了解如何获取Qt小部件的位置，可以使用geometry(), pos(), x(), y()等函数。geometry()返回不包含窗口边框的矩形位置，x(), y()返回包含边框的坐标，pos()返回相对于父组件的位置，width(), height()则不包括窗口边框。注意所有这些函数返回的是相对于其父组件的值。" 123005416,9467809,phpmyadmin安全风险与getshell技巧,"['web安全', '数据库', 'php', 'phpmyadmin漏洞']

To get Qt widget position,we can call function such as:

geometry(),pos(),x(),y(),width(),height()

The difference between geometry() with pos(),x(),y(),width(),height() below:

when we call geometry(),this will return a QRect,it indicates the widget position exclude window frame,but size with them(designed in QtDesigner).

when we call x(),y(),they will return the widget x-coordinate and y-coordinate include window frame.

when we call pos(),this will return the widget position within its parent.

when we call width(),height(),exclude the window frame.

but pay attention:all these functions will return value relative to their parent,so,to QMainWindow,these functions will return its postion relative to the desktop,but to other sub-widgets ,these functions always return the value relative to their parent widget

the diagram below:
