Display_open_window_interface

Working with the "Display_open_window_interface"

Display_open_window_interface is a subcomponent that lets you to open a view via program code.

The view will open on top of the current visualization - the functionality known as a pop-up window for example.

You use the instance constant root_view_to_open to pick the view to open.

The views that you can pick are either a view for control instance (component or assembly - don't choose data types) or a drawing. 

You can set the instance constant at the component level, assembly level or project level.

To open a view, use the call Display_Open_window_interface.open()

Further, to close the view use the call Display_Open_window_interface.close()

Last, the interface ignores two .open calls in a row. So you don't open the same window twice.

You can only locate a component with the Display_Open_window_interface in a device with a display. Examples are the PD 688 or the PD 955 COPP PC with display.

You can use a timer to keep the window open - for a time that you set- before it closes again.

NB: You can close the window “manually” via the touch screen. In this case, the interface doesn't call a .close. So, the program can only gain back control with a .close call before a .open.

For that reason, we suggest that you call a .close before you a .open call.
