使用动态布局使CMFCPropertySheet可调整大小 [英] Making a CMFCPropertySheet resizable with dynamic layouts

问题描述

我看到了这个问题，但是答案中的链接是不再有效.

I saw this question but the link in the answer is no longer valid.

我还找到了此.

I also found this which I tried and doesn't work and this.

我的任务应该很简单.我在CMFCPropertySheet上有几页，我想利用IDE中新的动态调整大小功能.因此，我设置了控件和控件的大小，但是当它们显示在工作表中时，就无法调整工作表/页面的大小.

My task should be simple. I have several pages on a CMFCPropertySheet and I want to take advantage of the new dynamic resizing features in the IDE. So I set the resizing of the controls and alas, when shown in a sheet there is no ability to resize the sheet/pages.

尝试上述资源失败.

为了进行测试，我刚刚创建了一个对话框应用程序，并添加了一个页面并将其分配给此工作表.

To test I just created a dialog application and added a page and assigned it to this sheet.

我只想支持使用属性表/页面进行动态调整大小.我缺少什么，实际上是否还需要任何这些代码?

I just want to support dynamic resizing with property sheets / pages. What am I missing and is any of this code actually needed any more?

在属性表窗口中添加WS_THICKFRAME样式.

Add WS_THICKFRAME style to the property sheet window.

int CALLBACK XmnPropSheetCallback(HWND hWnd, UINT message, LPARAM lParam)
{
    extern int CALLBACK AfxPropSheetCallback(HWND, UINT message, LPARAM lParam);
    // XMN: Call MFC's callback
    int nRes = AfxPropSheetCallback(hWnd, message, lParam);

    switch(message)
    {
    case PSCB_PRECREATE:
        // Set our own window styles
        ((LPDLGTEMPLATE)lParam)->style |= (DS_3DLOOK | DS_SETFONT
            | WS_THICKFRAME | WS_SYSMENU | WS_POPUP | WS_VISIBLE | WS_CAPTION);
        break;
    }
    return nRes;
}

INT_PTR CMyPropertySheet::DoModal()
{
    // Hook into property sheet creation code
    m_psh.dwFlags |= PSH_USECALLBACK;
    m_psh.pfnCallback = XmnPropSheetCallback;

    return CMFCPropertySheet::DoModal();
}

ps，原始文章有点旧.这将使用m_psh访问属性表的参数.

ps, the original article is a little old. This uses m_psh to access property sheet's parameters.

调整大小:

void CMyPropertySheet::OnSize(UINT nType, int cx, int cy)
{
    CPropertySheet::OnSize(nType, cx, cy);

    if(!GetActivePage()) return;
    if(!GetTabControl()) return;

    if(nType == SIZE_MINIMIZED)
        return;

    int dx = cx - save_rc.Width();
    int dy = cy - save_rc.Height();

    int count = 0;
    for(CWnd *child = GetWindow(GW_CHILD); child; child = child->GetWindow(GW_HWNDNEXT))
        count++;

    HDWP hDWP = ::BeginDeferWindowPos(count);

    for(CWnd *child = GetWindow(GW_CHILD); child; child = child->GetWindow(GW_HWNDNEXT))
    {
        bool move = false;
        //override***
        //If you add child controls manually, you want to move not resize
        //if(child == &static_control)
            //move = true;

        CRect r;
        child->GetWindowRect(&r);
        ScreenToClient(&r);

        if(move || child->SendMessage(WM_GETDLGCODE) & DLGC_BUTTON)
        {
            //move the main buttons and the child controls
            r.left += dx;
            r.top += dy;
            ::DeferWindowPos(hDWP, child->m_hWnd, 0, r.left, r.top, 0, 0,
                SWP_NOSIZE | SWP_NOZORDER | SWP_NOACTIVATE);
        }
        else
        {
            //this must be a child window, resize it
            r.right += dx;
            r.bottom += dy;
            ::DeferWindowPos(hDWP, child->m_hWnd, 0, 0, 0, r.Width(), r.Height(),
                SWP_NOMOVE | SWP_NOZORDER | SWP_NOACTIVATE);
        }
    }

    ::EndDeferWindowPos(hDWP);
    GetClientRect(&save_rc);
    Invalidate(TRUE);
}

BOOL CMyPropertySheet::OnInitDialog()
{
    CPropertySheet::OnInitDialog();
    GetClientRect(&save_rc);
    GetClientRect(&minimum_rc);
    return TRUE;
}
