Layertest
The example panel "Layertest"
(<proj_path>/panels/examples/layertest.pnl
)
demonstrates the visibility hierarchy of WinCC OA. With the aid of layer control
integrated into the operation panel (see Layer control), you can see how the layers lie
one on top of each other and that the widgets (complex graphics objects) always lie
above the simple graphics objects.
