I am trying to get a dynamic text displayed in the system tray (this will be 2 numbers (from 1 to 100) changing every 2 minutes).

I found this script as a starting point (but I am not commited to it!).

But I get this error :

TypeError: Image.SetData(): arguments did not match any overloaded call:
 overload 1: argument 1 has unexpected type 'str'
 overload 2: argument 1 has unexpected type 'str'
OnInit returned false, exiting...

The relevant part of the code is:

def Get(self,l,r):
 s=""+self.s_line
 for i in range(5):
 if i<(5-l):
 sl = self.sl_off
 else:
 sl = self.sl_on

 if i<(5-r):
 sr = self.sr_off
 else:
 sr = self.sr_on

 s+=self.s_border+sl+self.s_point+sr+self.s_point
 s+=self.s_border+sl+self.s_point+sr+self.s_point
 s+=self.s_line

 image = wx.EmptyImage(16,16)
 image.SetData(s)

 bmp = image.ConvertToBitmap()
 bmp.SetMask(wx.Mask(bmp, wx.WHITE)) #sets the transparency colour to white 

 icon = wx.EmptyIcon()
 icon.CopyFromBitmap(bmp)

 return icon

I add to update the script by adding import wx.adv and by replacing the 2 wx.TaskBarIcon by wx.adv.TaskBarIcon.

I am on Windows 10 with Python 3.6

I found another way using Pillow and infi.systray

# text to image : Pillow (https://pillow.readthedocs.io/en/latest/handbook/tutorial.html - simple code sample: https://code-maven.com/create-images-with-python-pil-pillow)
# icon in systray : infi.systray (https://github.com/Infinidat/infi.systray and https://stackoverflow.com/a/54082417/3154274)

# inspired by https://www.reddit.com/r/learnpython/comments/a7utd7/pystray_python_system_tray_icon_app/

# install PIL : pip install Pillow
# install infi.systray : pip install infi.systray

from infi.systray import SysTrayIcon
from PIL import Image, ImageDraw,ImageFont
import time

image= "pil_text.ico"
n=1
while True:
 # create image
 img = Image.new('RGBA', (50, 50), color = (255, 255, 255, 90)) # color background = white with transparency
 d = ImageDraw.Draw(img)
 d.rectangle([(0, 40), (50, 50)], fill=(39, 112, 229), outline=None) # color = blue

 #add text to the image
 font_type = ImageFont.truetype("arial.ttf", 25)
 a= n*10
 b = n*20
 d.text((0,0), f"anb", fill=(255,255,0), font = font_type)

 img.save(image)


 # display image in systray 
 if n==1:
 systray = SysTrayIcon(image, "Systray")
 systray.start()
 else:
 systray.update(icon=image)
 time.sleep(5)
 n+=1
systray.shutdown()

The following uses the current minute and second as a replacement for your line numbers but can be easily adapted.

import wx
import wx.adv
import datetime
from wx.lib.embeddedimage import PyEmbeddedImage
#
# A white box 28x28 pixels

toggletest = PyEmbeddedImage(

class TaskBarIcon(wx.adv.TaskBarIcon):
 def __init__(self, frame):
 self.frame = frame
 self.toggle = 0
 wx.adv.TaskBarIcon.__init__(self)
 self.Bind(wx.adv.EVT_TASKBAR_LEFT_DOWN, self.OnToggle)
 self.font = wx.SystemSettings.GetFont(wx.SYS_SYSTEM_FONT)
 self.font.SetPointSize(8)
 self.OnSetIcon(self.NewIcon())

 def CreatePopupMenu(self):
 menu = wx.Menu()
 togglem = wx.MenuItem(menu, wx.NewId(), 'Toggle Icon')
 menu.Bind(wx.EVT_MENU, self.OnToggle, id=togglem.GetId())
 menu.Append(togglem)
 menu.AppendSeparator()
 flashm = wx.MenuItem(menu, wx.NewId(), 'Flashing Icon')
 menu.Bind(wx.EVT_MENU, self.OnTimer, id=flashm.GetId())
 menu.Append(flashm)
 menu.AppendSeparator()
 quitm = wx.MenuItem(menu, wx.NewId(), 'Quit')
 menu.Bind(wx.EVT_MENU, self.OnQuit, id=quitm.GetId())
 menu.Append(quitm)
 return menu

 def NewIcon(self):
 bitmap = wx.Bitmap(toggletest.Bitmap)
 dc = wx.MemoryDC(bitmap)
 # Use current time as text, for want of something useful
 now = datetime.datetime.today()
 text = str(now.minute)+"n"+str(now.second)
 dc.SetFont(self.font)
 dc.DrawText(text, 2, 2)
 del dc
 return bitmap

 def OnSetIcon(self, bitmap):
 icon = wx.Icon()
 icon.CopyFromBitmap(bitmap)
 self.SetIcon(icon)

 def OnToggle(self, event):
 bitmap = self.NewIcon()
 self.OnSetIcon(bitmap)

 def OnTimer(self,event):
 self.timer = wx.Timer(self)
 self.Bind(wx.EVT_TIMER, self.OnUseTimer)
 self.timer.Start(1000)

 def OnUseTimer(self,event):
 self.OnToggle(None)

 def OnQuit(self, event):
 self.RemoveIcon()
 wx.CallAfter(self.Destroy)
 self.frame.Close()

if __name__ == '__main__':
 app = wx.App()
 frame=wx.Frame(None)
 TaskBarIcon(frame)
 app.MainLoop()

The result is the white box below with 22 above 33
