Detailed Description

The QTextInlineObject class represents an inline object in a QTextLayout.

This class is only used if the text layout is used to lay out parts of a QTextDocument.

The inline object has various attributes that can be set, for example using, setWidth(), setAscent(), and setDescent(). The rectangle it occupies is given by rect(), and its direction by isRightToLeft(). Its position in the text layout is given by at(), and its format is given by format().

Member Function Documentation

QTextInlineObject::QTextInlineObject ( int i, QTextEngine * e )

Creates a new inline object for the item at position i in the text engine e.

qreal QTextInlineObject::ascent () const

Returns the inline object's ascent.

See also setAscent(), descent(), width(), and rect().

qreal QTextInlineObject::descent () const

Returns the inline object's descent.

See also setDescent(), ascent(), width(), and rect().

QTextFormat QTextInlineObject::format () const

Returns format of the inline object within the text layout.

int QTextInlineObject::formatIndex () const

Returns an integer describing the format of the inline object within the text layout.

qreal QTextInlineObject::height () const

Returns the inline object's total height. This is equal to ascent() + descent() + 1.

See also ascent(), descent(), width(), and rect().

bool QTextInlineObject::isValid () const

Returns true if this inline object is valid; otherwise returns false.

QRectF QTextInlineObject::rect () const

Returns the inline object's rectangle.

See also ascent(), descent(), and width().

void QTextInlineObject::setAscent ( qreal a )

Sets the inline object's ascent to a.

See also ascent(), setDescent(), width(), and rect().

void QTextInlineObject::setDescent ( qreal d )

Sets the inline object's decent to d.

See also descent(), setAscent(), width(), and rect().

void QTextInlineObject::setWidth ( qreal w )

Sets the inline object's width to w.

See also width(), ascent(), descent(), and rect().

Qt::LayoutDirection QTextInlineObject::textDirection () const

Returns if the object should be laid out right-to-left or left-to-right.

int QTextInlineObject::textPosition () const

The position of the inline object within the text layout.

qreal QTextInlineObject::width () const

Returns the inline object's width.

See also setWidth(), ascent(), descent(), and rect().
