The examples are very complex and I understood them.

can't run in display

You forgot to add the second and the third layouts to the first one.

    gl_layaout[0] = new QGridLayout(parent);
    gl_layaout[1] = new QGridLayout(parent);
    gl_layaout[2] = new QGridLayout(parent);
    
    // add them here
    gl_layaout[0]->addLayout(gl_layaout[1],0,0);
    gl_layaout[0]->addLayout(gl_layaout[2],0,1);

Obviously a layout is not a widget ...

I don't understand what you trying to do with the spacers.

Construct the interface you want in QDesigner and post a screenshot of it here.
I will try to reproduce it with code only.
