I have some problem to display lines on windows. I asked same query in FLTK development group and they refer to this group.
I'm attaching a program. link is http://rapidshare.com/files/34618174/test.rar.html program description main class is MainWindow where i create menu, buttom and 2 view windows. I use mouse operations in this class. and pass mouse position to CLineWin class to draw the lines. To draw any line use the mouse. click on left button, drag it and releas the button. I used CLineWin for lines and CImageWin for image. I'm sending a sample so that u can understand the problem in detail and give any solution. In CLineWin::draw() function, i draw the line. Here i need to call Fl_Double_Window::draw(); otherwise line window area window will display as black. If i call Fl_Double_Window::draw() only once then there is no flickering problem. But if i called it everytime then flickering problem. But in case when i call Fl_Double_Window::draw() only once then a new problem is create. If i have drawn a line and now i move the mouse then that line doesn't appear. but if i use Fl_Double_Window::draw() everytime and move the mouse then line appears always. so please have a look and reply _______________________________________________ fltk mailing list [email protected] http://lists.easysw.com/mailman/listinfo/fltk
