这个原因是因为 设计界面对应的 ui_xx.h文件未更新造成的(原因:比如我们工程从一台机器复制到另一台机器,有可能造成该文件不再更新了)(在我们的main.cpp同级目录那个ui_xx.h,而不是debug文件夹内那个ui_xx.h)。我们需要再我们的源码目录删除它,然后执行qmake,就会再次生成它,即更新了它,那我们以后添加控件,都...

因为 text() 不是类 QTextBrowert 的成员函数，不论是Qt4 还是 Qt5。。text()是类Line Edit 的成员函数，所以你不要用 QTextBrowert 用 Line Edit 就可以了。。。
On the 1.6.4 and 1.6.5 versions of the Arduino IDE the String class says to have no member named c_str. I expected this function to work as it does on these softwares when I'm compiling the code to an Arduino Lilypad. This is the part of the code that it happened and the error...
