It's about time to get ready to learn Qt programming for embedded systems or something like MeeGo?

Intel and Nokia announced MeeGo, which is a combination of the Moblin and Maemo platforms.
As for developing the application, it seems Qt is ( a or the default ?) development framework for MeeGo.

So I tried using Qt Creator for Windows to investigate how difficult or easy to develop the software.

Qt Creator

As usual, I just created very very verrrry simple Qt GUI application.(it's nothing special.)

 I think this software development is not so hard unless I will try to create complex programs.
and I think Qt must be very useful for not only embedded software but also some applications on linux and MacOS as well.

main.cpp

#include "mainwindow.h" #include "qlabel.h" #include "qtextcodec.h" int main(int argc, char *argv[]) { QApplication a(argc, argv); QTextCodec::setCodecForTr(QTextCodec::codecForLocale()); QTextCodec::setCodecForCStrings(QTextCodec::codecForLocale()); MainWindow w; w.setWindowTitle("Qt Application Demo"); w.setMaximumSize(400,260); w.setMinimumSize(400,260); w.resize(400,260); QLabel *lbl = new QLabel(&w); lbl->setFrameStyle(QFrame::Panel | QFrame::Sunken); lbl->setText("<font color=red>Hello World!</font>"); QFont font("Verdana",32,12,false); lbl->setFont(font); lbl->setAlignment(Qt::AlignVCenter | Qt::AlignHCenter); lbl->setGeometry(30,40,340,180); w.show(); return a.exec(); }

mainwindow.cpp

#include "mainwindow.h" #include "ui_mainwindow.h" MainWindow::MainWindow(QWidget *parent) : QMainWindow(parent), ui(new Ui::MainWindow) { ui->setupUi(this); QAction* exitAction = new QAction(tr("終了(&X)"),this); exitAction->setStatusTip("アプリケーションを終了します。"); connect(exitAction,SIGNAL(triggered()),this,SLOT(close())); QMenu* menu = this->menuBar()->addMenu(tr("メニュー(&M)")); menu->addAction(exitAction); } MainWindow::~MainWindow() { delete ui; } void MainWindow::changeEvent(QEvent *e) { QMainWindow::changeEvent(e); switch (e->type()) { case QEvent::LanguageChange: ui->retranslateUi(this); break; default: break; } }
