wallpaper folders cannot be changed

[Heliotrop]

I could remove those which were originally present - because they pointed nowhere. But now I'm stuck to add new ones

Any hint how to add this manually (config file?)

I just did build from source, and I still can not add folders, so it might not be a flatpak only issue.

[evfool]

FYI: The config file to add some more folders should be ~/.config/hydrapaper

[GabMus]

That's very strange. You can add new folders using this button

If you already tried, did it work? If not, what happened when you pressed that button?

Also, please both @evfool and @Heliotrop tell me what distribution and desktop environment you're running.

[GabMus]

BTW, the config file is a simple json and the complete path is ~/.config/hydrapaper.json

[evfool]

@GabMus : changing the config file manually did solve it, the tool is great, thanks for doing it, I've been manually creating triple-monitor wallpapers until now.
Regarding my environment: I am on Fedora 27 (wayland, gnome shell, etc), installed HydraPaper both from flatpak and was running it from source. I saw the dropdown, but clicking it did nothing.
I just realized that it works (opens the combo) if I open the GtkPopover (wallpapers folder), change focus to another window, then click the down arrow to open the dropdown, but if clicking the dropdown arrow after opening the popover without switching focus to another window it does not open the filepicker. I hope this helps.

[GabMus]

@evfool great to know that it works now, and that it works with a triple monitor setup! I didn't test that since I only have 2, so thanks for that!

As for this switching focus bug, that's really weird if you ask me. I didn't experience it on my Arch system. Maybe (but can't be sure of it) this problem is wayland related? Try running on xorg and report back if it works or not.

[evfool]

Indeed, it works if running with GDK_BACKEND=x11 flatpak run org.gabmus.hydrapaper, so it surely is Wayland. Probably a simple testcase will also reproduce it, I guess it deserves a report for GTK.

[GabMus]

Yeah, totally sounds like a Gtk issue. Will try to report that

[Heliotrop]

Yes, tried to use the button, but nothing happens. Sorry, but can you show an example config syntax?

[Heliotrop]

... and yes, I'm using wayland
json looks like:
{"monitors": {"DEL - DVI-D-1": null, "GSM - DVI-I-1": null}, "selection_mode": "double", "wallpapers_paths": []}

[evfool]

@Heliotrop: try clicking the Wallpapers folder, focus another window, and click the dropdown afterwards, it did the trick for me. Regarding the config file, just add whatever folders you want to the wallpapers_path, e.g. "wallpapers_paths": ["/home/username/Pictures","/usr/share/backgrounds/gnome"] is the default, I think

[GabMus]

"wallpapers_paths": ["/home/username/Pictures","/usr/share/backgrounds/gnome"] is the default, I think

yes, it is.

@Heliotrop If you want to re-add the default folders in an easier way, just run rm ~/.config/hydrapaper.json. This will re-generate a new config file with default values on startup.

[Heliotrop]

Thanks, yes, putting it manually worked for me (Ubuntu 17.10). Great tool!

[GabMus]

Awesome. I'm sorry you're getting this issue with the file chooser, it's apparently a gtk bug and I can't do much about it unfortunately.

[Heliotrop]

I understand. It works like a charm now. Selecting and Applying is working since the path is correct.

Thanks again for your help

PS.: There's still a couple of bugs with wayland, since Ubuntu switched there from Unity. Sometimes Nautilus freezes completely ... but this is an entire different story.

[GabMus]

@Heliotrop You can still fallback to the xorg session if you want to.

[GabMus]

In 26b5a7b I did a design change that removes the combobox/filechooserbutton in favor of a simple button. This should fix the problem on wayland. Please test it and report back.
