1.建立一个QWidget 工程
-
修改 .pro 文件
添加了两句, 后面可生成两个 xxx.ts
- 编写代码, 对需要转换成国际文字的内容全用
QLabel* pTestLabel;
pTestLabel = new QLabel;
pTestLabel->setText(tr("这里的显示的文字会转换"));
4.生成 xxx.ts文件
我的项目会生成两个 ***.ts
-
***.ts去转换成 ***.qm
打开 linguist,
这东西在/opt/Qt.x.x.x/Qt.x.x.x/gcc_64/bin里面(windos系统,直接在"开始"找qt就有了)
保存生成 ***.qm文件
6.加载 ***.qm
QTranslator pTranslate = new QTranslator(this);
pTranslate->load("执行文件,当前目录下的 ***.qm");
- 安装翻译
qApp->installTranslator(pTranslate);
步骤3.(重新执行一遍,Text的内容就会转到对应 ***.qm指定的文字)
pTestLabel->setText(tr("这里的显示的文字会转换"));
**如果你是有ui的.
直接ui->retranslateUi(this)一键把你的ui里面的文字重新设置一遍,这个操作你也可以自己写个函数封装
Demo:
main.cpp
#include "widget.h"
#include <QApplication>
#include "translatewidget.h"
int main(int argc, char *argv[])
{
QApplication a(argc, argv);
Widget w;
// TranslateWidget w;
w.show();
return a.exec();
}
