Detailed Description

KMainWindow represents a top-level main window.

It extends QMainWindow with session management capabilities. For ready-made window functionality and simpler UI management, use KXmlGuiWindow instead.

Define the minimum/maximum height/width of your central widget and KMainWindow will take this into account. For fixed size windows set your main widget to a fixed size. Fixed aspect ratios (QWidget::heightForWidth()) and fixed width widgets are not supported.

Use toolBar() to generate a main toolbar "mainToolBar" or refer to a specific toolbar. For a simpler way to manage your toolbars, use KXmlGuiWindow::setupGUI() instead.

Use setAutoSaveSettings() to automatically save and restore the window geometry and toolbar/menubar/statusbar state when the application is restarted.

Use kRestoreMainWindows() in your main function to restore your windows when the session is restored.

The window state is saved when the application is exited. Reimplement queryClose() to warn the user of unsaved data upon close or exit.

Reimplement saveProperties() / readProperties() or saveGlobalProperties() / readGlobalProperties() to save/restore application-specific state during session management.

Note that session saving is automatically called, session restoring is not, and so it needs to be implemented in your main() function.

See https://develop.kde.org/docs/use/session-managment for more information on session management.

Constructor & Destructor Documentation

◆ KMainWindow() [1/2]

KMainWindow::KMainWindow	(	QWidget *	parent = nullptr,
		Qt::WindowFlags	flags = Qt::WindowFlags() )

explicit

Constructs a main window.

Parameters

parent	The parent widget. This is usually `nullptr`, but it may also be the window group leader. In that case, the KMainWindow becomes a secondary window.
flags	Specify the window flags. The default is none.

Note that by default a KMainWindow is created with the Qt::WA_DeleteOnClose attribute set, i.e. it is automatically destroyed when the window is closed. If you do not want this behavior, call

window->setAttribute(Qt::WA_DeleteOnClose, false);

KMainWindows must be created on the heap with 'new', like:

KMainWindow *kmw = new KMainWindow(...);

kmw->setObjectName(...);

Since KDE Frameworks 5.16, KMainWindow will enter information regarding the application's translators by default, using KAboutData::setTranslator(). This only occurs if no translators are already assigned in KAboutData (see KAboutData::setTranslator() for details – the auto-assignment here uses the same translated strings as specified for that function).

IMPORTANT: For session management and window management to work properly, all main windows in the application should have a different name. Otherwise, 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 replace it with 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#".

Member Function Documentation

◆ appHelpActivated

void KMainWindow::appHelpActivated ( )

slot

Opens 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):

toolBar()->addAction(QIcon::fromTheme("help-contents"), i18n("Help"),

this, &KMainWindow::appHelpActivated);

KMainWindow::appHelpActivated

void appHelpActivated()

Opens the help page for the application.

Parameters

config Config group to read the settings from.

Reimplemented in KXmlGuiWindow.

Definition at line 675 of file kmainwindow.cpp.

◆ autoSaveConfigGroup()

KConfigGroup KMainWindow::autoSaveConfigGroup ( ) const

Returns: The group used for autosaving settings.

Only meaningful if setAutoSaveSettings(const QString&, bool) was called.

Do not use this method if setAutoSaveSettings(const KConfigGroup&, bool) was called.

This can be useful for forcing an apply, e.g. after using KEditToolBar.

Returns: The class name of the top-level window to be restored that corresponds to instanceNumber.

Parameters

instanceNumber

See also: restore()

Definition at line 449 of file kmainwindow.cpp.

◆ closeEvent()

void KMainWindow::closeEvent ( QCloseEvent * e )

overrideprotectedvirtual

Reimplemented to autosave settings and call queryClose().

We recommend that you reimplement queryClose() rather than closeEvent(). If you do it anyway, ensure to call the base implementation to keep the feature of autosaving window settings working.

Reimplemented from QWidget.

Definition at line 511 of file kmainwindow.cpp.

◆ dbusName()

QString KMainWindow::dbusName ( ) const

Returns: The path for the exported window's D-Bus object.

