L_BOOL *pfVisible

Address of the variable to be updated with a value indicating whether the specified tool is visible. Possible values are:

Value	Meaning
TRUE	The tool is visible.
FALSE	The tool is not visible.

Returns

Value	Meaning
SUCCESS	The function was successful.
< 1	An error occurred. Refer to Return Codes.

Comments

When a tool is invisible, other tools in the toolbar are arranged so that no gaps are left, and so that their order is maintained (left-to-right and top-to-bottom, just as text would wrap).

Before calling this function, you must declare a variable of data type L_BOOL. Then, pass the address of the variable in the pfVisible parameter. This function will update the variable with TRUE or FALSE.

Example

This example sets the specified button as the current button if it is visible. Otherwise, it returns L_FALSE.

L_BOOL AnnGetToolBarButtonVisibleExample(L_HWND hwndToolBar, L_UINT uButton, L_INT * nRet) 
{ 
   L_BOOL   fVisible; 
 
   /* See if the specified button is visible */ 
   *nRet = L_AnnGetToolBarButtonVisible(hwndToolBar, uButton, &fVisible); 
   if (*nRet != SUCCESS) 
      return *nRet; 
 
   /* If it is visible, set it. Otherwise, return L_FALSE. */ 
   if (fVisible == L_TRUE) 
   { 
      *nRet = L_AnnSetToolBarChecked(hwndToolBar, uButton); 
      if (*nRet != SUCCESS) 
         return *nRet; 
 
      return(L_TRUE); 
   } 
   else 
   { 
      return(L_FALSE); 
   } 
}
