QT学习ubuntu qt + desktop

环境搭建

ubuntu 安装QT 遇到kit 选择不了

通过sudo apt-get install qt5-default去安装SDK的时候报错：

Package qt5-default is not available, but is referred to by another package. This may mean that the package is missing, has been obsoleted, or is only available from another source E: Package 'qt5-default' has no installation candidate

可以执行

sudo apt-get install qtbase5-dev qtchooser qt5-qmake qtbase5-dev-tools qtcreator

配置Kit: 看下对应的编译器是否自动找到了，没找到去设置一下路径

程序结构介绍

QpushButton

可以在帮助文档中搜索，发现它的父类和子类。父类需要包含到头文件中
