QT (.cpp file to the application)

1, first create a file .cpp below a generating application in a disk (F disc)

#include <QPushButton>
#include <QHBoxLayout>
#include <QVBoxLayout>
#include <QWidget>

int main(int argc , char *argv[])
{
	QApplication app(argc , argv);
	
	QLabel *infoLabel = new QLabel;		//创建标签对象
	QLabel *openLabel = new QLabel;
	QLineEdit *cmdLineEdit = new QLineEdit;		//创建文本编辑框对象
	QPushButton *commitButton = new QPushButton;	//创建按钮对象
	QPushButton *cancelBotton = new QPushButton;
	QPushButton *browseButton = new QPushButton;
	
	infoLabel->setText("input your cmd ..");
	openLabel->setText("open");
	commitButton->setText("commit");
	cancelBotton->setText("cancel");
	browseButton->setText("browse");
	
	QHBoxLayout *cmdLayout = new QHBoxLayout;			//水平布局对象
	cmdLayout->addWidget(openLabel);
	cmdLayout->addWidget(cmdLineEdit);
	
	QHBoxLayout *buttonLayout = new QHBoxLayout;
	buttonLayout->addWidget(commitButton);
	buttonLayout->addWidget(cancelBotton);
	buttonLayout->addWidget(browseButton);
	
	QVBoxLayout *mainLayout = new QVBoxLayout;			//全局的垂直布局
	mainLayout->addWidget(infoLabel);
	mainLayout->addLayout(cmdLayout);						//注意是addLayout() 在已经水平的一个组合
	mainLayout->addLayout(buttonLayout);
	
	QWidget *w = new QWidget;
	w->setLayout(mainLayout);
	w->show();
	
	return app.exec();
}

2, open the Qt command prompt
(1), f: // into the F drive
(2), cd cd path F //: \ QMAKE \ qmake
(3), qmake -project // generating projects
(4), use Notepad to open qmake.pro add content to the GUI Widgets = + QT
(5), qmake // generate the makefile
(6), mingw32-make // compiler generates several files to find the release folder can click on the application

Within If Advanced system settings computer properties -> Advanced -> no path QT installed within pash path within the environment variables (system and user variables), it is necessary -> New -> Add to add into the QT path can be a
