In XCode by adding these methods to your NSView subclass can prevent the window from becoming active when clicking on it:
- (BOOL)shouldDelayWindowOrderingForEvent:(NSEvent )theEvent {
return YES;
}
- (BOOL)acceptsFirstMouse:(NSEvent )theEvent {
return YES;
}
- (void)mouseDown:(NSEvent )theEvent {
[[[NSApp]] preventWindowOrdering];
}
In Windows platform It is done by this simple code:
HWND hWnd = FindWindowW((String("FM") + fmxForm->ClassName()).c_str(),
fmxForm->Caption.c_str());
SetWindowLong(hWnd, GWL_EXSTYLE,
GetWindowLong(hWnd, GWL_EXSTYLE) | WS_EX_NOACTIVATE);
How can I subclass NSView to prevent my FMX TForm becoming active when clicking on it?

It is possible using NSPanel with NSNonactivatingPanelMask flag. The NSView of fmx form should become child of NSPanel. I have written a helper class which works for both Windows and Mac platforms (Works on XE4):
Usage of above unit:
If frmKeyboard is your Main Form then do not put above code in form constructor, It is recommended to put it in OnShow.
Note: WindowHandleToPlatform doesn't seem to exist in XE3 so that line can be replaced with
