MFC应用程序中CScrollView的使用

发布于 2024-11-19 13:15:23 字数 699 浏览 0 评论 0原文

我正在为我们的应用程序使用 CSCrollView 窗口，其中我在视图中绘制了表格。我从 CSCrollView 派生了 CMYclass，但是当我上下滚动窗口时，我所拥有的任何内容都会被删除。我如何才能实现它......我需要执行与写字板处理图像和文本相同的活动。我想继续垂直滚动视图。直到页面结束。

这是代码片段：-

void CMyView::OnInitialUpdate()
{
     CSize sizeTotal;
     // TODO: calculate the total size of this view
     sizeTotal.cx = 450;
    sizeTotal.cy = 700;
    SetScrollSizes(MM_TEXT, sizeTotal);
} 

void CMyView::OnDraw(CDC* pDC)
{
    for(int i = 1;i<50;++i)
    {
        AddRow(pDC);
        TopPos = Height+TopPos;//  ![Outpu Window Image][1]
        nCountRow++;
    }
}

它只绘制了 18 行，但是当我向下滚动时，绘制的内容不再存在，并且滚动区域中也没有出现任何内容。

还有什么需要补充的吗？

I am using CSCrollView window for our Application in which i have table drawn in View.
I have derived the CMYclass from CSCrollView, But whenevr i am scrolling the window up and down whatever i have drwan is getting erased. How i can acheive it this... i need to perform same actvity like a Word Pad is doing with images and Text. I want to keep scroll the View Vertically. Till the page ends.

Here is the code snippet:-

void CMyView::OnInitialUpdate()
{
     CSize sizeTotal;
     // TODO: calculate the total size of this view
     sizeTotal.cx = 450;
    sizeTotal.cy = 700;
    SetScrollSizes(MM_TEXT, sizeTotal);
} 

void CMyView::OnDraw(CDC* pDC)
{
    for(int i = 1;i<50;++i)
    {
        AddRow(pDC);
        TopPos = Height+TopPos;//  ![Outpu Window Image][1]
        nCountRow++;
    }
}

it is only drawing 18 rows, but when iam scrolling down above drawn content is no more and also there is nothing coming up in scrolled area.

Is there anything more need to add?

Thanking for help
