GUI incompatibility

[Andreas Höschler via Discussion list for the GNUstep programming environment]

Hi Fred,

I am still trying to get my apps to work under GNUstep. I have already worked 
around a couple of incompatibilities between Cocoa and GNUstep that caused 
trouble. 

I now ended up at the following problem:

I have some NSView subclass on a window

        ValueElementCarrier : ElementCarrier : ComponentCarrier : 
ControlCarrier : NSView

ValueElementCarrier has a subview

    FormTextField : NSTextField

over its complete rect. 

@implementation FormTextField

- (void)mouseDown:(NSEvent *)theEvent
{
   NSLog(@"%@ mouseDown ..", self);
    ...
    [super mouseDown:theEvent];
}

- (BOOL)becomeFirstResponder
{
   BOOL result = ([(FBFormWindow *)[self window] designMode] ? NO : [super 
becomeFirstResponder]);
   NSLog(@"%@ becomeFirstResponder %d", self, result);
   return result;
}

- (BOOL)acceptsFirstMouse: (NSEvent*)theEvent
{
   BOOL result = [super acceptsFirstMouse:theEvent];
   NSLog(@"%@ acceptsFirstMouse %d", self, result);
   return result;
}

@end


When I click on this FormTextField on MacOSX I get

13/05/20 17:23:40,783 InterfaceBuilder[93679]: <FormTextField: 0x102cd30> 
acceptsFirstMouse 1
13/05/20 17:23:40,783 InterfaceBuilder[93679]: <FormTextField: 0x102cd30> 
becomeFirstResponder 0
13/05/20 17:23:40,784 InterfaceBuilder[93679]: <FormTextField: 0x102cd30> 
mouseDown ..

When I do the same on GNUstep I get

13/05/20 17:23:40,783 InterfaceBuilder[93679]: <FormTextField: 0x102cd30> 
becomeFirstResponder 0

but no call of acceptsFirstMouse and no call of mouseDown!?  This renders my up 
inoperable! :-(

Any idea? Should this behaviour be fixed in GNUstep (handled equally)? 

Thanks,

 Andreas
