My Issue/Question:

I want to create a SliderFloat, where the min and max values are set by other slider floats. Is this possible? Advisable? Is there a better way? I thought maybe just input the end min/max using input widgets but using sliders allow me to see the resulting effects on my scene in realtime.

So what I think I could do is something like this:

float minMin = 1.0;
float maxMin = 10.0;
float minValue = 1.0;
SliderFloat("MinValue", &minValue, minMin, maxMin, format = "%.3f");

float minMax = minValue;
float maxMax = minValue * 10.0;
float maxValue = maxMax;
SliderFloat("MinValue", &maxValue, v_min, v_max, format = "%.3f");

float endValue = minValue + (maxValue - minValue)/2.0;
SliderFloat("EndValue", &endValue, minValue, maxValue, format = "%.3f");

Minimal, Complete and Verifiable Example code:

// Here's some code anyone can copy and paste to reproduce your issue
ImGui::Begin("SliderSliderSlider");
float minMin = 1.0;
float maxMin = 10.0;
float minValue = 1.0;
SliderFloat("MinValue", &minValue, minMin, maxMin, format = "%.3f");

float minMax = minValue;
float maxMax = minValue * 10.0;
float maxValue = maxMax;
SliderFloat("MinValue", &maxValue, v_min, v_max, format = "%.3f");

float endValue = minValue + (maxValue - minValue)/2.0;
SliderFloat("EndValue", &endValue, minValue, maxValue, format = "%.3f");

ImGui::End();

Hello,

You seem to have answered your own question. I don't understand what else you are asking for? If that does what you want you can use that.

Is this possible?

Yes.

Advisable?

Depends what you want to do with them. Why not.

Is there a better way?

A better way to do what? Your code does exactly what you said you wanted to do.

Version 1.62

Note that this is an extremely old version (more than 6 years old) it is expected to be unsupported.

Thanks for the (very) fast reply. I guess the question really should have been "does this do what I want it to do".
