Member Function Documentation

◆ observerName()

QString BrushHudDock::observerName ( )

inlineoverridevirtual

Reimplemented from KoCanvasObserverBase.

Definition at line 21 of file brushhud_dock.h.

21{ return "BrushHudDock"; }

◆ setCanvas()

void BrushHudDock::setCanvas ( KoCanvasBase * canvas )

overridevirtual

re-implement this method in your canvas observer. It will be called whenever a canvas becomes active. Note that you are responsible for not connecting more than one time to the signals of a canvas or any of the QObjects you can access through the canvas.

Implements KoCanvasObserverBase.

Definition at line 25 of file brushhud_dock.cpp.

{
    setEnabled(canvas != 0);
 
    if (m_canvas) {
        m_canvas->disconnectCanvasObserver(this);
    }
 
    m_canvas = dynamic_cast<KisCanvas2*>(canvas);
 
    if (m_canvas && m_canvas->viewManager() && m_canvas->resourceManager()) {
        m_brushHud = new KisBrushHud(m_canvas->viewManager()->canvasResourceProvider(), this);
        setWidget(m_brushHud);
    }
    else {
        setWidget(nullptr);
    }
}

◆ unsetCanvas()

void BrushHudDock::unsetCanvas ( )

inlineoverridevirtual

Re-implement to notify the observer that its canvas is no longer among the living. The daisies, it is pushing up. This means you don't have to disconnect, it's dead.

The old canvas should be deleted already, so if you stored a pointer to it, don't touch!

Note that currently there is a bug where in certain specific circumstances unsetCanvas can be called when it shouldn't, see for example KWStatisticsDocker for a workaround for this problem.

Implements KoCanvasObserverBase.

Definition at line 23 of file brushhud_dock.h.

23{ m_canvas = 0; setEnabled(false);}
