Constructor & Destructor Documentation

KisPopupPalette()

KisPopupPalette::KisPopupPalette	(	KisViewManager *	viewManager,
		KisCoordinatesConverter *	coordinatesConverter,
		KisFavoriteResourceManager *	manager,
		const KoColorDisplayRendererInterface *	displayRenderer,
		QWidget *	parent = 0 )

Tablet support code generates a spurious right-click right after opening the window, so we should ignore it. Next right-click will be used for closing the popup palette
