Constructor & Destructor Documentation

◆ QQuickTextMetrics()

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

explicit

\qmltype TextMetrics \nativetype 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
}

Member Function Documentation

◆ 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.

See also: {QFontMetricsF::horizontalAdvance()}

Definition at line 147 of file qquicktextmetrics.cpp.

◆ 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.

See also: {QFontMetricsF::boundingRect()}, tightBoundingRect

Definition at line 162 of file qquicktextmetrics.cpp.

◆ 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..."

◆ elideChanged

void QQuickTextMetrics::elideChanged ( )

signal

◆ elidedText()

QString QQuickTextMetrics::elidedText ( ) const

\qmlproperty string QtQuick::TextMetrics::elidedText

This property holds an elided version of the string (i.e., a string with "..." in it) if the string \l text is wider than \l elideWidth. If the text is not wider than \l elideWidth, or \l elide is set to Qt::ElideNone, this property will be equal to the original string.

See also: {QFontMetricsF::elidedText()}

Definition at line 228 of file qquicktextmetrics.cpp.

◆ elideWidth()

qreal QQuickTextMetrics::elideWidth ( ) const

\qmlproperty real QtQuick::TextMetrics::elideWidth

This property holds the largest width the text can have (in pixels) before eliding will occur.

◆ elideWidthChanged

void QQuickTextMetrics::elideWidthChanged ( )

signal

signal

◆ height()

qreal QQuickTextMetrics::height ( ) const

\qmlproperty real QtQuick::TextMetrics::height

This property holds the height of the bounding rectangle of the characters in the string specified by \l text. It is equivalent to:

See also: boundingRect

Definition at line 198 of file qquicktextmetrics.cpp.

◆ metricsChanged

void QQuickTextMetrics::metricsChanged ( )

signal

◆ renderType()

QQuickText::RenderType QQuickTextMetrics::renderType ( ) const

\qmlproperty enumeration QtQuick::TextMetrics::renderType

Override the default rendering type for this component.

Supported render types are:

\value TextEdit.QtRendering Text is rendered using a scalable distance field for each glyph. \value TextEdit.NativeRendering Text is rendered using a platform-specific technique.

This should match the intended renderType where you draw the text.
