* speedup js binding generation + minor js related fixes
* support for private quickcontrols2 classes with `QT_GEN_QUICK_EXTRAS=true`
* fix for static linux deployment issue
* minor example updates
* fix for minor qtmoc docker related issue
These changes introduce two new functions called (*qml.QJSEngine).NewGoType and (*qml.QJSEngine).ToGoType, that can be used (similiar to how core.NewQVariant1 and (*core.QVariant).ToGoType can be used) to convert Go objects and functions to *qml.QJSValues and vice versa.
This allows for a more natural communication between Go and Qml/JS and makes it possible to simply pass a Go structs to Qml/JS and then call Go methods on that object.
For this to work, the object passed to Qml/JS needs to implement the `Pointer() unsafe.Pointer` and `SetPointer(unsafe.Pointer)` functions atm.
Which means, since all Qt classes already implement these functions, that you can now use the whole binding from Qml/JS as well and theoretically create a full Qt application inside an QJSEngine as well. A few example applications almost entirely written in JS can be found here: https://github.com/therecipe/examples/tree/master/js/
Furthermore, the `widgets_playground` example (https://github.com/therecipe/widgets_playground) now fully works on desktop and mobile targets as well.
other changes:
* core.NewQVariant1 and (*core.QVariant).ToGoType now recognize json tags
* workaround for qtmoc issue related to named imports
* speed-up go module android docker deployments
* fix webengine related qtdeploy bug on macOS
* fix int overflow issue for arm docker images
* fix js docker images
* new docker images to make it easier to deploy to "embedded" armv6/armv7/arm64 systems such as Raspberry Pi, Orange Pi, Banana Pi, BeagleBone, BeagleBoard, ODROID, Asus Tinker Board, ...
* fixes for Go 1.13 + retain go module 1.12 GOPATH behavior for internal/examples
* update docker images to 5.13.0
* new docker images (windows_64_shared_512, linux_512, darwin_512)
* update examples to match the Qt 5.13 api
* bump android minSdkVersion to 21 (5.0 / lollipop)
* bump OpenSSL version for android docker deployments to 1.1.1a
* let the binding use the 513 env by default
you can use QT_VERSION=5.12.0 and/or QT_API=5.12.0 to keep the binding backward compatible with your code
just setting QT_API=5.12.0 alone should also be sufficient to keep docker deployments working
if you did install an official Qt version then just set the correct QT_VERSION and procede as usual
* various minor fixes and cleanups
* support interface{} returns for js/wasm
* fix android builds on darwin
* support for the virtualkeyboard module
* fixes for docker image builds
* cleanup callback handling
* fix possible moc memory leaks
* new virtualkeyboard examples
* js/wasm GOCACHE fix for Go 1.12+
* make use of the official Go 1.12 wasm build and replace js.NewCallback with js.FuncOf
* update docker images to Go 1.12.4
* revive raspberry images
* fix raspberry related bundling issue
* add the multimedia module to the raspberry images
* fix raspberry related QT_API issue
* remove unecessary *char to []byte copy overhead in some unlikely cases
* fix Qt install script
* initial partially support for Felgo (former V-Play) on darwin
* fix charts/audio example and darwin
* fix common/widgets_demo example on iOS (issue #451)
* fix widgets/renderer memory leak
* fix possible QT_PKG_CONFIG + QT_VERSION race condition
* fix static linux docker image
this is the start of series of a few incrementally breaking changes, mainly started to remove the uneccessary conversion of []byte to string or vice versa on your side
the few functions accepting *string will also be affected the future
functions generated by qtmoc are not affected
1. the qt api changed in various places
2. dropped the "_minimal" suffix for the deployment folders
3. to keep using older versions of Qt (5.7.1 for example), one would
now need to explicit export "QT_VERSION=5.7.1" and also
"QT_DIR=/path/to/Qt5.7.1"
