
if (kapp->isRestored()) kRestoreMainWindows< childMW1, childMW2, childMW3 >(); else { // create default application as usual }
Currently, these functions are provided for up to three template arguments. If you need more, tell us. To help you in deciding whether or not you can use kRestoreMainWindows, a define KDE_RESTORE_MAIN_WINDOWS_NUM_TEMPLATE_ARGS is provided.
- See also:
- restore()
Definition at line 352 of file kmainwindow.cpp.
void KMainWindow::childEvent | ( | QChildEvent * | e | ) | [protected] |
const QString KMainWindow::classNameOfToplevel | ( | int | number | ) | [static] |
Returns the className() of the number
of the toplevel window which should be restored.
This is only useful if your application uses different kinds of toplevel windows.
Definition at line 364 of file kmainwindow.cpp.
void KMainWindow::closeEvent | ( | QCloseEvent * | e | ) | [protected, virtual] |
Reimplemented to call the queryClose() and queryExit() handlers.
We recommend that you reimplement the handlers rather than closeEvent(). If you do it anyway, ensure to call the base implementation to keep queryExit() running.
Definition at line 634 of file kmainwindow.cpp.
int KMainWindow::configureToolbars | ( | ) | [slot] |
Show a standard configure toolbar dialog.
This slot can be connected dirrectly to the action to configure shortcuts. This is very simple to do that by adding a single line
KStdAction::configureToolbars( guiFactory(), SLOT( configureToolbars() ), actionCollection() );
- Since:
- 3.3
Definition at line 431 of file kmainwindow.cpp.
void KMainWindow::createGUI | ( | const QString & | xmlfile = QString::null , |
|
bool | _conserveMemory = true | |||
) |
Create a GUI given a local XML file.
If xmlfile
is NULL, then it will try to construct a local XML filename like appnameui.rc where 'appname' is your app's name. If that file does not exist, then the XML UI code will only use the global (standard) XML file for the layout purposes.
Note that when passing true for the conserveMemory argument subsequent calls to guiFactory()->addClient/removeClient may not work as expected. Also retrieving references to containers like popup menus or toolbars using the container method will not work.
- Parameters:
-
xmlfile The local xmlfile (relative or absolute) _conserveMemory Specify whether createGUI() should call KXMLGUIClient::conserveMemory() to free all memory allocated by the QDomDocument and by the KXMLGUIFactory.
Definition at line 491 of file kmainwindow.cpp.
void KMainWindow::createStandardStatusBarAction | ( | ) |
Sets whether KMainWindow should provide a menu that allows showing/hiding of the statusbar ( using KToggleStatusBarAction ).
The menu / menu item is implemented using xmlgui. It will be inserted in your menu structure in the 'Settings' menu.
Note that you should enable this feature before calling createGUI() ( or similar ).
If an application maintains the action on its own (i.e. never calls this function) a connection needs to be made to let KMainWindow know when that status (hidden/shown) of the statusbar has changed. For example: connect(action, SIGNAL(activated()), kmainwindow, SLOT(setSettingsDirty())); Otherwise the status (hidden/show) of the statusbar might not be saved by KMainWindow.
- Since:
- 3.2
Definition at line 796 of file kmainwindow.cpp.
KPopupMenu * KMainWindow::customHelpMenu | ( | bool | showWhatsThis = true |
) |
Returns the help menu.
Creates a standard help menu if none exists yet.
It contains entries for the help system (activated by F1), an optional "What's This?" entry (activated by Shift F1), an application specific dialog box, and an "About KDE" dialog box. You must create the application specific dialog box yourself. When the "About application" menu entry is activated, a signal will trigger the showAboutApplication slot. See showAboutApplication for more information.
Example (adding a help menu to your application):
menuBar()->insertItem( i18n("&Help"), customHelpMenu() );
- Parameters:
-
showWhatsThis Set this to false
if you do not want to include the "What's This" menu entry.
- Returns:
- A standard help menu.

