* wasm: Add OpenGL version checkMorten Johan Sørvig2020-03-241-4/+15
| | | | | | | | | | | | | QtQuick3D probes for the supported OpenGL level by testing multiple OpenGL versions in descending order. Context creation must fail for versions not supported by WebGL. It does not appear that Emscripten does this for the 3.x minor versions, at least. Add version check which allows OpenGL (ES) 3.0 and 2.0.

* wasm: Specify event targets by CSS selectors; Support emsdk >= 1.39.5Morten Johan Sørvig2020-02-051-1/+2
| | | | | | | | | | | | | | | | DISABLE_DEPRECATED_FIND_EVENT_TARGET_BEHAVIOR is now on by default, which means that functions like emscripten_set_keydown_callback() now expects CSS selectors (e.g. "#canvas_id" instead of "canvas_id"). In addition, Module.canvas is no more. Add a deprecation warning in case someone is setting it and expects Qt to use it. (qtloader.js sets qtCanvasElements instead). This bumps the minimum supported emsdk version to 1.39.5. Fixes: QTBUG-74601 Change-Id: I8c46ce170143f969e6281824f78b1bb809c267ab Reviewed-by: Lorn Potter <lorn.potter@gmail.com>
* wasm: do not get canvas as property of js global objectAlexandra Cherdantseva2020-01-131-1/+1
| | | | | | | | | You cannot be sure that property with specified key in a global object is really a canvas. Should use `document.getElementById`. Change-Id: Ife55adaad5517aed64122b0c9bff32489cf19a2f Reviewed-by: Lorn Potter <lorn.potter@gmail.com>
* Prevent emscripten_webgl_destroy_context from removing event handlersMorten Johan Sørvig2019-12-031-0/+7
| | | | | | | | | | | | | | | | | | | | The JavaScript implementation of that function has the following code: if (typeof JSEvents === 'object') JSEvents.removeAllHandlersOnTarget(GL.contexts[contextHandle].GLctx.canvas); // Release all // JS event handlers on the DOM element that the GL context is associated with since the context // is now deleted. This breaks mouse/keyboard events, etc. Disable this logic by temporarily setting the JSEvents object to undefined, for the duration of the emscripten_webgl_destroy_context call.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We don’t need the contextLost callback since we can poll for the “lost” status in isValid() Recreating the native context is not very helpful, since it destroys all current context state. Remove this logic. Support makeCurrent() on different surfaces, as long as they refer to the same screen.

* wasm: support rendering to multiple canvasesMorten Johan Sørvig2019-03-081-3/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Qt (via the the qtloader.js API) now supports rendering to multiple canvases. The application sees each canvas as a QScreen. Make qtloader.js support multiple canvases: var qtloader = QtLoader({ canvasElements : [array-of-canvas], showCanvas: function() { // make canvas(es) visible }, }); The canvases were previously created/returned by showCanvas(), however this function is called after the Qt app has been started and adding screens that that point is too late. (This worked before since there was only one screen, and no need to connect each screen instance to specific canvas.) Remove QWasmScreen, QWasmCompositor, and QWasmEventTranslator singletons from QWasmIntegration. These are are now crated per-screen and are owned by the QWasmScreen.
