Button Messages | This topic discusses messages that are used with buttons. |
Button States | This section discusses how selecting a button changes its state and how the application should respond. |
Button Types | This topic discusses the different kinds of buttons. |
Using Buttons | This section explains how to perform certains tasks associated with buttons. |

Topic | Contents |
---|---|
BCN_DROPDOWN | Sent when the user clicks a drop down arrow on a button. The parent window of the control receives this notification code in the form of a WM_NOTIFY message. |
BCN_HOTITEMCHANGE | Notifies the button control owner that the mouse is entering or leaving the client area of the button control. The button control sends this notification code in the form of a WM_NOTIFY message. |
BN_CLICKED | Sent when the user clicks a button. The parent window of the button receives the BN_CLICKED notification code through the WM_COMMAND message. |
BN_DBLCLK | Sent when the user double-clicks a button. This notification code is sent automatically for BS_USERBUTTON, BS_RADIOBUTTON, and BS_OWNERDRAW buttons. Other button types send BN_DBLCLK only if they have the BS_NOTIFY style. The parent window of the button receives the BN_DBLCLK notification code through the WM_COMMAND message. |
BN_DISABLE | Sent when a button is disabled. Note: This notification code is provided only for compatibility with 16-bit versions of Windows earlier than version 3.0. Applications should use the BS_OWNERDRAW button style and the DRAWITEMSTRUCT structure for this task. The parent window of the button receives the BN_DISABLE notification code through the WM_COMMAND message. |
BN_DOUBLECLICKED | Sent when the user double-clicks a button. This notification code is sent automatically for BS_USERBUTTON, BS_RADIOBUTTON, and BS_OWNERDRAW buttons. Other button types send BN_DOUBLECLICKED only if they have the BS_NOTIFY style. The parent window of the button receives the BN_DOUBLECLICKED notification code through the WM_COMMAND message. |
BN_HILITE | Sent when the user selects a button. Note: This notification code is provided only for compatibility with 16-bit versions of Windows earlier than version 3.0. Applications should use the BS_OWNERDRAW button style and the DRAWITEMSTRUCT structure for this task. The parent window of the button receives the BN_HILITE notification code through the WM_COMMAND message. |
BN_KILLFOCUS | Sent when a button loses the keyboard focus. The button must have the BS_NOTIFY style to send this notification code. The parent window of the button receives the BN_KILLFOCUS notification code through the WM_COMMAND message. |
BN_PAINT | Sent when a button should be painted. Note: This notification code is provided only for compatibility with 16-bit versions of Windows earlier than version 3.0. Applications should use the BS_OWNERDRAW button style and the DRAWITEMSTRUCT structure for this task. The parent window of the button receives the BN_PAINT notification code through the WM_COMMAND message. |
BN_PUSHED | Sent when the push state of a button is set to pushed. Note: This notification code is provided only for compatibility with 16-bit versions of Windows earlier than version 3.0. Applications should use the BS_OWNERDRAW button style and the DRAWITEMSTRUCT structure for this task. The parent window of the button receives the BN_PUSHED notification code through the WM_COMMAND message. |
BN_SETFOCUS | Sent when a button receives the keyboard focus. The button must have the BS_NOTIFY style to send this notification code. The parent window of the button receives the BN_SETFOCUS notification code through the WM_COMMAND message. |
BN_UNHILITE | Sent when the highlight should be removed from a button. Note: This notification code is provided only for compatibility with 16-bit versions of Windows earlier than version 3.0. Applications should use the BS_OWNERDRAW button style and the DRAWITEMSTRUCT structure for this task. The parent window of the button receives the BN_UNHILITE notification code through the WM_COMMAND message. |
BN_UNPUSHED | Sent when the push state of a button is set to unpushed. Note: This notification code is provided only for compatibility with 16-bit versions of Windows earlier than version 3.0. Applications should use the BS_OWNERDRAW button style and the DRAWITEMSTRUCT structure for this task. The parent window of the button receives the BN_UNPUSHED notification code through the WM_COMMAND message. |
NM_CUSTOMDRAW (button) | Notifies the parent window of a button control about custom draw operations on the button. The button control sends this notification code in the form of a WM_NOTIFY message. |
WM_CTLCOLORBTN | The WM_CTLCOLORBTN message is sent to the parent window of a button before drawing the button. The parent window can change the button's text and background colors. However, only owner-drawn buttons respond to the parent window processing this message. |
Topic | Contents |

BUTTON_IMAGELIST | Contains information about an image list that is used with a button control. |
