From 755f354ebe0a2f9c3ee287c53013279fd864ebbe Mon Sep 17 00:00:00 2001 From: Albrecht Schlosser Date: Wed, 9 Jun 2010 08:36:25 +0000 Subject: Fixed X11/XDBE double buffering (STR #2152, #2197). Both bugs could only be seen if configure was run with --enable-xdbe (default in FLTK 1.3, optional in FLTK 1.1). src/Fl_Double_Window.cxx/Fl_Double_Window::resize(): STR #2152: deallocate back buffer when window is enlarged in any dimension to force allocation of a new back buffer. This appears to be necessary for some window managers (e.g. Cygwin). src/Fl_Overlay_Window.cxx/Fl_Overlay_Window::flush() and src/Fl_Double_Window.cxx/Fl_Double_Window::flush(): STR #2197: make sure that the entire overlay window will be drawn after a window redraw, because Fl_Double_Window::flush(1) erases the overlay as documented. git-svn-id: file:///fltk/svn/fltk/branches/branch-1.3@7636 ea41ed52-d2ee-0310-a9c1-e6b18d33e121 --- src/Fl_Overlay_Window.cxx | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'src/Fl_Overlay_Window.cxx') diff --git a/src/Fl_Overlay_Window.cxx b/src/Fl_Overlay_Window.cxx index 8acb4af35..581c7057d 100644 --- a/src/Fl_Overlay_Window.cxx +++ b/src/Fl_Overlay_Window.cxx @@ -61,7 +61,7 @@ void Fl_Overlay_Window::flush() { return; } #endif - int erase_overlay = (damage()&FL_DAMAGE_OVERLAY); + int erase_overlay = (damage()&FL_DAMAGE_OVERLAY) | (overlay_ == this); clear_damage((uchar)(damage()&~FL_DAMAGE_OVERLAY)); Fl_Double_Window::flush(erase_overlay); if (overlay_ == this) draw_overlay(); -- cgit v1.2.3
