# uic(1)

Qt user interface compiler

## NAME

uic - Qt user interface compiler

## SYNOPSIS

**uic** \[options\] file

## DESCRIPTION

This page documents the **User Interface Compiler** for the Qt GUI application framework. The **uic** reads a user interface definition file in XML as generated by the Qt Designer and creates corresponding C++ header or source files.

Generate declaration:\
 	***uic  \[options\]**  \<file\>*\

Generate implementation:\
 	***uic  \[options\] -impl** \<headerfile\> \<file\>*\
\
         *\<headerfile\>*:    name of the declaration file\

For convenience,  **uic** can also generate declaration or implementation stubs for subclasses.

Generate subclass declaration:\
 	***uic  \[options\] -subdecl** \<classname\> \<headerfile\> \<file\>*\
\
         *\<classname\>*:     name of the subclass to generate\
\
         *\<headerfile\>*:    declaration file of the baseclass

Generate subclass implementation:\
 	***uic  \[options\] -subimpl** \<classname\> \<headerfile\> \<file\>*\
\
         *\<classname\>*:     name of the subclass to generate\
\
         *\<headerfile\>*:    declaration file of the subclass

## GENERAL OPTIONS

- *-o file*

  Write output to *file* rather than to stdout.

- *-tr func*

  Use  *func(...)* rather than tr(...) for i18n.

## USAGE

**uic** is almost always invoked by [**make**(1)](/make/1.md), not by hand.

Here are useful makefile rules if you only use GNU make:

%.h: %.ui\
\
         uic $\< -o $@\
 %.cpp: %.ui\
\
         uic -impl $\*.h $\< -o $@

If you want to write portably, you can use individual rules of the following form:

NAME.h: NAME.ui\
\
         uic $\< -o $@\
 NAME.cpp: NAME.ui\
\
         uic -impl $\*.h $\< -o $@

You must also remember to add *NAME.cpp* to your SOURCES (substitute your favorite name) variable and *NAME.o* to your OBJECTS variable.

(While we prefer to name our C++ source files .cpp, the **uic** doesn't know that, so you can use .C, .cc, .CC, .cxx or even .c++ if you prefer.)
