window = guiCreateWindow(126, 122, 848, 674, "Firechrome", false)
guiWindowSetSizable(window, false)

navigateBackBtn = guiCreateButton(10, 19, 39, 36, "<", false, window)
navigateForwardBtn = guiCreateButton(98, 19, 39, 36, ">", false, window)
addressBar =  guiCreateEdit(137, 19, 701, 36, "", false, window)
guiSetEnabled( addressBar, false )
reloadBtn = guiCreateButton(49, 19, 49, 36, "reload", false, window)
browser = guiCreateBrowser(10, 55, 828, 609, false, false, false, window)

-- Load our page on browser creation.
local theBrowser = guiGetBrowser(browser) 
addEventHandler("onClientBrowserCreated", theBrowser, 
    function()
        loadBrowserURL(source, "https://forum.mtasa.com/")
    end
)

-- This checks to see if the browser can navigate in any direction and enables the back or forward buttons
addEventHandler( "onClientBrowserDocumentReady", theBrowser, function( )
    navigateForwardBtn.enabled = (canBrowserNavigateForward(theBrowser))
    navigateBackBtn.enabled = (canBrowserNavigateBack(theBrowser))
    guiSetText( addressBar, getBrowserURL( theBrowser ) )
end )

-- This part handles the GUI navigation buttons for the browser.
addEventHandler( "onClientGUIClick", resourceRoot, function ( )
    if source == navigateBackBtn then
        navigateBrowserBack(theBrowser)
    elseif source == navigateForwardBtn then
        navigateBrowserForward(theBrowser)
