User Interface Compiler (uic)#

This page documents the User Interface Compiler for the Qt Widgets module. The uic reads an XML format user interface definition (.ui) file as generated by Qt Designer and creates a corresponding C++ header file.

The following table lists the command-line options recognized by uic.



-h, --help

If you use qmake, uic will be invoked automatically for header files.

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

ui_%.h: %.ui
        uic $< -o $@

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

ui_foo.h: foo.ui
        uic $< -o $@

You must also remember to add ui_foo.h to your HEADERS (substitute your favorite name).
