How to get QTextEdit Text minimum Height ? I Want use ScrollBar..

Pada_

Hello. I use windows 8.1 64bit and linux 64bit,
I am using Qt Version 5.4.

The text is written in QTextEdit and you can resize this TextEdit widget.

When you resize the TextEdit widget while text is being written, a scrollbar is automatically created when the size is reduced.

I want to know the minimum size of the text in the TextEdit Widget without scrollbars, and I can't make the widget smaller than its size.

How can I find the minimum size without scrollbars?

Example 1)

ab
c

When written as above, the screen

ab
c

This is the minimum size at which no scrollbars appear.

Example 2)

abc

When I wrote as above, on a screen

abc

This is the minimum size at which no scrollbars appear.

Thank you.

Hi,

QFontMetrics::boundingRect seems to be what you are looking for.

Even though each font has a different color and bold font size, can I solve it with plain text? It doesn't seem to work.

What exactly does not work ?
Note that Qt 5.4 is more than outdated, you should consider updating to a recent version.

I want to do it like the above article.

Setting toPlainText returns a smaller size than desired
The scroll bar is still visible.
