    Default QTreeList.. Everything is ok but??

    All my code is correct. It compiles the program and it also works but
    I can none of my frames on the panel. I can see only an empty panel.

    Is there any incorrect thing in the code?? or may ı forget any "show " or "set" words??
    I couldn't see my error. Please help me.
