superqt QLabeledRangeSlider no labels after setValue() int the second time

QLabeledRangeSlider no labels after setValue() int the second time

Open looninho opened this issue 3 years ago • 2 comments

update values the second time removes all labels When I create my_slider QLabeledRangeSlider object then set the values with my_slider.setValue(mylist_1) every thing works fine but when I set a new dataset with my_slider.setValue(mylist_2), only handles updated all labels disappear.

To Reproduce Steps to reproduce the behavior:

create a QWidget to host the QLabeledRangeSlider slider
create a QLabeledRangeSlider object as child then set its value with .setValue() method
create a QPushButton to set new values then connect its signal clicked to an update method
see error: the slider updates with no label at each handle, only range label displayed.

example code

import sys, os

from PySide6.QtWidgets import QApplication, QWidget, QPushButton
from PySide6.QtCore import Qt
from superqt import QLabeledRangeSlider

class Window(QWidget):
  def __init__(self, parent=None):
    super(Window, self).__init__(parent)
    sl = tuple([0, 90, 210, 259, 374])

    self.main_slider = QLabeledRangeSlider(parent=self)
    self.main_slider.setOrientation(Qt.Horizontal)
    width = self.geometry().width()
    self.main_slider.setMinimumWidth(width)

    self.main_slider.setRange(sl[0], sl[-1])
    self.main_slider.setValue(tuple(sl))

    btn = QPushButton(self)

    btn.clicked.connect(self.update)


  def update(self):
    sl = tuple([1261, 1281, 1334, 1365, 1697, 1871, 1916])
    self.main_slider.setRange(sl[0], sl[-1])
    self.main_slider.setValue(sl)


if __name__ == '__main__':
  app = QApplication([])
  win = Window()
  win.show()
  sys.exit(app.exec())

Expected behavior expected labels .at each handle.
