A wrapper around QCursor that allows for "themed" cursors.
Currently, the only themed cursor is a hand shaped cursor.
A typical usage would be
setCursor(KCursor::handCursor()); |
| KCursor ()

| QCursor sizeFDiagCursor ()
| sizeFDiagCursor |

| QCursor sizeAllCursor ()
| sizeAllCursor |
[static]

| QCursor blankCursor ()
| blankCursor |
[static]
Returns a blank or invisible cursor (static function).
| QCursor whatsThisCursor ()
| whatsThisCursor |
[static]
Returns a WhatsThis cursor (static function).
| void setAutoHideCursor ( QWidget *w, bool enable )
| setAutoHideCursor |
[static]
Sets auto-hiding the cursor for widget w. Enabling it will result in
the cursor being hidden when
The cursor will be shown again when the focus is lost or a mouse-event happens.
Side effect: when enabling auto-hide, mouseTracking is enabled for the specified widget, because it's needed to get mouse-move-events. So don't disable mouseTracking for a widget while using auto-hide for it.
When disabling auto-hide, mouseTracking will be disabled, so if you need mouseTracking after disabling auto-hide, you have to reenable mouseTracking.
If you want to use auto-hiding for widgets that don't take focus, e.g. a QCanvasView, then you have to pass all key-events that should trigger auto-hiding to autoHideEventFilter().
| void setAutoHideCursor ( QWidget *w, bool enable,
bool customEventFilter )
| setAutoHideCursor |
[static]
Overloaded method for the case where you have an event-filter installed on the widget you want to enable auto-cursor-hiding.
In this case set customEventFilter to true and call
autoHideEventFilter() from the beginning of your eventFilter().

| void setHideCursorDelay ( int ms )
| setHideCursorDelay |
[static]
Sets the delay time in milliseconds for auto-hiding. When no keyboard events arrive for that time-frame, the cursor will be hidden.
Default is 5000, i.e. 5 seconds.
| int hideCursorDelay ()
| hideCursorDelay |
[static]
Default is 5000, i.e. 5 seconds.
Returns: the current auto-hide delay time.
| void autoHideEventFilter ( QObject *, QEvent * )
| autoHideEventFilter |
[static]
KCursor has to install an eventFilter over the widget you want to auto-hide. If you have an own eventFilter() on that widget and stop some events by returning true, you might break auto-hiding, because KCursor doesn't get those events.
In this case, you need to call setAutoHideCursor( widget, true, true ); to tell KCursor not to install an eventFilter. Then you call this method from the beginning of your eventFilter, for example:
edit = new KEdit( this, "some edit widget" ); edit->installEventFilter( this ); KCursor::setAutoHideCursor( edit, true, true ); [...] bool YourClass::eventFilter( QObject *o, QEvent *e ) { if ( o == edit ) // only that widget where you enabled auto-hide! KCursor::autoHideEventFilter( o, e ); // now you can do your own event-processing [...] } |
Note that you must not call KCursor::autoHideEventFilter() when you didn't enable or after disabling auto-hiding.
