#include <QApplication>
#include <QQmlApplicationEngine>

#include <QDebug>
#include <QScreen>
#include <QQmlContext>
#include "globalcontrolclass.h"

int main(int argc, char *argv[])
{
    QApplication app(argc, argv);
    QQmlApplicationEngine engine;
    GlobalControlClass controlGlobal;

    QRect z = qApp->primaryScreen()->availableGeometry();
    controlGlobal.setWindowHeight(z.height());
    controlGlobal.setWindowWidth(z.width());
    if(z.height()<=0 || z.width()<=0){
        qDebug()<<"Error al obtener tamaño de la pantalla.\nNo se puede continuar asi.";
        return false;
    }
    qDebug()<<"Window Dip-> H:"<<controlGlobal.windowHeight()<<"W:"<<controlGlobal.windowWidth();

    engine.rootContext()->setContextProperty("ControlGlobal", &controlGlobal);
    engine.load(QUrl(QStringLiteral("qrc:/main.qml")));

    return app.exec();
}

我使用Qt Creator 3.3.1 Qt 5.4.1（GCC 4.6.1,64位） AMV是ARM（armeabi-v7a）目标：Android 4.4.2（API级别19）

1 个答案:

答案 0 :(得分：0)

以下列方式解决我的问题。 更改calls: - [ setContainer, [ @service_container ] ] qApp->primaryScreen()->availableGeometry();，如果我获得了可用的屏幕尺寸，此解决方案对于主要功能的重要性，请按以下方式开始qApp->desktop()->availableGeometry();

main.cpp中：

QApplication app(argc, argv);
