Methods

Update Background

When this method is executed, as well as when the title bar is created, it is checked whether the color is light or dark, so that the color of the icons adapts to the background of the title bar.

titlebar.updateBackground(new Color(new RGBA(0, 0, 0, .7)));

To assign colors you can use the following options: Color.fromHex(), new Color(new RGBA(r, g, b, a)), new Color(new HSLA(h, s, l, a)), new Color(new HSVA(h, s, v, a)) or Color.BLUE, Color.RED, etc.

Update Title

This method updated the title of the title bar, If you change the content of the title tag, you should call this method for update the title.

document.title = 'My new title';
titlebar.updateTitle();

// Or you can do as follows and avoid writing document.title
titlebar.updateTitle('New Title');

if this method is called and the title parameter is added, the title of the document is changed to that of the parameter.

titlebar.updateIcon('./images/my-icon.svg');
