CResizer

CResizer();

virtual void AddChild(CWnd* pWnd, Alignment corner, DWORD dwStyle);

virtual void AddChild(HWND hWnd, Alignment corner, DWORD dwStyle);

CRect GetMinRect() const;

CRect GetMaxRect() const;

Remarks

To use the CResizer class to manage the position of child windows, perform the following steps.

• Use Initialize to specify the parent window, along with the minimum and maximum permitted sizes.
• Use AddChild for each child window we wish to manage.
• Call HandleMessage from within DialogProc or WndProc to pass messages on to CResizer

The following code demonstrates how to initialize CResizer for a dialog.

BOOL CMyDialog::OnInitDialog()
{
    // Perform other tasks ...

    // Initialize dialog resizing
    m_Resizer.Initialize( this, CRect(0, 0, 300, 200) ); 
    m_Resizer.AddChild(m_RadioA,   topleft, 0);
    m_Resizer.AddChild(m_RadioB,   topleft, 0);
    m_Resizer.AddChild(m_RadioC,   topleft, 0);
    m_Resizer.AddChild(m_Button,   topleft, 0);
    m_Resizer.AddChild(m_CheckA,   bottomright, 0);
    m_Resizer.AddChild(m_CheckB,   bottomright, 0);
    m_Resizer.AddChild(m_CheckC,   bottomright, 0);
    m_Resizer.AddChild(m_RichEdit1, topright, RD_STRETCH_WIDTH);
    m_Resizer.AddChild(m_RichEdit2, bottomleft, RD_STRETCH_WIDTH| RD_STRETCH_HEIGHT);
	
    return true;
}

The following code shows how to add the CResizer message handling.

INT_PTR CMyDialog::DialogProc(UINT uMsg, WPARAM wParam, LPARAM lParam)
{
    // Pass resizing messages on to the resizer
    m_Resizer.HandleMessage(uMsg, wParam, lParam);

//  switch (uMsg)
//  {
//      Additional messages to be handled go here
//  }

    // Pass unhandled messages on to parent DialogProc
    return DialogProcDefault(uMsg, wParam, lParam);
}
