3 | // TODO: When the windows is only resized a little bit (A few pixels), the window should not centered |
||
4 | // Idea: Calc the width and height of ALL pictures, and then size the form to the biggest value? |
||
5 | // BUG: if bitmap is not existing, then the error "ReadBitmapFile(): Unable to open bitmap file" appears. Not good. |
||
6 | // BUG: If you drag the window, the dia show will stop playing, but the sound continues! This makes everything out of sync. |
||
7 | // TODO: Ini Parameter if fullscreen is applied or not |
||
8 | // TODO: Check out if hotspot coords should have their origin at the picture or the form position. |
||
9 | // Idea: Savestates. Speedup. Pause. |
||
10 | // Idea: Use Space bar to go to the next decision point. |
