LoadView

Use a (possibly freshly created) coprocessor instruction list to create the current display.

Declaration

Source position: agraphics.pas line 2330

procedure LoadView(

  View: PView

);

Arguments

View

  

A pointer to the View structure which contains the pointer to the constructed coprocessor instructions list, or nil.

Description

Install a new view to be displayed during the next display refresh pass. Coprocessor instruction list has been created by InitVPort(), MakeVPort(), and MrgCop().

If the View pointer is non-nil, the new View is displayed, according to your instructions. The vertical blank routine will pick this pointer up and direct the copper to start displaying this View.

If the View pointer is nil, no View is displayed.

Even though a LoadView(nil) is performed, display DMA will still be active. Sprites will continue to be displayed after a LoadView(nil) unless an OFF_SPRITE is subsequently performed.
