// QtLoader provides javascript API for managing Qt application modules.
|
||||||
|
//
|
||||||
|
// QtLoader provides API on top of Emscripten which supports common lifecycle
|
||||||
|
// tasks such as displaying placeholder content while the module downloads,
|
||||||
|
// handing application exits, and checking for browser wasm support.
|
||||||
|
//
|
||||||
|
// There are two usage modes:
|
||||||
|
// * Managed: QtLoader owns and manages the HTML display elements like
|
||||||
|
// the loader and canvas.
|
||||||
|
// * External: The embedding HTML page owns the display elements. QtLoader
|
||||||
|
// provides event callbacks which the page reacts to.
|
||||||
|
//
|
||||||
|
// Managed mode usage:
|
||||||
|
//
|
||||||
|
// var config = {
|
||||||
|
// containerElements : [$("container-id")];
|
||||||
|
// }

||||||

// var qtLoader = QtLoader(config);

|

|

// var config = {

// canvasElements : [$("canvas-id")],
