Is it possible to create blinking elements for visualizations (like a traffic light, which have blinking lights)?
It is not directly possible to have a fast flashing text.
One way is to visualize a Boolean in a control-component like described here: https://www.vigo6.com/how-to-display-a-blinking-message-for-a-variable/
Another way is to have a qBool in the Dynamic Variables section of your view, and then toggle this every time then Paint() Method in executed. This Boolean then determine whether to show the text or not. The blink-frequency is though out of your control, and will depend on how often the view is redrawn (how often visualized data changes)
Paint() method override example:
IF My_qBool THEN My_qBool:= FALSE ELSE My_qBool:= TRUE FOR Viewlist_index:= 0 TO NoOfChildren-1 DO IF Viewlist_index = Label_to_flash THEN IF My_qBool THEN Call_viewlist_paint(ViewListIndex:= Viewlist_index) ELSE Call_viewlist_paint(ViewListIndex:= Viewlist_index)
