Modifying InfLineLabel

[Csaba Benkó]

Hey guys,

i'm trying to modify the InfLineLabel class so that its x-position is fixed and its y-position is relative to the viewbox, just like when a normal InflineLabel is attached to a vertical InfiniteLine. If it's parent isn't a InfLine, it behaves like it's attached to a horizontal one, meaning it's locked to the y-position instead to the x and it can be moved along the x-axis instead of the y. I simply cannot find at all where or how the alignment of the line is checked. 

The changes are really rudimentary, but i attached the modified class. I'd really appreciate if someone could help me out.

In __init__:

 self.setAnchor(self.anchors[1]) #set to left of line

# self.setAnchor(self.anchors[0]) #set to right of line

Now just change updatePosition as follows:

    def updatePosition(self):

        # update text position to relative view location along line

        self._endpoints = (None, None)

        pt1, pt2 = self.getEndpoints()

        if pt1 is None:

            return

        pt = pt2 * self.orthoPos + pt1 * (1-self.orthoPos)

        self.setPos(pt)

        

        #This flips the text label automatically to the left or right of the line when the 

        #line transverses the middle of the viewbox

        # update anchor to keep text visible as it nears the view box edge

        # vr = self.line.viewRect()

        # if vr is not None:

        #     logger.debug(vr.center().y())

        #     self.setAnchor(self.anchors[0 if vr.center().y() < 0 else 1])
