RTF代码中的插入号/选择位置 [英] Caret/Selection position within RTF code

问题描述

大家好，
我目前正在尝试使用粗体，上标等内容，以便在富文本框中格式化数据.

有谁知道如何在RTF代码中获得选择位置?
注意:我不是在TEXT中，而是在RTF中的位置.

例如，假设插入符号的位置在单词sat
的"a"和"t"之间 文字:
我坐在在垫子上
RTF(大致):
我/b sat/b0在垫子上

选择位置将返回4，因为它在TEXT中排在第四位.
我想返回7，因为那是RTF代码中插入符号的位置.

仅供参考，我是因为我没有使用以下代码:

Hi guys,
I''m currently trying to use bolding, superscript etc in order to format data in a rich textbox.

Does anyone know how to get the selection position within the RTF code??
NB i DON''T mean within the TEXT, but rather where in the RTF.

e.g Say the caret position was between the ''a'' and the ''t'' in the the word sat
Text:
I sat on the mat
RTF (roughly):
I /b sat/b0 on the mat

Selection position would return 4 because it''s the fourth place in the TEXT.
I would want to have 7 returned, because that''s where the caret is in the RTF code.

FYI i reason I''m not using code like:

FontStyle style2Add = aRichTextBox.SelectionFont.Style ^ FontStyle.Bold;
aRichTextBox.SelectionFont = new Font(aRichTextBox.SelectionFont, style2Add | (aRichTextBox.SelectionFont.Style ^ FontStyle.Bold));

这是因为，如果您选择的字词结尾处的格式 tted 完全不同，那么它倾向于清除其他格式.当您突出显示很多文本(我已经尝试过)时，逐个字母地格式化单词(大约是每个字符的上述循环)太慢了.

那么，问题又来了:有人知道如何在RTF代码中获得选择位置吗?

谢谢！

is because it has a lovely tendency to wipe out other formatting if you have selected a word which is formatted differently at the end. Formatting words on a letter-by-letter basis (which roughly would be a loop of the above for each character) is simply too slow when you have a lot of text highlighted (i''ve tried it).

So, the question again: Does anyone know how to get the selection position within the RTF code??

Thanks!

推荐答案

您尝试使用SelectedRtf属性吗?
摘要:
获取或设置控件中当前选定的RTF格式的文本.
返回:
控件中选定的RTF文本.

Havge you tried the SelectedRtf property?
Summary:
Gets or sets the currently selected rich text format (RTF) formatted text in the control.
Returns:
The selected RTF text in the control.

Can you not work with that, rather then trying to find the position?

关于使用这种方法在光标位置插入标签的任何想法?
我可以使用richtextbox.selectedRTF属性更改字体，并输入标签，例如"//super"(上标)等，效果很好.

例如

Any ideas on inserting tags at the cursor position with such a method??

I can use the richtextbox.selectedRTF property to change the font, and input tags such as "//super " (superscript) and so on, which works great.

e.g.

"{\\rtf1\\ansi\\ansicpg1252\\deff0\\deflang5129{\\fonttbl{\\f0\\fnil\\fcharset0 Arial;}}\r\n\\uc1\\pard\\fs24 Some Selected Text!}\r\n"

*插入超级脚本标签*

*INSERT SUPERSCRIPT TAG*

"{\\rtf1\\ansi\\ansicpg1252\\deff0\\deflang5129{\\fonttbl{\\f0\\fnil\\fcharset0 Arial;}}\r\n\\uc1\\pard\\super\\fs24 Some Selected Text!}\r\n"

但是，如果没有突出显示文本，则无法在插入符号的位置插入格式，因为selectedRTF看起来像这样:

However, if no text is highlighted, I have no way of inserting formatting at the caret position, because the selectedRTF looks something like this:

"{\\rtf1\\ansi\\ansicpg1252\\deff0\\deflang5129\\uc1 }\r\n"

如果您按下上标"按钮，即使没有选择任何内容，您也希望能够键入上标.

在这里撕扯我的头发:s

if you pressed the ''superscript'' button, you''d expect to be able to type in superscript, even if nothing around was selected.
