This function sets the current position of the caret (the text cursor) within the edit box.

Syntax

bool guiEditSetCaretIndex ( element theElement, int index )

OOP Syntax Help! I don't understand this!

Method: GuiEdit:setCaretIndex(...)
Variable: .caretIndex
Counterpart: guiEditGetCaretIndex


Required Arguments

  • theElement: The edit box to be changed.
  • index: An integer referring to the desired position within the box.

Returns

Returns true if the index was successfully set, false otherwise.

Example

This example makes the text cursor jump to the end of an edit box if the user is holding the Left Control button. 

function moveToEndOnClick()
	if ( getKeyState ( "lctrl" ) == true ) and ( getElementType(source) == "gui-edit" ) then          -- if the user is holding down left control
		local text = guiGetText ( source )
		local textLength = string.len ( text )
		guiEditSetCaretIndex ( source, textLength )  -- set the caret index. No need to check if the clicked control is actually an edit box as this function won't work on other controls anyway
	end
end
addEventHandler ( "onClientGUIClick", getRootElement(), moveToEndOnClick )    -- add an event handler for clicks
