Member Function Documentation

virtual void canvascv::CompoundShape::draw ( cv::Mat & canvas )

protectedvirtual

Parameters

canvas

Implements canvascv::Shape.

Reimplemented in canvascv::Line, canvascv::LineCrossing, canvascv::Polygon, canvascv::Rectangle, and canvascv::Arrow.

virtual std::shared_ptr<Shape> canvascv::CompoundShape::getShape ( int id )

virtual

Get internal shapes, which Canvas doesn't know of.

Parameters

id

Returns: internal sub shape with requested id

Reimplemented from canvascv::Shape.

virtual bool canvascv::CompoundShape::keyPressed ( int & key )

protectedvirtual

Parameters

key	was pressed. You must set it to -1 if you consumed it.

Returns: true if we want to stay in focus and false otherwise

Reimplemented from canvascv::Shape.

Reimplemented in canvascv::Line, canvascv::Polygon, and canvascv::Rectangle.

virtual bool canvascv::CompoundShape::mouseMoved ( const cv::Point & pos )

protectedvirtual

Was a mouse moved over this shape?
If shape is during edit, then these are the mouse position.
Parameters

pos

Returns
true if a mouse moved over this shape, or it is during edit. false otherwise.

Implements canvascv::Shape.

Reimplemented in canvascv::Line, canvascv::Polygon, and canvascv::Rectangle.
