QT HTML5与菜单栏像真正的程序 [英] QT HTML5 with Menu Bar like real program

问题描述

我正在处理一个QT HTML5应用程序，我想知道如何添加一个顶级菜单，像正常程序（使用默认的文件，工具，帮助... options）。

I'm working on an QT HTML5 application and I was wondering how i could add an top menu just like normal program ( with the default file, tools, help... options ).

我认为我必须改变 html5applicationviewer.cpp （我正在学习这个...）

I think that I've to change something in the html5applicationviewer.cpp, but I've got 0 knowledge of that ( I'm learning this... )

即使你能给我一个正确的方向，我感谢。我已经搜索过，但发现绝对没有关于这个话题（但也许我没有搜索正确...）

Even if you could point me a little bit in the right direction, I'm grateful. I've searched around, but found absolutely nothing about this topic ( but maybe i didn't search right... )

如果你需要更多的信息，请问。

If you need more info, please ask.

推荐答案

将正常的桌面菜单添加到Qt应用程序的最简单的方法是使用 QMainWindow ，它拥有对菜单的良好支持。

Simplest way to add normal "desktop"-style menus to a Qt app is to use QMainWindow which has good support for menus.

这里有一些东西让你开始。首先，我使用Qt Creator（SDK版本5.2.1）创建了默认的HTML5 Qt应用程序。然后我编辑了 main.cpp 并添加了一些行。结果如下，原始行没有注释，所有添加的行都有注释。

Here's something to get you started. First I created the default HTML5 Qt application with Qt Creator (SDK version 5.2.1). Then I edited the main.cpp and added some lines. Result is below, original lines without comment and all added lines with comment.

#include <QApplication>

#include <QMainWindow> // added
#include <QMenuBar> // added
#include <QMenu> // added
#include <QAction> // added

#include "html5applicationviewer.h"

int main(int argc, char *argv[])
{
    QApplication app(argc, argv);

    QMainWindow w; // important, viewer is in stack so w must be before it!

    Html5ApplicationViewer viewer;

    w.setCentralWidget(&viewer); // set viewer as the central widget
    QMenu *fileMenu = w.menuBar()->addMenu("&File"); // create file menu
    QAction *exitAction = fileMenu->addAction("&Exit"); // create exit action
    QObject::connect(exitAction, SIGNAL(triggered()), qApp, SLOT(quit())); // make the action do something

    viewer.setOrientation(Html5ApplicationViewer::ScreenOrientationAuto);
    //viewer.showExpanded(); // will be shown by main window
    viewer.loadFile(QLatin1String("html/index.html"));

    w.show(); // show main window

    return app.exec();
}
