API:SetItemDragging

UI Lua API · Interface functions
Version: WAR 1.4.8

Tells the client that something is being dragged on the cursor. While set, windows do not fire their game actions.

SetItemDragging(dragging)

Arguments

dragging: boolean – true while an icon is held on the cursor, false when it is released.

Nothing.

While the flag is true, a window that has a game action does not run it when it is clicked, and WindowGameAction does nothing. The window's normal Lua handlers (OnLButtonUp and so on) still run.
The flag is off when the client starts and stays as set until changed again. Remember to clear it.
dragging must be a real boolean. Passing nil or a number raises an Invalid Parameters error.

None besides the Invalid Parameters argument check.

From ea_cursor/source/cursor.lua, when an icon is picked up:

local texture, x, y = GetIconData( Cursor.Data.IconId )
SetCursor( texture )

SetItemDragging(true)

and at the end of Cursor.Clear:

SetItemDragging(false)
