Detailed Description

A size grip sits in the bottom right corner of a window, often in a status bar. Dragging it resizes the window that contains it, within the minimum and maximum size of the window:

auto *grip = new QSizeGrip(window);
layout->addWidget(grip, 0, Qt::AlignBottom | Qt::AlignRight);

See also QStatusBar.

Differences from Qt

The grip resizes the window itself rather than asking the window manager to, and it is always in the bottom right corner: it does not hide when the window is maximized or move for right-to-left layouts.
