Class

The class of an outline control.

Control

Instance of the outline class. This control acts as a multiple-item list, with added functionality to display its items in a hierarchy and to display only selected subtrees of the hierarchy.

The outline can be navigated via the arrow keys and the PAGE UP/PAGE DOWN keys. Scrollbars appear along the length of the control when the list exceeds the size of the frame.

Adding an outline control to your form

Click the outline tool on the Component toolbar. Move the mouse cursor to the part of the form where you want to place the control, and click again. The control will appear with colored resizing handles.

Resizing and moving the control

Controls can only be resized and moved on forms during the design stage; the size and location of everything is fixed on a running form.

Resize the control by clicking the mouse cursor and dragging one of the handles to the new size-point. Release the mouse key when you are satisfied with the new size. Note: resizing the outline won't mean proportional changes in the size of the characters inside the list. Change the font property if you want to change the size of the actual characters displayed.

Move the control by clicking anywhere on it except a resizing handle and dragging it to a new location on the form. Release the mouse key when you are ready to place the control.
