* wasm: don’t leak QWasmScreen member variablesMorten Sørvig2021-06-221-2/+2

* wasm: detect canvas resize using ResizeObserver APIMorten Johan Sørvig2020-08-111-0/+3
| | | | | | | | | | | | | The ResizeObserver API is now available on the major desktop browsers (Safari, Chrome, Firefox), and can be used to handle canvas resize. (Previously, we got a callback on viewport resize only) Pick-to: 5.15 Change-Id: I8737285416bef70641f90da793c85efcb24f3623 Reviewed-by: Lorn Potter <lorn.potter@gmail.com>
* wasm: store and pass canvases as emscripten::valMorten Johan Sørvig2020-02-121-2/+5
| | | | | | | | | | | | | | | | | | | | Store and pass canvases as emscripten::val instead of a QString containing the element id. This simplifies code which interacts with the canvas using the emscripten::val API, by removing the need to look up with getElementById. The Emscripten C event API does not accept emscripten::val, and using the element id is still needed here. emscripten::val does not provide a hash key suitable for use with QHash, but does provide an equality-compare in the form of val::equals(). Change the canvas->screen mapping code to use a QVector instead of a QHash. Change-Id: I1dbdbbc8fb06bb869031f1500e83ae2d64780a7f Reviewed-by: Lorn Potter <lorn.potter@gmail.com>

| * wasm: controlled screen destructionMorten Johan Sørvig2019-05-141-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | Freeing OpenGL resources requires a current context, which (on wasm) requires a screen. Add a destroy() functions to QWasmScreen, QWasmCompositor, QWasmWindow, and QWasmBackingStore which facilitates OpenGL cleanup before we start deleting screen objects.

* | wasm: support setting the font DPI from JSMorten Johan Sørvig2019-05-131-0/+1
|/ | | | | | | | | | | | | | | We have not really been able to determine what the default DPI should be, so make it configurable with API on qtloader.js: qtLoader.setFontDpi(72); Also lowers the default DPI to the standard value of 96 (down from Qt default 100).

* wasm: support rendering to multiple canvasesMorten Johan Sørvig2019-03-081-9/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
