size=2>本书中许多范例应用程序允许使用者重新设定主视窗的大小。当然，重新设定主视窗大小会导致所有的子控制项被重新配置或重设大小。CUILayout
C++ 类别列于列表B-4中，它封装了所有子控制项的重新配置与重设大小的逻辑。</FONT></P>
<P><FONT style="LINE-HEIGHT: 25px" face=arial color=#000000
size=2>每一个应用程序支援一个重设大小的主视窗，它们将会建立一个CUILayout物件。在该视窗的Dlg_OnInitDialog函数中，CUILayout物件的Initialize方法被呼叫去设定父视窗的handle和视窗的最小宽度与高度。然后CUILayout物件的AnchorControl或AnchorControls方法会被重覆地呼叫，以识别每一个子控制项视窗以及该控制项应如何依据父视窗而被固定。</FONT></P>
<P><FONT style="LINE-HEIGHT: 25px" face=arial color=#000000
size=2>当主视窗执行了它的Dlg_OnSize函数时，它只需去呼叫CUILayout物件的AdjustControls方法，传递主视窗之客户区（Client
area）的宽度及高度给它即可。为了保持它与父视窗的的相对位置，AdjustControls方法将会自动地重新配置及重设所有子控制项大小。</FONT></P>
<P><FONT style="LINE-HEIGHT: 25px" face=arial color=#000000
size=2>当主视窗执行了Dlg_OnGetMinMaxInfo函数时，它需要去呼叫CUILayout物件的HandleMinMax方法。此方法设定了MINMAXINFO结构的成员，让使用者不会因为将视窗缩得太小而遮住了任何的子控制项。</FONT></P>
