 Posted: Thu Oct 28, 2010 12:26 am Post subject: Which line textbox.selectedText() is on |
 |
|
Greetings.
Imagine the following scenario...
I have a textbox that opens with a list of emails. Each email is followed with a space " " and then a number. Something like this:
and so on. I have this function:
| Code: |
protected void PreviousVendor_doubleclick(Object sender, EventArgs ea)
{
//msgBox(PMAddress.selectedText());
char[][] s = std.string.split(PMAddress.selectedText()," ");
vEmail.text = std.string.strip(s[0]);
EmailForm.close();
}
|
which captures the email address when I double click on the email. The problem is when an email has a - on the email. Say,
jose@jose-some.info
What happens is that selectedText() just grabs jose@jose and ignores "-some.info". I know this is probably something to do with the way a continuous word is defined. In other words, how one defines a white space. - is probably a white space. The question is, how can I always grab the full email? The full email is always followed by a space. Is there a way for me to know which one is the line that I double click on?
thanks,
jose |

Here's how I get the line the user clicked in a text box.
| Code: | auto pt = myTextBox.pointToClient(Cursor.position);
auto charidx = myTextBox.getCharIndexFromPosition(pt);
auto line0idx = myTextBox.getLineFromCharIndex(charidx); // 0 based.
if(line0idx >= 0)
{
auto lines = myTextBox.lines;
if(line0idx < lines.length)
{
auto userLine = lines[line0idx]; |
