Global Shortcuts functionality crashes on wayland wlroots!

[RyanOrigens]

Whenever i try to utilize the OCR functionality through the global shortcuts it immediately crashes;

├── method void io.crow_translate.CrowTranslate.MainWindow.recognizeScreenArea();
├── method void io.crow_translate.CrowTranslate.MainWindow.translateScreenArea();
├── method void io.crow_translate.CrowTranslate.MainWindow.delayedRecognizeScreenArea();
├── method void io.crow_translate.CrowTranslate.MainWindow.delayedTranslateScreenArea();

If i try to launch the functionality through the gui clicking on the icons it works;

Also when i try to launch translate selection in popup mode, if it loses the focus a couple times it also crashes, the only way to utilize it by now is utilizing it with the "Translation Mode: Main Window"

├── method void io.crow_translate.CrowTranslate.MainWindow.translateSelection();

Tested on Sway/Hyprland!

[Shatur]

Can't reproduce on my machine. Probably something specific to Wayland. Maybe a bug in our OCR provider for Wayland.

[RyanOrigens]

This is the error when i try to execute recognizeScreenArea from the terminal,

Error: org.freedesktop.DBus.Error.NoReply
Message recipient disconnected from message bus without replying

[Shatur]

For some reason it can't access xdg desktop portal to request the screen area.
Another limitation of Wayland, I implemented different providers for different DE's: https://github.com/crow-translate/crow-translate/blob/master/src/ocr/screengrabbers/waylandgnomescreengrabber.cpp
You can try to execute the DBus command I execute from the code (to get the area) and see if it works.

I didn't really understand what to do, i tried excuting dbus-send --type=method_call --dest=org.gnome.Shell /org/gnome/Shell/Screenshot org.gnome.Shell.Screenshot.Screenshot, but of course nothing happened.

[Shatur]

Check if you even have this D-Bus interface. Something like this:

qdbus org.gnome.Shell /org/gnome/Shell/Screenshot

[RyanOrigens]

Service 'org.gnome.Shell' does not exist.

[RyanOrigens]

Dbus is here i can exec other keybindings. "dbus-send --type=method_call --dest=io.crow_translate.CrowTranslate /io/crow_translate/CrowTranslate/MainWindow io.crow_translate.CrowTranslate.MainWindow.translateSelection"

[Shatur]

Expected, it's because you have Sway. Try this:

qdbus org.freedesktop.portal.Desktop /org/freedesktop/portal/desktop

Now check if you have the following method:

qdbus org.freedesktop.portal.Desktop /org/freedesktop/portal/desktop org.freedesktop.portal.Screenshot

[RyanOrigens]

Error: org.freedesktop.DBus.Error.UnknownMethod
No such interface “org.freedesktop.portal” on object at path /org/freedesktop/portal/desktop

[Shatur]

Not sure what happens here, it's either something changed on Sway or something wrong with your configuration.
Can't help much here, sorry.

[RyanOrigens]

i'm on hyprland

[Shatur]

Then maybe it doesn't have this interface and in order to retrieve a screenshot you need other D-Bus command.
Wayland is quite painful for developers because things like this aren't standardized.
