Hoi Fred,
Mac OS X behaves differently here. The drop works with a pressed
Ctrl-Key. What exactly does a pressed Ctrl-Key mean to GNUstep?
Control changes the operation to link, see _updateOperationMask: in
GSDragView.m:
if (mod & NSControlKeyMask)
{
operationMask = NSDragOperationLink;
}
You may influence this behaviour by implementing
ignoreModifierKeysWhileDragging on your dragging source.
It is also possible that you see the wrong cursor due to the code in
_setCursor not being able to determine, which action you want. This is
rather probable, as the code there is programmed optimistically.
Thanks! After implementing
- (BOOL)ignoreModifierKeysWhileDragging
{
return YES;
}
in my calenderview it worked (like on MacOSX). I will really have to
look into this operationMask issue again as soon as time allows it. I
expect potential to implement things nicer in my code and more OPENSTEP
like. For now I have to live with the current approach (initiating drag
with Ctrl and ignoring modifier keys while dragging).
Thanks a lot,
Andreas
