Example of usage

This JavaScript makes sure the DocuVieware control is properly loaded and initialized and then subscribes to the event on load to display the fullscreen state in the console.

function RegisterOnFullscreenModeChangedOnDocuViewareAPIReady() {
    if (typeof DocuViewareAPI !== "undefined" && DocuViewareAPI.IsInitialized("DocuVieware1")) {
        DocuViewareAPI.RegisterOnFullscreenModeChanged("DocuVieware1", function (state) { console.log(state); });
    }
    else {
        setTimeout(function () { RegisterOnFullscreenModeChangedOnDocuViewareAPIReady() }, 10);
    }
}
document.addEventListener("DOMContentLoaded", function () {
    RegisterOnFullscreenModeChangedOnDocuViewareAPIReady();
}, false);
