You need to paint a view before you can show a button. You could create
a QMainWindow and add the QPushButton in there I suppose, but I'd
strongly recommend to not use QWidget, but instead QML.
As a quick start start:
main.cpp:
#include <QQuickView>
#include <QCoreApplication>
int main(int argc, char *argv[]) {
QGuiApplication app(argc, argv);
QQuickView v;
v.setSource("/path/to/some/qmlfile.qml");
v.show();
return app.exec();
}
/path/to/some/qmlfile.qml:
import QtQuick 2.4
import Ubuntu.Components 1.3
MainView {
Button {
anchors.centerIn: parent
text: "click me"
onClicked: print("button clicked")
}
}
signature.asc
