Hi
Its not releated to
https://forum.qt.io/topic/60770/qpainter-changes-the-rendering-of-openglwidgetMaybe you show the code and in which way its not working?
Im not into openGl but many of the others are
so add some more details and im sure someone knows the answer :) -
void Glass::initializeGL() { initializeOpenGLFunctions(); glEnable(GL_BLEND); glBlendFunc(GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA); .... } void Glass::draw_vert_line(int index) { glEnableClientState(GL_COLOR_ARRAY); glPushAttrib(GL_ENABLE_BIT); glLineStipple(1, 0x0101); glEnable(GL_LINE_STIPPLE); glVertexPointer(2, GL_INT, 0, vert_lines[index]); // clear rect glColorPointer(4, GL_FLOAT, 0, color); glDrawArrays(GL_LINES, 0, 2); glPopAttrib(); glDisableClientState(GL_COLOR_ARRAY); }
Line not blended. When I use QGLWidget it is.
