QML ToolBar: Binding loop detected for property "implicitHeight"

sush123

Hi All,

I get this issue for ToolBar

ToolBar {
id: titleBar
RowLayout {
anchors.fill: parent
ToolButton {
action: dirUpAction
style: IconButtonStyle { }
Layout.maximumWidth: height * 1.5
}
TextField {
id: currentPathField
Layout.fillWidth: true
function doAccept() {
root.clearSelection()
if (root.addSelection(root.pathToUrl(text)))
root.accept()
else
root.folder = root.pathFolder(text)
}
onAccepted: doAccept()
}
}
}

How can i fix this?

@sush123 hi
Are you sure the error comes from this code? I have no error when i test this.
what is your Qt and QtQuick.Controls version ?

import QtQuick 2.12
import QtQuick.Controls 2.12
import QtQuick.Window 2.12
import QtQuick.Layouts 1.3

Window {
    visible: true
    width: 300
    height: 300

    ToolBar {
        id: titleBar
        width: parent.width
        RowLayout {
            anchors.fill: parent
            ToolButton {
                Layout.maximumWidth: height * 1.5
            }

            TextField {
                id: currentPathField
                Layout.fillWidth: true
                function doAccept() {
                    root.clearSelection()
                    if (root.addSelection(root.pathToUrl(text)))
                        root.accept()
                    else
                        root.folder = root.pathFolder(text)
                }
                onAccepted: doAccept()
            }
        }
    }
}

//main.cpp

#include <QGuiApplication>
#include <QQmlApplicationEngine>
#include <QApplication>

int main(int argc, char *argv[])
{
    QApplication app(argc, argv);
    QQmlApplicationEngine engine;
    const QUrl url(QStringLiteral("qrc:/main.qml"));
    QObject::connect(&engine, &QQmlApplicationEngine::objectCreated,
                     &app, [url](QObject *obj, const QUrl &objUrl) {
        if (!obj && url == objUrl)
            QCoreApplication::exit(-1);
    }, Qt::QueuedConnection);
    engine.load(url);
    return app.exec();
}

i have Qt 5.14.0
