wxpython widgets wx.Slider

wx.Slider is a widget that has a simple handle. This handle can be pulled back and forth. This way we can choose a specific task.

 
import wx


class Example(wx.Frame):
           
    def __init__(self, *args, **kw):
        super(Example, self).__init__(*args, **kw) 
        
        self.InitUI()
        
    def InitUI(self):   

        pnl = wx.Panel(self)

        sld = wx.Slider(pnl, value=200, minValue=150, maxValue=500, pos=(20, 20), 
            size=(250, -1), style=wx.SL_HORIZONTAL)
        
        sld.Bind(wx.EVT_SCROLL, self.OnSliderScroll)
        
        self.txt = wx.StaticText(pnl, label='200', pos=(20, 90))               
        
        self.SetSize((290, 200))
        self.SetTitle('wx.Slider')
        self.Centre()
        self.Show(True)    

    def OnSliderScroll(self, e):
        
        obj = e.GetEventObject()
        val = obj.GetValue()
        
        self.txt.SetLabel(str(val))
