Only <a href="#interesting">one of the + constructors</a> is of interest in most applications. +<p> TQSizePolicy contains two independent SizeType objects; one describes +the widgets's horizontal size policy, and the other describes its +vertical size policy. It also contains a flag to indicate whether the +height and width of its preferred size are related. +<p> The horizontal and vertical <a href="#SizeType-enum">SizeType</a>s are set in the usual constructor +and can be queried using a variety of functions. +<p> The <a href="#hasHeightForWidth">hasHeightForWidth</a>() flag indicates whether the widget's sizeHint() +is width-dependent (such as a word-wrapping label) or not. +<p> <p>See also <a href="#SizeType-enum">TQSizePolicy::SizeType</a>, <a href="appearance.html">Widget Appearance and Style</a>, and <a href="geomanagement.html">Layout Management</a>. + +<hr><h2>Member Type Documentation</h2> +<h3 class=fn><a name="ExpandData-enum"></a>TQSizePolicy::ExpandData</h3> + +<p> This enum type describes in which directions a widget can make use +of extra space.

The widget can be +shrunk any amount without detriment if other widgets need the +space (e.g. a separator line). +It cannot be larger than the size provided by sizeHint(). +<li><tt>TQSizePolicy::Preferred</tt> - The sizeHint() is best, but the widget can be +shrunk and still be useful.
