tab-control

Arguments: dialog-item

Returns the value of the tab-control property of the argument. The value of the property is a list of two symbols, where the first symbol is the name of the tab-control that dialog-item is on, and the second is the name of the tab on this tab-control that dialog-item is on.

If you are interactively designing a dialog by using a form in the IDE, then dragging a widget completely into a tab will automatically assign the widget to the tab. But if you are creating the widgets programmatically, then you must do the assignment explicitly as shown in the example code on the page for the tab-control class, under the heading Adding widgets to tabs programmatically.

The value is nil if the control is not on a tab-control.

See the description of the tab-control class/control.
