Заметки
The lpButtons pointer points to an array of TBBUTTON structures. Each TBBUTTON structure associates the button being added with the button's style, image and/or string, command ID, state, and user-defined data:
typedef struct _TBBUTTON {
int iBitmap;// zero-based index of button image
int idCommand; // command to be sent when button pressed
BYTE fsState; // button state--see below
BYTE fsStyle; // button style--see below
DWORD dwData; // application-defined value
int iString;// zero-based index of button label string
} TBBUTTON;
The members are as follows:
iBitmap
Zero-based index of button image, -1 if no image for this button.idCommand
Command identifier associated with the button. This identifier is sent in a WM_COMMAND message when the button is chosen. If the fsStyle member has the TBSTYLE_SEP value, this member must be zero.fsState
Button state flags. It can be a combination of the values listed below:TBSTATE_CHECKED The button has the TBSTYLE_CHECKED style and is being pressed.
TBSTATE_ENABLED The button accepts user input. A button that does not have this state does not accept user input and is grayed.
TBSTATE_HIDDEN The button is not visible and cannot receive user input.
TBSTATE_INDETERMINATE The button is grayed.
TBSTATE_PRESSED The button is being pressed.
TBSTATE_WRAP A line break follows the button. The button must also have the TBSTATE_ENABLED state.
fsStyle
Button style. It can be a combination of the values listed below:TBSTYLE_BUTTON Creates a standard push button.
TBSTYLE_CHECK Creates a button that toggles between the pressed and unpressed states each time the user clicks it. The button has a different background color when it is in the pressed state.
TBSTYLE_CHECKGROUP Creates a check button that stays pressed until another button in the group is pressed.
TBSTYLE_GROUP Creates a button that stays pressed until another button in the group is pressed.
TBSTYLE_SEP Creates a separator, providing a small gap between button groups. A button that has this style does not receive user input.
dwData
User-defined data.iString
Zero-based index of the string to use as the button's label, -1 if there is no string for this button.
The image and/or string whose index you provide must have previously been added to the toolbar control's list using AddBitmap, AddString, and/or AddStrings.
