		QWidget *	parent = `NULL`
	)

Constructor.

Parameters

parent	the widgets parent
length	the minimal number of characters visible.

Member Function Documentation

◆ addAdditionalWidth()

void WScaleLabel::addAdditionalWidth ( int margin )

virtual

Set this to reserve extra space for a margin.

Parameters

margin the margin to keep in mind for size calculations

◆ calculateSize()

size_t WScaleLabel::calculateSize ( size_t chars ) const

virtual

Calculate the size that is needed for the given number of chars.

Parameters

chars number of chars

Returns: the size in pixels
