opengl嵌入pyqt5编译的分割窗口中
向大部分商业仿真软件一样，使用opengl显示三维模型，首先需要将opengl的窗口嵌入到pyqt5编译的界面中
下面是一个小例子：
- from PyQt5.QtGui import *
- from PyQt5.QtWidgets import *
- from PyQt5.QtCore import *
- from PyQt5.QtOpenGL import QGLWidget
- import sys
- from OpenGL.GL import *
-
- class MainWindow(QMainWindow):
- """docstring for Mainwindow"""
- def __init__(self, parent = None):
- super(MainWindow,self).__init__(parent)
- self.basic()
- splitter_main = self.split_()
- self.setCentralWidget(splitter_main)
-
- #窗口基础属性
- def basic(self):
- #设置标题，大小，图标
- self.setWindowTitle("GT")
- self.resize(1100,650)
- self.setWindowIcon(QIcon("./image/Gt.png"))
- #居中显示
- screen = QDesktopWidget().geometry()
- self_size = self.geometry()
- self.move((screen.width() - self_size.width())/2,(screen.height() - self_size.height())/2)
-
- #分割窗口
- def split_(self):
- splitter = QSplitter(Qt.Vertical)
- s = OpenGLWidget() #将opengl例子嵌入GUI
- splitter.addWidget(s)
- testedit = QTextEdit()
- splitter.addWidget(testedit)
- splitter.setStretchFactor(0,3)
- splitter.setStretchFactor(1,2)
- splitter_main = QSplitter(Qt.Horizontal)
- textedit_main = QTextEdit()
- splitter_main.addWidget(textedit_main)
- splitter_main.addWidget(splitter)
- splitter_main.setStretchFactor(0,1)
- splitter_main.setStretchFactor(1,4)
- return splitter_main
-
- class OpenGLWidget(QGLWidget):
- def initializeGL(self):
- glClearColor(1,0,0,1)
- glEnable(GL_DEPTH_TEST)
- glEnable(GL_LIGHT0)
- glEnable(GL_LIGHTING)
- glColorMaterial(GL_FRONT_AND_BACK, GL_AMBIENT_AND_DIFFUSE)
- glEnable(GL_COLOR_MATERIAL)
-
- def paintGL(self):
- glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT)
- glBegin(GL_TRIANGLES)
- glColor3f(1.0, 0.0, 0.0)
- glVertex3f(-0.5, -0.5, 0)
- glColor3f(0.0, 1.0, 0.0)
- glVertex3f( 0.5, -0.5, 0)
- glColor3f(0.0, 0.0, 1.0)
- glVertex3f( 0.0, 0.5, 0)
- glEnd()
-
-
- if __name__ == "__main__":
- app = QApplication(sys.argv)
- win = MainWindow()
- win.show()
- sys.exit(app.exec_())
运行便可以看到，opengl成功嵌入到了pyqt5的分割窗口中~
也可以将QGLWidget的类写在另一个文件中，然后再次导入文件实现
