UIHANDLER OnCursorChanged

Called whenever the cursor in an edit box was moved. Note that the cursor is also moved when typing.

• arg1 : the new horizontal (x) position of the cursor in the edit box (the first column being 0, increasing to the right)
• arg2 : the new vertical (y) position of the cursor in the edit box (the first line being 0, DEcreasing downwards)
• arg3 : the width of the displayed cursor
• arg4 : the height of one line/the displayed cursor

Say we have a plain textbox inside a scrollframe (inside UIPanelScrollFrameTemplate; as the only child-element, etc.), the following code will automatically move scrollframe viewport so that the cursor is inside it. (The ScrollingEdit_OnUpdate function in UIPanelTemplates.lua does something akin to this also.) <OnCursorChanged> local vs = self:GetParent:GetVerticalScroll; local h = self:GetParent:GetHeight; if vs+arg2 > 0 or 0 > vs+arg2-arg4+h then self:GetParent:SetVerticalScroll(arg2*-1); end </OnCursorChanged>
