  • Adding custom graphic objects to dialogs


    I have a dialog created with GUI_CreateDialogBox(), I want to add my custom graphic objects - bmp images, digital clocks to this windows. I've added a custom handler for dialog callback (on receiving WM_PAINT message). But how to invalidate window? I've created a timer for this goal, set it to 1 second (1 second is okay for me) and set window be invalidated by timer's event (WM_TIMER message). Is it a good choice?

    Best regards
  • Hello Anton,

    In order to show a clock a timer sounds like a good choice. I recommend invalidating just the rectangle which the clock is placed on. If the complete dialog is invalidated all objects in the dialog are redrawn what may be time consuming.
