There are two things to worry about here. How do you get the visual feedback you want, and how do you detect the action. Detecting the action is the same as before. You need to detect the button changes via value change events, mouse or key events, etc. Build small state machines to keep track of what you have seen and which transitions are valid. For the visual changes, most of them will be done via property nodes. Towards the bottom, the property node for a Boolean gives you access to the Boolean Text's font and to the properties like Bold that can be changed. > Moreover, if I separate the panel into 3 parts by using 2 mark lines > and hope to paint 3 different colors on the panel, every window having > one color. If you just want three colored sections behind the controls in this panel, place three graphical decorations. LV has built in rectangular decorations, or you can import a bitmap if you like. Use the cycling arrows or Ctl-Shift-J to move the graphics to the back of the controls. If you want this color to change, use an indicator instead -- the color control works pretty well, but so does the ring, the Boolean, and the color ramp. If you want to have three panels displayed in one window, you need to look at using the subPanel feature in LV7. Greg McKaskle
