I have a
GeDialogwindow now. and i want to close it when my mouse click in anywhare.
I can get the mouse click event in
GeDialog.Message(), but it's just work inside of dialog.
So i think maybe i need to get the global input event . But i can't find any method in SDK.
How do i do that?
Solved Can i get global input event ?
Thank you for reaching out to us. Yes, you can get the 'global' input event with
c4d.gui.GetInputEvent, but the problems are that:
- When you click outside of the bounds of a dialog it will lose focus, and Cinema 4D will stop calling your dialog, and consider it dormant until it gains focus again. So, you must get hold of this focus event (
- A dialog losing focus seems to flush the input event queue, which makes sense, but limits your options a bit.
Find below a solution which likely does what you want to do. I would also recommend opening the dialog as a popup dialog, so that users do not get confused as to why your dialog behaves differently than 'normal' dialogs.
