System tray applications (or menu bar applications) can be useful for making common functions or information available in a small number of clicks. For full desktop applications they're a useful shortcut to control apps without opening up the whole window.
Qt provides a simple interface for building cross-platform system tray (Windows) or menu bar (MacOS) apps.
On Mac, all the apps that Iād want to open are in the /Applications directory and for the most part all have a.app extension, so we can get their names using something like this: d = '/Applications' apps = list(map(lambda x: x.split('.app')0, os.listdir(d))) List the directory and remove the extension. The right and wrong way to set Python 3 as default on a Mac There are a lot of ways to configure Python 3. TL;DR if you're looking for a quick answer, jump down to this section to.
Minimal example
Below is a minimal working example for showing an icon in the toolbar/system tray with a menu. The action in the menu isn't connected and so doesn't do anything yet.
You'll notice that there isn't a
QMainWindow
, simply because we don't actually have any window to show. You can create a window as normal without affecting the behaviour of the system tray icon. You'll need an icon for this example ā I recommend the fugue icon set.
The default behaviour in Qt is to close an application once all the active windows have closed. This won't affect this toy example, but will be an issue in application where you do create windows and then close them. Setting `app.setQuitOnLastWindowClosed(False)` stops this and will ensure your application keeps running.

The provided icon shows up in the toolbar (you can see it on the left).

Clicking on the icon shows the added menu.

This application doesn't do anything yet, so in the next part we'll expand this example to create a mini colour-picker.
Color tray
Below is a more complete working example using the built in
QColorDialog
from Qt to give a toolbar accessible color picker. The menu lets you choose to get the picked color as HTML-format #RRGGBB
, rgb(R,G,B)
or hsv(H,S,V)
.python
As in the previous example there is no
QMainWindow
for this example. The menu is created as before, but adding 3 actions for the different output formats. Each action is connected to a specific handler function for the format it represents. Each handler shows a dialog and, if a color is selected, copies that color to the clipboard in the given format. Wallpaper apps free download.As before, the icon appears in the toolbar.

Clicking the icon shows a menu, from which you can select the format of image you want to return.
Options to return chosen colour (hex, RGB or HSV)

PyQt provides access to system dialogs, such as this Mac colour picker
Select the colour you want and click OK. The chosen colour will be copied to the clipboard in the requested format. The formats available will product the following output:

One simple and nice improvement would be to make the previously-selected colours available to re-copy in other formats. You could do this by storing the colour result value from the existing menu. Then add 3 more options, which show (on the menu) their return values ā clicking these just copies that value to the clipboard.
