Front Panel Window:Transparency Property
Short Name: FP:Transparency
Installed With: Base Package (Windows, Mac OS)
Class: VI Properties
Sets the window transparency level of the VI. The level of transparency is a percentage where 0 is opaque and 100 is invisible. This property returns an error if you specify a value outside the range of 0 to 100. If you set the transparency level to 100, the VI becomes invisible and uncontrollable from the front panel. You must stop the VI on the block diagram for the front panel of the VI to become visible. You must set the Front Panel Window:Run VI Transparently property to TRUE for this property to have any effect. The default value for the Front Panel Window:Run VI Transparently property is FALSE, in which changing this property has no effect.
This property is similar to the Window Runs Transparently option in the Customize Window Appearance dialog box.
