Detailed Description

The QTextFrameFormat class provides formatting information for frames in a QTextDocument.

A text frame groups together one or more blocks of text, providing a layer of structure larger than the paragraph. The format of a frame specifies how it is rendered and positioned on the screen. It does not directly specify the behavior of the text formatting within, but provides constraints on the layout of its children.

The frame format defines the width() and height() of the frame on the screen. Each frame can have a border() that surrounds its contents with a rectangular box. The border is surrounded by a margin() around the frame, and the contents of the frame are kept separate from the border by the frame's padding(). This scheme is similar to the box model used by Cascading Style Sheets for HTML pages.

The position() of a frame is set using setPosition() and determines how it is located relative to the surrounding text.

The validity of a QTextFrameFormat object can be determined with the isValid() function.

See also setBottomMargin().

QTextLength QTextFrameFormat::height () const

See also setHeight().

bool QTextFrameFormat::isValid () const

Returns true if the format description is valid; otherwise returns false.

qreal QTextFrameFormat::leftMargin () const

Returns the width of the frame's left margin in pixels.

This function was introduced in Qt 4.3.

See also setLeftMargin().

qreal QTextFrameFormat::margin () const

Returns the width of the frame's external margin in pixels.

See also setMargin().

qreal QTextFrameFormat::padding () const

Returns the width of the frame's internal padding in pixels.

See also setPadding().

PageBreakFlags QTextFrameFormat::pageBreakPolicy () const

Returns the currently set page break policy for the frame/table. The default is QTextFormat::PageBreak_Auto.

This function was introduced in Qt 4.2.

See also setPageBreakPolicy().

Position QTextFrameFormat::position () const

Returns the positioning policy for frames with this frame format.

See also setPosition().

Returns the width of the frame's right margin in pixels.

This function was introduced in Qt 4.3.

See also setRightMargin().

void QTextFrameFormat::setBorder ( qreal width )

Sets the width (in pixels) of the frame's border.

See also border().

void QTextFrameFormat::setBorderBrush ( const QBrush & brush )

Sets the brush used for the frame's border.

This function was introduced in Qt 4.3.

See also borderBrush().

void QTextFrameFormat::setBorderStyle ( BorderStyle style )

Sets the style of the frame's border.

This function was introduced in Qt 4.3.

See also borderStyle().

void QTextFrameFormat::setBottomMargin ( qreal margin )
