In this work, I will create a very simple Qt Application with a dummy button (inherite from QPushButton), start from Empty Qt Project.
Start QtCreator, click File -> New project or Project... on the top menu, Select Empty Qt Project under Project.
Fill in the Name (MyFirstWidget here) of your project and browse to the locate where to create your project on, and click Next
Then Finish.
Because what you created is a Empty Qt Project, only a dummy MyFirstWidget.pro will be created.
Create a main.cpp, click File -> New project or Project..., select C++ Source File under C++, and Click OK.
Fill in the Name of the source file, main, click Next, and then Finish.
Insert the following code in main.cpp
#include <QtGui>
int main(int argc, char *argv[])
{
QApplication app(argc, argv);
QWidget window;
window.resize(320, 240);
window.setWindowTitle("My First Widget");
window.show();
QPushButton *button = new QPushButton("Hello", &window);
button->move(100, 100);
button->show();
return app.exec();
}
Save All and Click the Run button (Green Arrow).
Up to now, we created a Qt application, with a no function button.
Nokia today released version 4.6.1 of Qt on 19 January 2010: the cross-platform application and UI framework, and version 1.3.1 of Qt Creator: the cross-platform IDE for Qt development . Qt 4.6.1 brings improvements to developers targeting Symbian, most notably introducing a binary compatibility guarantee as announced with the Qt 4.6.0 release in December 2009. Both releases introduce bug fixes and optimizations made since the Qt 4.6.0 and Qt Creator 1.3.0 releases.
