ECMAScript / Javascript Engine builtin objects are immutable (frozen)

XMLWordPrintable

    • Windows

      As already reported in other issues, multiple external (3rd party) JS libraries are unusable in Qt / QML as they depend on altering (replacing) builtin objects properties / functionalities. This should be possible but results in

      TypeError: Type error

      In our case, it is pdfMake but has already been reported to break the usage of sugar.js (see unresolved QTBUG-55058 and others since Qt 5.7.

      It seems there "once was" an idea to resolve this issue, but did never make it into release and was abandoned.

      Obviously it would greatly improve feasibility of JS oriented projects implemented with Qt / QML, if external JS libraries could be used with less hassle and pain.
