It's a long shot, but I am hoping that someone might recognize my problem from this general description. I tried to reduce my code to a test case, but it works there. After spending an entire day on this problem, I am stumped.
I have a bunch of labels and entries in a vbox. I added the vbox to page 1 of a notebook (the second page). Everything worked fine. I encountered a situation in which some of the labels and entries did not fit on the page, so I put the vbox in a viewport, the viewport in a scrolledwindow, and I added the scrolledwindow to the notebook instead of the vbox. Now when I go to the mode in which the notebook is visible I find that page 0 appears, but when I select page 1 I see nothing. If *after exposing (the blank) page 1* I leave the mode in which this notebook is active and then return, the contents do appear. The contents appear promptly when I add the vbox to the page directly, but when the same vbox is inside a scrolledwindow with viewport they appear only after trying once to view them, switching to a mode in which the notebook is not visible, then returning. My first thought was show_all. However, if that were the problem then it would not work to leave and return. In any case, I do a show_all on the scrolledwindow. I modified the code so that page 1 appears initially when I enter the mode in which the notebook is visible. In that case, the contents of page 1 appear immediately, but when I switch to page 0 I now see none of the widgets that reside inside the scrolledwindow with viewport on that page (a combobox that is not inside the scrolledwindow with viewport is visible). (And incidentally, I cannot make them appear by leaving the mode in which the notebook is visible and returning, although that procedure does make the contents of page 1 appear in the unmodified code. However, when I activate the combobox, the contents of page 0 appear instantly.) If I further modify the code so that the vbox on page 0 is added directly to page 0 without the scrolledwindow with viewport, then all the contents of page 0 appear as soon as I select page 0. The problem seems to be related to a scrolledwindow with viewport on a hidden page of a notebook. However, in my test program I put a bunch of labels in a vbox in a viewport in a scrolledwindow on two pages of a notebook and both pages appear without coaxing. Any suggestions greatly appreciated. -- Jeffrey Barish _______________________________________________ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
