Enumeration 100

#WebView
EndEnumeration
OpenWindow(#Window, 100, 100, 400, 200, "Test", #PB_Window_MinimizeGadget | #PB_Window_ScreenCentered)
WebViewGadget(#WebView, 0, 0, 400, 200)
SetGadgetItemText(#WebView, #PB_WebView_HtmlCode, ~"<script>ctx = new AudioContext(); osc = ctx.createOscillator(); osc.type = 'sine'; osc.frequency.value = 1; osc.connect(ctx.destination);</script>")
WebViewExecuteScript(#WebView, ~"osc.start();")
Repeat

Until Event = #PB_Event_CloseWindow
