Marmoset's Python->"onChange"

goekbenjamin · Mar 2019

when using "UISliderFloat->onChange"
how can i get the slider instance inside of that callable?

def changeit():
#hiw to get the slider?

myslider = mset.UISliderFloat()
myslider.onChange = changeit

------

or is it even possible to use parameter within that callable?

One option is to use a class, and to make myslider a member variable of that class. You can find a similar example of that in the Generate Primitives example in Toolbag, but here's an example:

import mset

class MyPlugin:
    window = mset.UIWindow("My Plugin")
    slider = None

    def sliderChangeCallback(self):
        print(self.slider.value)

    def render(self):
        self.window.clearElements()
        self.slider = mset.UISliderFloat(min=0.1, max=10, name="My New Slider")
        self.slider.onChange = lambda: self.sliderChangeCallback()
        self.window.addElement(self.slider)
        self.window.visible = True

    def __init__(self):
        self.render()

MyPlugin()
