什么是QtWidget？

Qt帮助文档如此解释&＃xff1a;

The user interface contains visual elements that are called widgets in Qt. Examples of widgets are text edits, scroll bars,
labels, and radio buttons. A widget can also be a container for other widgets; a dialog or a main application window, for
example.

简而言之&＃xff0c;widget&＃xff08;译名&＃xff1a;部件&＃xff09;就是包含可视化元素的用户接口&＃xff0c;如编辑框&＃xff0c;按钮&＃xff0c;标签等等。一些部件如对话框、主窗口等可以容纳其他部件。
