RE: Controlling resizing of boxes when a window is resized

["Ian Puleston" <ian underpressuredivers com>]

Thanks - I thought that there would be something simple like that.

The reason that I'm using gtk_widget_set_size_request on the upper box is
that I display a scrolled window in there, and without the size request the
scrolled window is too small and does not expand out to fill the upper area.
I would like to remove that gtk_widget_set_size_request that if I could get
it to expand out.

The code that sets up the boxes and the scrolled window is basically doing
this:

    frameVBox = gtk_vbox_new(FALSE, 0);

    /* Upper box for main display: */
    upperHBox = gtk_hbox_new(FALSE, 10);
    gtk_box_pack_start(GTK_BOX(frameVBox), upperHBox, TRUE, TRUE, 0);

    /* Add scrolled window into upper box */
    scrWindow = gtk_scrolled_window_new(NULL, NULL);
    gtk_box_pack_start(GTK_BOX(upperHBox), scrWindow, TRUE, TRUE, 0);

    /* Lower box for buttons: */
    lowerHBox = gtk_hbox_new(FALSE, 0);
    gtk_box_pack_end(GTK_BOX(frameVBox), lowerHBox, FALSE, FALSE, padding);

    gtk_container_add(GTK_CONTAINER(mainWin), frameVBox);

But the scrWindow window does not expand out to fill the upper part of the
window as I thought that it would. Adding a frame to upperHBox so that I can
see it shows that scrWindow fills upperHBox, but upperHBox has not expanded
out to fill the upper area. Hence I added a gtk_widget_set_size_request() to
force it to the required size.

Any idea on why upperHBox would not be expanding out to the full size of the
upper window (i.e. all of the space above lowerHBox), and how to get it to
do that?

Thanks,
Ian
