* wasm: saveFile(): copy data before returningMorten Sørvig2024-06-181-1/+2
| | | | | | | | | | | | | | | | | | | | | | Make saveFile(char *, size) make an immediate copy of the data also for the case where we use a save file dialog. Previously it would make a copy after the file dialog was closed, but at that point the content pointer may be stale if the calling code did not keep it alive. This makes the behavior for the two save code paths be identical: a copy of the data will be made right away, before the function returns. This is also the only behavior which makes sense, since the function has no way of communicating to the caller when it is done with the data.

| | | | | | | | | | | | File filter was not properly processed when using LocalFileAPI. The QtFormat->AcceptList conversion was happening twice, resulting in erronous types.

* Copy memory to buffer when saving files on wasm with threading onMikolaj Boc2023-04-251-4/+28
| | | | | | | | | | | | | | | wasm heap uses a shared array buffer, which cannot be fed to FileSystemWritableFileStream.write due to security limitations. Heap memory has to be copied to a temporary buffer for the operation to succeed. This is only done if __EMSCRIPTEN_SHARED_MEMORY__ is on to optimize the non-threading path.

* wasm: align QWasmLocalFileAccess API with 6.4Morten Sørvig2022-12-282-8/+86
| | | | | | | | | | | | | | | | | | | | | | This API is undocumented, but by keeping unchanged makes it easier to use from external projects. openFile(): Copy the accept/filter list parsing function from 6.4. It makes sense to implement this behind the API, so that user code doesn't have to reimplement it. saveFile(): Slightly more complicated; the new variant which takes a QByteArray is better since the implementation can then keep a reference to the data for as long as it needs, without copying the data. Add the const char * variant to keep existing code going for now. Adjust the calling code in widgets.

| | | | | | | | | | | | | As a preparatory measure for using showXFilePicker, the Qt file filter has to be transformed to the format used by the showXFilePicker (sXFP) options.

* wasm: add local file access private APIMorten Johan Sørvig2019-02-073-0/+250
Access to the local file system is restricted by the Web sandbox, and a separate API an implementation is needed to facilitate this for Qt applications. This adds a private asynchronous callback-based C++ API for opening a file dialog and reading file content. The implementation uses a file input html element to show a file dialog, and then the uses the native File and FileReader APIs to read the selected file(s).
