How to set font size of selected text in textbox?


Thanks!

推荐答案

您不能. TextBox有一个FontSize属性，这就是字体的大小.如果要更改所选文本的大小，我想您将不得不使用RichText控件.

You can''t. The TextBox has a FontSize property, and that''s what size the font is. If you want to change the size of selected text, I think you''re going to have to fiddle around with a RichText control.

如果您非常想使用TextBox. ..让我们说您的宗教禁止您使用任何带有Rich单词的东西，或者RichTextBox可能以某种方式亲自冒犯了您.

然后，您将不得不使用子类覆盖Paint事件，并根据需要绘制文本.当然，此方法会花费很多工作，并且已经在RichTextBox中为您完成了...但是，嘿，也许您真的不喜欢它.

If you badly want to use a TextBox...let''s say your religion bans you from using anything with the word Rich in it or maybe the RichTextBox has personally offended you in some way.

Then, you would have to overwrite the Paint event using subclassing and draw the text as you want it. Of course, this method would take a lot of work and is already done for you in the RichTextBox...but hey, maybe you just really don''t like it.
