Windows


A Window is a visual area that floats over the page. You can easily add windows to your UI class:

Window w1 = new Window("Default window");
addWindow(w1); // from UI class

Once the window is added, it will majestically appear on the screen:

You can disable the close button of the window:

Window w2 = new Window("You can't close this window, sorry");
w2.setClosable(false);

Or you can fix the size of the window and ban future size changes:

Window w3 = new Window("You can't resize me, ha-ha");
w3.setWidth("200px");
w3.setHeight("100px");
w3.setResizable(false);

As you can see, sizing is done as usual with the setWidth and setHeight methods.

Usually the content of a window is some kind of layout; however, you can set any component as the window content. Here, we are using a label:

Window w4 = new Window("I have a Label inside");
w4.setContent(new Label("I'm that Label."));

You can also disable window dragging:

Window w5 = new Window(
    "You can't drag me :( but you can close me :)");
w5.setDraggable...
