Ich möchte eine Komponente für Dialoge programmieren, die Aussieht wie das erste Bild. Was ich bislang habe, sieht allerdings aus wie das zweite Bild.
1.) Ich frage mich, woher der Fenster-Balken unter der Titelleiste kommt.
2.) Wie lässt sich das Look&Feel realisieren, dass man bei gedrückter Maustaste über dem gelb-schwarzen Balken das Fenster verschieben kann?
3.) Der weiße Rahmen um das Bild ist transparent, und sieht nur auf dem Screenshot weiß aus. Allerdings nimmt er immer die Farbe an von dem Fenster das darunter liegt während er aktiv ist und bewegt wird, ist also nicht wirklich transparent. wie kann ich das ändern?
4.) Wie kann ich den InternalFrame modal anzeigen lassen, während weitere InternalFrames geöffnet sind?
hier der Sourcecode:
