    Default QPainterPath cannot work with OpenGL?

    For a simple OpenGL code:
    Qt Code:
    1. void display(void)
    2. {
    3. glClear(GL_COLOR_BUFFER_BIT);
    4.  
    5. glColor3f (0.0, 1.0, 0.0);
    6. glPushMatrix();
    7. glRotatef(-rotAngle, 0.0, 0.0, 0.1);
    8. glBegin (GL_LINES);
    9. glVertex2f (-0.5, 0.5);
    10. glVertex2f (0.5, -0.5);
    11. glEnd ();
    12. glPopMatrix();
    13.  
    14. glColor3f (0.0, 0.0, 1.0);
    15. glPushMatrix();
    16. glRotatef(rotAngle, 0.0, 0.0, 0.1);
    17. glBegin (GL_LINES);
    18. glVertex2f (0.5, 0.5);
    19. glVertex2f (-0.5, -0.5);
    20. glEnd ();
    21. glPopMatrix();
    22.  
    23. glFlush();
    24. }
    To copy to clipboard, switch view to plain text mode 

    I mean, whether I could add the lines drawn by OpenGL as a path defined by QPainterPath ?

    Then I could operate using the "path" more easily.

    Thanks a lot

    Default Re: QPainterPath cannot work with OpenGL?

    I think what you really want is a vector (e.g. a QVector) of coordinates and not a painter path.
    Your biological and technological distinctiveness will be added to our own. Resistance is futile.

    Please ask Qt related questions on the forum and not using private messages or visitor messages.
