Window Geometry[窗口几何尺寸]

Window Geometry

QWidget provides several functions that deal with a widget's geometry. Some of these functions operate on the pure client area (i.e. the window excluding the window frame), others include the window frame. The differentiation is done in a way that covers the most common usage transparently.

• Including the window frame: x(), y(), frameGeometry(), pos(), and move().
• Excluding the window frame: geometry(), width(), height(), rect(), and size().

Note that the distinction only matters for decorated top-level widgets. For all child widgets, the frame geometry is equal to the widget's client geometry.
