Editable JComboBox overlay

[jimjam]

Hi

Do you have an approach for dealing with an overlay on an editable JComboBox? The combo box's editor and caret often draw over the overlay. It doesn't look easy to override the repaint method of the combo box's editor.

Thanks

Please try the solution in the following link for painting overlay in JComboBox.

Thanks, but I'm afraid that doesn't appear to help. My problem is with an editable combo and a JIDE Overlayable.

Something like:

JComboBox combo = new JComboBox(items);
combo.setEditable(true);
JLabel attentionIcon = new JLabel OverlayableUtils.getPredefinedOverlayIcon(OverlayableIconsFactory.ATTENTION));
overlayableComboBox = new DefaultOverlayable(combo, attentionIcon, DefaultOverlayable.SOUTH_WEST);
overlayableComboBox.setOverlayLocationInsets(new Insets(3, 5, 3, 0));

The overlay looks just fine until the caret goes near and starts to erase it. For most controls, the documented solution is to override repaint() and call OverlayableUtils.repaintOverlayable(this). But that doesn't appear to work with an editable combo (because the combo's internal editor component needs repainting rather than the combo). In fact, the same problem occurs if the overlay is placed at the other end, over the drop button icon.

Please try our OverlayableDemo. The major difference is that OverlayComboBox is used instead of JComboBox so that we can override the repaint method.

The demo is working fine. But it hasn't got an editable combo with an overlay on it. When I change the combo to be editable (OverlayableDemo.java. line 540):

comboBox.setEditable(true);

my problem occurs.

Got you. I'm afraid it's hard to get a solution because JComboBox does not have a method like createTextField(). We have to override the repaint() method for the text area component so that overlayable can work.

Thanks,
