详细描述

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
}

特性文档编制

advanceWidth : real

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.

另请参阅 QFontMetricsF::width() .

boundingRect : rect

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

另请参阅 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:

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

elideWidth : real

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

另请参阅 elide and QFontMetrics::elidedText .

elidedText : string

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

另请参阅 QFontMetricsF::elidedText() .

font : font

This property holds the font used for the metrics calculations.

height : real

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

text : string

This property holds the text used for the metrics calculations.

tightBoundingRect : rect

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

另请参阅 QFontMetricsF::tightBoundingRect() and boundingRect .

width : real

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
