Qt Layout Managers

Layout Hierarchy

Qt lays out widgets using layout objects attached to containers. Never call setGeometry() manually — use layouts.

QWidget (parent)
└── QVBoxLayout (attached via setLayout or constructor arg)
    ├── QLabel
    ├── QHBoxLayout (nested)
    │   ├── QPushButton
    │   └── QPushButton
    └── QTextEdit
