这是我的代码,我想显示滑块的最小和最大范围值。我尝试了很多方法,但没有得到任何结果。请问有谁可以帮我如何显示下面图片中所示的滑块。
以下是我的代码:
from pyface.qt import QtGui, QtCore
import sys
class Example(QtGui.QWidget):
def __init__(self):
super(Example, self).__init__()
self.initUI()
def initUI(self):
self.vbox = QtGui.QVBoxLayout()
self.label3 = QtGui.QLabel()
self.slider = QtGui.QSlider()
self.slider.setMinimum(0)
self.slider.setMaximum(100)
self.slider.setTickPosition(QtGui.QSlider.TicksLeft)
self.slider.setOrientation(QtCore.Qt.Horizontal)
self.slider.setOrientation(QtCore.Qt.Horizontal)
self.vbox.addWidget(self.slider,QtCore.Qt.AlignBottom)
self.vbox.addWidget(self.label3)
self.setLayout(self.vbox)
self.setGeometry(300, 300, 300, 150)
self.slider.valueChanged.connect(self.valuechange)
self.show()
def valuechange(self):
txt = str(self.slider.value())
self.label3.setText(txt)
def main():
app = QtGui.QApplication(sys.argv)
ex = Example()
sys.exit(app.exec_())
if __name__ == '__main__':
main()
