double valued gauge in wxpython

Does anyone know of a double valued gauge in wxPython? I would like to show the range of a set of data that has been selected, I have the max and min values of the gauge and then I'd like to highlight the region of the gauge between two values. The normal 开发者_运维百科wx.Gauge highlights from the gauge minimum (always the bottom of the gauge) to the set value.

Thanks

I'm not aware of any built-in widgets with the appearance of wx.Gauge that can do what you're looking for.

One option with a different appearance is RulerCtrl, which can give you two value indicators on a scale with whatever range you want. It just takes a bit of extra work to adapt it since not all of its properties are exposed in the listed methods. Quick example:

import wx
import wx.lib.agw.rulerctrl as rc

class MinMax(rc.RulerCtrl):
    def __init__(self, parent, range_min, range_max, orient=wx.HORIZONTAL):
        rc.RulerCtrl.__init__(self, parent, orient)

        self.SetRange(range_min, range_max)
        self.LabelMinor(False)
        self.range_min = range_min
        self.range_max = range_max

        self.AddIndicator(wx.NewId(), range_min)
        self.AddIndicator(wx.NewId(), range_max)

        self.Bind(rc.EVT_INDICATOR_CHANGING, self.OnIndicatorChanging)

    def GetMinIndicatorValue(self):
        return self._indicators[0]._value

    def GetMaxIndicatorValue(self):
        return self._indicators[1]._value

    def SetMinIndicatorValue(self, value):
        # Value must be within range and <= Max indicator value.
        if value < self.range_min or value > self.GetMaxIndicatorValue():
            raise ValueError('Out of bounds!')
        self._indicators[0]._value=value
        self.Refresh()

    def SetMaxIndicatorValue(self, value):
        # Value must be within range and >= Min indicator value.
        if value > self.range_max or value < self.GetMinIndicatorValue():
            raise ValueError('Out of bounds!')
        self._indicators[1]._value=value
        self.Refresh()

    def OnIndicatorChanging(self, evt):
        # Eat the event so the user can't change values manually.
        # Do some validation here and evt.Skip() if you want to allow it.
        # Related: EVT_INDICATOR_CHANGED
        pass


class MainWindow(wx.Frame):
    def __init__(self, parent, id, title):
        wx.Frame.__init__(self, parent, id, title)

        self.minmax = MinMax(self, 0, 100)
        self.minmax.SetSpacing(20)
        self.minmax.SetMinIndicatorValue(30)
        self.minmax.SetMaxIndicatorValue(84)
        self.Show()

app = wx.App(redirect=False) 
frame = MainWindow(None, wx.ID_ANY, "Range Indicator") 
app.MainLoop()
