我有几种方法可以在一些QT事件上做出React。在其中一种方法中，我在OpenGL小部件中绘制点。在另一个例子中，我想以某个Angular 旋转它们。这一场景是飞机场景。以下是这些方法：

# include "GLMap.h"

GLMap::GLMap{}

void GLMap::initializeGL(){
    glClearColor(r,g,b,alpha);
}

void GLMap::resizeGL(int w, int h){
    glMatrixMode(GL_MODELVIEW);
    glLoadIdentity();
    glViewport(0,0,(GLint)w,(GLint)h);
    glOrtho(0,1024,720,0,-1,1);
    glPushMatrix();
}

void GLMap::paintGL(){
    glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);
    if(pointsVec.size()!=0){
         glPushMatrix();
         foreach(QPoint pt, pointsVec){
              draw(pt.x(),pt.y(),GL_POINTS);
         }

         glPopMatrix();
    }
}

void GLMap::draw(int x, int y, GLenum type){
     glPointsSize(5);
     glBegin(type)
         glColor3f(0,0,0);
         glVertex2i(x,y);
    glEnd();
 }

 void GLMap::mouseDoubleClickEvent(QMouseEvent *event){
    cutPt.setX(event->x());
    curPt.setY(event->y());
    pointsVec.push_back(curPt);
    repaint();
 }

 void GLMap::wheelEvent(QWheelEvent *event){ 
   anlge+=0.9;
   if(ang le>360.0){
        angle = 0.0f;
   }

   glPopMatrix();
   glLoadIdentity();
   glRotatef(angle,0.0,0.0,1.0f);
   glPushMatrix();
 }

轮换不想完成。我的代码中有什么错误。
