From http://code.mythtv.org/trac/ticket/9658 :
> Steps to reproduce:
> 1, Go into Watch Recordings
> 2, Highlight any recording
> 3, Press I
> 4, Press F1
> At this point the frontend seems to hang. You cannot scroll the program info window up or down and cannot press Esc to back out. However, a second press of F1 brings it back to life.
> Changes (by paulh):
> * status: new => closed
> * resolution: => Invalid
> It's actually working as it should.
> The web browser mythui widget needs to know where the key presses should
> be processed either by myth or by the Qt QWebView browser widget we use
> behind the scenes. For example if you press 'm' should that open the popup
> menu or should it enter an 'm' in an edit box on a web page? In order to
> toggle where key presses get handled there is a TOGGLEINPUT key binding
> (set to F1 by default) which switches where key presses get handled.
> Without it there would be no way to enter many keys like 'm' or 'i' in a
> search edit on a web page for example because myth would get the key
> before the web page.
Thanks for the explanation. I don't use the web browser in MythTV so
wasn't aware of the F1/TOGGLEINPUT behaviour. However, as far as I can
tell, the program info window doesn't have anywhere in it that accepts
input, unlike a web page, so can you not tell the widget to ignore the
TOGGLEINPUT when appropriate?
In my case, I found this problem in the program info window when I
accidentally pressed F1 instead of Esc on a keyboard due to their close
proximity. As nothing appeared on screen, I thought it had hung. Maybe
an alternative fix would be for an some kind of indication when
TOGGLEINPUT has been pressed, although as I say, in this particular
screen I don't think TOGGLEINPUT should do anything.
