101844 - GTK needs to generate NS_DISPLAYCHANGED event when the display depth changes

Status: RESOLVED INVALID

(Core Graveyard :: GFX, defect)

This bug was split off from bug 6061. Changing bit depth/# of colors busts
chrome, images

On GTK we need to add a method to nsWindow which is called when the display has
changed:

PRBool nsWindow::ReportDisplayChange()
{
	// nsEvent
	nsGUIEvent changeEvent;
	changeEvent.eventStructType = NS_GUI_EVENT;
	changeEvent.message = NS_DISPLAYCHANGED;
	changeEvent.time = PR_IntervalNow();

	// nsGUIEvent
	changeEvent.widget		= this;
	changeEvent.nativeMsg		= nsnull;

	// dispatch event
	return (DispatchWindowEvent(changeEvent));
}

The call to DisplayWindowEvent will take care of getting the message to the
viewmanager.

This bug is invalid.

There isn't any way to dynamically change the display depth.
To change the display depth you must relaunch the xserver.
