Detailed Description

template<class State_t>
class GlsMenuItem_T< State_t >

This provides the functionality of a menu item. A menu item can contain one or more states that are visible at different instances. The current state is the first one found that is currently visible.

The class is templatized so that users can provide their own extended menu item state class as the states of the menu item. The State_t template parameter must be a class derived from GlsMenuItemState.

GlsMenuItem_T< State_t >::GlsMenuItem_T	(	const std::string &	name,
		GlsMenuDictionary &	dataDict,
		GlsMenuAction::HandlerCont_t &	actionHandlers
	)

inline

Class constructor.

Parameters

name	name of menu item. This usually refers to a location of an item, as the states of the item can contain different labels.
dataDict	the meta-data dictionary used for looking up the values of variables. This is passed on to the item's states when they are created for them to use.
actionHandlers	These are handlers for menu actions passed in by the creator. These are considered local to the menu set.

Member Function Documentation

const GlsMenuDictionary& GlsMenuDataGroup::Attributes ( ) const

inlineinherited

Read attribute dictionary from an input stream.

Parameters

instr input stream to read value from.

Definition at line 78 of file gls_menu_data_group.h.

References GlsMenuDataGroup::_attr.

Referenced by GlsMFDMenu_T< MenuItem_t, Submenu_t, PageId_t >::ReadValue().

virtual GlsMenuData* GlsMenuHandlerGroup_T< State_t >::CreateDataItem ( const std::string & name ) const

inlineprotectedvirtualinherited

Create a new instance of our particular data item type. In this case, it is an menu item that will accept action handlers, since it or one of its components will handle actions.

Parameters

name	name of the data item.

Returns: a pointer to the item or 0 if the item cannot be created.

Implements GlsMenuDynDataGroup.

Definition at line 319 of file gls_menu_data_group.h.

virtual void GlsMenuData::Inc ( long amount = 1 )

virtualinherited

Increment the data item. Derived classes must override this as the default is a no-op.

Reimplemented in GlsMenuDiscrete_T< T >.

Referenced by GlsMenuSet_T< MenuType_t, DataFactory_t >::IncData().

State_t * GlsMenuHandlerGroup_T< State_t >::Item ( const std::string & name ) const

inlineinherited

Gain access to a particular meta-data item within the group.

Parameters

name	name of the meta-data item.

Returns: a pointer to the item or 0 if the item does not exist within the group.

Definition at line 294 of file gls_menu_data_group.h.

virtual std::istream& GlsMenuDynDataGroup::ReadValue ( std::istream & instr )

virtualinherited

Read attribute dictionary from an input stream.

Parameters

instr input stream to read value from.

Reimplemented from GlsMenuDataGroup.

template<class State_t >

void GlsMenuItem_T< State_t >::Select ( )

inline

The menu item has been selected, so notify the current state, if any, that it has been selected. This should activate all callbacks.

Definition at line 263 of file gls_menu_item.h.

References GlsMenuItem_T< State_t >::_currentState.

template<class State_t >

State_t* GlsMenuItem_T< State_t >::State ( )

inline

Returns the current state of the menu item and checks the timers of all its menu item states. This should be called on a cyclical basis if the timer mechanism is to work properly. This should be used to update the state of the menu item on some display. The state should determine how the item looks on the display.

Definition at line 233 of file gls_menu_item.h.

References GlsMenuDataGroup::_attr, and GlsMenuItem_T< State_t >::_currentState.

virtual std::ostream& GlsMenuDataGroup::WriteValue ( std::ostream & outstr )

virtualinherited

Read attribute dictionary from an input stream.

Parameters

instr input stream to read value from.
