Detailed Description
The QTextInlineObject class represents an inline object in a QAbstractTextDocumentLayout and its implementations.
Normally, you do not need to create a QTextInlineObject. It is used by QAbstractTextDocumentLayout to handle inline objects when implementing a custom layout.
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 textDirection(). Its position in the text layout is given by textPosition(), and its format is given by format().
Member Function Documentation
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 descent 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.
