Everyone watch my code and help me. I'm building a simple program like Paint the windows. Here, I just do the free drawing button.
But when I press the button and draw freehand drawing, then the panel draw the toolbar to copy the image above and press a button every time a new image, it's back button to copy it.
Everyone watch and help her fix. Thank you so much more.
