Visible Layers List
|
The tab layers that will be visible at Runtime. This property enables you to dynamically show, hide or reorder the tabs.
The order that you list them here will also be the order of the layers of the Tab control. If the layer list is empty, all the tabs will be shown.
The tab variable will get the value according to the layer number as defined in the Items List and the tab caption will be according to the Display List.
For example:
In this case, the tab will include two tabs with caption of Tab3 and Tab2.
Pressing the first tab (with caption of Tab3) will set the Tab's variable with the value of C.
Any controls that were attached to the 3rd tab (at Studio) will be shown.
If the tab variable is updated to a layer that is not visible, then no layer will be selected.
Since version: 1.5
