Detailed Description
Class to encapsulate user-driven action or event.
The TDEAction class (and derived and super classes) provides a way to easily encapsulate a "real" user-selected action or event in your program.
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:
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
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.
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.
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
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:
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.

◆ TDEAction() [1/11]
TDEAction::TDEAction | ( | const TQString & | text, |
const TDEShortcut & | cut, | ||
const TQObject * | receiver, | ||
const char * | slot, | ||
TDEActionCollection * | parent, | ||
const char * | name | ||
) |
Constructs an action with text, potential keyboard shortcut, and a slot to call when this action is invoked by the user.
If you do not want or have a keyboard shortcut, set the cut
param to 0.
This is the most common TDEAction used when you do not have a corresponding icon (note that it won't appear in the current version of the "Edit ToolBar" dialog, because an action needs an icon to be plugged in a toolbar...).
- Parameters
-
text The text that will be displayed. cut The corresponding keyboard shortcut. receiver The slot's parent. slot The slot to invoke to execute this action. parent This action's parent. name An internal name for this action.
Definition at line 123 of file tdeaction.cpp.

const char * | name | ||
) |
Constructs an action with text, icon, potential keyboard shortcut, and a slot to call when this action is invoked by the user.
If you do not want or have a keyboard shortcut, set the cut
param to 0.
This is the other common TDEAction used. Use it when you do
have a corresponding icon.
- Parameters
-

const char * | name | ||
) |
Constructs an action with text, icon, potential keyboard shortcut, and a slot to call when this action is invoked by the user.
The icon is loaded on demand later based on where it is plugged in.

param to 0.
This is the other common TDEAction used. Use it when you do
have a corresponding icon.
- Parameters
-
text The text that will be displayed. pix The icon to display. cut The corresponding keyboard shortcut (shortcut). receiver The slot's parent. slot The slot to invoke to execute this action. parent This action's parent. name An internal name for this action.

◆ activate
|
virtualslot |

Definition at line 1104 of file tdeaction.cpp.
◆ activated [1/2]
|
signal |
Emitted when this action is activated.
◆ activated [2/2]
|
signal |
This signal allows to know the reason why an action was activated: whether it was due to a toolbar button, popupmenu, keyboard accel, or programmatically.
In the first two cases, it also allows to know which mouse button was used (Left or Middle), and whether keyboard modifiers were pressed (e.g. CTRL).
Note that this signal is emitted before the normal activated() signal. Yes, BOTH signals are always emitted, so that connecting to activated() still works. Applications which care about reason and state can either ignore the activated() signal for a given action and react to this one instead, or store the reason and state until the activated() signal is emitted.

◆ getToolButtonID()
|
static |
How it works.
Generate a toolbar button id. Made public for reimplementations.
TDEActionCollection is an organizing container for TDEActions. TDEActionCollection keeps track of the information necessary to handle configuration and shortcuts.
Focus Widget pointer: This is the widget which is the focus for action shortcuts. It is set either by passing a TQWidget* to the TDEActionCollection constructor or by calling setWidget() if the widget wasn't known when the object was initially constructed (as in KXMLGUIClient and KParts::PartBase)
Shortcuts: An action's shortcut will not not be connected unless a focus widget has been specified in TDEActionCollection.
XML Filename: This is used to save user-modified settings back to the *ui.rc file. It is set by KXMLGUIFactory.

Sets the tooltip text for the action.
This will be used as a tooltip for a toolbar button, as a statusbar help-text for a menu item, and it also appears in the toolbar editor, to describe the action.
For the tooltip to show up on the statusbar you will need to connect a couple of the actionclass signals to the toolbar. The easiest way of doing this is in your main window class, when you create a statusbar. See the TDEActionCollection class for more details.