bool KMainWindow::hasMenuBar | ( | ) |
KPopupMenu * KMainWindow::helpMenu | ( | const QString & | aboutAppText = QString::null , |
|
bool | showWhatsThis = true | |||
) |
Retrieve the standard help menu.
It contains entires for the help system (activated by F1), an optional "What's This?" entry (activated by Shift F1), an application specific dialog box, and an "About KDE" dialog box.
Example (adding a standard help menu to your application):
KPopupMenu *help = helpMenu( <myTextString> ); menuBar()->insertItem( i18n("&Help"), help );
- Parameters:
-
aboutAppText The string that is used in the application specific dialog box. If you leave this string empty the information in the global KAboutData of the application will be used to make a standard dialog box. showWhatsThis Set this to false if you do not want to include the "What's This" menu entry.
- Returns:
- A standard help menu.
Definition at line 324 of file kmainwindow.cpp.
void KMainWindow::hide | ( | ) | [virtual] |
void KMainWindow::ignoreInitialGeometry | ( | ) |
For internal use only.
Used from Konqueror when reusing the main window.
Definition at line 985 of file kmainwindow.cpp.
bool KMainWindow::initialGeometrySet | ( | ) | const |
- Returns:
- true if a -geometry argument was given on the command line, and this is the first window created (the one on which this option applies)
Definition at line 980 of file kmainwindow.cpp.
bool KMainWindow::isHelpMenuEnabled | ( | ) |
bool KMainWindow::isStandardToolBarMenuEnabled | ( | ) | const |
KMenuBar * KMainWindow::menuBar | ( | ) |
Returns a pointer to the menu bar.
If there is no menu bar yet one will be created.
Definition at line 1071 of file kmainwindow.cpp.
void KMainWindow::paintEvent | ( | QPaintEvent * | e | ) | [protected] |
Definition at line 1178 of file kmainwindow.cpp.
void KMainWindow::parseGeometry | ( | bool | parsewidth | ) | [protected] |
parse the geometry from the geometry command line argument
Definition at line 279 of file kmainwindow.cpp.
bool KMainWindow::queryClose | ( | ) | [protected, virtual] |
Called before the window is closed, either by the user or indirectly by the session manager.
The purpose of this function is to prepare the window in a way that it is safe to close it, i.e. without the user losing some data.
Default implementation returns true. Returning false
will cancel the closing, and, if KApplication::sessionSaving() is true, it will also cancel KDE logout.
Reimplement this function to prevent the user from losing data. Example:
switch ( KMessageBox::warningYesNoCancel( this, i18n("Save changes to document foo?")) ) { case KMessageBox::Yes : save document here. If saving fails, return false; return true; case KMessageBox::No : return true; default: // cancel return false;
Note that you should probably not actually close the document from within this method, as it may be called by the session manager before the session is saved. If the document is closed before the session save occurs, its location might not be properly saved. In addition, the session shutdown may be canceled, in which case the document should remain open.
- See also:
- queryExit()
KApplication::sessionSaving()
Definition at line 669 of file kmainwindow.cpp.
bool KMainWindow::queryExit | ( | ) | [protected, virtual] |
Called before the very last window is closed, either by the user or indirectly by the session manager.
It is not recommended to do any user interaction in this function other than indicating severe errors. Better ask the user on queryClose() (see below).
A typical usage of queryExit() is to write configuration data back. Note that the application may continue to run after queryExit() (the user may have canceled a shutdown), so you should not do any cleanups here. The purpose of queryExit() is purely to prepare the application (with possible user interaction) so it can safely be closed later (without user interaction).
If you need to do serious things on exit (like shutting a dial-up connection down), connect to the signal KApplication::shutDown().
Default implementation returns true
. Returning false
will cancel the exiting. In the latter case, the last window will remain visible. If KApplication::sessionSaving() is true, refusing the exit will also cancel KDE logout.

bool KMainWindow::restore | ( | int | number, | |
bool | show = true | |||
) |
Restore the session specified by number
.
Returns false
if this fails, otherwise returns true
and shows the window. You should call canBeRestored() first. If show
is true (default), this widget will be shown automatically.
Definition at line 411 of file kmainwindow.cpp.
void KMainWindow::restoreWindowSize | ( | KConfig * | config | ) | [protected] |
For inherited classes Note that the group must be set before calling, and that a -geometry on the command line has priority.
Definition at line 934 of file kmainwindow.cpp.
void KMainWindow::saveAutoSaveSettings | ( | ) | [protected, slot] |
This slot should only be called in case you reimplement closeEvent() and if you are using the "auto-save" feature.
In all other cases, setSettingsDirty() should be called instead to benefit from the delayed saving.
- See also:
- setAutoSaveSettings
- Since:
- 3.2
void MyMainWindow::closeEvent( QCloseEvent *e ) { // Save settings if auto-save is enabled, and settings have changed if ( settingsDirty() && autoSaveSettings() ) saveAutoSaveSettings(); .. }
Definition at line 1049 of file kmainwindow.cpp.
void KMainWindow::saveGlobalProperties | ( | KConfig * | sessionConfig | ) | [protected, virtual] |
Save your application-wide properties.
The function is invoked when the session manager requests your application to save its state.
This function is similar to saveProperties() but is only called for the very first main window, regardless how many main window are open.
Override it if you need to save other data about your documents on session end. sessionConfig is a config to which that data should be saved. Normally, you don't need this function. But if you want to save data about your documents that are not in opened windows you might need it.
Default implementation does nothing.
Definition at line 674 of file kmainwindow.cpp.
void KMainWindow::saveMainWindowSettings | ( | KConfig * | config, | |
const QString & | groupName = QString::null | |||
) |
Save settings for statusbar, menubar and toolbar to their respective groups in the config file config
.
- Parameters:
-
config Config file to save the settings to. groupName Group name to use. If not specified, the last used group name is used
Definition at line 716 of file kmainwindow.cpp.
void KMainWindow::saveNewToolbarConfig | ( | ) | [protected, slot] |
Rebuilds the GUI after KEditToolbar changed the toolbar layout.
- See also:
- configureToolbars()
Definition at line 439 of file kmainwindow.cpp.
virtual void KMainWindow::saveProperties | ( | KConfig * | ) | [inline, protected, virtual] |
Save your instance-specific properties.
The function is invoked when the session manager requests your application to save its state.
You must not change the group of the kconfig
object, since KMainWindow uses one group for each window. Please reimplement these function in childclasses.
Note: No user interaction is allowed in this function!

