I have a problem of losing the keyboard focus with my cascaded popup
Athena widgets (X11R3 (RISCwindows3.2 on a MIPS RS2030)).
I have multiple popup windows some of which have text widgets for the
user to enter text from the keyboard. The problems occurs when I
popup (using XtPopup) a simple "Yes" "No" type window with
XtGrabExclusive. I have the callbacks from the "Yes" and "No" button
widgets doing the XtPopdown. These popups work by themselves but the
seem to keep the Keyboard Focus. The Keyboard Focus does not return to
the previous window (ie. the one with the text input fields). It
seems to be worst if the pointer enters and leaves the window
containing the buttons.
By putting an explicit XtRemoveGrab call before my XtPopdown call I
have managed to get one of text entry windows to get the Focus back
99% of the time. (I get some Toolkit warnings - I think are cause when
XtPopdown does its XtRemoveGrab - because the widget is no longer on
the grab list). But I have another text entry window which is popped
up from one of the buttons in the first (it is Exclusive too) ... and
once it loses the Focus it never gets it back. I have tried an
XtSetKeyboardFocus before I popup this window but it doesn't help.
I am running my application WITHOUT any window manager.
I think that doing my XtPopdown from my callback is causing the
problem. I have searched through all the X demo and contrib source
code that we received but there are no good examples of handling the
simple "Yes" "No" type popup windows with Athena widgets. Any
pointers to good examples would be appreciated. If what am doing is
the "right" thing - does it work better with other widgets (ie motif)?
Please feel free to e-mail any suggestions. I'll post a summary if I
get any good responses.
