TB_GETBUTTONINFO message
Retrieves extended information for a button in a toolbar.
Parameters
-
wParam
-
Command identifier of the button.
-
lParam
-
Pointer to a TBBUTTONINFO structure that receives the button information. The cbSize and dwMask members of this structure must be filled in prior to sending this message.
Return value
Returns the zero-based index of the button, or -1 if an error occurs.
Remarks
When you use TB_ADDBUTTONS or TB_INSERTBUTTON to place buttons on the toolbar, the button text is commonly specified by its string pool index. TB_GETBUTTONINFO will not retrieve this string. To use TB_GETBUTTONINFO to retrieve button text, you must first set the text string with TB_SETBUTTONINFO. Once you have set the button text with TB_SETBUTTONINFO, you can no longer use the string pool index.
