NX二次开发-通过获取窗口句柄方式来设置类型过滤器EnumChildWindows

Posted 2021-09-07 阿飞的技术博客

• 版本

NX9+VS2012

 

• 说明

我们可以通过获得NX的父项窗口句柄来遍历下面的子项窗口句柄。

然后对每个句柄单独发送消息，来执行操作。

获得NX窗口句柄用这个函数UF_UI_get_default_parent()

遍历子窗口用这个函数EnumChildWindows

 

下面的这个例子是遍历类型过滤器句柄，然后模拟鼠标点击，选择下拉类型。

但是这个例子还不够完善，还有很多问题，后续在花点时间不断完善。

本来想得到句柄后，直接用SetWindowText去设置过滤器当前显示的内容，结果还不行。不起作用。

后来又想用SendMessage发送消息，设置显示内容WM_SETTEXT，还是不行，设置下拉枚举第几个也不行。

几种方法试了都不行，才选择了用鼠标模拟点击去做的。
