Greetings,
I've been attempting to develop a Plasma applet using Python. I'm having an
issue, however, with the height of the Plasma::TreeView being artificially
constrained if I embed it in a Plasma::TabBar. If I put the TreeView directly
onto the plasma applet without the TabBar, the height of the TreeView expands
to take up all available space in the window. If, instead, I place the
TreeView in a TabBar, the height of the TreeView will not expand past a
certain point (the width does not seem similarly constrained). I've tried
setting the maximum height on both TabBar and the inner TreeView element
(using setMaximumHeight) to no avail.
I may be missing something obvious, as I'm still very new on Plasma
development (and Python as well), but scoured the Internet and could not find a
solution to the problem. If this is the wrong venue to ask this question,
please let me know where else to go, otherwise, can anyone let me know what
I'm missing please? I've attached sample code in Python which demonstrates
the issue (it currently calls init_tabs, which creates the TreeView inside a
TabBar. If I switch it to calling init_tree, it does not put the TreeView
inside the TabBar, and the TreeView expands without limit as the window is
expanded vertically).
System: Debian Squeeze with
Python 2.6.5+
KDE Development Platform 4.4.4
Qt: 4.6.3
Thanks,
Glenn.
