panel.

<p>Secondly, it formats its elements differently. The actual controls

are placed one below the other with a title bar above each control.

Clicking on the title bar expands or collapses the control. When there

is not enough space then scroll bars are shown.</p>

<p>To avoid flickering when painting the sub tool panel the background
|

is made transparent and painting it is done by this class. While

layouting its children it remembers the gaps between children and stores
|
|
them in maStripeList. In Paint() those gaps as well as the border
|
|
arround all children are painted in the background color.</p>
