Hi, I seem to have run into a problem with what is essentially nomenclature..
Since LCL has used Delphi as its template, there's a lot of Windows based conventions, but that doesn't totally map to other systems. For instance, TForm.Handle in windows repesents the tag that the OS gives to the rectangle I see on screen. I would have thought that each underlying widgetset interface would then use this to maintain some consistency at a higher level, eg on OSX, this would be filled with the WindowRef that OSX uses. However, I cannot see this happening (unless I'm looking in the wrong place). TCarbonWindow has a fWindowRef field and property that references it, but this is at widgetset level, and so not visible to TForm. I see the HandleAllocated and GetReferenceAllocated code lying around, but they don't seem to tell me what I'm after. What I'd like to know is if I have a function in OSX that is asking for a form's WindowRef, do I pass it self.Handle, or is there something else I should be using. At the moment it is not working as I would hope. For instance calling GetWindowAttributes(WindowRef(self.Handle),myAttributes) gives me an exception each time. Any ideas on what I should be looking for?
