Hello,
i just started learning QML and i have a really simple problem: i want to change the size of my main window with my cpp code and i just does not work :(
Here is a little example:
import QtQuick 2.0
Rectangle {
width: 360
height: 360
color: "white"
Rectangle {
x: 200
y: 203
width: 96
height: 92
color: "yellow"
objectName: "objectName"
}
}
#include <QtGui/QGuiApplication>
#include "qtquick2applicationviewer.h"
#include "qqmlengine.h"
#include "qqmlcomponent.h"
#include "qquickitem.h"
int main(int argc, char *argv[])
{
QGuiApplication app(argc, argv);
QtQuick2ApplicationViewer viewer;
viewer.setMainQmlFile(QStringLiteral("qml/Test/main.qml"));
QQuickItem *object = viewer.rootObject();
QQuickItem *rect = object->findChild<QQuickItem*>("objectName");
object->setProperty("width", 20);
object->setProperty("height", 20);
object->setProperty("color", "black");
rect->setProperty("width", 10);
rect->setProperty("height", 10);
viewer.showExpanded();
return app.exec();
}
Those two lines just don’t do anything:
object->setProperty("width", 20);
object->setProperty("height", 20);
Changing the color of object works. Changing width and height of rect also works. The only thing that does not work is changing the size of object and i cant figure out why. Changing width and height in my QML code also works.
Can anyone please tell me how i can change this size?? Thanks! :)
