[转载]EasySize宏在CFormView类中的使用

转:http://happyboy200032.blog.163.com/blog/static/46903113201242101247838/

由于在CFormView类中的初始化和CDialog类的初始化的不同（CFormView类初始化时相应的控件好像还没创建），因此不能简 单的在onsize函数中添加 UPDATE_EASYSIZE宏，所以在onsize中需要判断是否是第一次调用onsize函数，然后再做相应的处理，好了，话不多说，上代码：

 

void CMyView::OnSize(UINT nType, int cx, int cy)

{

      CFormView::OnSize(nType, cx, cy);

 

      if (m_bFirst && IsWindowVisible()&& GetWindow(GW_CHILD)!=NULL)

      {

             INIT_EASYSIZE;

             m_bFirst = FALSE;

             SetScrollSizes(MM_TEXT,CSize(0,0));

             UPDATE_EASYSIZE;

      }else if (!m_bFirst){

             SetScrollSizes(MM_TEXT,CSize(0,0));

             UPDATE_EASYSIZE;

      }

}

 

然 后 Ali Rafiee说，还要将easysize.h文件中最后一句 GetDlgItem(id)->MoveWindow(left,top,right-left,bottom-top,FALSE);/改成 GetDlgItem(id)->MoveWindow(left,top,right-left,bottom-top,TRUE);/ ，其他地方不变，这样，在CFormView类中使用easysize也可以正常的展示了。

 

原文：

I found a solution for the form view problem (and it's working great for me). The problem is that when OnInitalUpdate gets called the form (eventhough created) has a width and height of zero. So what I did was put an if statment in the OnSize where the first time around I call INIT_EASYSIZE, and from there on I call UPDATE_EASYSIZE. Also you have to call SetScrollSizes(MM_TEXT,0,0) in order to get rid of the scrollbars.

 

void CMyView::OnSize(UINT nType, int cx, int cy)

{

    CFormView::OnSize(nType, cx, cy);

 

    if (m_bFirst && IsWindowVisible()&& GetWindow(GW_CHILD)!=NULL)

    {

        INIT_EASYSIZE;

        m_bFirst = FALSE;

        SetScrollSizes(MM_TEXT,CSize(0,0));

        UPDATE_EASYSIZE;

    }else if (!m_bFirst){

        SetScrollSizes(MM_TEXT,CSize(0,0));

        UPDATE_EASYSIZE;

    }

}

 

Hope this helps.

I forgot to add that I also had to change the last line in Easysize.h from 

 GetDlgItem(id)->MoveWindow(left,top,right-left,bottom-top,FALSE);\

 to 

 GetDlgItem(id)->MoveWindow(left,top,right-left,bottom-top,TRUE);\

 So that the controls get redrawn correctly during the sizing
