currently , they are not in an unified way, some warning dialog are coded as error dialog for example.
and, I would like to improve it a bit more, following other gtk graphics apps (gimp/inkscape mainly) and the gnome hig documents:
the alerts will be info , question, warning and error.
the window title: the “action” that popups this dialog.
the primary text: in bold, one sentence summary of the information or suggested action
the secondary text: a more in-depth description of the problem and suggested action
more details can be found in ghig document.
does it make scenes?
