I\'d just need a quick example on how to easily put an icon with python on my systray. This means: I run the program, no window shows up, just a tray icon (I\'ve got a png f
Yes. There is a cross-platform example on wiki.wxpython.org that I've tested with python 2.7 (minconda install) on macOS High Sierra (10.13.3), Windows 7, and gnome 3/centos7. It is here (ignore the page title): https://wiki.wxpython.org/Custom%20Mac%20OsX%20Dock%20Bar%20Icon
Small mods are needed for python 3.6:
Gnome 3 required installation of TopIcons Plus.
Since you don't want to have the window display (" no window shows up, just a tray icon"), simply comment out the following line (though you still want to keep the wx.Frame parent):
frame.Show(True)
And since you want to use your own .png icon, remove the WXPdemo image and embeddedimage stuff and replace
icon = self.MakeIcon(WXPdemo.GetImage())
with, for example
icon = wx.Icon('icon.png')
In my experience, this will provide a good start for adapting or extending further.
