I have two windows in an application, a GuideWindow and a
RegularWindow. The GuideWindow covers all screens and displays guide
lines that match up with the edges of the contentView in
RegularWindow. When RegularWindow is moved or resized, GuideWindow
updates its display to move the guide lines with it. This is achieved
through windowDidResize notifications and windowDidMove notifications.
when doing a resize, everything works perfectly with the guide lines
updating as the RegularWindow is resized.
However, windowDidMove is only called when the user pauses while
moving RegularWindow. So I subclassed RegularWindow and made
windowDragged send an NSWindowDidMoveNotification (sloppy, I know).
This calls the update method of GuideWindow properly, but it still
doesn't draw until the user pauses.
I've got some NSLogs in the guide update function, so I know it's
being called, but no drawing. I've tried sending the display method to
all of the GuideWindow views and to the GuideWindow itself with no
avail. I've also tried updating and flushing the window.
Am I missing something? Are only certain drawing events called in the
event loop when a window is being dragged? Could this have to do with
window backing? Thanks in advance,
-Garrett
