Member Function Documentation

wxMenuItem * CONTEXT_MENU::Add ( const wxString &  aLabel, int  aId, const BITMAP_OPAQUE *  aIcon = NULL  )

inherited

Function Add() Adds an entry to the menu.

After highlighting/selecting the entry, a TOOL_EVENT command is sent that contains ID of the entry.

Parameters

aLabel	is the text label show in the menu.
aId	is the ID that is sent in the TOOL_EVENT. It should be unique for every entry.
aIcon	is an optional icon.

wxMenuItem * CONTEXT_MENU::Add ( const TOOL_ACTION &  aAction )

inherited

Function Add() Adds an entry to the menu, basing on the TOOL_ACTION object.

After selecting the entry, a TOOL_EVENT command containing name of the action is sent.

Parameters

aAction

is the action to be added to menu entry.

ID numbers for tool actions need to have a value higher than ACTION_ID

std::list< wxMenuItem * > CONTEXT_MENU::Add ( CONTEXT_MENU *  aMenu, bool  aExpand = false  )

inherited

Function Add() Adds a context menu as a submenu.

The difference between this function and wxMenu::AppendSubMenu() is the capability to handle icons.

Parameters

aMenu	is the submenu to be added.
aExpand	allows to add all entries from the menu as individual entries rather than add everything as a submenu.
