[Java-gnome-developer] Set window icon without org.gnome.gtk.Window?

[Ethan Tira-T. <ej...@cm...>]

I'm guessing the answer will be no, in which case consider this a feature request, but basically I have a Java application, and I just want to set the application icon for the window in the task switcher so it's not just the generic java app icon.  I don't want to have to rewrite all the UI stuff though just for this minor issue.  Especially since that would kill the portability with other platforms.

Perhaps this can be done via the GTK look and feel properties?  Is that done in this group or is that another project (can you give a pointer?)

Thanks,

Maybe the Gtk.setDefaultIcon(Pixbuf) function is what you are looking
for.

Ah, almost... I got excited there, but this only seems to work for windows which extend org.gnome.gtk.Window; if it uses JFrame it only gets the generic icon.

Just for reference how I've seen this addressed elsewhere, on OS X I can pass java -Xdock:icon=my_icon.png without having to modify any code... I quite like that solution for a basic branding issue like this.  Alternatively, OS X also uses system properties to control some UI options via the look and feel module (e.g. -Dapple.laf.useScreenMenuBar=true), so I'd expect they could have done the icon setting the same way... However, setting via -X to java probably lets them load the icon right from the get-go, to display even before the classes are done loading into memory... *shrug*

Anyway, doing some more searching, turns out Java 6 has this issue covered with a newly introduced "setIconImage" for the java.awt.Window, so I'm all set!
