This class basically offers two things: \list \i Dynamically creating widgets from \link designer-manual.book Qt Designer\endlink user interface description files. You can do this using the static function TQWidgetFactory::create(). This function also performs signal and slot connections, tab ordering, etc., as defined in the .ui file, and returns the top-level widget in the .ui file. After creating the widget you can use TQObject::child() and TQObject::queryList() to access child widgets of this returned widget. \i Adding additional widget factories to be able to create custom widgets. See createWidget() for details. \endlist This class is not included in the Qt library itself. To use it you must link against \c libqui.so (Unix) or \c qui.lib (Windows), which is built into \c INSTALL/lib if you built \e{Qt Designer} (\c INSTALL is the directory where Qt is installed ). See the "Creating Dynamic Dialogs from .ui Files" section of the \link designer-manual.book Qt Designer manual\endlink for an example. See also the \l{QWidgetPlugin} class and the \link plugins-howto.html Plugins documentation\endlink. */ /*!

This function also performs signal and slot connections, tab ordering, etc., as described in the .ui file. In \e{Qt Designer} it is possible to add custom slots to a form and connect to them. If you want these connections to be made, you must create a class derived from TQObject, which implements all these slots. Then pass an instance of the object as \a connector to this function. If you do this, the connections to the custom slots will be done using the \a connector as slot. If something fails, 0 is returned. The ownership of the returned widget is passed to the caller. */ TQWidget *TQWidgetFactory::create( const TQString &uiFile, TQObject *connector, TQWidget *parent, const char *name ) { setupPluginDir(); TQFile f( uiFile ); bool failed = FALSE; if ( !f.open( IO_ReadOnly ) ) failed = TRUE; if ( failed && qApp->type() == TQApplication::Tty ) { // for QSA: If we have no GUI, we have no form definition // files, but just the code.
