Properties

Detailed Description

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

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

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

MyItem {
    text: textMetrics.elidedText
}

See also QFontMetricsF and FontMetrics.

Property Documentation

advanceWidth : real [read-only]

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

See also QFontMetricsF::horizontalAdvance().


boundingRect : rect [read-only]

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

See also QFontMetricsF::boundingRect() and tightBoundingRect.


elide : enumeration

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

ConstantDescription
Qt::ElideNoneNo eliding; this is the default value.
Qt::ElideLeftFor example: "...World"
Qt::ElideMiddleFor example: "He...ld"
Qt::ElideRightFor example: "Hello..."

See also elideWidth and QFontMetrics::elidedText.


elideWidth : real

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

See also elide and QFontMetrics::elidedText.


elidedText : string [read-only]

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

See also QFontMetricsF::elidedText().


font : font

This property holds the font used for the metrics calculations.


height : real [read-only]

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

textMetrics.boundingRect.height

See also boundingRect.


renderType : enumeration [since 6.3]

Override the default rendering type for this component.

Supported render types are:

ConstantDescription
TextEdit.QtRenderingText is rendered using a scalable distance field for each glyph.
TextEdit.NativeRenderingText is rendered using a platform-specific technique.

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

This property was introduced in Qt 6.3.

See also Text.renderType.


text : string

This property holds the text used for the metrics calculations.


tightBoundingRect : rect [read-only]

This property holds a tight bounding rectangle around the characters in the string specified by text.

See also QFontMetricsF::tightBoundingRect() and boundingRect.


width : real [read-only]

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

textMetrics.boundingRect.width

See also boundingRect.
