    <p>When you are developing without the Qt Creator IDE, unless the IDE includes by itself some automatic utilities, you must edit manually the .pro configuration file.</p> <p>The generated .pro file is a skeleton file which YOU must fill in with the libraries that you need, then the qmake system figures out the other dependencies and compiles your project. It is a essentially a much better version of pkg-config of gtk + Makefiles.</p> <p>When you add more source and resource files to your project then manually you must add them to the .pro file.</p> <p>Example:</p> <pre><code>QT += core gui TARGET = qtcp1 TEMPLATE = app SOURCES += main.cpp\ mainwindow.cpp \ miwidget1.cpp \ lcdrange.cpp HEADERS += mainwindow.h \ miwidget1.h \ lcdrange.h FORMS += mainwindow.u </code></pre> <p>Alternately, you can issue <code>qmake -project</code> over and over again, but this can cause some unforseen accidents, since it includes everything that is in the current directory at the time, including the pre-processed files for conversion to standard C++ from QT dialect. This intermediate files must be erased (cleaned), before the remaking the project and the next make or can lead to tricky problems.</p> <p>Using the official and free QT Creator IDE takes away most of this burden by adding automatically the new data to the .pro file and cleaning loose ends. Some other IDEs like Code::BLocks and Codelite provide some facilities for QT, but not to the level of QT creator. Some prefer to edit the .pro themselves for custom reasons, other like more other styles of IDEs, like Eclipse.</p> <p>You should test the waters and decide by yourself what fits best to your needs.</p> <p>ReEdited, to clarify a few things.</p>

    2. COI don't know what you define as proper, the QtCreator IDE gives you point and click facilities, add new sources files automatically, includes various code versioning tools, a built-in forms creator which also automatically adds the result to the .pro file, adding external libraries is a right click-> wizard to add libraries. I doubt there is a build system in the world that can satisfy you if this can't. You should give a more clear example of what you consider "proper".

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
