使用WINXGUI实现对话框布局控制 Splitter与 Pane控制

技术2022-05-11 105

在DELPHI和.NET的可视化设计中,利用Splitter和Panel可以实现控件的分组和布局控制,在WTL中提供了SplitterWindow对于对话框程序非常方便,而提供的CPaneContainer只能容纳一个控件,不能达到完全可视化的目的.WINXGUI提供了嵌入对话框设计的方式,本文的PANE控制就是基于WINXGUI实现的.实际上在WTL中也可以实现类似控制,但是用WINXGUI实现起来尤其方便,并且WINXGUI本身支持可视化设计. 参见http://winxgui.com

利用WINGUI的子类化技术,可以实现PANE控制,利用类似WINGUI设计的宏可以简化设计,利用WTL的SplitterWindow可以实现窗口分割控制.这样通过Spliter和Pane可以在VS6.0的对话框上直接进行设计,其中Splitter控制可以使用StaticText控件占位生成或直接动态生成,而Pane可以直接子类化StaticText控件.

一个应用例子: 需要使用WINXGUI.
