hm schade, der JColorChooser ist ziemlich gut. Gibts einen zum freien Download?JPKI hat gesagt.:Nicht in der Java-Standardbibliothek.
hab keine Lust das Rad 50 mal neu zu erfinden.JPKI hat gesagt.:Und selbst wenn es da keinen gibt, sowas ist doch schnell geschrieben, nicht wahr?

Dafür frierst du aber den GUI-Thread ein, so das man garnichts mehr benutzen kann.JPKI hat gesagt.:Ja, aber mit setModal() hätte ich das Problem nicht lösen können.
Dann wäre ja actionPerformed() ausgeführt worden, das hat ja den Typ void, und ich wollte doch ein Font-Objekt zurückgeben.
Was die Vorschau angeht: Du kannst den Quelltext doch nach deinen Vorlieben ändern.
Edit: Das hier ist mein 500ster Beitrag. Mann, bin ich stolz :wink:
Font getSelectedFont()
{
setModal(true);
setVisible(true); // Der Code wird solange angehalten,
// bis der Benutzer das Dialog schließt
// ohne den GUI-Thread zu stoppen
if ( confirmed )
{
return neuer_font;
}
else return alter_font;
Danke 🙂 das habe ich total übersehen, jetzt funktioniert der Dialog.kleiner_held hat gesagt.:createAttributes(); wird ein zweites mal aufgerufen (Zeile 210) damit werden die JCheckBox Instanzen überschrieben.
