           Summary: FLTK widgets do not redraw
           Product: ReactOS
           Version: TRUNK
          Platform: x86 Hardware
        OS/Version: ReactOS
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: Win32
        AssignedTo: ros-bugs at reactos.org
        ReportedBy: obeythepenguin at gmail.com
         QAContact: ros-bugs at reactos.org

Widgets in FLTK 1.3 applications are not redrawn in response to
Fl_Widget::redraw() calls; one must force a redraw by moving or resizing the
application window.  This can be seen in Dillo-Win32
(http://dillo-win32.sourceforge.net/), for example, when a newly-loaded page is
displayed as a blank box until the browser window is moved or resized; it also
affects other things like the tabs widget in Dillo's Preferences dialog.

I am aware that FLTK widgets do not redraw automatically when updated; the
application in question calls Fl_Widget::redraw() when necessary, and has been
confirmed to work correctly on several Windows systems (including NT 4.0, 98
SE, and XP).  I intend to test other FLTK applications when I get a chance, to
confirm that this behavior is not specific to Dillo.
