Gtk peer set for Java and iconify/deiconify

[Nicholas Allen - Sun Ireland - Software Engineer <nicholas allen ireland sun com>]

Hi,

We are working on a peer set for Gtk (1.2) for Java and are having 
problems with iconification/deiconification. We sent an email earlier 
regarding this and received some very helpful feedback (thanks!) but 
there are still a few issues we haven't been able to resolve.

We have manged to iconify the window by using X call to XIconifyWindow 
and this obviously works. We can work out when the window has been 
deiconified or iconified by the user by listening in to the "map-event" 
and "unmap-event" signals. When we get these we check if the map was 
because we made the window visible or if the user deiconified it and 
post events to the event queue accordingly.

The problem is that Java treats iconify and visible states as two 
separate enteties (so there are 4 possible states for a window - visible 
and deiconified, visible and iconified, invisible and iconified and 
visible and iconified). This means that if we hide a window and then 
iconify it and then make it visible it should be displayed as a visible 
icon . Unfortuantely, calling gtk_widget_show() on a top level window 
that has been hidden and iconified deiconifies it (but we want it to 
appear as an icon).   

Does anyone know how to achieve this?

Any help would be much appreciated.

Thanks in advance,
