Example
Creates a browser in which the volume can be controlled by pressing the page-up & page-down keys
--In order to render the browser on the full screen, we need to know the dimensions. local screenWidth, screenHeight = guiGetScreenSize() --Let's create a new browser in remote mode. local webBrowser = createBrowser(screenWidth, screenHeight, false, false) -- How much we increase/decrease the volume by each time local volumeStep = 0.1 -- The min/max value for the browser volume. Change these if you like, but note that the minimum value is 0 and the maximum value is 1. local MIN_VOLUME = 0 local MAX_VOLUME = 1 --Function to render the browser. function webBrowserRender() --Render the browser on the full size of the screen. dxDrawImage(0, 0, screenWidth, screenHeight, webBrowser, 0, 0, 0, tocolor(255,255,255,255), true) end --The event onClientBrowserCreated will be triggered, after the browser has been initialized. --After this event has been triggered, we will be able to load our URL and start drawing. addEventHandler("onClientBrowserCreated", webBrowser, function() --After the browser has been initialized, we can load www.youtube.com loadBrowserURL(webBrowser, "http://www.youtube.com") --Now we can start to render the browser. addEventHandler("onClientRender", root, webBrowserRender) end ) -- Now we create a function attached to an onClientKey event handler to catch user input. -- Here we can utilize the getBrowserVolume function to lower or increase the volume of the browser based on the clients input function handleVolumeKeys(button, press) if (press) then -- Is key pressed? if (button == "pgup") then local volume = getBrowserVolume(webBrowser) + volumeStep -- Get the current browser volume and add our volume step if (volume) > MAX_VOLUME then return end -- Check if the current volume is bigger than max value setBrowserVolume(webBrowser, volume) -- Set the browser volume elseif (button == "pgdn") then -- Same as previous condition except we subtract the volume step and make sure the volume value doesn't fall below minimum. local volume = getBrowserVolume(webBrowser) - volumeStep if (volume) < MIN_VOLUME then return end setBrowserVolume(webBrowser, volume) end end end addEventHandler("onClientKey", root, handleVolumeKeys)
