QUESTION
Trying to make a very simple node editor in Qt Quick.
The most tricky part seems to be the Connection
item, which has to track the two absolute positions of the source and destination IOPort
s.
The following code works fine, except that the bindings are not evaluated (or are evaluated in the wrong order) at startup, resulting in the connection line to be in the wrong position at startup:
which is then adjusted to the correct position as soon as either node is moved:
I thought about adding:

Your Connection
root
's start
and end
properties are missing a "forced" dependency on that same object's x
and y
For some reason you decided to not only to set the coordinates for path's points but also move the whole Connection
element itself. So if root
's x
and y
happen to update after start
and end
did, the latter still contain relative coordinates of the point when x
and y
were still default (probably 0,0
) and thus the line becomes displaced by x,y
pixels.
Try changing them this way (I also removed dependencies you shouldn't need):
