Moving ListBox scrollbar from code

[IgiLama]

Hi,

I want to implement functionality to ListBox that if something is draged into it and cursor is positioned near bottom/top, scrollbar will slowly scroll down/up so user can reach not currently visible components.

I haven't find any useful property or method of TListBox that can be used to change scrollbar position from code.

Anyone can help with this?

// scroll a list box vertically down by one line
SNDMSG(ListBox1->Handle, WM_VSCROLL, SB_LINEDOWN, 0); 
 

// Other scroll parameters that can be sent...
// SB_TOP          Scrolls to the upper left
// SB_BOTTOM       Scrolls to the lower right
// SB_ENDSCROLL    Ends scrolling
// SB_LINEDOWN     Scrolls one line down
// SB_LINEUP       Scrolls one line up 
// SB_PAGEDOWN     Scrolls one page down
// SB_PAGEUP       Scrolls one page up
