qt-编码问题解答

1.qt中子类继承父类重写父类函数的时候可以不用写override关键字

2.想要setGeometry有效，控件就不能在布局里。 如果使用了布局，控件大小有布局自动控制。

3.qwidgets开发下的.ui文件不能手动更改只能在设计器里更改。

3..pro中增加库引用写法实例

win32
{
INCLUDEPATH += 'C:/Program Files (x86)/IVI Foundation/VISA/WinNT/Include'
LIBS+='C:/Program Files (x86)/IVI Foundation/VISA/WinNT/lib/msc/visa32.lib'
}
