How do I keep a QTextEdit widget from scrolling?
-
I need to place a text edit box of a certain size and I need to constrain the input to just the text that can be fit without scrolling. How do I achieve this?
I want to prevent this:
And have the input restricted to two lines that are the lines that fit on this size with this font size, like this:
So if the user keeps entering text, the box won't allow anything past the last character that fits on the second row
Any ideas?
Thanks!

Hi
Subclass QTextEdit and override keyPressed event.
There use QFontMetrics fm(this->font);
to check size of the text. if too big, ignore key
else add key to the text.I assume you want 3 lines if font is smaller so its not always 2 lines ?

Hello, thanks for helping!
No, I always want the same font size and only two lines. So, if the user writes enough to reach the end of the second line, then they can't input more text.
