@SGaist Thanx mate :) Qt rox :D

@jsulm Oh. I haven't considered that. I'm definitely going to try that. I don't know why it didn't came to my mind. Thank you very much. I really appreciate your advice. I have been stuck at this problem for a week. I am glad there are people who are willing to help beginners.

need to check Qt classes for system settings and native look and feel, and of adopting those changes for App. Thanks,

In my understanding this is exact what onClicked does. From the online documentation: "A click is defined as a press followed by a release, both inside the MouseArea (pressing, moving outside the MouseArea, and then moving back inside and releasing is also considered a click)." MouseArea { anchors.fill: parent onClicked: console.log("released") onPressed: console.log("pressed") }

I create MyClass and pass 4 images to QML in main.cpp class.h #ifndef MYCLASS_H #define MYCLASS_H #include <QDebug> #include <QObject> class MyClass : public QObject { Q_OBJECT Q_PROPERTY(QString imagePath READ imagePath WRITE setImagePath NOTIFY pathChanged); public: explicit MyClass(QObject *parent = 0); MyClass(QString path) { m_imagePath = path; } QString imagePath(); void setImagePath(const QString & path); signals: void pathChanged(QString path); private: QString m_imagePath; }; #endif // MYCLASS_H main.cpp QApplication app(argc, argv); app.setWindowIcon(QIcon("qrc:/images/logo.ico")); QQmlApplicationEngine engine; engine.load(QUrl(QStringLiteral("qrc:/main.qml"))); QList<QObject*> dataList; dataList.append(new MyClass("/images/images/zaglowek.png")); dataList.append(new MyClass("/images/images/pilot.png")); dataList.append(new MyClass("/images/images/uklad_jezdny.png")); dataList.append(new MyClass("/images/images/nozne_sterowanie.png")); engine.rootContext()->setContextProperty("myModel", QVariant::fromValue(dataList)); For Now MyClass has only image path, but it will also set state (checked-unchecked) and animation (enable-disable). I would like to reload this QList ( with another images, states etc. ) when button ( one of three ) is clicked ( TButton.qml ). How to do it ? Please help.

@JulienD Np. You can style the whole application however. All controls etc can be controlled with style sheet. Just not Caption :)

I have the same problem ... ... there is a bug-report (https://bugreports.qt.io/browse/QTIFW-711) ... but no solution.

Resolved. When i played with second usb monitor i changed first hdmi monitor modes depth to 16. Now i set 24 bits in xorg.conf and all UI is OK. Thanks for all.
