QString size

[^NyAw^]

Hi,

How can I know the size in pixels will a QString be?
For example, a QString having "ERROR" as text, wich will the minimum size that I have to set to the QLabel to ensure that will be displayed?
The text showed into the QLabel will be modified but I know that "ERROR" is the max length word.

Thanks,

Well, you can calculate it with QFontMetrics, but there was no need if the label was in a layout.

If the label is in a layout it will be resized as I change the text, ok? So, I don't want it to be resized every time, I want to be the maximum text size.

Will take a look at QFontMetrics.

You break the layout; if exist for label.

• QFontMetrics::QFontMetrics ( const QFont & font )
• QFontMetrics::width ( const QString & text, int len = -1 )
• QFontMetrics::width ( QChar ch )

The above member of QFontMetrics help you.
