This is my third program. This program is for drawing. To change the colors, you can just press the ColorPicker Icon. To change the size, you can just press the SizeChanger Icon. Clear the screen? There is a Clear All Icon for you! I hope you will feel this drawing program is nice and MODERN!
You will know how to do it if you see inside. :) P.S. There is a bug in the drawing program: For the first time, if you open the Color Picker, The close icon/some color icons will be hidden. You need to press the center area for twice to show the close icon. This bug is still waiting for fix.
