Detailed Description

Mixin representing the UI for drawing a contour in the 2D window. It relies on the mixed subtype calling drawMouse*
methods when mouse events are caught and reacting appropriately when drawing occurs (ie. when those methods return
True). When drawing is done the final contour is in self.contour and can then be accessed by the mixed subtype.
The method fillContourFig() must be called whenever the view is updated (ie. updateView() as in BaseCamera2DWidget).

Constructor & Destructor Documentation

__init__()

def __init__	(		self,
			numNodes,
			matname = 'newContour',
			drawcolor = color(1,0,0)
	)

Member Function Documentation

drawMouseDrag()

def drawMouseDrag	(		self,
			e,
			dx,
			dy
	)

Add points to the contour when the mouse is dragged with position delta (dx,dy). This will interpolate over
large distances to (mostly) ensure a uniform distribution of points along the drawn contour. Returns True
if the contour was drawn, False otherwise.

Here is the call graph for this function:

Here is the caller graph for this function:

drawMousePress()

def drawMousePress	(		self,
			e
	)

Start drawing the contour, returns True if drawing was enabled and the contour started, False otherwise.

Here is the call graph for this function:

Here is the caller graph for this function:

drawMouseRelease()

def drawMouseRelease	(		self,
			e
	)

Finish drawing the contour, returns True if the drawing was enabled and enough contour points were present
to form a correct contour, False otherwise. The resulting contour is stored in self.contour if True is returned.

Here is the caller graph for this function:

fillContourFig()

Fills the figure representing the drawn contour with lines so that it is visible on screen while drawing.
