Ahhhh. Didn't consider the wrap around. Here:
- (NSRect)allowedRect;
{
return NSMakeRect(100, 200, 1500, 650);
}
- (NSPoint)cascadeTopLeftFromPoint:(NSPoint)topLeft
{
NSSize cascadeOffset = NSMakeSize(21, -23);
// This window's top left
if (NSEqualPoints(NSZeroPoint, topLeft)) {
topLeft = NSMakePoint(NSMinX(self.allowedRect),
NSMaxY(self.allowedRect));
}
CGFloat proposedRight = topLeft.x + self.frame.size.width;
CGFloat proposedBottom = topLeft.y - self.frame.size.height;
if (proposedRight > NSMaxX(self.allowedRect)) {
topLeft.x = NSMinY(self.allowedRect);
}
if (proposedBottom < NSMinY(self.allowedRect)) {
topLeft.y = NSMaxY(self.allowedRect);
}
self.frameTopLeftPoint = topLeft;
// Next window's top left
return NSMakePoint(topLeft.x + cascadeOffset.width, topLeft.y +
cascadeOffset.height);
}
If you never ever ever want a window to be able to be positioned under a
palette (even if the user moves it there) then you additionally need to
customize the constrain method. Something along the lines of:
- (NSRect)constrainFrameRect:(NSRect)frameRect toScreen:(NSScreen *)screen;
{
// Move Right
frameRect.origin.x = MAX(frameRect.origin.x, NSMinX(self.allowedRect));
// Move Left
frameRect.origin.x = MIN(frameRect.origin.x, NSMinX(self.allowedRect));
// Move upward
frameRect.origin.y = MAX(frameRect.origin.y, NSMinY(self.allowedRect));
// Move downward
frameRect.origin.y = MIN(frameRect.origin.y, NSMaxY(self.allowedRect) -
frameRect.size.height);
return [super constrainFrameRect:frameRect toScreen:screen];
}
