Editing the Kanban board doesn't work on wayland

[zjeffer]

But it does work with XWayland (running notes with --platform xcb)

[nuttyartist]

Why?

[zjeffer]

No idea. Doubleclicking the text selects it but typing doesn't edit it. The checkboxes work fine.

[nuttyartist]

Any error? Just editing the text doesn't work or anything else? Everything shows up normally tho (could you share a screenshot)?

[zjeffer]

No errors in the terminal. Here's a video:

That's odd! Do you think you can run a simeple QML test with just TextArea {} and TextField {} Qt Quick componenets to see if it's an upstream issue with Qt and Wayland?

[guihkx]

Revisiting this, and it's still reproducible with Qt 6.6.1 on Wayland (KDE Plasma 5.27).

Do you think you can run a simeple QML test with just TextArea {} and TextField {} Qt Quick componenets to see if it's an upstream issue with Qt and Wayland?

Is this a good example?

// test.qml
import QtQuick 2.12
import QtQuick.Controls 2.12

Rectangle {
    width: 300
    height: 100
    Text {
        id: taskTextNonEditable
        width: 300
        text: "Double click here to edit me!"
        font.pointSize: 15
        textFormat: TextEdit.MarkdownText
        wrapMode: Text.Wrap

        MouseArea {
            anchors.fill: parent

            onDoubleClicked: {
                taskTextNonEditable.visible = false;
                taskTextEdit.visible = true;
                taskTextEdit.cursorPosition = taskTextEdit.length;
                taskTextEdit.forceActiveFocus();
                taskTextEdit.focus = true;
            }
        }
    }
    TextArea {
        id: taskTextEdit
        width: 300
        text: taskTextNonEditable.text
        font.pointSize: 15
        textFormat: TextEdit.PlainText
        wrapMode: Text.Wrap
        visible: false
        background: Rectangle {
            radius: 5
            color: "#efefef"
        }
    }
}

If I run that with qml6 test.qml, I'm able to edit the text inside the textarea on Wayland:

qml-test-wayland.mp4

[nuttyartist]

Yes, that should do. Can you try importing this as well?

import QtQuick.Controls.Universal 2.12

[guihkx]

Same result: Editing the text works.

[nuttyartist]

What about: import QtQuick.Controls.Material 2.12?

[guihkx]

That one made things a bit more weird while editing the text, but it still works (in the video below I first edit without the import, and then after that I edit with the import):

qml-test-wayland-2.mp4

[nuttyartist]

Hmm. still works. Very odd! This is the code of CustomTextArea (https://github.com/nuttyartist/notes/blob/master/src/qml/CustomTextArea.qml) in one file for convenience. Can you try it:

EDIT: Changed import versions.

import QtQuick 2.12

Typing still works:

qml-test-wayland-3.mp4

[nuttyartist]

Then, it's not immediately clear why on Wayland editing doesn't work in the Kanban. Needs deeper inspection.

[guihkx]

Revisiting as of Qt 6.7.1, and the issue is still present only on Wayland, unfortunately.

[nuttyartist]

That's very annoying. What distro has built-in Wayland that I can spin up to test this?

EDIT: Or can i just use my current PopOS machine? (Don't know much about Wayland)

[guihkx]

The latest version of Fedora is a probably a good choice, I think.

@nuttyartist Though you can probably use Wayland with Pop!_OS too: Logout from the current session and choose "GNOME" (and not "GNOME (Legacy)" or "GNOME (X11)" or whatever they call it) from the login manager screen.

[nuttyartist]

I believe this has something to do with the use of QWindowContainer (i.e. spawning a QML app inside a QWidget application). I just noticed that Daino Notes doesn't work in Wayland (unless used with the flag @zjeffer mentioned). But I checked a minimal example with a QML inside QWidget via QWindowContainer and a regular QML app and the regular worked without issues. I'll try to file a bug report.

If you do, please share the link to the bug report with us too. :)
