The way the title bar is displayed depends on the TitleBarType

the title string that shows whether the associated control is
visible (expanded) or not.
A title bar with TBT_WINDOW_TITLE is typically used only once as the
title bar of the whole task pane.
<p>The title bar shows three kinds of indicators: 1) Expansion is
displayed by two sets of two bitmaps, a triangle pointing to the right
resp. a minus in a square indicates that the control is collapsed, a
triangle pointing down resp. a plus in a square stands for an expanded
control. 2) Keyboard focus is indicated by a dotted rectangle. 3) An
underlined title string is a mouse over indicator for a
selectable/expandable control.</p>
