WX-Python Speedmeter linked to slider

[CY CF]

Hi All,

I am making a slider linked to a speedmeter.
The needle initially takes the value of the slider.
But once modifying the value of slider it doesn't update anymore.

any advise?

cheers, Cam

You may be getting the problems because of the second bind, (within the
function).

You should not create a new instance of SpeedMeter every time you update
your slider. You should do this in your __init__ method:


self.speed = speed


And then, in the sliderUpdate method:

self.speed.SetSpeedValue(val)
