Detailed Description

DVErasablePanelView is a ControlView container class that optionally erases (background fills) itself before drawing it's content and children.

The member fEraseBeforeDraw, which defaults to kFalse, determines whether the view erases before drawing. Subclasses can change 

the value of fEraseBeforeDraw. This flag is usually set from the view resource description file.



The member fEraseToInterfaceColor, which defaults to kInterfacePaletteFill, determines what background color is drawn. 

This flag is set from the view resource description file.



In addition the drawing code checks for the presence of an IID_IDYNAMICERASEBEFOREDRAWFLAG (IBoolData) interface on the widget boss,

if present both it and fEraseBeforeDraw must be set to kTrue for the erase/fill to take place.

Member Function Documentation

virtual void DVErasablePanelView::DV_Draw ( dvaui::drawbot::Drawbot *  drawbotP ) const

virtual

override of DVHostedWidgetView::DV_Draw, the droverized ControlView drawing method. Intended for internal use only, but a few simple drawing primitives are available in DVPublicUtilities.h. This implementation sets up an offscreen graphics port and calls the traditional Draw method.

Reimplemented from DVBasePanelView.

Reimplemented in DVPalettePanelView.
