Constructor & Destructor Documentation

◆ QQuickTextMetrics()

QT_BEGIN_NAMESPACE QQuickTextMetrics::QQuickTextMetrics ( QObject * parent = nullptr )

explicit

\qmltype TextMetrics \instantiates QQuickTextMetrics \inqmlmodule QtQuick

Since: 5.4

Provides metrics for a given font and text.

TextMetrics calculates various properties of a given string of text for a particular font.

It provides a declarative API for the functions in \l QFontMetricsF which take arguments.

TextMetrics {
    id: textMetrics
    font.family: "Arial"
    elide: Text.ElideMiddle
    elideWidth: 100
    text: "Hello World"
}
 
MyItem {
    text: textMetrics.elidedText
}

◆ advanceWidth()

qreal QQuickTextMetrics::advanceWidth ( ) const

\qmlproperty real QtQuick::TextMetrics::advanceWidth

This property holds the advance in pixels of the characters in \l text. This is the distance from the position of the string to where the next string should be drawn.

◆ boundingRect()

QRectF QQuickTextMetrics::boundingRect ( ) const

\qmlproperty rect QtQuick::TextMetrics::boundingRect

This property holds the bounding rectangle of the characters in the string specified by \l text.

◆ elide()

Qt::TextElideMode QQuickTextMetrics::elide ( ) const

\qmlproperty enumeration QtQuick::TextMetrics::elide

This property holds the elide mode of the text. This determines the position in which the string is elided. The possible values are:

\value Qt::ElideNone No eliding; this is the default value. \value Qt::ElideLeft For example: "...World" \value Qt::ElideMiddle For example: "He...ld" \value Qt::ElideRight For example: "Hello..."
