style. Unfortunatelly this option is only available in Windows.
So I decide to create a small widget with two sliders to select the maximum and minimum time. If the minimum goes over the maximum the maximum is updated and viceversa. The selected values are updated as labels.
This is the code:
#!/usr/bin/python
# -*- coding: utf-8 -*-
import wx
class RangeSlider (wx.Panel):
MAX_VALUE = 1000
def __init__ (self, parent, minTime, maxTime):
super(RangeSlider, self).__init__(parent, wx.ID_ANY)
self.minTime = minTime
self.maxTime = maxTime
sizer = wx.FlexGridSizer (rows=2, cols = 3, vgap = 5, hgap = 5)
self.sldMax = wx.Slider(self, value=RangeSlider.MAX_VALUE, minValue=0,
maxValue=self.MAX_VALUE,
style=wx.SL_HORIZONTAL )
self.sldMin = wx.Slider (self, value=0, minValue=0,
maxValue=self.MAX_VALUE,
style =wx.SL_HORIZONTAL )
self.sldMax.Bind(wx.EVT_SCROLL, self.OnSliderScroll)
self.sldMin.Bind (wx.EVT_SCROLL, self.OnSliderScroll2)
self.txtMax = wx.StaticText(self, label= self.formatTime (self.maxTime))
self.txtMin = wx.StaticText(self, label=self.formatTime (self.minTime))
lab1 = wx.StaticText (self, label="Min " + self.formatTime (self.minTime))
lab2 = wx.StaticText (self, label="Max " + self.formatTime (self.maxTime))
sizer.Add (lab1, 0, wx.LEFT, 10)
sizer.Add (self.sldMax, 1, wx.EXPAND)
sizer.Add (lab2, 0, wx.RIGHT, 10)
sizer.Add (self.txtMin, 1, wx.ALIGN_CENTER)
sizer.Add (self.sldMin, 1, wx.EXPAND)
sizer.Add (self.txtMax, 1, wx.ALIGN_CENTER)
sizer.AddGrowableCol (1, 1)
self.SetSizer (sizer)
def formatTime (self, t):
return "%02d:%02d:%02d" % (t / 3600, (t%3600)/60, t%60)
def formatValue (self, v):
t = v * (self.maxTime - self.minTime) / 1000
return self.formatTime (t)
def OnSliderScroll(self, e):
val = self.sldMax.GetValue()
valMin = self.sldMin.GetValue ()
if valMin > val:
self.sldMin.SetValue (val)
self.txtMin.SetLabel (self.formatValue(val))
self.txtMax.SetLabel(self.formatValue(val))
def OnSliderScroll2 (self, e):
val = self.sldMin.GetValue()
valMax = self.sldMax.GetValue ()
if valMax < val:
self.sldMax.SetValue (val)
self.txtMax.SetLabel (self.formatValue(val))
self.txtMin.SetLabel(self.formatValue(val))
class Example(wx.Frame):
def __init__(self, parent, minTime, maxTime):
""" The time is seconds """
super(Example, self).__init__(parent, wx.ID_ANY)
self.InitUI(minTime, maxTime)
def InitUI(self, minTime, maxTime):
rangeSlider = RangeSlider (self,minTime, maxTime)
self.SetTitle('RangeSlider')
self.Centre()
self.Show(True)
def main():
ex = wx.App()
Example(None, 0, 7200)
ex.MainLoop()
if __name__ == '__main__':
main()
