Description
#2 from QTBUG-67592
in some cases we would like to retrieve the result of a slot synchronously so I propose to wrap the slot invocation in a Promise when there is no callback so that client code may use 'await'
function addMethod(methodData) {
...
if (callback) {
webChannel.exec({
"type": QWebChannelMessageTypes.invokeMethod,
"object": object.__id__,
"method": methodIdx,
"args": args
}, function (response) {
if (response !== undefined) {
var result = object.unwrapQObject(response);
(callback)(result);
}
});
} else {
var promise = new Promise(function (resolve, reject) {
webChannel.exec({
"type": QWebChannelMessageTypes.invokeMethod,
"object": object.__id__,
"method": methodIdx,
"args": args
}, function (response) {
if (response !== undefined) {
var result = object.unwrapQObject(response);
resolve(result);
} else {
resolve();
}
});
});
return promise;
}
}
