Matchbox keyboard

Matchbox keyboard

[Gary Thomas]

Sorry if this isn't the best place to ask...

I have a GUI application running on Poky/Yocto with Sato using
only a touch screen.  My application window takes up the whole
display which is *very* small (320x240).  If I try and accept
text input, I can see the matchbox keyboard try to pop up, but
it immediately ends up behind my application window and thus
is of little use :-(

Is there some way to get the keyboard window to sit above my
application window while it is active?  I've experimented a bit
and I can use the terminal window in this environment but its
window gets sized very small - probably too small for my application.
Is that the only way for the matchbox keyboard and the application
that's using it for input to coexist?

Thanks for any ideas or pointers

This should not be too small, I am pretty sure I have used it on a
device of that size, but it assumes the GUI application is well behaved
and obeys the window manager -- you have to make it respect the size the
WM allocates.

Does the window manager attempt to resize my window when the keyboard
pops up?  I have a simple dialog and I don't see it being resized (if
that's even possible)

In the matchbox case it works through the window stack and works out the
size that is taken up by DOCKS and TOOLBARS (the kbd is a toolbar,
iirc); whatever is left is then given to the other windows (applications
and dialogs). Simplest way to verify if the WM is trying to resize the
dialog is to listen for the ConfigureNotify event and see what sizes are
coming through there (how you do that would depend on the toolkit).
