Is there an easy and portable way of telling a form to display its system menu, for example in rsponse to a right-click? I'm trying to do something without border etc. (to suppress all sizeability and the title bar) but still want an easy way of moving it.

Is there an easy and portable way of extending the system menu with e.g. an entry to pop up an "about" box?

Apologies if these are FAQs, I'm still trying to get to grips with the documentation.

No.
Under X-Windows, you have no control whatsoever over the system menu. It is entirely under control of the window manager.

Thanks Michael, noted. Is it possible to lock down a form's dimensions even if the title bar is displayed? So far with GTK2 I've had little success.

Use constraints propery.

Thanks Paul, should have thought of that. I guess that's what comes of being used to a rather old copy of Delphi.

I wonder if I could ask something related: I'm setting forms to poDefaultPosOnly but they're still appearing in the designed location. Am I missing something obvious here as well? :-)

Either a bug or gtk2 does not know how to place at default position.

Usually developers position their form at screen center, so other values can be less tested.

As Michael mentioned, it it totally out of your control under X11, but you could always add some "grab panel" in your window. When the user clicks that and holds the mouse button down (or even on the background canvas of the form)... you can let the user move the form that way.

If've done this before (with fpGUI), but most systems have a keyboard shortcuts to allow this anyway. eg: under X11 you can normally do Alt+Click and drag a window around while holding the Alt and mouse button down.

Windows has a keyboard shortcut as for as I remember, and then allows you to move the window with the arrow keys.

A visible grab panel of some sort is a definite option, as long as it can be done portably. Otherwise I'll simply use the popup menu to turn the title bar on or off- I think that should work.

True, but I'm uneasy about forcing users to have to remember this sort of thing. One of the major benefits of Windows (and comparable GUIs) was that it displayed a menu so that users didn't have to remember special key combinations.

I should be compiling this program for gtk, gtk2 and Qt later, I'll report back.
