QLabel Selection Box Issue
Message 1 in thread
Hi guys,
I am facing some cosmetic issues with QLabels used as
hyperlinks. I have a form with a couple of links
(QLabels) and each of the link opens up a modal dialog
box. After closing the modal dialog box, the link
remains "selected". If somebody clicks all the links,
all of them will remain selected as long as the window
remains open. Please see attached screenshot.
Is there a way to remove this behavior (e.g. to clear
this selection box around the label after click or do
something so that it never gets the selection box at
all when clicked, but respond to the click) ?
Thanks,
Danny

Hi Danny,
This is indeed a bug in the Qt toolkit and I've created a task for the
responsible parties to have this fixed. In the meantime I can provide
you with a esthetically challenged workaround.
The problem is that the label believe it has received focus when it the
link is activated and this state is never cleared. One certain way of
clearing it is to "reset" the label, e.g. by clearing it and resetting
the original text. Below I extract the current sender for the slot and
if it is a QLabel I reset the text. The clear() is needed because trying
to reset the exact same test will be optimized away. I know its not
nice, but it does work around the problem.
public void handleLink(String link) {
QSignalEmitter sender = signalSender();
QDialog d = new QDialog();
d.setWindowTitle(link);
d.exec();
if (sender instanceof QLabel) {
QLabel label = (QLabel) sender;
String originalText = label.text();
label.clear();
label.setText(originalText);
}
}
best regards,
Gunnar
