问题描述
我有一个具有以下代码的按钮:
I have a button which has this code:
fontsize = richTextBox1.Font.Size;
fontsize++;
richTextBox1.SelectionFont = new Font(richTextBox1.Font.Name, fontsize, richTextBox1.Font.Style, richTextBox1.Font.Unit);
顺便说一下，fontsize是一个浮点数:
The fontsize is a float by the way:
static float fontsize = 9F; // declared at the start of program
基本上，它会将富文本框选择的字体设置为1大.但这不适用于SelectionFont.
它可以与richTextBox1.Font = new Font ...一起很好地工作.每次将只保持1上升，但是使用SelectionFont时，它将停止在10处并且不会上升.如果我使用另一个按钮减小SelectionFont的大小，它将不会低于8，并且会跳过9.
我使用SelectionFont怎么做才能使它像这样?我只希望fontsize可以上下移动，就像MS Word中的按钮一样.
请帮忙=)
Basically it sets the rich text box selected font 1 size bigger. But it doesn''t work with SelectionFont.
It works fine with richTextBox1.Font = new Font .... This will just keep going up 1 every time but with SelectionFont it stops at 10 and won''t go higher. And if I use another button to lower the SelectionFont size it won''t go below 8 and it skips out 9.
What am I doing wrong with SelectionFont to make it like this? I just want the fontsize to go up and down, much like that of the buttons in MS Word.
Help please =)
推荐答案
fontsize = richTextBox1.SelectionFont.Size + 1;
Font oldFont = RTB.SelectionFont;
Font newSize = new Font(oldFont.FontFamily.Name, FontSizeUD.Value, oldFont.Style);
RTB.SelectionFont = newSize;
