qt-web-utils

Utilities and Helper functions for Qt on the Web.

Utility API

The API is declared in qtwebutils.h and implemented in qtwebutils.cpp. The API is provided in two flavours: as static functions in the qtwebutils namespace for use from C++, and as Q_INVOKABLE functions on QtWebUtils singleton for use from QML

  • toggleFullscreen()

    Toggles the browser in and out of fullscreen mode.

  • enableTabCloseConfirmation(bool enable)

    Eables "unsaved data" confirmation dialog on tab close.

  • loadFileToFileSystem() / saveFileFromFileSystem()

    Loads file from the local file system via file dialog; saves to the in-memory file system provided by Emscripten. See also QFileDialog::getOpenFileContents() in Qt.

  • openBrowserWindow()

Examples

The examples are located in the exampels/ directory and demonstrates how to integrate with the web platform, beyond what the default Qt build does.

Usage: build examples/testapp first, using Qt for WebAssembly. This application contains common code used by the examples. The app should be built in-source (i.e. not using shadow builds).

(in examples/testapp): /path/to/qt-wasm/bin/qt-cmake .
