Replacing a character in a QLineEdit text

[phil63]

Hi,

To simplify, I am using a QlineEdit line that contains : PRTU
I would like to replace the character 'R' by ' S'.
I tried :
line.text().replace('R','S') But it seems not to work.
I tried also:
text=""
if(line.text().contains('P') text=text+"P";
if (line.text().contains('R') text=text+"S"
if(line.text().contains('T') text=text+"T";
if(line.text().contains('U') text=text+"U";
line.setText(text);
but with no avail.
Could you help me, please

@
QString text = line.text();
text.replace("R", "S");
line.setText(text);
@

That should work.

Thank you for your reply.
As you advised I wrote:

QString text=line.text();
text.replace('R','S');
line.setText(text);

But the computer erases the charactere 'R' but put nothing instead.
What do I do wrong?
Thank you

I don't know. Code looks ok.

I found my mistake. I feel so stupid.
I made the changes in a constructor window that it not read at the beginning.
Well sorry for my stupidity.
Thanks for your help.

No problem, we all make mistakes in our apps :)
