Returns

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 FALSE.

L_BOOL  AnnGetToolBarButtonVisibleExample(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 FALSE. */ 
   if (fVisible == TRUE) 
   { 
      *nRet = L_AnnSetToolBarChecked(hwndToolBar, uButton); 
      if(*nRet != SUCCESS) 
         return *nRet; 
      return(TRUE); 
   } 
   else 
   { 
      return(FALSE); 
   } 
}
