- Returns:
- true if default background images may be used
| appearanceChanged | ( | self ) |
Emitted when the application has changed either its GUI style, its font or its palette in response to a kdisplay request. Normally, widgets will update their styles automatically, but you should connect to this to program special behavior.

QObject.connect(source, SIGNAL("appearanceChanged()"), target_slot)
| int autoSelectDelay | ( | ) |
Returns the KDE setting for the auto-select option.
- Returns:

- Completion. Default is CompletionPopup.
| int contextMenuKey | ( | ) |
Returns the KDE setting for the shortcut key to open context menus.

| int contrast | ( | ) |
Returns the contrast for borders.
- Returns:
- the contrast (between 0 for minimum and 10 for maximum contrast)
| float contrastF | ( | KSharedConfigPtr | config=KSharedConfigPtr() | |
| ) |
Returns the contrast for borders as a floating point value.
- Parameters:
-
config pointer to the config from which to read the contrast setting (the default is to use KGlobal.config())
- Returns:
- the contrast (between 0.0 for minimum and 1.0 for maximum contrast)
| QPalette createApplicationPalette | ( | KSharedConfigPtr | config=KSharedConfigPtr() | |
| ) |
Used to obtain the QPalette that will be used to set the application palette.
This is only useful for configuration modules such as krdb and should not be used in normal circumstances.
- Parameters:
-
config KConfig from which to load the colors (passed as-is to .KColorScheme).
- Returns:
- the QPalette
| cursorChanged | ( | self ) |
Emitted when the cursor theme has been changed.
- Signal syntax:
QObject.connect(source, SIGNAL("cursorChanged()"), target_slot)
This function returns the desktop geometry for an application that needs to set the geometry of a widget on the screen manually. It takes into account the user's display settings (number of screens, Xinerama, etc), and the user's preferences (if KDE should be Xinerama aware).
Note that this can break in multi-head (not Xinerama) mode because this point could be on multiple screens. Use with care.
- Parameters:
-
point a reference point for the widget, for instance one that the widget should be adjacent or on top of.
- Returns:
- the geometry to use for the desktop. Note that it might not start at (0,0).
This function returns the desktop geometry for an application that needs to set the geometry of a widget on the screen manually. It takes into account the user's display settings (number of screens, Xinerama, etc), and the user's preferences (if KDE should be Xinerama aware).
- Parameters:
-
w the widget in question. This is used to determine which screen to use in Xinerama or multi-head mode.
- Returns:
- the geometry to use for the desktop. Note that it might not start at (0,0).
| QString desktopPath | ( | ) |
The path to the desktop directory of the current user.
- Returns:
- the user's desktop directory
| int dndEventDelay | ( | ) |
Returns a threshold in pixels for drag & drop operations. As long as the mouse movement has not exceeded this number of pixels in either X or Y direction no drag operation may be started. This prevents spurious drags when the user intended to click on something but moved the mouse a bit while doing so.
For this to work you must save the position of the mouse (oldPos) in the QWidget.mousePressEvent(). When the position of the mouse (newPos) in a QWidget.mouseMoveEvent() exceeds this threshold you may start a drag which should originate from oldPos.
Example code:
void KColorCells.mousePressEvent( QMouseEvent *e )
{
mOldPos = e->pos();
}
void KColorCells.mouseMoveEvent( QMouseEvent *e )
{
if( !(e->state() && LeftButton)) return;
int delay = KGlobalSettings.dndEventDelay();
QPoint newPos = e->pos();
if(newPos.x() > mOldPos.x()+delay || newPos.x() < mOldPos.x()-delay ||
newPos.y() > mOldPos.y()+delay || newPos.y() < mOldPos.y()-delay)
{
// Drag color object
int cell = posToCell(mOldPos); // Find color at mOldPos
if ((cell != -1) && colors[cell].isValid())
{
KColorDrag *d = KColorDrag.makeDrag( colors[cell], this);
d->dragCopy();
}
}
}
- Returns:
- the threshold for drag & drop in pixels
| QString documentPath | ( | ) |
The path where documents are stored of the current user.
- Returns:
- the path of the document directory
| emitChange | ( | KGlobalSettings.ChangeType | changeType, | |
| int | arg=0 | |||
| ) |
Notifies all KDE applications on the current display of a change.
This is typically called by kcontrol modules after changing the corresponding config file. Do not call this from a normal KDE application.
| QFont fixedFont | ( | ) |
Returns the default fixed font.
- Returns:
- the default fixed font.
| QFont generalFont | ( | ) |
Returns the default general font.
- Returns:
- the default general font.
| KGlobalSettings.GraphicEffects graphicEffectsLevel | ( | ) |
This function determines the desired level of effects on the GUI.
- Since:
- 4.1
| KGlobalSettings.GraphicEffects graphicEffectsLevelDefault | ( | ) |
This function determines the default level of effects on the GUI depending on the system capabilities.
- Since:
- 4.1
| iconChanged | ( | self, | ||
| int | group | |||
| ) |
Emitted when the global icon settings have been changed.
- Parameters:
-
group the new group
- Signal syntax:
QObject.connect(source, SIGNAL("iconChanged(int)"), target_slot)
| QColor inactiveTextColor | ( | ) |
The default color to use for inactive texts.
- Returns:
- the inactive text color

