Get QLineEdit Text Fields

Question

How to get text fields for QLineEdit?

Notice the red lines in the screenshot that the fields that interest me are:

I tried qDebug() << ui->lineEdit->textMargins(); for the edit window from the screen, but printed QMargins(0, 0, 0, 0) , although the edit field has fields.

Answer 1

Check out the QLineEdit drawing event . As you can see, many things affect this.

Besides textMargins there are things that can influence the values ​​you are looking for.

1. used style (see line 1942)
2. and font properties - see QFontMetrics :: ascent and QFontMetrics :: descent

The style value is the most important, and you should find a way to get that value (probably a subclass is needed).
