Hi!
I am trying to do some nice drawing using CoreAnimation. It all works
fine, except for a long series of "CoreAnimation: rendering error 500"
messages.
However, as soon as I try to use my window in the context of a modal
session, only the background is draw. The actual animated layers are
missing.
What am I doing wrong?
- (NSUInteger)beginModalWindow:(NSWindow *)modalWindow
{
NSModalSession currentModalWindowSession;
if ([[modalWindow delegate]
respondsToSelector:@selector(windowWillBeginModal:)]) {
[[modalWindow delegate] windowWillBeginModal:modalWindow];
}
[modalWindow makeKeyAndOrderFront:self];
if ([[modalWindow delegate]
respondsToSelector:@selector(windowDidBeginModal:)]) {
[[modalWindow delegate] windowDidBeginModal:modalWindow];
}
currentModalWindowSession = [NSApp
beginModalSessionForWindow:modalWindow];
NSUInteger result = NSOKButton;
while(1) {
NSInteger response = [NSApp
runModalSession:currentModalWindowSession];
if (response == NSRunAbortedResponse) {
result = NSCancelButton;
}
if (response != NSRunContinuesResponse) {
break;
}
}
[NSApp endModalSession:currentModalWindowSession];
if ([[modalWindow delegate]
respondsToSelector:@selector(windowWillEndModal:)]) {
[[modalWindow delegate] windowWillEndModal:modalWindow];
}
[modalWindow orderOut:self];
if ([[modalWindow delegate]
respondsToSelector:@selector(windowDidEndModal:)]) {
[[modalWindow delegate] windowDidEndModal:modalWindow];
}
return result;
}
Best,
Pierre Bernard
