Declaration

property ActivePageState: TWindowState read; write; default wsMinimized;

Property Value

Type	Default
TWindowState	wsMinimized

Remarks

Use this property to switch between available Navigation pane display modes:

Value	Description	Example
wsNormal	The control’s area is divided between the Navigation pane and the displayed document. The pane is aligned to the left border of the control filling it vertically. End-users can resize the Navigation pane by dragging its right border.
wsMinimized	The Navigation pane is displayed as a narrow vertical bar at the left control’s border. The pane shows no bookmarks in this mode. Clicking the Bookmark glyph expands the Navigation pane to the wsNormal state.
wsMaximized	The pane occupies the entire control’s area, overlapping the currently displayed document.

End-users can click the “Minimize/Restore” and “Maximize/Restore” buttons displayed by the Navigation pane to switch between its display modes:

Note

The Navigation pane is visible only if the PDF Viewer control displays a document with bookmarks and the Visible property is set to True.

The default ActivePageState property value is wsMinimized.
