[STR New] Link: http://www.fltk.org/str.php?L2797 Version: 1.3-current (See thread in fltk.general "Tile sample and X_CreatePixmap error") On linux (centos 5.5 for me), building fltk 1.3.x with 'configure --disable-xdbe' and running the test/tile program, when the tiles are moved around such that the 'child window' tile (an Fl_Double_Window itself) is sized to 0 on either W or H, the following X windows errors occur on the console: X_CreatePixmap: BadValue (integer parameter out of range for operation) 0x0 X_CopyArea: BadDrawable (invalid Pixmap or Window parameter) 0x11002b2 This is as far as I could get: o Changing Fl_Double_Window -> Fl_Window prevents the errors. So that seems to make it Fl_Double_Window specific. o The issue is definitely triggered when one of the tiles, probably 'child window' is resized to zero on either W or H. (I never saw negative numbers, so that's not an issue) I determined this by modifying resize() in src/Fl_Double_Window.cxx to print the W/H values. Errors only occur when W or H is zero. o I could easily prevent the problem by adding the following two lines of code to src/Fl_Double_Window.cxx's resize(): void Fl_Double_Window::resize(int X,int Y,int W,int H) { W = (W<=0)?1:W; // <-- ADDED THIS H = (H<=0)?1:H; // <-- ADDED THIS int ow = w(); [..] ..a hack which just prevents windows from possibly being resized to zero or less on W or H. Hopefully one of our X gurus can figure this out; it's hard to trace the problem down, due to X buffering the errors.
