Using lupdate tool

I'm using Qt 4.7.1 on window vista.I want to make my qt application to 开发者_StackOverflow社区be translatable. How can I use the Lupdate tool to generate .ts files? From where I can run it from Qt creator or Qt linguist?

C:\Qt\4.7.4\bin

or where ever your QT files are found, just check the bin folder.
