~KisView()

KisCanvas2 maintains direct connections to the image, so we should disconnect it from the image before the destruction process starts

Member Function Documentation

addStatusBarItem()

void KisView::addStatusBarItem	(	QWidget *	widget,
		int	stretch = 0,
		bool	permanent = false )

This adds a widget to the statusbar for this view. If you use this method instead of using statusBar() directly, KisView will take care of removing the items when the view GUI is deactivated and readding them when it is reactivated. The parameters are the same as QStatusBar::addWidget().

canvasBase()

KisCanvas2 * KisView::canvasBase

(

)

const

Returns

the canvas object

Definition at line 427 of file KisView.cpp.

{
    return &d->canvas;
}

References Private::canvas, and d.

canvasController()

KisCanvasController * KisView::canvasController

(

)

const

The CanvasController decorates the canvas with scrollbars and knows where to start painting on the canvas widget, i.e., the document offset.

canvasIsMirrored()

bool KisView::canvasIsMirrored

(

)