| KGlobalSettings.TearOffHandle insertTearOffHandle | ( | ) |
Returns whether tear-off handles are inserted in KMenus.
- Returns:
- whether tear-off handles are inserted in KMenus.
| bool isMultiHead | ( | ) |
Returns if the user specified multihead. In case the display has multiple screens, the return value of this function specifies if the user wants KDE to run on all of them or just on the primary On Windows, settings are retrieved from the system.
- Returns:
- true if the user chose multi head
| kdisplayFontChanged | ( | self ) |
Emitted when the application has changed its font in response to a KControl request.
Normally widgets will update their fonts automatically, but you should connect to this to monitor global font changes, especially if you are using explicit fonts.
Note: If you derive from a QWidget-based class, a faster method is to reimplement QWidget.changeEvent(). This is the preferred way to get informed about font updates.
- Signal syntax:
QObject.connect(source, SIGNAL("kdisplayFontChanged()"), target_slot)
| kdisplayPaletteChanged | ( | self ) |
Emitted when the application has changed its palette due to a KControl request.
Normally, widgets will update their palette automatically, but you should connect to this to program special behavior.
- Signal syntax:
QObject.connect(source, SIGNAL("kdisplayPaletteChanged()"), target_slot)
| kdisplayStyleChanged | ( | self ) |
Emitted when the application has changed its GUI style in response to a KControl request.
Normally, widgets will update their styles automatically (as they would respond to an explicit setGUIStyle() call), but you should connect to this to program special behavior.
- Signal syntax:
QObject.connect(source, SIGNAL("kdisplayStyleChanged()"), target_slot)
Returns a font of approx. 48 pt. capable of showing text.
- Parameters:
-
text the text to test
- Returns:
- the font that is capable to show the text with 48 pt

| KGlobalSettings self | ( | ) |
Return the KGlobalSettings singleton. This is used to connect to its signals, to be notified of changes.
| settingsChanged | ( | self, | ||
| int | category | |||
| ) |
Emitted when the global settings have been changed. KGlobalSettings takes care of calling reparseConfiguration on KGlobal.config() so that applications/classes using this only have to re-read the configuration
- Parameters:
-
category the category among the SettingsCategory enum.
- Signal syntax:
QObject.connect(source, SIGNAL("settingsChanged(int)"), target_slot)
| bool shadeSortColumn | ( | ) |

| bool singleClick | ( | ) |
Returns whether KDE runs in single (default) or double click mode. see http://developer.kde.org/documentation/standards/kde/style/mouse/index.html
- Returns:
- true if single click mode, or false if double click mode.
| QFont smallestReadableFont | ( | ) |
Returns the smallest readable font. This can be used in dockers, rulers and other places where space is at a premium.
| QRect splashScreenDesktopGeometry | ( | ) |
This function returns the desktop geometry for an application's splash screen. It takes into account the user's display settings (number of screens, Xinerama, etc), and the user's preferences (if KDE should be Xinerama aware).
- Returns:
- the geometry to use for the desktop. Note that it might not start at (0,0).
| QFont taskbarFont | ( | ) |
Returns the default taskbar font.
