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?

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:

[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):

[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:

[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.
