so hab hier nen programm geschrieben das mir bei meinem layout problem weiterhelfen soll..
leider ist bei dem programm ein kleines problem aufgetreten das ich so net versteh...
also folgender effekt:
Variante 1:
- ich starte das programm
- drücke den button LI
--> alles ok es wird das gelbe panel angezeigt
Variante 2:
- ich starte das programm
- drücke den button 1
--> nichts passiert
Variante 3:
- ich starte das programm
- drücke den button 2
--> nichts passiert
Variante 4:
- ich starte das programm
- drücke den button LI
- drücke den button 1
- drücke den button 2
--> Gelbe Feld ok -> Linke Feld ok -> Rechte Feld wird nicht angezeigt
Variante 5:
- ich starte das programm
- drücke den button LI
- drücke den button 2
- drücke den button LI
- drücke den button 1
- drücke den button 2
--> nur so werden alle angezeigt...
Wenn ich bei variante 2 und 3 jedoch das fenster runter klappe und wiederhoch werden meine scrollpanels angezeigt... also dachte ich es liegt viellicht am repaint und hab nach jedem buttondruck auch ein repaint der einzelnen panels eingebaut -> kein effekt...
wieso ist das so?
und was kann ich gegen tun?
thx Kala