Since: 4.0.1

◆ event()

bool KMainWindow::event ( QEvent * event )

overrideprotectedvirtual

Reimplemented to catch QEvent::Polish in order to adjust the object name if needed, once all constructor code for the main window has run.

Also reimplemented to catch when a QDockWidget is added or removed.

Reimplemented from QMainWindow.

Reimplemented in KXmlGuiWindow.

Definition at line 851 of file kmainwindow.cpp.

◆ hasMenuBar()

bool KMainWindow::hasMenuBar ( )

Returns: true if there is a menubar, false otherwise.

◆ keyPressEvent()

Reimplemented from QWidget.

Definition at line 909 of file kmainwindow.cpp.

◆ memberList()

QList< KMainWindow * > KMainWindow::memberList ( )

static

Returns: The list of members of the KMainWindow class.

Definition at line 988 of file kmainwindow.cpp.

◆ queryClose()

bool KMainWindow::queryClose ( )

protectedvirtual

This function is called before the window is closed, either by the user or indirectly by the session manager.

This can be used to prompt the user to save unsaved data before the window is closed.

Example:

switch ( KMessageBox::warningTwoActionsCancel( this,
         i18n("Save changes to document foo?"), QString(),
         KStandardGuiItem::save(), KStandardGuiItem::discard())) ) {
  case KMessageBox::PrimaryAction :
    // save document here. If saving fails, return false;
    return true;
  case KMessageBox::SecondaryAction :
    return true;
  default: // cancel
    return false;

Note: Do not 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.

Returns: true by default, false according to the reimplementation. Returning false will cancel the closing operation, and if KApplication::sessionSaving() is true, it cancels logout.

Definition at line 553 of file kmainwindow.cpp.

◆ readGlobalProperties()

void KMainWindow::readGlobalProperties ( KConfig * sessionConfig )

protectedvirtual

Reads your application-wide properties.

Parameters

sessionConfig A pointer to the KConfig instance used to load the session data.

See also: saveGlobalProperties(); readProperties()

Definition at line 562 of file kmainwindow.cpp.

◆ readProperties()

virtual void KMainWindow::readProperties ( const KConfigGroup & )

inlineprotectedvirtual

Reads your instance-specific properties.

This function is called indirectly by restore().

void MainWindow::readProperties(KConfigGroup &config) {
  if (config.hasKey("myKey")) {
    config.readEntry("myKey", "DefaultValue");
  }
  ...
}

See also: readGlobalProperties()

Definition at line 560 of file kmainwindow.h.

◆ readPropertiesInternal()

bool KMainWindow::readPropertiesInternal	(	KConfig *	config,
		int	number )

protected

Definition at line 644 of file kmainwindow.cpp.

◆ resetAutoSaveSettings()

void KMainWindow::resetAutoSaveSettings ( )

Disables the autosave settings feature.

You don't normally need to call this, ever.

See also: setAutoSaveSettings(); autoSaveSettings()

Definition at line 801 of file kmainwindow.cpp.

◆ restore()

bool KMainWindow::restore	(	int	numberOfInstances,
		bool	show = true )

Attempt to restore the top-level widget as defined by numberOfInstances (1..X).

You should call canBeRestored() first.

If the session did not contain so high a number, the configuration is not changed and false is returned.

That means clients could simply do the following:

if (qApp->isSessionRestored()){
  int n = 1;
  while (KMainWindow::canBeRestored(n)){
    (new childMW)->restore(n);
    n++;
  }
} else {
  // create default application as usual
}

Note that if show is true (default), QWidget::show() is called implicitly in restore.

With this you can easily restore all top-level windows of your application.

If your application uses different kinds of top-level windows, then you can use KMainWindow::classNameOfToplevel(n) to determine the exact type before calling the childMW constructor in the example from above.

Note: You don't need to deal with this function. Use the kRestoreMainWindows() convenience template function instead!

Parameters

numberOfInstances	The number of KMainWindow instances from the last session.
show	Whether the KMainWindow instances will be visible by default.

