Hello all,
i have an application running in one toplevel window showing two different
views:
The first is a schmetic overview with possibility of selecting graphical
elements (network
cameras), the second shows network video streams with mplayer which is embedded
in
a table (two instances atm).
The views are created at program start and are switched due to user selection
with the
gtk_widget_show/hide() commands. (View1=Selection is shown and View2=Stream is
hided initially). The implementation of mplayer is done by a wizard created
(and modified) widget
(GtkMplayer, forkes a process with mplayer, provides init(), class_init(),
destroy(), new() realize(),
size_request(), allocate() and expose(); the later four are overridden in the
class).
When switching to View2 everything looks ok (Window 640x480, two QVGA-Streams
in the upper
half of the window). Switching to View1 is also ok, but switching back to View2
the second time results
in a totally oversized window and the mplayer widget also resizes.
Debugging shows that the error occours when switching from View2 to View1: The
Requisition of View2
changes at this moment (!?) to x=17110 and y=17106 and the window tries of
course to match these
values when changing to View2.
Commenting out the signal bindings of the expose events and the overriden
expose-function of the
gtkmplayer-widget avoids the error, but the mplayer isn´t shown then (the
widget gets redrawn/the player
startet if not running in expose_event)
My question: Is there something special i might haven´t done in the class init
so that the size request fails?
Or does somebody know a more appropriate way to show the different contents
(e.g. toplevel windows?)
Best regards Markus
