This function returns the desktop geometry for an application that needs to set the geometry of a widget on the screen manually.

-
w the widget in question. This is used to determine which screen to use in Xinerama or multi-head mode.

- the geometry to use for the desktop. Note that it might not start at (0,0).
Definition at line 719 of file kglobalsettings.cpp.
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).
Definition at line 702 of file kglobalsettings.cpp.
QString KGlobalSettings::desktopPath | ( | ) | [static] |
The path to the desktop directory of the current user.
- Returns:
- the user's desktop directory
Definition at line 601 of file kglobalsettings.cpp.
int KGlobalSettings::dndEventDelay | ( | ) | [static] |
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
Definition at line 214 of file kglobalsettings.cpp.

void KGlobalSettings::kdisplayFontChanged | ( | ) | [signal] |
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.

void KGlobalSettings::kdisplayPaletteChanged | ( | ) | [signal] |
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.

void KGlobalSettings::kdisplayStyleChanged | ( | ) | [signal] |
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.
Note: If you derive from a QWidget-based class, a faster method is to reimplement QWidget::changeEvent() and catch QEvent::StyleChange. This is the preferred way to get informed about style updates.
