Hi everybody,
i want to set editable a combobox and set selected(highligted) the first index when i pressed F2. The code i write below;
comboBox.addKeyListener(new KeyAdapter(){
public void keyPressed(KeyEvent e) {
if(e.getKeyCode() == KeyEvent.VK_F2){
//?
comboBox.setEditable(true);
}
}
});
how can i set highlighted ?
next time use code tag.
comboBox.addKeyListener(new KeyAdapter(){
public void keyPressed(KeyEvent e) {
if(e.getKeyCode() == KeyEvent.VK_F2){
comboBox.setSelectedIndex(0); // select the first index
comboBox.setEditable(true);
}
}
});
Add a renderer to the combobox (list renderer), and implement the getListCellRendererComponent() method of the interface. Inside that, setBackground(Color) and setForeground(Color) as required based on conditions.
Attach this renderer to the combo box. The renderer should look like this:
class MyCellRenderer extends JLabel implements ListCellRenderer {
public MyCellRenderer() {
setOpaque(true);
}
public Component getListCellRendererComponent(
JList list,
Object value,
int index,
boolean isSelected,
boolean cellHasFocus)
{
setText(value.toString());
setBackground(isSelected ? Color.red : Color.white);
setForeground(isSelected ? Color.white : Color.black);
return this;
}
}
Thanks every body, this solution is another alternative,
JTextComponent editor = (JTextComponent) comboBox2.getEditor().getEditorComponent();
editor.setCaretPosition(((String)comboBox2.getSelectedItem()).length());
editor.moveCaretPosition(0);
