QTerminal -d on wayland vanishes if loosing focus and can't be recovered

[stefonarch]

As it fails to register the shortcut there's no way to make it visible again.

Possible Solution

1. Allow only one instance of qterminal -d (see comment )
2. or fix the registering of the shortcut

Steps to Reproduce (for bugs)

1. Open qterminal -d on wayland

2. change focus

3. it will disappear also from taskbar like yatbfw

IMHO, the drop-down mode is already used like a single-instance app; having multiple instances of it running together doesn't make much sense under X11 either.

[yan12125]

The current qterminal already allows showing/hiding the dropdown window via a dbus method. For example:

qdbus org.lxqt.QTerminal-612287 / org.lxqt.QTerminal.Process.toggleDropdown

However, the service name is not fixed, as dbus interfaces in qterminal are designed to support multiple instances. Moving to a single-instance model is a big work and I don't think I can do it in near future. See also https://github.com/lxqt/qterminal/issues/644 for previous discussions about single-instance model.

Could dbus-send something be used with a wildcard which always matches the dropdown terminal?

This could be used in a shortcut on all wayland compositors. Looking for the clients class there are the same, would it be possibile to have a different class for the dropdown-window?

I guess no direct way for current qterminal. You will need a script to iterate over possible dbus interface names.

Looking for the clients class there are the same, would it be possibile to have a different class for the dropdown-window?

Most likely possible with some code changes. That being said, I prefer a platform-independent way that is independent of Wayland or X11 properties. A dbus property may be better.

@stefonarch @yan12125 Using DBus to send a command is possible, just not in a way you might expect. Instead of using qdbus org.lxqt.qterminal... don't you think it's easier to use qterminal --toggle ?

If only a single instance of QTerminal in the drop-down mode is allowed, you should be able to use a property (IsDropDown), search all the qterminal dbus services, and match the one where IsDropDown is true. Send a request to that service. If no instance is found, then do nothing.

[yan12125]

Sure, a command line option is better. It may be non-trivial and I don't have time to look into it yet, though. As usual, patches are welcome.

[stefonarch]

If only one instance is running this works:

#!/bin/bash
# Helper script for qterminal -d
ID=$(qdbus |grep QTermin|awk '{$1=$1};1')

qdbus "$ID" / org.lxqt.QTerminal.Process.toggleDropdown

EDIT: working version for more instances:

#!/bin/bash
while IFS= read -r line; do
    qdbus "$line" / org.lxqt.QTerminal.Process.toggleDropdown
done < <(qdbus | grep QTermin | awk '{$1=$1};1')
