Re: how to refresh jComboBox in popupMenuWillBecomeVisible

Rui napisal(a):
NB: I added a setSize() method after adding the ComponentListener to
insure that combo size will be calculated before the frame is made visible.

Thanks! It works. I do it finally in this way:

contentPane.addComponentListener(new
java.awt.event.ComponentAdapter() {
public void componentResized(ComponentEvent e) {
contentPane_componentResized(e);
}
});

void contentPane_componentResized(ComponentEvent e) {
System.out.println("content resized");
int frameCurrentHeight = contentPane.getHeight();
double comboYPosition = myCombo.getBounds().getY();
int fontSize = (int)myCombo.getFont().getSize() + 6;
myCombo.setFixedCellHeight(fontSize);
int rowCount = (int)((frameCurrentHeight - comboYPosition) /
fontSize) - 5;
myCombo.setMaximumRowCount(rowCount);
}


thanks
T.