For inherited classes Note that the group must be set before calling.
Definition at line 902 of file kmainwindow.cpp.
void KMainWindow::setAutoSaveSettings | ( | const QString & | groupName = QString::fromLatin1("MainWindow") , |
|
bool | saveWindowSize = true | |||
) |
Call this to enable "auto-save" of toolbar/menubar/statusbar settings (and optionally window size).
If the *bars were moved around/shown/hidden when the window is closed, saveMainWindowSettings( KGlobal::config(), groupName ) will be called.
- Parameters:
-
groupName a name that identifies this "type of window". You can have several types of window in the same application. saveWindowSize set it to true to include the window size when saving.
To make sure that KMainWindow propertly obtains the default size of the window you should do the following:
- Remove hard coded resize() calls in the constructor or main, they should be removed in favor of letting the automatic resizing determine the default window size. Hard coded window sizes will be wrong for users that have big fonts, use different styles, long/small translations, large toolbars, and other factors.
- Put the setAutoSaveSettings ( or setupGUI() ) call after all widgets have been created and placed inside the main window (i.e. for 99% of apps setCentralWidget())
- Widgets that inherit from QWidget (like game boards) should overload "virtual QSize sizeHint() const;" to specify a default size rather than letting QWidget::adjust use the default size of 0x0.
Definition at line 1017 of file kmainwindow.cpp.
void KMainWindow::setCaption | ( | const QString & | caption, | |
bool | modified | |||
) | [virtual, slot] |
Makes a KDE compliant caption.
- Parameters:
-
caption Your caption. Do not include the application name in this string. It will be added automatically according to the KDE standard. modified Specify whether the document is modified. This displays an additional sign in the title bar, usually "**".
Definition at line 586 of file kmainwindow.cpp.
void KMainWindow::setCaption | ( | const QString & | caption | ) | [virtual, slot] |
Makes a KDE compliant caption.
- Parameters:
-
caption Your caption. Do not include the application name in this string. It will be added automatically according to the KDE standard.

void KMainWindow::setHelpMenuEnabled | ( | bool | showHelpMenu = true |
) |
Enables the build of a standard help menu when calling createGUI().
The default behavior is to build one, you must call this function to disable it
Definition at line 571 of file kmainwindow.cpp.
void KMainWindow::setIcon | ( | const QPixmap & | p | ) | [virtual] |
void KMainWindow::setPlainCaption | ( | const QString & | caption | ) | [virtual, slot] |
Make a plain caption without any modifications.
- Parameters:
-
caption Your caption. This is the string that will be displayed in the window title.
Definition at line 591 of file kmainwindow.cpp.
void KMainWindow::setSettingsDirty | ( | ) | [slot] |
Apply a state change.
Enable and disable actions as defined in the XML rc file, can "reverse" the state (disable the actions which should be enabled, and vice-versa) if specified. Tell the main window that it should save its settings when being closed. This is part of the auto-save-settings feature. For everything related to toolbars this happens automatically, but you have to call setSettingsDirty() in the slot that toggles the visibility of the statusbar.
Definition at line 990 of file kmainwindow.cpp.
void KMainWindow::setStandardToolBarMenuEnabled | ( | bool | enable | ) |
Sets whether KMainWindow should provide a menu that allows showing/hiding the available toolbars ( using KToggleToolBarAction ) .
In case there is only one toolbar configured a simple 'Show <toolbar name here>' menu item is shown.
The menu / menu item is implemented using xmlgui. It will be inserted in your menu structure in the 'Settings' menu.
If your application uses a non-standard xmlgui resource file then you can specify the exact position of the menu / menu item by adding a <Merge name="StandardToolBarMenuHandler" /> line to the settings menu section of your resource file ( usually appname.rc ).
Note that you should enable this feature before calling createGUI() ( or similar ) . You enable/disable it anytime if you pass false to the conserveMemory argument of createGUI.

void KMainWindow::setupToolbarMenuActions | ( | ) |
void KMainWindow::show | ( | void | ) | [virtual] |
void KMainWindow::showAboutApplication | ( | ) | [protected, virtual, slot] |
This slot does nothing.
It must be reimplemented if you want to use a custom About Application dialog box. This slot is connected to the About Application entry in the menu returned by customHelpMenu.
Example:
void MyMainLevel::setupInterface() { .. menuBar()->insertItem( i18n("&Help"), customHelpMenu() ); .. } void MyMainLevel::showAboutApplication() { <activate your custom dialog> }

- Returns:
- the size the mainwindow should have so that the central widget will be of
size
.
- Deprecated:
- You normally don't need this, the recommended way to achieve a certain central widget size is as follows:
- Override sizeHint() in the central widget so that it returns the desired size.
- Call updateGeometry() in the central widget whenever the desired size changes. This ensures that the new sizeHint() is properly propagated to any parent layout.
- Now call adjustSize() in the mainwindow to resize the mainwindow such that the central widget will become the desired size.
