1. Righ-Click the Panel
2. Select an object from the list BUT NOT from the top two menus, choose 'Rectangle'.
3. Draw the rectangle then double-click it.
4. The 'Animations Properties' window opens.
5. Select the 'Touch' tab, Enable Touch and set to 'Run Script when up'. Write the script here.
Once you master these "Animation Properties" there is little that you cannot make this thing do, you will be limited only by your imagination.
The top two menu selections here contain the "Quick" part of the QuickPanel but they are not very flexible, WYSIWYG. Have fun!
