BBjTabCtrl::isCloseableAt

Description

In BBj 16.0 and higher, this method returns whether a specific BBjTabCtrl tab currently includes a close button.

Syntax

Return Value	Method
boolean	isCloseableAt(int `index`)

Parameters

Variable	Description
index	Specifies the 0-based index of tab.

Return Value

Returns whether the tab currently shows a close button (0 = No close button, 1 = Close button).

Remarks

Clicking the close button fires an ON_TAB_CLOSE_EVENT, which the program is free to honor or ignore. By default, the BBjTabCtrl does not show close buttons on tabs.
