问题 Is there a way to set the cusror position in GWT RichTextArea. There is method setCusrorPosition() to do so in TextArea, but not in RichTextArea. Perhaps there is a native JavaScript (called from GWT) that could set the cursor position in the RichTextArea? 回答1: You are right RichTextArea is not providing the setSelectionRange method, but i have created one using the JSNI. Below is the method, public native void setSelectionRange(Element elem, int pos, int length) /*-{ try { var selection =

问题 I am using Rich Text object in my C# application. The only issue I am having is that when user pastes formated text from another app, it remains formated which I cannot have. Is there any way how to paste only string and ignore formatting? Thanks! 回答1: Assuming WinForms : try this : define a RichTextBox with a KeyDown event handler like this : Append-only example : private void richTextBox1_KeyDown(object sender, KeyEventArgs e) { if (e.Control && e.KeyCode == Keys.V) { richTextBox1.Text +=

问题 I'm new to WPF and I've found some similar questions but can't quite figure out the last part. I have a ViewModel with an ObservableCollection that contains error messages. I want to display these on the form AND allow the user to select and copy all or part of the messages. (In the past in WinForm apps I used a RichTextBox for this, but I can't figure out how to bind to one to the collection in WPF.) I got the look I was after with the following xaml, but there is no built-in way to select

问题 How can I make RichTextBox with no Margin, Border, Padding etc. ? In another words to display content in the same way as TextBlock does it ? I have tried this: <RichTextBox Margin="0" Padding="0" Grid.Row="0" BorderThickness="0" > <FlowDocument > <Paragraph>LLL</Paragraph> </FlowDocument> </RichTextBox> <TextBlock>LLL</TextBlock> But the result produces is still not what I want: There is still some space before document content (and also maybe after, on the top or bottom of the document...).

问题 I want to add a horizontal line to the RichTextBox as a delimiter of my text. I've found some examples of RTF code implementing a line and tried them in that way: rtbResFile.Rtf = @"{\rtf1{\pard some text.\par}{\pard \brdrb \brdrs \brdrw10 \brsp20 \par}{\pard \par}{\pard some other text.\par}}"; This way implements creating a blank paragraph with border, so that should looks like a line. However it doesn't show anything. Just a blank paragraph. Even if I try to implement it in the way include

问题 In C#, I have a RichTextBox, and I want to get the current line of the cursor. Every answer I've found says to use: int currentLine = richTextBox1.GetLineFromCharIndex(richTextBox1.SelectionStart); However, richTextBox1.SelectionStart only updates when you make changes to the text. If you move the cursor with the arrow keys, it does not update (I've verified this by printing SelectionStart as I move around). How do I get the current line of the cursor, in a way that tracks it even if you use

问题 After having done some research, I believe I am asking the same question as Remove richtextbox SelectionBackColor. I have encountered the same issue, but I believe the answers in that thread were insufficient as the question was not clearly explained.

I have a method that

问题 I am making a simple WinForms App and I wanted to allow the user to print the Text from RichTextBox. I followed MSDN link then.. And it works for a real printer (by real I mean that one I can touch:) ) But what if I want use some kind of PDF Printer? Then I must say it works when only one page is printed.
