QT Designer - Slider with decimal steps
-
Hi all, new here. I am starting with Qt5 and building a control interface based on sliders, doublespinbox and LCDs
I cannot find a way in QT Designer to set a slider with decimal steps, I will be working with temp and pressure so decimals are mandatory.
Double spinbox works for that but I would like to have decimals also for sliders. Is this feasible from QT Designer? currently using v 5.15.2
Thanks in advance

Hi and welcome to the forums
Im afraid the slider cannot do decimal steps so you are most likely looking at a custom slider
to make that happen.
I could not find an example of decimal steps, only using doubles for its value but could be a starting point

At the end I found easier to keep the SLider generated by QT Designer and connect to a simple function scaling the values, like this:
tempSlider = temperature slider
tempSpinBox= double Spin Box for temperaturefrom slider to spinbox
self.tempSlider.valueChanged['int'].connect(self.changeTspinBoxValue)
def changeTspinBoxValue(self,val):
val = float(val / 10)
print(val)
self.tempSpinBox.setValue(val)and viceversa for spinbox to slider
self.tempSpinBox.valueChanged['double'].connect(self.changeTsliderValue)
def changeTspinBoxValue(self,val):
val = float(val / 10)
print(val)
self.tempSpinBox.setValue(val)Thanks
