Is it possible to add toggle switches like this in wxPython?

CodePudding user response：

I asked myself a similar question last year and didn't come up with a satisfactory answer.
So I wrote my own.
I did post it on wxpython-users hosted on groups-google

With the code saved as onoffbutton.py I tend to import it with:

import onoffbutton as oob

and then use it as in the demo, something like:

self.fc_autotransparency = oob.OnOffButton(self.tab3, wx.ID_ANY)

Here's a rough and ready example. The idea is to use two images and toggle them in the toggle_sizer. The image bitmaps are named and the toggle_click method removes the one that is currently displayed from the toggle_sizer and adds the other.

import wx

TOGGLE_SIZE = (30, 15)


class MainFrame(wx.Frame):
    def __init__(self, *args, **kwargs):
        super().__init__(None, *args, **kwargs)
        self.Title = 'Demonstrate toggle'

        self.panel = MainPanel(self)
        sizer = wx.BoxSizer(wx.VERTICAL)
        sizer.Add(self.panel)
        self.SetSizer(sizer)
        self.Center()
        self.Show()


class MainPanel(wx.Panel):
    def __init__(self, parent, *args, **kwargs):
        super().__init__(parent, *args, **kwargs)

        sizer = wx.BoxSizer(wx.VERTICAL)
        toggle_off_bitmap = self._toggle_image('toggle_off')
        self.toggle_sizer = wx.BoxSizer(wx.VERTICAL)
        self.toggle_sizer.Add(toggle_off_bitmap)
        sizer.Add(self.toggle_sizer)
        self.SetSizer(sizer)

    def _toggle_image(self, bitmap_name):
        toggle_bitmap = wx.Bitmap(f'{bitmap_name}.png', wx.BITMAP_TYPE_ANY)
        image = wx.Bitmap.ConvertToImage(toggle_bitmap)
        image = image.Scale(TOGGLE_SIZE[0], TOGGLE_SIZE[1])
        bitmap_image = wx.StaticBitmap(self, wx.ID_ANY, name=bitmap_name)
        bitmap_image.SetBitmap(image.ConvertToBitmap())
        bitmap_image.Bind(wx.EVT_LEFT_DOWN, self.toggle_click)
        return bitmap_image

    def toggle_click(self, event):
        toggle = event.GetEventObject().Name
        if toggle == 'toggle_off':
            toggle_bitmap = self._toggle_image('toggle_on')
        else:
            toggle_bitmap = self._toggle_image('toggle_off')
        self._clear_sizer(self.toggle_sizer)
        self.toggle_sizer.Add(toggle_bitmap)

    def _clear_sizer(self, sizer):
        for child in sizer.GetChildren():
            if child.IsSizer():
                if child.IsSizer():
                    self._clear_sizer(child.GetSizer())
            else:
                child.GetWindow().Destroy()
        sizer.Clear()


if __name__ == '__main__':
    wx_app = wx.App()
    MainFrame()
    wx_app.MainLoop()
