Reason(s): middle button does not trigger this event.--50pence 12:19, 19 May 2008 (CDT)

This event is fired when the user clicks a GUI element.


string button, string state, int absoluteX, int absoluteY
  • button: the name of the mouse button that the GUI element was clicked with, can be left, right, or middle.
  • state: the state of the mouse button, will be down if the mouse button was pushed, or up if it was released.
  • absoluteX: the X position of the mouse cursor, in pixels, measured from the left side of the screen.
  • absoluteY: the Y position of the mouse cursor, in pixels, measured from the top of the screen.


The source of this event is the GUI element that was clicked.


This example creates an edit box alongside an "Output!" button. When the button is clicked with the left mouse button, it will output the message in the edit box into the Chat Box.

--create our button
btnOutput = guiCreateButton( 0.7, 0.1, 0.2, 0.1, "Output!", true )

--Create an edit box and define it as "editBox".
editBox = guiCreateEdit( 0.3, 0.1, 0.4, 0.1, "Type your message here!", true )
guiEditSetMaxLength ( editBox, 128 ) --the max chatbox length is 128, so force this

--setup our function to output the message to the chatbox
function outputEditBox (button)
    if button == "left" then
        local text = guiGetText ( editBox )--get the text from the edit box
        outputChatBox ( text ) --output that text
--and attach our button to the outputEditBox function
addEventHandler ( "onClientGUIClick", btnOutput, outputEditBox, false )
