Ich habe in einem Submenü zwei Checkbuttons.
Wenn ich da auf eine Checkbutton drücke, geht aber das Menü wieder zu.
Wenn ich auch den zweiten Checkbutton ankreuzen will, muss ich das Submenü wieder aufmachen.
Ich hätte aber gerne, dass man auch den zweiten Checkbutton ankreuzen kann, ohne dass das Menü wieder zugeht.
Gibt es dafür eine Lösung?

OK, wenn keiner eine Lösung weiß, muss ich eben eine basteln

Habe schon etwas herausgefunden.

Wenn das sub sub Menü in der Cascade zum ersten Mal aufgeht, bekommt man 3 <Configure> events. Später sind es dann 2. Damit weiß man, wo dieses Menü ist und wie breit und wie hoch es ist:

Code: Alles auswählen

try:
    import tkinter as tk
except ImportError:
    import Tkinter as tk


event_count = 0

def onFormEvent( event ):
    dir_event = dir( event )
    global event_count
    print('EVENT COUNT = ' + str(event_count))
    event_count += 1          
    print('_____________________')
    for key in dir_event:
        if not key.startswith( '_' ):
            print('%s=%s' % ( key, getattr( event, key ) ))
    print('------------------------')

Aber das Problem ist: solange das Menü geöffnet ist, geht nichts Anderes. Und wie man das Menü schließt, weiß ich nicht. Außerdem wäre so etwas auch Menü unübliches Verhalten.

Man könnte es natürlich statt als sub sub Menü nur als sub Menü machen und die Cascade in einen Command umfunktionieren und diesesToplevel dann unter dem Command platzieren. Nur ich möchte nicht weiteren Platz in der Menüleiste verschwenden. Außerdem wo wäre die x-Koordinate des commands?

Und selber eine Art von ganzem Menü aus Buttons statt Commands und Cascaden zusammenzubauen, geht mir zu weit.
