Description
With Python 3.10, using a traitsui BoundsEditor for a Range fails:
from traits.api import *
from traitsui.api import *
from traitsui.qt4.extra.bounds_editor import BoundsEditor
class Test(HasTraits):
val = Range(0.3, 10.5)
_xmin = Float(5.0)
_xmax = Float(10.0)
view = View(
UItem(
'val',
editor=BoundsEditor(
low_name='_xmin',
high_name='_xmax',
format='%.2f')
)
)
Test().configure_traits()Traceback (most recent call last):
File ".../lib/python3.10/site-packages/traitsui/qt4/extra/range_slider.py", line 81, in paintEvent
opt.sliderPosition = value
TypeError: 'float' object cannot be interpreted as an integer
The same code works in Python 3.9.
In range_slider.py, the slider position appears to be set like so:
opt = QtGui.QStyleOptionSlider()
opt.sliderPosition = valueThis appears to be the reason for the failure because value is a float and implicit conversion fails in Python 3.10.
