TreeView controls


When HasButtons is enabled, PowerBuilder displays + and - buttons next to parent items. The buttons indicate whether an item is expanded (-) or collapsed (+).


In a painter

To enable the display of buttons:

  • Select the HasButtons check box on the General page of the control's Properties view.

In scripts

The HasButtons property takes a boolean value. The following line specifies that PowerBuilder will display + and - buttons in a TreeView:

tv_1.HasButtons = TRUE
