newprojectwindow.cpp

Qt平台下使用,C++语言所实现的,球体位置变化,并相应的视角跟踪以及变换.对于学习,OpenGL的glLookAt很有帮助.

#include "newprojectwindow.h"


NewProjectWindow::NewProjectWindow( QWidget* parent, const char* name, WFlags f )
	: QMainWindow( parent, name, f )
{
	setCaption("NewProject");
	

	// Add your code

	gl = new GLWidget(this);

	timer = new QTimer( this );
    connect( timer, SIGNAL(timeout()), gl,SLOT(animate()) );
    timer->start( 50 );

	connect(this,SIGNAL(press(QKeyEvent *)),gl,SLOT(press(QKeyEvent *))); 

}

void NewProjectWindow::resizeEvent(QResizeEvent *)
{
	gl->resize (width(), height() );
}

void NewProjectWindow::keyPressEvent(QKeyEvent *e)
{
	emit press(e);
}
