Problem mit meiner GUI/GridbagLayout

[edfred]

Hallo zusammen,

ich habe das erste Mal mit dem GridbagLayout herum expermentiert und es funktioniert leider nicht so wie ich es gerne hätte.
Meine ganzen Labels und Textfelder, die in einem mainPanel liegen erscheinen nicht sofort, sondern erst wenn ich das Frame verklineere oder vergrößere. :autsch:
Ich habe vor ein Adressbuch zu erstellen, aber nur zu Übungszwecken, da ich in der Swing-Programmierung noch ziemlich grün hinter den Ohren bin.

Ich bin für jeden Hinweis und Verbesserungstipp sehr Dankbar.

Das ist mein Code für die GUI:

package de.home.addressbook.gui;

Das liegt daran, dass setVisible zu früh aufgerufen wird.

Hi,

da hast du recht. Danke schön. Ich glaub den Fehler hätte ich nie entdeckt. 🙂
