class TContextMenu: public TNamed


TContextMenu

This class provides an interface to  context sensitive popup menus.
These menus pop up when the user hits the right mouse button, and
are destroyed when the menu pops downs.

Context Menus are automatically generated by ROOT using the
following convention: if the string // *MENU* is found in the
comment field of a member function. This function will be added to
the list of items in the menu.

The picture below shows a canvas with a pop-up menu.

 Create a context menu.

~TContextMenu()

 Destroy a context menu.

 Action to be performed when this menu item is selected.
 If the selected method requires arguments we popup an
 automatically generated dialog, otherwise the method is
 directly executed.

void Action(TClassMenuItem* classmenuitem)

 Action to be performed when this menu item is selected.
 If the selected method requires arguments we popup an
 automatically generated dialog, otherwise the method is
 directly executed.

void Action(TObject* object, TToggle* toggle)

 Action to be performed when this toggle menu item is selected.

const char * CreateArgumentTitle(TMethodArg* argument)

 Create string describing argument (for use in dialog box).

const char * CreateDialogTitle(TObject* object, TFunction* method)

 Create title for dialog box retrieving argument values.

const char * CreatePopupTitle(TObject* object)

 Create title for popup menu.

void Execute(TObject* object, TFunction* method, const char* params)

 Execute method with specified arguments for specified object.

void Execute(TObject* object, TFunction* method, TObjArray* params)

 Execute method with specified arguments for specified object.

void Popup(Int_t x, Int_t y, TObject* obj, TVirtualPad* c = 0, TVirtualPad* p = 0)

 Popup context menu at given location in canvas c and pad p for selected
 object.

void Popup(Int_t x, Int_t y, TObject* obj, TBrowser* b)

 Popup context menu at given location in browser b for selected object.

TContextMenu(const TContextMenu& )

TContextMenu& operator=(const TContextMenu& )

void DisplayPopUp(Int_t x, Int_t y)

{ if (fContextMenuImp) fContextMenuImp->DisplayPopup(x, y); }

TContextMenu()
