Toolbar

Toolbars können verschiedene Widgets wie Buttons, Togglebuttons, Radiobuttons oder (Unter-)Menüs enthalten. Die Erstellung und Bearbeitung erfolgt analog zum Menü über "Edit...".

Statusbar

In der Statusbar können kurze Meldungen/Nachrichten eingeblendet werden. Die Meldungen werden analog zu einer Liste behandelt, das Widget bietet die Funktionen push und pop.

Python

Um Nachrichten an die Statusbar zu senden, bedient man sich einfach der Funktion

widget.push(content_id,message)

Wenn man Meldungen ausschließlich "obendrauf" einblendet, kann man als content_id eine beliebige Zahl angeben, zum Beispiel 0.
