I am working on an application in which I am handling key release event over a editable ‘JComboBox’, where on every key release a ‘JPopupMenu’ of the ‘JComboBox’ appears. I want to increase the height so that user will be able to see more items at a glance without scrolling. Can anyone please demonstrate how to set the height of ‘JPopupMenu’ deliberately so that it will show considerable amount of items? So far i have tried this, but it doesn not work.
ComboPopup popup = (ComboPopup) combo.getUI().getAccessibleChild(combo, 0); ((JComponent) popup).setPreferredSize(size); ((JComponent) popup).setLayout(new GridLayout(1, 1));
It wold be nice to see your SSCCE, so I can test whether my proposal works.
