Cancel button

[Xeno]

im making a login gui and im a bit stuck.... look

addEventHandler("onClientGUIClick",Cancel,CreateLoginWindow,false)

function CreateLoginWindow()

wdwLogin = guiCreateWindow(226,146,372,233,"[Admin Login System]",false)

guiWindowSetMovable(wdwLogin,false)

guiWindowSetSizable(wdwLogin,false)

tabpanel = guiCreateTabPanel(0.0242,0.0858,0.9489,0.8755,true,wdwLogin)

tab1 = guiCreateTab("Login",tabpanel)

login = guiCreateButton(0.1000,0.8611,0.2436,0.1167,"Login",true,tab1)

username = guiCreateLabel(0.0113,0.1167,0.3768,0.15,"UserName:",true,tab1)

guiLabelSetColor(username,255,255,255)

guiLabelSetVerticalAlign(username,"top")

guiLabelSetHorizontalAlign(username,"left",false)

guiSetFont(username,"default-bold-small")

password = guiCreateLabel(0.0113,0.2889,0.3768,0.15,"Password:",true,tab1)

guiLabelSetColor(password,255,255,255)

guiLabelSetVerticalAlign(password,"top")

guiLabelSetHorizontalAlign(password,"left",false)

guiSetFont(password,"default-bold-small")

username = guiCreateEdit(0.2266,0.1,0.3598,0.1389,localPlayerName,true,tab1)

password = guiCreateEdit(0.2266,0.2611,0.3598,0.1389,"",true,tab1)

Canel = guiCreateButton( 0.4, 0.85, 0.20, 0.15, "Cancel", true,tab1 )

guiEditSetMasked(password,true)

tab2 = guiCreateTab("Info",tabpanel)

wow, a messy code.. try to get basics of Lua, its probably your 1st script and its too hard, i think you dont know any progamming logic

function HideWindow()
guiSetVisible(wdwLogin,false)
showCursor (false)  -- you forgeet about this
end
 
function createWindow ( res ) -- this function creates a login window and show the cursor
wdwLogin = guiCreateWindow(226,146,372,233,"[Admin Login System]",false)
guiWindowSetMovable(wdwLogin,false)
guiWindowSetSizable(wdwLogin,false)
tabpanel = guiCreateTabPanel(0.0242,0.0858,0.9489,0.8755,true,wdwLogin)
tab1 = guiCreateTab("Login",tabpanel)
login = guiCreateButton(0.1000,0.8611,0.2436,0.1167,"Login",true,tab1)
username = guiCreateLabel(0.0113,0.1167,0.3768,0.15,"UserName:",true,tab1)
guiLabelSetColor(username,255,255,255)
guiLabelSetVerticalAlign(username,"top")
guiLabelSetHorizontalAlign(username,"left",false)
guiSetFont(username,"default-bold-small")
password = guiCreateLabel(0.0113,0.2889,0.3768,0.15,"Password:",true,tab1)
guiLabelSetColor(password,255,255,255)
guiLabelSetVerticalAlign(password,"top")
guiLabelSetHorizontalAlign(password,"left",false)
guiSetFont(password,"default-bold-small")
username = guiCreateEdit(0.2266,0.1,0.3598,0.1389,localPlayerName,true,tab1)
password = guiCreateEdit(0.2266,0.2611,0.3598,0.1389,"",true,tab1)
Canel = guiCreateButton( 0.4, 0.85, 0.20, 0.15, "Cancel", true,tab1 )
guiEditSetMasked(password,true)
tab2 = guiCreateTab("Info",tabpanel)
showCursor (true)  -- you forgot about this
addEventHandler("onClientGUIClick",Cancel,HideWindow,false) -- "HideWindow" will be fired when somebody hits cancel
end
 
addEventHandler ( "onResourceStart", getRootElement(), createWindow ) -- "createWindow" will be fired when resource starts/player join

that is better, right?

download MTA Script Editor, it will help you a lot, really

and dont forget about

https://wiki.multitheftauto.com/wiki/Main_Page

(on the menu on the left, there are useful lists of Events/Functions)

good luck

ps. SCRIPT ABOVE NOT TESTED, if you messed something more than i think, try to fix it by yourself

Thats more clearly:

function CreateLoginWindow()
 
   wdwLogin = guiCreateWindow( 226, 146, 372, 233, "[Admin Login System]", false )
guiSetVisible( wdwLogin, false )
guiWindowSetMovable( wdwLogin, false )
guiWindowSetSizable( wdwLogin, false )
 
   tabpanel = guiCreateTabPanel( 0.0242, 0.0858, 0.9489, 0.8755, true, wdwLogin )
 
   tab1 = guiCreateTab( "Login", tabpanel )
       login = guiCreateButton( 0.1000, 0.8611, 0.2436, 0.1167, "Login", true, tab1 )
       username = guiCreateLabel( 0.0113, 0.1167, 0.3768, 0.15, "UserName:", true,tab1 )
guiSetFont(username,"default-bold-small")
       password = guiCreateLabel( 0.0113, 0.2889, 0.3768, 0.15, "Password:", true, tab1 )
guiSetFont( password, "default-bold-small" )
       username = guiCreateEdit( 0.2266, 0.1, 0.3598, 0.1389, localPlayerName, true, tab1 )
       password = guiCreateEdit( 0.2266, 0.2611, 0.3598, 0.1389,"", true, tab1 )
       Cancel = guiCreateButton( 0.4, 0.85, 0.20, 0.15, "Cancel", true, tab1 ) -- you wrote "Canel"
guiEditSetMasked( password, true )
 
   tab2 = guiCreateTab( "Info", tabpanel )
 
addEventHandler( "onClientGUIClick", Cancel, CloseLoginWindow, false ) -- You must add the EventHandler in function, because before the button-element is nil
-- call a new function for closing Window, but first you need a function to show the window, because of "guiSetVisible( wdwLogin, false )" in the top of this function
 
end
 
function openLoginWindow() -- call it when it should open, maybe with the Event "onClientResourceStart"
 
guiSetVisible( wdwLogin, true )
showCursor( true ) -- You need this for clicking the Button
 
end
 
function closeLoginWindow()
 
guiSetVisible( wdwLogin, false )
showCursor( false )
 
end

You don't need to do this functions:

guiLabelSetColor(username,255,255,255)

guiLabelSetVerticalAlign(username,"top")

guiLabelSetHorizontalAlign(username,"left",false)

Because that Arguments are the defaults of Labels I mean.

I'll just point this out too that was not mentioned in the code comments, as everyone makes this mistake.

addEventHandler( "onClientGUIClick", Cancel, CloseLoginWindow, false )

Note the last argument is false. If you are familiar with the wiki description, you know that it is the "getPropagated" argument.

If it was set to true, it would receive the click event from any parent or child of the button in the element tree. If you don't understand the element tree, it's worth learning, but I won't go into it now.

What it results in is if the window is open, naturally your button is a "child" of the window. So with it set true, if you click anywhere within the window, the button will receive the event as if you clicked on the button itself. The mouse click event "propagated" down the element tree. And the problem is then multiplied with several GUIClick event handlers, if say, you had several buttons on this form and an event for each.

getPropagated = false means the event has to directly involve this element - in this case, you have to click this button (your "Cancel" button element in the case of this code snippet) for the event to work. Note you use propagated all the time normally, so don't set it false all the time - for example any event attached to the root element is likely to use it, as a large majority of events don't trigger on the root element itself. (You may want to catch when any player is spawning for example, but that triggers on the player element involved.)

Just remember to set it false when dealing with GUI.
