/** \defgroup commands Command Framework
\ingroup GUI
* \section Overview
* In GUI applications many commands can be invoked via a menu item, a toolbar button or an accelerator key. The answer of Qt to master this
* challenge is the class \a QAction. A QAction object can be added to a popup menu or a toolbar and keep the state of the menu item and
* the toolbar button synchronized.
*
* For example, if the user clicks the menu item of a toggle action then the toolbar button gets also pressed
* and vice versa. For more details refer to your Qt documentation.
*
* \section Drawbacks
* Since QAction inherits QObject and emits the \a triggered() signal or \a toggled() signal for toggle actions it is very convenient to connect
* these signals e.g. with slots of your MainWindow class. But this means that for every action an appropriate slot of MainWindow is necessary
* and leads to an inflated MainWindow class. Furthermore, it's simply impossible to provide plugins that may also need special slots -- without
* changing the MainWindow class.
*
* \section wayout Way out
* To solve these problems we have introduced the command framework to decouple QAction and MainWindow. The base classes of the framework are
* \a Gui::CommandBase and \a Gui::Action that represent the link between Qt's QAction world and the FreeCAD's command world.
*
* The Action class holds a pointer to QAction and CommandBase and acts as a mediator and -- to save memory -- that gets created
* (@ref Gui::CommandBase::createAction()) not before it is added (@ref Gui::Command::addTo()) to a menu or toolbar.
*
* Now, the implementation of the slots of MainWindow can be done in the method \a activated() of subclasses of Command instead.
*
* For example, the implementation of the "Open file" command can be done as follows.
* \code
* class OpenCommand : public Command
* {
* public:
* OpenCommand() : Command("Std_Open")
* {
* // set up menu text, status tip, ...
* sMenuText = "&Open";
* sToolTipText = "Open a file";
* sWhatsThis = "Open a file";
* sStatusTip = "Open a file";
* sPixmap = "Open"; // name of a registered pixmap
* sAccel = "Shift+P"; // or "P" or "P, L" or "Ctrl+X, Ctrl+C" for a sequence
* }
* protected:
* void activated(int)
* {
* QString filter ... // make a filter of all supported file formats
* QStringList FileList = QFileDialog::getOpenFileNames( filter,QString::null, getMainWindow() );
* for ( QStringList::Iterator it = FileList.begin(); it != FileList.end(); ++it ) {
* getGuiApplication()->open((*it).latin1());
* }
* }
* };
* \endcode
* An instance of \a OpenCommand must be created and added to the \ref Gui::CommandManager to make the class known to FreeCAD.
* To see how menus and toolbars can be built go to the @ref workbench.
*
* @see Gui::Command, Gui::CommandManager
