I have created a custom DialogCellEditor the displays the FontDialog.
When I click in a table cell, the DialogCellEditor appears, I hit return,
and the FontDialog appears just like I expect. I select a font, click
ok, the FontDialog disappears, but the DialogCellEditor is still visible
in the table cell. Clicking another cell will bring up the appropriate
editor for that cell, but the table display becomes corrupted with the
DialogCellEditor. Any ideas on what I might have done wrong, or is this
a bug?

Here is my DialogCellEditor:

package com.ibm.hdwb.data.ui.tableFormatEditor;
import org.eclipse.jface.viewers.DialogCellEditor;
import org.eclipse.swt.widgets.Composite;
import org.eclipse.swt.widgets.Control;
import org.eclipse.swt.widgets.FontDialog;
/**

public class FontCellEditor extends DialogCellEditor
{
/**

*/
public FontCellEditor(Composite parent)
{
super(parent);
} }
/**

*/
protected Object openDialogBox(Control cellEditorWindow)
{
return new FontDialog(cellEditorWindow.getShell()).open();
} }
}

In case you still need an answer, I had the same problem and solved it by overriding the method
createButton() like this:
protected Button createButton (final Composite parent, Font font) {
final Button button = super.createButton(parent, font);
button.addFocusListener(new FocusAdapter() {
public void focusLost (final FocusEvent e) {
if (!_dialogOpen) {
fireCancelEditor();
// generates "pop-down" when user "clicks out"
}
}
});
return button;
}
Then, in method openDialogBox(), be sure to set and unset the boolean _dialogOpen:
protected Object openDialogBox (final Control cellEditorWindow) {
final Dialog dialog = initialiseDialogHoweverYouNeedTo();
_dialogOpen = true;
final boolean ok = (dialog.open() == WizardDialog.OK);
final String result = getResultHoweverYouNeedTo();
_dialogOpen = false;
return result;
}
