Since the same action must be performed regardless of how the action was invoked, and since the menu and toolbar should be kept in sync, it is useful to represent a command as an \e action. An action can be added to a menu and a toolbar and will automatically keep them in sync. For example, if the user presses a Bold toolbar button the Bold menu item will automatically be checked. A TQAction may contain an icon, a menu text, an accelerator, a status text, a whats this text and a tool tip. Most of these can be set in the constructor. They can also be set independently with setIconSet(), setText(), setMenuText(), setToolTip(), setStatusTip(), setWhatsThis() and setAccel(). An action may be a toggle action e.g. a Bold toolbar button, or a command action, e.g. 'Open File' to invoke an open file dialog. Toggle actions emit the toggled() signal when their state changes. Both command and toggle actions emit the activated() signal when they are invoked. Use setToggleAction() to set an action's toggled status. To see if an action is a toggle action use isToggleAction(). A toggle action may be "on", isOn() returns TRUE, or "off", isOn() returns FALSE. Actions are added to widgets (menus or toolbars) using addTo(), and removed using removeFrom(). Once a TQAction has been created it should be added to the relevant menu and toolbar and then connected to the slot which will perform the action. For example: \quotefile action/application.cpp \skipto TQPixmap( fileopen \printuntil connect We create a "File Save" action with a menu text of "&Save" and \e{Ctrl+S} as the keyboard accelerator. We connect the fileSaveAction's activated() signal to our own save() slot. Note that at this point there is no menu or toolbar action, we'll add them next: \skipto new TQToolBar \printline \skipto fileSaveAction->addTo \printline \skipto new TQPopupMenu \printuntil insertItem \skipto fileSaveAction->addTo \printline We create a toolbar and add our fileSaveAction to it. Similarly we create a menu, add a top-level menu item, and add our fileSaveAction. We recommend that actions are created as children of the window that they are used in. In most cases actions will be children of the application's main window. To prevent recursion, don't create an action as a child of a widget that the action is later added to. */ class TQActionPrivate { public: TQActionPrivate(TQAction *act); ~TQActionPrivate(); TQIconSet *iconset; TQString text; TQString menutext; TQString tooltip; TQString statustip; TQString whatsthis; #ifndef QT_NO_ACCEL TQKeySequence key; TQAccel* accel; int accelid; #endif uint enabled : 1; uint visible : 1; uint toggleaction : 1; uint on : 1; uint forceDisabled : 1; uint forceInvisible : 1; #ifndef QT_NO_TOOLTIP TQToolTipGroup tipGroup; #endif TQActionGroupPrivate* d_group; TQAction *action; struct MenuItem { MenuItem():popup(0),id(0){} TQPopupMenu* popup; int id; }; // ComboItem is only necessary for actions that are // in dropdown/exclusive actiongroups.

For example, if you have a left justify action, a right justify action and a center action, only one of these actions should be active at any one time, and one simple way of achieving this is to group the actions together in an action group. An action group can also be added to a menu or a toolbar as a single unit, with all the actions within the action group appearing as separate menu options and toolbar buttons. Here's an example from examples/textedit: \quotefile textedit/textedit.cpp \skipto TQActionGroup \printuntil connect Here we create a new action group. Since the action group is exclusive by default, only one of the actions in the group is ever active at any one time. We then connect the group's selected() signal to our textAlign() slot. \printuntil actionAlignLeft->setToggleAction We create a left align action, add it to the toolbar and the menu and make it a toggle action. We create center and right align actions in exactly the same way. \omit A TQActionGroup emits an activated() signal when one of its actions is activated. \endomit The actions in an action group emit their activated() (and for toggle actions, toggled()) signals as usual. The setExclusive() function is used to ensure that only one action is active at any one time: it should be used with actions which have their \c toggleAction set to TRUE. Action group actions appear as individual menu options and toolbar buttons. For exclusive action groups use setUsesDropDown() to display the actions in a subwidget of any widget the action group is added to. For example, the actions would appear in a combobox in a toolbar or as a submenu in a menu. Actions can be added to an action group using add(), but normally they are added by creating the action with the action group as parent. Actions can have separators dividing them using addSeparator(). Action groups are added to widgets with addTo(). */ /*! Constructs an action group called \a name, with parent \a parent.