Returns: true if the session contained the same number of instances as the requested number, false if the session contained less instances than the requested number, in which case no configuration is changed.

See also: kRestoreMainWindows(); readProperties(); canBeRestored()

Definition at line 464 of file kmainwindow.cpp.

◆ saveAutoSaveSettings

void KMainWindow::saveAutoSaveSettings ( )

protectedslot

This slot should only be called in case you reimplement closeEvent() and if you are using the autosave feature.

In all other cases, setSettingsDirty() should be called instead to benefit from the delayed saving.

Example:

void MyMainWindow::closeEvent( QCloseEvent *e )
{
  // Save settings if autosave is enabled, and settings have changed
  if ( settingsDirty() && autoSaveSettings() )
    saveAutoSaveSettings();
  ..
}

See also: setAutoSaveSettings(); setSettingsDirty()

Definition at line 840 of file kmainwindow.cpp.

◆ saveGlobalProperties()

void KMainWindow::saveGlobalProperties ( KConfig * sessionConfig )

protectedvirtual

Saves your application-wide properties.

Parameters

sessionConfig A pointer to the KConfig instance used to save the session data.

This function is invoked when the session manager requests your application to save its state. It is similar to saveProperties(), but it is only called for the first main window. This is useful to save global state of your application that isn't bound to a particular window.

The default implementation does nothing.

See also: readGlobalProperties(); saveProperties()

Definition at line 558 of file kmainwindow.cpp.

◆ saveMainWindowSettings()

void KMainWindow::saveMainWindowSettings ( KConfigGroup & config )

Manually save the settings for statusbar, menubar and toolbar to their respective groups in the KConfigGroup config.

Example:

KConfigGroup group(KSharedConfig::openConfig(), "MainWindow");

saveMainWindowSettings(group);

KMainWindow::saveMainWindowSettings

void saveMainWindowSettings(KConfigGroup &config)

Definition kmainwindow.cpp:587

KSharedConfig::openConfig

static KSharedConfig::Ptr openConfig(const QString &fileName=QString(), OpenFlags mode=FullConfig, QStandardPaths::StandardLocation type=QStandardPaths::GenericConfigLocation)

Parameters

config Config group to save the settings to.

See also: setAutoSaveSettings(); KConfig; KSharedConfig; KConfigGroup

Definition at line 587 of file kmainwindow.cpp.

◆ saveProperties()

virtual void KMainWindow::saveProperties ( KConfigGroup & )

inlineprotectedvirtual

Saves your instance-specific properties.

The function is invoked when the session manager requests your application to save its state.

Reimplement this function in child classes.

void MainWindow::saveProperties(KConfigGroup &config) {
  config.writeEntry("myKey", "newValue");
  ...
}

Note: No user interaction is allowed in this function!

Definition at line 540 of file kmainwindow.h.

◆ savePropertiesInternal()

void KMainWindow::savePropertiesInternal	(	KConfig *	config,
		int	number )

protected

Definition at line 566 of file kmainwindow.cpp.

◆ setAutoSaveSettings() [1/2]

void KMainWindow::setAutoSaveSettings	(	const KConfigGroup &	group,
		bool	saveWindowSize = true )

This is an overloaded function.

This allows the settings to be saved into a different file that does not correspond to that used for KSharedConfig::openConfig().

See also: setAutoSaveSettings(const QString &groupName, bool saveWindowSize); KConfig; KSharedConfig

Since: 4.1

Definition at line 782 of file kmainwindow.cpp.

◆ setAutoSaveSettings() [2/2]

void KMainWindow::setAutoSaveSettings	(	const QString &	groupName = QStringLiteral("MainWindow"),
		bool	saveWindowSize = true )

This enables autosave of toolbar/menubar/statusbar settings (and optionally window size).

Parameters

groupName	A name that identifies the type of window. You can have several types of window in the same application. If no `groupName` is specified, the value defaults to "MainWindow".
saveWindowSize	Whether to include the window size when saving. `true` by default.

