## Detailed Description

A ribbon button bar is similar to a traditional toolbar.

It contains one or more buttons (button bar buttons, not wxButtons), each of which has a label and an icon. It differs from a wxRibbonToolBar in several ways:

- Individual buttons can grow and contract.
- Buttons have labels as well as bitmaps.
- Bitmaps are typically larger (at least 32x32 pixels) on a button bar compared to a tool bar (which typically has 16x15).
- There is no grouping of buttons on a button bar
- A button bar typically has a border around each individual button, whereas a tool bar typically has a border around each group of buttons.

## Events emitted by this class

The following event handler macros redirect the events to member function handlers 'func' with prototypes like:

void handlerFuncName(wxRibbonButtonBarEvent& event)

Event macros for events emitted by this class:

- EVT_RIBBONBUTTONBAR_CLICKED(id, func):
  Triggered when the normal (non-dropdown) region of a button on the button bar is clicked.
- EVT_RIBBONBUTTONBAR_DROPDOWN_CLICKED(id, func):
  Triggered when the dropdown region of a button on the button bar is clicked. wxRibbonButtonBarEvent::PopupMenu() should be called by the event handler if it wants to display a popup menu (which is what most dropdown buttons should be doing).

## Constructor & Destructor Documentation

wxRibbonButtonBar::wxRibbonButtonBar | ( |  | ) |

Default constructor.

With this constructor, Create() should be called in order to create the button bar.

wxRibbonButtonBar::wxRibbonButtonBar | ( | wxWindow * | parent,
|  | wxWindowID | id = `wxID_ANY`,
|  | const wxPoint & | pos = `wxDefaultPosition`,
|  | const wxSize & | size = `wxDefaultSize`,
|  | long | style = `0` |
| ) |  |  |

Construct a ribbon button bar with the given parameters.

Parameters:

  | parent | Parent window for the button bar (typically a wxRibbonPanel).
  | id | An identifier for the button bar. `wxID_ANY` is taken to mean a default.
  | pos | Initial position of the button bar.
  | size | Initial size of the button bar.
  | style | Button bar style, currently unused.

virtual wxRibbonButtonBar::~wxRibbonButtonBar | ( |  | ) | `[virtual]`

Destructor.

## Member Function Documentation

virtual wxRibbonButtonBarButtonBase* wxRibbonButtonBar::AddButton | ( | int | button_id,
|  | const wxString & | label,
|  | const wxBitmap & | bitmap,
|  | const wxString & | help_string,
|  | wxRibbonButtonBarButtonKind | kind = `wxRIBBON_BUTTONBAR_BUTTON_NORMAL` |
| ) |  |  | `[virtual]`

Add a button to the button bar (simple version).

virtual wxRibbonButtonBarButtonBase* wxRibbonButtonBar::AddButton | ( | int | button_id,
|  | const wxString & | label,
|  | const wxBitmap & | bitmap,
|  | const wxBitmap & | bitmap_small = `wxNullBitmap`,
|  | const wxBitmap & | bitmap_disabled = `wxNullBitmap`,
|  | const wxBitmap & | bitmap_small_disabled = `wxNullBitmap`,
|  | wxRibbonButtonBarButtonKind | kind = `wxRIBBON_BUTTONBAR_BUTTON_NORMAL`,
|  | const wxString & | help_string = `wxEmptyString`,
|  | wxObject * | client_data = `NULL` |
| ) |  |  | `[virtual]`

Add a button to the button bar.

Parameters:

  | button_id | ID of the new button (used for event callbacks).
  | label | Label of the new button.
  | bitmap | Large bitmap of the new button. Must be the same size as all other large bitmaps used on the button bar.
  | bitmap_small | Small bitmap of the new button. If left as null, then a small bitmap will be automatically generated. Must be the same size as all other small bitmaps used on the button bar.
  | bitmap_disabled | Large bitmap of the new button when it is disabled. If left as null, then a bitmap will be automatically generated from bitmap.
  | bitmap_small_disabled | Small bitmap of the new button when it is disabled. If left as null, then a bitmap will be automatically generated from bitmap_small.
  | kind | The kind of button to add.
  | help_string | The UI help string to associate with the new button.
  | client_data | Client data to associate with the new button.

Returns:
  An opaque pointer which can be used only with other button bar methods.

| ) |  |  |

Create a button bar in two-step button bar construction.

Should only be called when the default constructor is used, and arguments have the same meaning as in the full constructor.

virtual bool wxRibbonButtonBar::DeleteButton | ( | int | button_id | ) | `[virtual]`

Delete a single button from the button bar.

  ClearButtons()

virtual void wxRibbonButtonBar::EnableButton | ( | int | button_id,
