In a nutshell: when an Escape key is pressed in a
setup window, the key event (key<> == Qt::Key_Escape)
is sent to the widget with focus, e.g. a MythLineEdit
widget. When the Escape is generated by lirc, the
widget never gets the key event. Why? And, how do I
fix this?
Of course, normally, the MythLineEdit widget will
ignore the escape key and allow a higher level widget
to interpret it. That's the behavior I'm looking for
for lirc-generated events.
The reason I'm asking is I'm trying to fix the last
major problem with a virtual keyboard widget for the
mythlineedit widget. If I hit escape from the
keyboard, the mythlineedit properly intercepts the key
event, but not if I do it through the remote. If I
use the remote, the top level window interprets the
escape event, and exits to a higher menu or to a
previous window screen. The popup widget I made gets
stuck on the screen if the window goes to a previous
window screen.
In mythmainwindow.cpp, for the method
MythMainWindow::getTarget(QKeyEvent &key), I find the
lines
// Yes this is special code for handling
the
// the escape key.
if (key.key() == d->escapekey &&
focus_widget->topLevelWidget())
key_target =
focus_widget->topLevelWidget();
I tried commenting these lines out, but it didn't
help.
Thanks for the help! Sorry, I'm still new to myth.
