For instance, a user may want to paste the contents of the clipboard or scroll down a document or quit the application. These are all actions -- events that the user causes to happen. The TDEAction class allows the developer to deal with these actions in an easy and intuitive manner. Specifically, the TDEAction class encapsulated the various attributes to an event/action. For instance, an action might have an icon that goes along with it (a clipboard for a "paste" action or scissors for a "cut" action). The action might have some text to describe the action. It will certainly have a method or function that actually executes the action! All these attributes are contained within the TDEAction object. The advantage of dealing with Actions is that you can manipulate the Action without regard to the GUI representation of it. For instance, in the "normal" way of dealing with actions like "cut", you would manually insert a item for Cut into a menu and a button into a toolbar. If you want to disable the cut action for a moment (maybe nothing is selected), you would have to hunt down the pointer to the menu item and the toolbar button and disable both individually. Setting the menu item and toolbar item up uses very similar code - but has to be done twice! With the Action concept, you simply "plug" the Action into whatever GUI element you want. The TDEAction class will then take care of correctly defining the menu item (with icons, accelerators, text, etc) or toolbar button.. or whatever. From then on, if you manipulate the Action at all, the effect will propogate through all GUI representations of it. Back to the "cut" example: if you want to disable the Cut Action, you would simply do 'cutAction.setEnabled(false)' and the menuitem and button would instantly be disabled! This is the biggest advantage to the Action concept -- there is a one-to-one relationship between the "real" action and all GUI representations of it. TDEAction emits the activated() signal if the user activated the corresponding GUI element ( menu item, toolbar button, etc. ) If you are in the situation of wanting to map the activated() signal of multiple action objects to one slot, with a special argument bound to each action, then you might consider using TQSignalMapper . A tiny example:
 TQSignalMapper desktopNumberMapper = new TQSignalMapper( this );
 connect( desktopNumberMapper, SIGNAL("mapped( int )"),
          this, SLOT("moveWindowToDesktop( int )") );
 for ( uint i = 0; i < numberOfDesktops; ++i ) {
     TDEAction desktopAction = new TDEAction( i18n( "Move Window to Desktop %i" ).arg( i ), ... );
     connect( desktopAction, SIGNAL("activated()"), desktopNumberMapper, SLOT("map()") );
     desktopNumberMapper.setMapping( desktopAction, i );
 }
 
  • General Usage:
  • The steps to using actions are roughly as follows
  • Decide which attributes you want to associate with a given action (icons, text, keyboard shortcut, etc)
  • Create the action using TDEAction (or derived or super class).
  • "Plug" the Action into whatever GUI element you want. Typically, this will be a menu or toolbar.
  • Detailed Example:
  • Here is an example of enabling a "New [document]" action
     TDEAction newAct = new TDEAction(i18n("&New"), "filenew",
                                   TDEStdAccel.shortcut(TDEStdAccel.New),
                                   this, SLOT("fileNew()"),
                                   actionCollection(), "new");
     
    This line creates our action. It says that wherever this action is displayed, it will use "&New" as the text, the standard icon, and the standard shortcut. It further says that whenever this action is invoked, it will use the fileNew() slot to execute it.
     TQPopupMenu file = new TQPopupMenu;
     newAct.plug(file);
     
    That just inserted the action into the File menu. The point is, it's not important in which menu it is: all manipulation of the item is done through the newAct object.
     newAct.plug(toolBar());
     
    And this inserted the Action into the main toolbar as a button. That's it! If you want to disable that action sometime later, you can do so with
     newAct.setEnabled(false)
     
    and both the menuitem in File and the toolbar button will instantly be disabled. Do not delete a TDEAction object without unplugging it from all its containers. The simplest way to do that is to use the unplugAll() as in the following example:
     newAct.unplugAll();
     delete newAct;
     
    Normally you will not need to do this as TDEActionCollection manages everything for you. Note: if you are using a "standard" action like "new", "paste", "quit", or any other action described in the KDE UI Standards, please use the methods in the KStdAction class rather than defining your own.
  • Usage Within the XML Framework:
  • If you are using TDEAction within the context of the XML menu and toolbar building framework, then there are a few tiny changes. The first is that you must insert your new action into an action collection. The action collection (a TDEActionCollection) is, logically enough, a central collection of all of the actions defined in your application. The XML UI framework code in KXMLGUI classes needs access to this collection in order to build up the GUI (it's how the builder code knows which actions are valid and which aren't). Also, if you use the XML builder framework, then you do not ever have to plug your actions into containers manually. The framework does that for you.
