How to use qtvirtualkeyboard with qwidget?

Paraddi

Couple of questions:

Where to register KeyboardPanel to qml ?
What does "CM780.KeyboardPanel" means
qmlRegisterSingletonType<KeyboardPanel>("CM780.KeyboardPanel", 1, 0, "KeyboardPanel", qobject_singletontype_provider);

You can register it at the constructor, or others before you use it. It makes the qml to KNOWN the type of KeyboardPanel
For "CM780.KeyboardPanel", it is just a NAME, so that you can import it in qml, for example, your do like this

qmlRegisterSingletonType<KeyboardPanel>("YourAppName.KeyboardPanel", 1, 0, "KeyboardPanel", qobject_singletontype_provider);

then you can import it like this:

import QtQuick 2.7
import QtQuick.Window 2.0
import QtQuick.VirtualKeyboard 2.0
import QtQuick.VirtualKeyboard.Settings 2.0

//you can import it here like the qt quick modules like aboves
import YourAppName.KeyboardPanel 1.0

Note: for this case, I register it as singleton type, so you can invoke the method by KeyboardPanel.yourMethod()

@SGaist i am attach the virtual keybord with widgets using :

QQuickView *view = new QQuickView();
QWidget *container = QWidget::createWindowContainer(view, ui->verticalLayoutWidget);
container->setMinimumSize(240, 320);
container->setMaximumSize(240, 320);

 //container->setAttribute(Qt::WA_AcceptTouchEvents);
 //container->setAttribute(Qt::WA_InputMethodEnabled, true);
 container->setAttribute(Qt::WA_AcceptTouchEvents);
 container->setFocusPolicy(Qt::NoFocus);
 //container->setInputMethodHints(inputMethodHints() | Qt::InputMethodHint::ImhDigitsOnly);
 view->setSource(QUrl("qrc:/main.qml")); // Fetch this url by right clicking on your resource file.

// view->setSource();

 ui->verticalLayout->addWidget(container);

then virtual keyboard attatched with widgets but when i write in QLine edit it throw following error :
qt.virtualkeyboard: InputContext::sendKeyClick(): no focus to send key click - QGuiApplication::focusWindow() is: QQuickView(0x55cb3cf78130)

Why are you using a QQuickView if you want to use QLineEdit ?

Hii, @SGaist
i am using QQuickView , because i want to attatch virtual keyboard on screen

SGaist

There's no need for a QQuickView to use Qt VirtualKeyboard.
