[BUG] Systray applet's tooltip are not dynamically resfreshed / udpated

[Antiz96]

Describe the bug

When a systray applet gets its tooltip updated, it won't be updated / refreshed dynamically in nwg-panel until you reload it (e.g. with nwg-panel -sigdwl 1).

To Reproduce

Steps to reproduce the behavior:

1. Launch any systray applet
2. Update its tooltip text (see Additional context)
3. Hover your mouse over the systray icon and see that the tooltip hasn't been updated / refreshed accordingly
4. Run nwg-panel -sigdwl 1 and see that the tooltip gets updated

Expected behavior

Systray applet's tooltip to be dynamically updated / refreshed (like it does in e.g. xfce4-panel)

Screenshots

I can record a video if it helps, just tell me :)

Desktop (please complete the following information):

• Linux distribution: Arch Linux
• Sway version sway version 1.9
• Panel version nwg-panel version 0.9.39

Additional context

I'm dynamically updating / modifying the tooltip of the systray applet for my arch-update app to include the list of pending updates (for the context, this is done by retrieving the related info from a file thanks to a python 'file watcher' directive, see changes made to the src/lib/tray.py file in Antiz96/arch-update#257). The idea is that users can see the list of pending updates by simply hovering their mouse on the systray icon.

However, it doesn't work in nwg-panel as the tooltip is not automatically refreshed / updated, which forces to reload the panel (e.g. with nwg-panel -sigdwl 1) to get "updated" tooltip. It works in other panels though, like xfce4-panel for instance.

I'm aware that this might be a bit of an unconventional way to use a tooltip but I'm still trying my luck in case this is "fixable" 😄

I remain available if you need any more information!

I'd need to set up some testing environment to deal with this issue. Let me think.

[Antiz96]

Sure no problem.

If it helps, I can guide you through a way to install & set up Arch-Update to be able to easily generate tooltip changes for its systray in your testing environment as a test case. Let me know if needed :)

[nwg-piotr]

It would be not bad. I'd be sure I'm working on the proper issue. :D

1 - Install the arch-update AUR package

2 - Assuming your test env will be using Sway / Nwg-shell: add the arch-update --tray command to your sway config to auto-start the systray at boot (you might eventually need to adding a short sleep beforehand for it to work properly, e.g. sleep 3 && arch-update --tray).
If your test env is using a desktop environment, you can run the arch-update --tray --enable command to add the tray into XDG autostart instead.

3 - Install fastfetch (random pick, will be used to trigger an update for the system and to update the tooltip accordingly): sudo pacman -S fastfetch

4 - Download an earlier version of fastfetch from Arch's archives: curl https://archive.archlinux.org/packages/f/fastfetch/fastfetch-2.25.0-1-x86_64.pkg.tar.zst -O

5 - Downgrade to the earlier version of fastfetch downloaded above: sudo pacman -U fastfetch-2.25.0-1-x86_64.pkg.tar.zst and then right click on the Arch-Update systray icon and click on "Check for updates":

This will generate a new update for your system and trigger a tooltip update accordingly, like so:

6 - You can then left click the systray applet to update your system via Arch-Update (you can answer "Y"es to all questions). This will trigger another tooltip update accordingly, like so:

You should see that you need to reload nwg-panel (e.g. with nwg-panel -sigdwl 1) to get the tooltip updated (while on other panels, like xfce4-panel for instance, it is updated in real time).

You can repeat steps 5 and 6 as much as you need to generate tooltips updates 😉

Hopefully this is clear enough 😅
Let me know if not :)

LOL, I was just about to write a python script to create an icon and update the tooltip text once a second. 🤣 Either way, this needs to wait till the evening, as I'm leaving the office in 20 minutes.

Well, sure that would work lol. Whatever feels easier to you 🤣
At least you know in which context I'm using this now 😆

Yeah no problem :) Thanks 🙏

[nwg-piotr]

It works well now.

[edit] I removed some irrelevant replies above.

[Antiz96]

I confirm it works as intended with v0.9.40! Thanks a lot :D

You are welcome! A couple of lines of code were missing. It took time to find it, as it's not my code. :)
