正如你所看到的 - 我不知道它爲什麼不能工作。QGLWidget在Mac OS X下無法正常工作Lion
當程序運行時，會是這樣的：
我使用的MacPorts從QT4-MAC（v4.8.2）。看來這個軟件包是預先編譯好的。
而這裏的源：
main.cpp中：
#include <iostream>
#include <QApplication>
#include "GLPlayerWindow.hpp"
int main(int argc, char *argv[])
{
QApplication app(argc, argv);
GLPlayerWindow window;
window.show();
window.resize(800, 600);
return app.exec();
}
GLPlayerWindow.hpp：
#ifndef __GLPLAYERWINDOW__HPP__DEFINED__
#define __GLPLAYERWINDOW__HPP__DEFINED__
#include <string>
#include <QGLWidget>
#include <QMouseEvent>
#include <QKeyEvent>
#include <QTimer>
#include <SimpleAV_SDL.h>
class GLPlayerWindow : public QGLWidget
{
Q_OBJECT
public:
GLPlayerWindow(QWidget *parent = NULL);
~GLPlayerWindow();
protected slots:
void paintGL();
protected:
void initializeGL();
void resizeGL(int w, int h);
void keyPressEvent(QKeyEvent *event);
};
#endif
GLPlayerWindow.cpp：
#include <iostream>
#include "GLPlayerWindow.hpp"
#include <GL/glu.h>
GLPlayerWindow::GLPlayerWindow(QWidget *parent)
: QGLWidget(parent) {
setMouseTracking(true);
}
GLPlayerWindow::~GLPlayerWindow() {
}
void GLPlayerWindow::initializeGL() {
glDisable(GL_DEPTH_TEST);
glDisable(GL_COLOR_MATERIAL);
glEnable(GL_TEXTURE_2D);
glEnable(GL_BLEND);
glEnable(GL_POLYGON_SMOOTH);
glBlendFunc(GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA);
glClearColor(1.0f, 0.0f, 0.0f, 0);
}
void GLPlayerWindow::resizeGL(int w, int h) {
glViewport(0, 0, w, h);
glMatrixMode(GL_PROJECTION);
glLoadIdentity();
gluOrtho2D(0, w, 0, h); // set origin to top left corner
glMatrixMode(GL_MODELVIEW);
glLoadIdentity();
}
void GLPlayerWindow::paintGL() {
glClear(GL_COLOR_BUFFER_BIT);
return;
}
void GLPlayerWindow::keyPressEvent(QKeyEvent* event) {
}
而且的.pro文件：
