* QWasmEventTranslator: replace five QHash with constexpr C arraysMarc Mutz2019-07-161-36/+0
| | | | | | | | | | | | | The mapping is static, but a dynamic (even mutable) container was used. Fix by using C tables and liner scan, which will be just as fast or faster than a hash lookup, for the maximum of six entries of each table.

* wasm: install one browser window resize handlerMorten Johan Sørvig2019-05-141-2/+0
| | | | | | | | | | Install one browser window resize handler instead of per-canvas resize handlers, which avoids having to uninstall on QScreen destruction. Task-number: QTBUG-75463 Change-Id: I8345262a906ed735f8e9e146f1e963f515cf0d25 Reviewed-by: Lorn Potter <lorn.potter@gmail.com>
* wasm: fix touchpoint handlingLorn Potter2019-03-151-0/+3
| | | | | | | | | | | | emscripten sends a touchstart event for every touch point when a new touch point happens, so this makes them moved or stationary if already known. This allows QtQuick PinchArea to work. Task-number: QTBUG-72214 Change-Id: I8e7c0cd2d78b07cfeae21491846cc31092359050 Reviewed-by: Morten Johan Sørvig <morten.sorvig@qt.io>
* wasm: support rendering to multiple canvasesMorten Johan Sørvig2019-03-081-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* wasm: send mouse release to proper windowLorn Potter2018-12-161-0/+1
| | | | | | | | | | | | | | | | | When the mouse is released, it gets the current window to send the event to from the pointer position. If the release happens out of the browser viewport, that window is null and the release event essentially gets ignored. This change keeps the last known QWindow object to send the event to until the release. Also replace hardcoded emscripten events with enum names.
