All Implemented Interfaces:
  `Animation, Editable, StyleListener, Iterable<Component>`

public class Sheet extends Container

A light-weight dialog that slides up from the bottom of the screen on mobile devices. Sheets include a "title" bar, with a back/close button, a title label, and a "commands container" (`#getCommandsContainer()`) which allows you to insert your own custom components (usually buttons) in the upper right.

Custom content should be placed inside the content pane which can be retrieved via `#getContentPane()`

Usage

The general usage is to create new Sheet instance (or subclass), then call `#show()` to make it appear over the current form. If a different sheet that is currently being displayed, then calling `#show()` will replace it.

Inter-Sheet Navigation

The `java.lang.String)` constructor can take another Sheet object as a parameter, which will act as a "parent" sheet (`#getParentSheet()`. If the parent sheet is not null, then this sheet will have a "Back" button instead of a "Close" button. THe "Back" button will navigate back to the parent sheet.

When navigating between sheets, the sheet will be resized with a smooth slide animation to the preferred height of the destination sheet.

Example

    `public void start() {
    if(current != null){
    current.show();
    return;`
    Form hi = new Form("Hi World", new BorderLayout());

    Button b = new Button("Open Sheet");
    b.addActionListener(e->{
    new MySheet(null).show();

    });
    hi.add(BorderLayout.NORTH, b);
    hi.show();
    }

    private class MySheet extends Sheet {
    MySheet(Sheet parent) {
    super(parent, "My Sheet");
    Container cnt = getContentPane();
    cnt.setLayout(BoxLayout.y());
    Button gotoSheet2 = new Button("Goto Sheet 2");
    gotoSheet2.addActionListener(e->{
    new MySheet2(this).show(300);
    });
    cnt.add(gotoSheet2);
    for (String t : new String[]{"Red", "Green", "Blue", "Orange"}) {
    cnt.add(new Label(t));
    }
    }
    }

    private class MySheet2 extends Sheet {
    MySheet2(Sheet parent) {
    super(parent, "Sheet 2");
    Container cnt = getContentPane();
    cnt.setLayout(BoxLayout.y());
    cnt.setScrollableY(true);
    for (int i=0; iVideo Sample

  - ### Sheet

    public Sheet(Sheet parent, String title)

    Creates a new sheet with the specified parent and title.

    ###### Parameters

    - `parent`: Optional parent sheet. If non-null, then this sheet will have a "back" button instead of a "close" button. The "back" button will return to the parent sheet.

    - `title`: The title to display in the title bar of the sheet.

    - `uiid`: @param uiid Optional UIID for the sheet. If non-null, then the Sheet's uiid will be uiid, the title label's UIID will be uiid + "Title", the title bar's UIID will be uiid + "TitleBar", and the back/close button's UIID will be uiid + "BackButton".

- ## Method Details

  - ### isSheetVisibleAt

    public static boolean isSheetVisibleAt(int x, int y)

  - ### getCurrentSheet

    public static Sheet getCurrentSheet()

    Gets the current sheet on the current form or null if no sheet is currently being displayed.

    ###### Returns

    The current sheet or null.

    ###### Since

    7.0

  - ### findContainingSheet

    public static Sheet findContainingSheet(Component cmp)

    Finds Sheet containing this component if it is currently part of a Sheet.

    ###### Parameters

    - `cmp`: The component to check.

    ###### Returns

    The sheet containing the component, or null if it is not on a sheet.

    ###### Since

    7.0

  - ### isAllowClose

    public boolean isAllowClose()

    Checks whether the user is allowed to close this sheet.

    ###### Returns

    True if user can close the sheet.

  - ### setAllowClose

    public void setAllowClose(boolean allowClose)

    Sets whether the user is able to close this sheet. Default is true. If you set this value to false, then there will be no close button, and pressing outside of the sheet will have no effect.

    Child sheets will assume the settings of the parent. The back button will still work, but the top level sheet will not include a close button.

    ###### Parameters

    - `allowClose`: True to allow user to close the sheet. False to prevent it.

    ###### Since

    7.0

  - ### isSwipeToDismissEnabled

    Checks whether this sheet can be dismissed by swiping it toward the edge of the screen (e.g. swiping down for a south-positioned sheet).

    ###### Returns

    True if swipe-to-dismiss is enabled.

    ###### Since

    8.0

  - ### setSwipeToDismissEnabled

    public void setSwipeToDismissEnabled(boolean swipeToDismissEnabled)

The gesture is also subject to `isAllowClose()`; if `allowClose` is false the gesture is disabled regardless of this flag.

    ###### Parameters

    - `swipeToDismissEnabled`: True to enable the swipe-to-dismiss gesture, false to disable it.

    ###### Since

    8.0

  - ### getContentPane

    public Container getContentPane()

    Hides the back button.

  - ### showBackButton

    public void showBackButton()
    Shows the back button.

  - ### getCommandsContainer

    public Container getCommandsContainer()
    Gets the container that is rendered on the top right bar of the sheet. Use this to add buttons and other content you wish to appear in the title bar. Best not to overload this with too many things.

  - ### getTitle

    public String getTitle()

    Gets the title text displayed in the default title label.

    ###### Returns

    The sheet title text.

    ###### Since

    8.0

  - ### setTitle

    public void setTitle(String title)

    Sets the title text displayed in the default title label.

    ###### Since

    8.0

  - ### getTitleComponent

    public Component getTitleComponent()

    The current title component.

    ###### Since

    8.0

  - ### setTitleComponent

    public void setTitleComponent(Component cmp)

    Sets the title component rendered in the center of the title bar.

    This allows for custom title layouts such as including an image above the title text. If `null` is passed, the default title label is restored.

    ###### Parameters

    - `cmp`: The component to use for the title area, or `null` to restore the default title label.

    ###### Since

    8.0

  - ### show

    public void show()

    Shows the sheet with the default (300ms) transition duration.

    ###### See also

    - #show(int)

  - ### showForResult

    public <T> AsyncResource<T> showForResult()

    Shows the sheet and returns an `AsyncResource` that will be completed when the sheet finishes -- either with `#finish(Object)` carrying a chosen value, or with `null` when the sheet is dismissed via back/swipe.

    Lets sheets be used as inline confirmation dialogs / pickers without wiring up `addCloseListener` + state-shared variables:

        PickerSheet sheet = new PickerSheet();
        sheet.<String>showForResult().ready(new SuccessCallback<String>() {
            public void onSuccess(String picked) {
                if (picked != null) handle(picked);
            }
        });

    The result type is supplied at the call site; use `Sheet#finish(Object)` internally to complete it. The cast is unchecked at runtime -- pick a type you control inside the sheet.

    ###### Since 8.0

    ###### Since 8.0

  - ### show

    public void show(int duration)
