qt_add_lupdate

概要

qt_add_lupdate(target TS_FILES file1.ts [file2.ts ...]
               [SOURCES source1.cpp [sources2.cpp ...]]
               [INCLUDE_DIRECTORIES directory1 [directory2 ...]]
               [NO_GLOBAL_TARGET]
               [OPTIONS ...])

若无版本命令被禁用，使用 qt6_add_lupdate() 代替。它支持如此命令的一组相同自变量。

描述

Creates a target ${target}_lupdate to generate or update Qt Linguist .ts files with lupdate .

参数 target is an existing executable or library target that contains sources with translatable strings.

.ts files must be specified with the argument TS_FILES .

This function is designed to be used in conjunction with qt_add_lrelease . See also the convenience wrapper qt_add_translations .

Sources and Include Directories

默认情况下， qt_add_lupdate extracts the source files and include directories from the given target and passes them to lupdate .

采用 SOURCES one may explicitly specify source files that contain translatable strings. This turns off the automatic extraction of source files from the target.

INCLUDE_DIRECTORIES can be used to explicitly specify include directories. This turns off the automatic extraction of include directories from the target.

选项

可以设置额外 选项 that should be passed when lupdate is invoked. You can find possible options in the lupdate documentation .

Umbrella Target

In addition to the target ${target}_lupdate , an umbrella target update_translations is created. This target will build all ${target}_lupdate targets that were created with qt_add_lupdate .

Pass NO_GLOBAL_TARGET to qt_add_lupdate to prevent this behavior.

The name of this target can be overridden by setting the variable QT_GLOBAL_LUPDATE_TARGET before calling qt_add_lupdate .

范例

Add the targets myapp_lupdate and update_translations for updating the .ts file of an application myapp .

qt_add_lupdate(myapp TS_FILES myapp_de.ts)
