Correct spacing of a text in QT Creator using QTextEdit

[gimv30]

I am trying to allign some text and show it via QTextEdit but I'm not sure how to do it properly .
I realized that the space in QT creator doesnt take as much as a normal character and I guess there's where I have problems because I can space it well in c/c++ using this:

snprintf(BufInterm1,100,"%-25s",BufferPPart); - %-25s

snprintf(BufInterm1,100,"%-25s",BufferPPart); - %-25s

To copy to clipboard, switch view to plain text mode 

However, when I send it to QT, it's not displayed proper. Any idea how I can space it well ?

This is how I'm showing it:

ui->MersulText->setText(MersSosiri);

ui->MersulText->setText(MersSosiri);

To copy to clipboard, switch view to plain text mode 

I've tried different fonts but none work unfortunately

LAST EDIT: Fixed it, it can be closed
