推荐答案

Hello Devadutta，

当焦点位于RichTextBox控件上时，请按住Control键并使用鼠标上的滚动按钮.这样，您就可以放大和缩小，使文本随心所欲地变大或变小.

哦，不:我再读一次也太肤浅了.下面的解决方案是
WinForm而不是MFC的请求. (对我感到羞耻)

开始修改

如果您想在代码方面做到明智:

Hello Devadutta,

when the focus is on the RichTextBox control hold down the control key and use the scroll button on your mouse. This way you''ll be able to zoom in and out, making the text bigger or smaller as you wish.

Oh no: I''ve been reading too superficially again. Solution below is
for WinForm and not MFC as requested. (Shame on me)

Start of modification

If you''d like to do it code wise:

public partial class Form1 : Form
{
    public Form1()
    {
        InitializeComponent();
    }

    private void trackBar1_Scroll(object sender, EventArgs e)
    {
        float factor = (float)trackBar1.Value / 10;
        richTextBox1.ZoomFactor = factor;
    }
}

该窗体包含一个TrackBar和RichTextBox控件. TrackBar的最大值为40，最小值为1.通过Scroll事件处理程序中的计算，缩放系数实际上设置为从十分之一(0.1)到4.0的任何值.当然，您可以根据需要选择自己的值；).

修改结束

问候

The form contains a TrackBar and a RichTextBox control. The TrackBar has a Maximum of 40 and a Minimum of 1. Via the calculation in the Scroll event handler the zoom factor is effectively set to anything from one thenth (0.1) up to 4.0. Of course you can choose your own values as you please ;) .

End of Modification
