Detailed Description

Scrollable list of items with keyboard and mouse navigation.

Supports single selection via keyboard (Up/Down/PageUp/PageDown/Home/End) and mouse (click to select, double-click to activate). Mouse wheel and scrollbar interaction scroll the viewport independently of the selection. The Enter key activates the current item via the itemActivated signal.

Thread Safety: Thread-affine — see TuiWidget.

void promeki::TuiListView::ensureVisible ( int index )

Parameters

index The item index to make visible.

Scrolls the viewport by the given number of items.
