The parameter can be only used for displayer of Browser type:

of the Browser
-

the frame of the entire Browser)

| bState |
The parameter can be only used for displayer of Browser type:
- @TRUE - the line is to be selected
- @FALSE - the line is to be deselected
|
| iFromIdx |
The parameter can only be used if the browser is in multiselect mode - it sets the
index, from which the selected line will be looked for.

set to the value of 3, the function returns 5.

If no item is selected, the function %HI_GetSelectedItem returns the value of 0.
For displayer of Tree view type, the parameter itemIdx is the
unique identifier of the item.
If the function %HI_SetSelectedItem is called on some item in Tree which
is out of displayed area, the scrollbars will adjust automatically to
see the selected item.
