qt 5.x 学习笔记 (2)
先来放一波过程中用到的资料和官方文档好了。
Standard Dialogs Example qt 5.8
更新的部分还是放在最前面好了。。。
convert from QString to char *的时候有个坑。。。
In order to convert a QString to a char*, then you first need to get a latin1 representation of the string by calling toLatin1() on it which will return a QByteArray. Then call data() on the QByteArray to get a pointer to the data stored in the byte array. See the documentation: See the following example for a demonstration:
举个栗子。。。。
1int main(int argc, char **argv)
2{
3 QApplication app(argc, argv);
4 QString str1 = "Test";
5 QByteArray ba = str1.toLatin1();
6 const char *c_str2 = ba.data();
7 printf("str2: %s", c_str2);
8 return app.exec();
9}
**Note that it is necessary to store the bytearray before you call data() on it, a call like the following const char *c_str2 = str2.toLatin1().data(); will make the application crash as the QByteArray has not been stored and hence no longer exists.**
目前基本框架出来了。。。
可以打开一个文件。。加密。。保存。。。
加密算法部分暂时用倒序输出代替。。。
界面布局还没搞。。。一些提示之类的还没搞。。。。。。。。
接下来要做的。。。大概就是把des写进去了。。。
放一波代码好了。。。

记录一些坑？（其实也不算坑。。。
目前我的做法是有一个全局的QString。。。
我是打算直接拆分包装这个QString。。。每8位。。。
然后QString的[] operator得到的是QCharRef类型。。。。
QString之前有的toAscii()被移除了。。。。
qt 5.2以后的方法叫:toLatin1()
