itemIdxItem index.
bInCurrPageThe parameter can be only used for displayer of Browser type:
  • @TRUE - the parameter itemIdx defines the item index on the currently displayed page of the Browser  
  • @FALSE - the parameter itemIdx defines the item index regardless of the paging (within the frame of the entire Browser)
bStateThe parameter can be only used for displayer of Browser type:
  • @TRUE - the line is to be selected
  • @FALSE - the line is to be deselected
iFromIdxThe 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.

Example: If the selection comprises lines 1, 3 and 5 and the iFromIdx parameter is set to the value of 3, the function returns 5.
NoteIf 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.
