In seguito è il disegno:
Ciao Carl, Funziona nei casi più semplici, ma non nel caso di cui sopra. Così sto explaning il codice di cui sopra ora ..
ho un telaio chiamato "TestListControl" con il layout GB. Aggiungere selectDevicesPanel con il layout GB. In selectDevicesPanel: Aggiungere selectNamesInnerPanel con il layout GB In selectNamesInnerPanel: Aggiungere selectNameAddPanel con il layout GB Aggiungere selectTeamPanel con il layout di flusso In selectNameAddPanel: chooseDeviceScrollPane clickToAddDeletePanel selectedNameScrollPane In selectTeamPanel: selectTeamLabel selectTeamComboBox

Soluzione 2
ragazzi ho risolto questo problema io stesso .. thnks per ur coordinamento ..actually ho fatto l'errore di dare weightx e pesante al pannello genitore che esercita la sia la JList e per il riquadro JEditor ... brevemente noi è necessario impostare i parametri di peso per tutti i contenitori padre che contiene alcun componente che si desidera ridimensionare ..
Altri suggerimenti
L'elenco non sarà possibile ottenere molto più grande se si fa questo:
chooseNamesList.setMaximumSize(new java.awt.Dimension(46, 88));
Se si imposta un valore di cella prototipo, il JList non ridimensiona quando i dati vengono modificati.
Vedere la pagina Javadoc JList per il metodo setPrototypeCellValue (Object).
