Graphics Panels are similar to the graphical user interface (GUI) of an application. Once built they allow a user that has no knowledge of Vehicle Spy to perform complex tasks with the program. This tutorial will build a very basic Graphical Panel with only two tools. It is possible to have dozens of tools across multiple panels.
Select Measurement > Graphical Panels from the main menu.
Select the LED Control (Figure 1:) at the bottom of the screen. Click anywhere inside the Graphical Panel to place the LED. Next, select the Power Control (Figure 1:) at the bottom of the screen to add an on/off button. Click anywhere in the graphical panel to place the on/off button.
Select the LED that was placed in the graphical panel. Once the LED is selected, find the Caption property (Figure 2:), and change it Playback Status. Select the Show Caption (Figure 2:) and select 1-Yes from the pulldown. Select your On/Off button and change the OnText property to Running and the OffText property to Stopped. The caption for the On/Off Button changes depending whether it is set on or off.
Click the LED, then double click the Signal property from the right. This will open the Expression Builder. From here, select the App Signals (Figure 3:) category from the left. Double click the Playback Indicator signal (Figure 3:) to enter it into the expression field. OK (Figure 3:) will confirm the changes. By default when the signal value that the LED is attached to equals 1, the LED will be lit. Now, do the same for the On/Off button, except this time double click the Playback Control application signal. The On/Off button will change the signal value to either a 1 or a 0 depending on it's position (on or off).
