Detailed Description

ContextMenu: Similar to PushButton, but with several actions: Upon clicking on a ContextMenu (or activating it with the keyboard), a pop-up menu opens where the user can activate an action. Menu items in that pop-up menu can have submenus (that will pop up in separate pop-up menus).

Internally, this widget is more similar to the Tree widget. The difference is that it does not keep a "selected" status, but triggers an action right away, just like a PushButton. Like PushButton, ContextMenu sends an event right away when the user selects an item (clicks on a menu item or activates it with the keyboard). Items that have a submenu never send an event, they simply open their submenu when activated.

Note: unlike other widgets, this one is not created via YWidgetFactory or YOptionalWidgetFactory but with YApplication::openContextMenu()

Constructor & Destructor Documentation

◆ YContextMenu()

YContextMenu::YContextMenu ( )
protected

Constructor.

'label' is the user-visible text on the button (not above it like all other SelectionWidgets).

◆ ~YContextMenu()

YContextMenu::~YContextMenu ( )
virtual

Destructor.

Member Function Documentation

◆ addItem()

void YContextMenu::addItem ( YItem * item_disown)
virtual

Add one item. This widget assumes ownership of the item object and will delete it in its destructor.

This reimplementation will an index to the item that is unique for all items in this ContextMenu. That index can be used later with findMenuItem() to find the item by that index.

Reimplemented from YSelectionWidget.

Reimplemented from YSelectionWidget.

◆ addItems()

void YContextMenu::addItems ( const YItemCollection & itemCollection)
virtual

Add multiple items. For some UIs, this can be more efficient than calling addItem() multiple times. This function also automatically calls resolveShortcutConflicts() and rebuildMenuTree() at the end.

Derived classes can overwrite this function, but they should call this base class function at the end of the new implementation.

Reimplemented from YSelectionWidget.

Reimplemented from YSelectionWidget.

◆ deleteAllItems()

void YContextMenu::deleteAllItems ( )
virtual

Delete all items.

Reimplemented from YSelectionWidget.

Reimplemented from YSelectionWidget.

◆ findMenuItem() [1/2]

YMenuItem * YContextMenu::findMenuItem ( int index)
protected

Recursively find the first menu item with the specified index. Returns 0 if there is no such item.

◆ findMenuItem() [2/2]

YMenuItem * YContextMenu::findMenuItem ( int index,
YItemConstIterator begin,
YItemConstIterator end )
protected

Recursively find the first menu item with the specified index from iterator 'begin' to iterator 'end'.

Returns 0 if there is no such item.

◆ getProperty()

YPropertyValue YContextMenu::getProperty ( const std::string & propertyName)
virtual

Get a property. Reimplemented from YWidget.

This method may throw YUIPropertyExceptions.

Reimplemented from YWidget.

◆ itemAt()

YMenuItem * YContextMenu::itemAt ( int index)
inlineprotected

Alias for findMenuItem(). Reimplemented to ensure consistent behaviour with YSelectionWidget::itemAt().

◆ propertySet()

const YPropertySet & YContextMenu::propertySet ( )
virtual

Return this class's property set. This also initializes the property upon the first call.

Reimplemented from YWidget.

Reimplemented from YWidget.

◆ rebuildMenuTree()

virtual void YContextMenu::rebuildMenuTree ( )
pure virtual

Rebuild the displayed menu tree from the internally stored YMenuItems.

The application should call this (once) after all items have been added with addItem(). YContextMenu::addItems() calls this automatically.

Derived classes are required to implement this.

◆ resolveShortcutConflicts()

void YContextMenu::resolveShortcutConflicts ( )

Resolve keyboard shortcut conflicts: Change shortcuts of menu items if there are duplicates in the respective menu level.

This has to be called after all items are added, but before rebuildMenuTree() (see above). YContextMenu::addItems() calls this automatically.

◆ setProperty()

bool YContextMenu::setProperty ( const std::string & propertyName,
const YPropertyValue & val )
virtual

Set a property. Reimplemented from YWidget.

This function may throw YUIPropertyExceptions.

This function returns 'true' if the value was successfully set and 'false' if that value requires special handling (not in error cases: those are covered by exceptions).

Reimplemented from YWidget.

◆ widgetClass()

virtual const char * YContextMenu::widgetClass ( ) const
inlinevirtual

Returns a descriptive name of this widget class for logging, debugging etc.

Reimplemented from YSelectionWidget.
