Member Function Documentation

void VideoPlayerTextObject::drawObject	(	QPainter *	painter,
		const QRectF &	rect,
		QTextDocument *	doc,
		int	posInDocument,
		const QTextFormat &	format
	)

Called when visible videoplayer object in the document needs to be redrawn.

Parameters:

	painter	QPainter used for drawing. Not used in this implementation
	rect	Area within the text document where the object needs to be drawn. Used when calculating the location of Video embedded in the text.
	doc	Pointer to document. Not used in this implementation.
	posInDocument	Position of the object in the document. Not used in this implementation.
	format	Format of the object. Stores pointer to struct VideoTextobjectListEntry as MyQTextBrowser::VideoPlayer property. This pointer can be used for accessing the related video player widget.

This function will update the geometry of the videoplayer object according to the rect parameter and position of the sliders of the text editor. The sliderpositions of the text editor are accessed by using pointer to struct VideoTextobjectListEntry type of object stored in format parameter and calling ((QTextEdit*)videoObjectPtr->WidgetPtr->parent())->verticalScrollBar()->sliderPosition()) where videoObjectPtr is pointer to struct VideoTextobjectListEntry.

QSizeF VideoPlayerTextObject::intrinsicSize	(	QTextDocument *	doc,
		int	posInDocument,
		const QTextFormat &	format
	)

Called when size of visible videoplayer object in the document needs to be calculated.

Parameters:

	doc	Pointer to document. Not used in this implementation.
	posInDocument	Position of embedded video in document counted as characters/textobjects from the beginning. Not used in this implementation.
	format	Format of the object. Stores pointer to struct VideoTextobjectListEntry as MyQTextBrowser::VideoPlayer property. This pointer can be used for accessing the related video player widget.

Returns:

Size of the video player widget embedded in the text document.
