除了覆盖paintGl方法之外,您还必须使用pyopengl库以及GLUT模块(在您的情况下),在以下部分中显示示例:
You must use the pyopengl library, and for your case the GLUT module, in addition to overriding the paintGl method, I show an example in the following part:
import sys
from PyQt5.QtWidgets import *
from PyQt5.QtGui import *
from PyQt5.QtCore import *
from PyQt5.uic import *
from OpenGL.GL import *
from OpenGL.GLUT import *
from OpenGL.GLU import *
class mainWindow(QMainWindow):
def __init__(self, *args):
super(mainWindow, self).__init__(*args)
loadUi('minimal.ui', self)
def setupUI(self):
self.openGLWidget.initializeGL()
self.openGLWidget.resizeGL(651,551)
self.openGLWidget.paintGL = self.paintGL
timer = QTimer(self)
timer.timeout.connect(self.openGLWidget.update)
timer.start(1000)
def paintGL(self):
glClear(GL_COLOR_BUFFER_BIT)
glColor3f(1,0,0);
glBegin(GL_TRIANGLES);
glVertex3f(-0.5,-0.5,0);
glVertex3f(0.5,-0.5,0);
glVertex3f(0.0,0.5,0);
glEnd()
gluPerspective(45, 651/551, 0.1, 50.0)
glTranslatef(0.0,0.0, -5)
app = QApplication(sys.argv)
window = mainWindow()
window.setupUI()
window.show()
sys.exit(app.exec_())
