UMLWidget * Widget_Utils::findWidget	(	Uml::ID::Type	id,
		const UMLWidgetList &	widgets,
		const MessageWidgetList *	messages
	)

Find the widget identified by the given ID in the given widget or message list.

Parameters

id	The unique ID to find.
widgets	The UMLWidgetList to search in.
messages	Optional pointer to a MessageWidgetList to search in.

Definition at line 41 of file widget_utils.cpp.

bool Widget_Utils::hasSmallerX	(	const UMLWidget *	widget1,
		const UMLWidget *	widget2
	)

Returns true if the first widget's X is smaller than second's.

Used for sorting the UMLWidgetList.

Parameters

widget1	The widget to compare.
widget2	The widget to compare with.

Definition at line 536 of file widget_utils.cpp.

bool Widget_Utils::hasSmallerY	(	const UMLWidget *	widget1,
		const UMLWidget *	widget2
	)

Returns true if the first widget's Y is smaller than second's.

Used for sorting the UMLWidgetList.

Parameters

widget1	The widget to compare.
widget2	The widget to compare with.

Definition at line 547 of file widget_utils.cpp.

bool Widget_Utils::loadBrushFromXMI	(	QDomElement &	qElement,
		QBrush &	brush
	)

Extracts the QBrush properties into brush from the XMI xml element qElement.

Parameters

qElement	The dom element from which the xmi info should be extracted.
brush	The QBrush object into which brush details should be read into.

Definition at line 455 of file widget_utils.cpp.

bool Widget_Utils::loadGradientFromXMI	(	QDomElement &	gradientElement,
		QGradient *&	gradient
	)

Loads gradient from xmi.

The gradient pointer should be null and the new gradient object will be created inside this method. The gradient should later be deleted externally.

Parameters

qElement	The dom element from which gradient should be loaded.
gradient	The pointer to gradient into which the gradient should be loaded. (Allocated inside this method)

Returns

True or false based on success or failure of this method.

Definition at line 334 of file widget_utils.cpp.

bool Widget_Utils::loadPixmapFromXMI	(	QDomElement &	pixEle,
		QPixmap &	pixmap
	)

Loads pixmap from xmi.

Parameters

qElement	The dom element from which pixmap should be loaded.
pixmap	The pixmap into which the image should be loaded.

Returns

True or false based on success or failure of this method.

Definition at line 272 of file widget_utils.cpp.

QString Widget_Utils::pointToString

(

const QPointF &

point

)

Draws an arrow head with the given painter, with the arrow sharp point at headPos.

Parameters

painter	The painter with which this arrow should be drawn.
headPos	The position where the head of the arrow should lie.
arrowSize	This indicates the size of the arrow head.
arrowType	This indicates direction of arrow as in LeftArrow, RightArrow..
solid	If true, a solid head is drawn. Otherwise 2 lines are drawn. Draws a rounded rect rounded at specified corners.
painter	The painter with which this round rect should be drawn.
rect	The rectangle to be drawn.
xRadius	The x radius of rounded corner.
yRadius	The y radius of rounded corner.
corners	The corners to be rounded. Converts a point to a comma separated string i.e "x,y"
