Recently, I am trying to implement a double buffer for gui_win32.c by: 1. rename s_hdc to s_hdc_real 2. creat a off-screen HDC named s_hdc, all the drawing from gui_win32.c should be redirected to it. 3. BitBlt from s_hdc to s_hdc_real after WndProc, the screen should be updated.
It works in most of time, but when I press CTRL+D to scroll down half a screen I find only the bottom half of TextArea has been updated, the top half hasn't been updated yet, there are still old characters before CTRL+D on the top half. I search all the reference of s_hdc and s_textArea but can not find any clue. Can anybody figure out what's wrong here ? -- -- You received this message from the "vim_dev" maillist. Do not top-post!