If the *bars were modified when the window is closed, saveMainWindowSettings( KConfigGroup(KSharedConfig::openConfig(), groupName) ) will be called.

Typically, you will call setAutoSaveSettings() in your KMainWindow-inherited class constructor, and it will take care of restoring and saving automatically.

By default, this generates an appnamerc ini file as if using default KConfig constructor or KConfig::SimpleConfig.

Make sure you call this after all your *bars have been created.

To make sure that KMainWindow properly obtains the default size of the window you should do the following:

Remove hardcoded resize() calls in the constructor or main to let the automatic resizing determine the default window size. Hardcoded 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() call after all widgets have been created and placed inside the main window (for most apps this means QMainWindow::setCentralWidget())
QWidget-based objects should overload "virtual QSize sizeHint() const;" to specify a default size.

◆ setCaption [1/2]

void KMainWindow::setCaption ( const QString & caption )

virtualslot

Assigns a KDE compliant caption (window title).

Parameters

caption The string that will be displayed in the window title, before the application name.

Note: This function does the same as setPlainCaption().; Do not include the application name in this string. It will be added automatically according to the KDE standard.

See also: setPlainCaption()

Definition at line 479 of file kmainwindow.cpp.

◆ setCaption [2/2]

void KMainWindow::setCaption	(	const QString &	caption,
		bool	modified )

virtualslot

Makes a KDE compliant caption.

Parameters

caption	Your caption.
modified	Whether the document is modified. This displays an additional sign in the title bar, usually "**".

This is an overloaded function.

Note: Do not include the application name in this string. It will be added automatically according to the KDE standard.

Definition at line 484 of file kmainwindow.cpp.

◆ setPlainCaption

void KMainWindow::setPlainCaption ( const QString & caption )

virtualslot

Make a plain caption without any modifications.

Parameters

caption The string that will be displayed in the window title, before the application name.

Note: This function does the same as setCaption().; Do not include the application name in this string. It will be added automatically according to the KDE standard.

See also: setCaption()

Definition at line 494 of file kmainwindow.cpp.

◆ setSettingsDirty

void KMainWindow::setSettingsDirty ( )

slot

Tell the main window that it should save its settings when being closed.

This is part of the autosave 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.

See also: saveAutoSaveSettings()

Definition at line 765 of file kmainwindow.cpp.

◆ setStateConfigGroup()

void KMainWindow::setStateConfigGroup ( const QString & configGroup )

Assigns the config group name for the KConfigGroup returned by stateConfigGroup.

Parameters

configGroup The config group to be assigned. Window size and state are stored in the resulting KConfigGroup when this function is called.

Note: If this is used in combination with setAutoSaveSettings, you should call this method first.

See also: KConfigGroup(); KSharedConfig::openStateConfig(); stateConfigGroup()

Since: 5.88

Definition at line 828 of file kmainwindow.cpp.

◆ settingsDirty()

bool KMainWindow::settingsDirty ( ) const

protected

For inherited classes.

Definition at line 771 of file kmainwindow.cpp.

◆ stateConfigGroup()

KConfigGroup KMainWindow::stateConfigGroup ( ) const

Returns: The KConfigGroup used to store state data like window sizes or window state.

The resulting group is invalid if setStateConfig is not called explicitly.

See also: KConfigGroup

Since: 5.88

Definition at line 834 of file kmainwindow.cpp.

◆ toolBar()

KToolBar * KMainWindow::toolBar ( const QString & name = QString() )

This is useful to both call specific toolbars that have been created or to generate a default one upon call.

This refers to toolbars created dynamically from the XML UI framework via KConfig or appnameui.rc.

If the toolbar does not exist, one will be created.

Parameters

name	The internal name of the toolbar. If no name is specified, "mainToolBar" is assumed.

Returns: A pointer to the toolbar with the specified name.

See also: toolBars()

Definition at line 958 of file kmainwindow.cpp.

◆ toolBars()

QList< KToolBar * > KMainWindow::toolBars ( ) const

Returns: A list of all toolbars for this window
