## Detailed Description

Menu builder interface.

Application delegates can implement this interface to customize the visibility and order of commands shown in the menu of the application or window. On platforms where the menu is sitting in the window, the window controllers menu builder is used if it has one. The context parameter of the methods is either an IApplication or IWindow.

## Member Typedef Documentation

using SortFunction = std::function<bool (const UTF8String& lhs, const UTF8String& rhs)>

## Member Function Documentation

virtual SortFunction getCommandGroupSortFunction | ( | const Interface & | context,
|  | const UTF8String & | group
| ) |  | const
| pure virtual

return command group sort function

Parameters

  context | either an IApplication or IWindow instance
  group | group name

Returns
  if you want to sort the menu return a SortFunction otherwise return nullptr

Implemented in MenuBuilderAdapter.

virtual bool prependMenuSeparator | ( | const Interface & | context,
|  | const Command & | cmd
| ) |  | const
| pure virtual

should a menu separator prepend a command

Parameters

  context | either an IApplication or IWindow instance
  cmd | command

Returns
  true if a menu separator should be prepended before the command

Implemented in MenuBuilderAdapter.

virtual bool showCommandGroupInMenu | ( | const Interface & | context,
|  | const UTF8String & | group
| ) |  | const
| pure virtual

should the command group be visible in the menu

Parameters

  context | either an IApplication or IWindow instance
  group | group name

Returns
  true for visible or false for invisible

Implemented in NoMenuBuilder, and MenuBuilderAdapter.

virtual bool showCommandInMenu | ( | const Interface & | context,
|  | const Command & | cmd
| ) |  | const
| pure virtual

should the command be visible in the menu

Parameters

  context | either an IApplication or IWindow instance
  cmd | command

Returns
  true for visible or false for invisible

Implemented in NoMenuBuilder, and MenuBuilderAdapter.
