      public class Layout
      extends Canvas
      implements HasMembersChangedHandlers

  Arranges a set of "member" Canvases in horizontal or vertical stacks, applying a layout policy to determine member heights and widths.

  A Layout manages a set of "member" Canvases initialized via the "members" property. Layouts can have both "members", which are managed by the Layout, and normal Canvas children, which are unmanaged.

  Rather than using the Layout class directly, use the HLayout, VLayout, HStack and VStack classes, which are subclasses of Layout preconfigured for horizontal or vertical stacking, with the "fill" (VLayout) or "none" (VStack) `policies` already set.

  Layouts and Stacks may be nested to create arbitrarily complex layouts.

  To show a resizer bar after (to the right or bottom of) a layout member, set showResizeBar to true on that member component (not on the HLayout or VLayout). Resizer bars override membersMargin spacing.

  Like other Canvas subclasses, Layout and Stack components may have % width and height values. To create a dynamically-resizing layout that occupies the entire page (or entire parent component), set width and height to "100%".

    - #### setCanDropComponents

          public void setCanDropComponents(java.lang.Boolean canDropComponents)
                                    throws java.lang.IllegalStateException

      Layouts provide a default implementation of a drag and drop interaction. If you set `canAcceptDrop`:true and `canDropComponents:true` on a Layout, when a droppable Canvas (`canDrop:true` is dragged over the layout, it will show a dropLine (a simple insertion line) at the drop location.

      When the drop occurs, the dragTarget (obtained using `EventHandler.getDragTarget()`) is added as a member of this layout at the location shown by the dropLine (calculated by `Layout.getDropPosition()`). This default behavior allows either members or external components that have `canDragReposition` (or `canDrag`) and `canDrop` set to `true` to be added to or reordered within the Layout.

      You can control the thickness of the dropLine via `dropLineThickness` and you can customize the style using css styling in the skin file (look for .layoutDropLine in skin_styles.css for your skin).

      If you want to dynamically create a component to be added to the Layout in response to a drop event you can do so as follows:

            isc.VLayout.create({
              ...various layout properties...
              canDropComponents: true,
              drop : function () {
                // create the new component
                var newMember = isc.Canvas.create();
                // add to the layout at the current drop position
                // (the dropLine will be showing here)
                this.addMember(newMember, this.getDropPosition());
                // hide the dropLine that was automatically shown
                // by builtin Smart GWT methods
                this.hideDropLine();
              }
            });

      If you want to completely suppress the builtin drag and drop logic, but still receive drag and drop events for your own custom implementation, set `canAcceptDrop` to `true` and `canDropComponents` to `false` on your Layout.

      Note : This is an advanced setting

      Parameters:
        `canDropComponents` - Default value is true
      Throws:
        `java.lang.IllegalStateException` - this property cannot be changed after the component has been created
      See Also:
        `Dragdrop overview and related methods`

    - #### getCanDropComponents

          public java.lang.Boolean getCanDropComponents()

                var newMember = isc.Canvas.create();
                // add to the layout at the current drop position
                // (the dropLine will be showing here)
                this.addMember(newMember, this.getDropPosition());
                // hide the dropLine that was automatically shown
                // by builtin Smart GWT methods
                this.hideDropLine();
              }
            });

      Minimum size, in pixels, below which flexible-sized members should never be shrunk, even if this requires the Layout to overflow.

      Does not apply to members given a fixed size in pixels - such members will never be shrunk below their specified size in general.

      Returns:
        int

    - #### setOverflow

          public void setOverflow(Overflow overflow)

      Normal `Overflow` settings can be used on layouts, for example, an overflow:auto Layout will scroll if members exceed its specified size, whereas an overflow:visible Layout will grow to accommodate members.
      Overrides:
        `setOverflow` in class `Canvas`
      Parameters:
        `overflow` - Default value is "visible"
      See Also:
        `Sizing overview and related methods`

    - #### getOverflow

          public Overflow getOverflow()

      Normal `Overflow` settings can be used on layouts, for example, an overflow:auto Layout will scroll if members exceed its specified size, whereas an overflow:visible Layout will grow to accommodate members.
      Overrides:

    - #### setPaddingAsLayoutMargin

          public void setPaddingAsLayoutMargin(java.lang.Boolean paddingAsLayoutMargin)

      If this widget has padding specified (as `this.padding` or in the CSS style applied to this layout), should it show up as space outside the members, similar to layoutMargin?

      If this setting is false, padding will not affect member positioning (as CSS padding normally does not affect absolutely positioned children). Leaving this setting true allows a designer to more effectively control layout purely from CSS.

      Note that `layoutMargin` if specified, takes precedence over this value.

      Note : This is an advanced setting

      Parameters:
        `paddingAsLayoutMargin` - Default value is true

    - #### getPaddingAsLayoutMargin

          public java.lang.Boolean getPaddingAsLayoutMargin()

      If this widget has padding specified (as `this.padding` or in the CSS style applied to this layout), should it show up as space outside the members, similar to layoutMargin?

      If this setting is false, padding will not affect member positioning (as CSS padding normally does not affect absolutely positioned children). Leaving this setting true allows a designer to more effectively control layout purely from CSS.

      Note that `layoutMargin` if specified, takes precedence over this value.

      Returns:
        Boolean

      If `this.showDragPlaceHolder` is true, this defaults object determines the default appearance of the placeholder displayed when the user drags a widget out of this layout.
      Default value for this property sets the placeholder `styleName` to `"layoutPlaceHolder"`
      To modify this object, use Class.changeDefaults()
      Parameters:
        `placeHolderDefaults` - Default value is null
      Throws:
        `java.lang.IllegalStateException` - this property cannot be changed after the component has been created
      See Also:
        `Dragdrop overview and related methods`

    - #### setPlaceHolderProperties

          public void setPlaceHolderProperties(Canvas placeHolderProperties)

    - #### getResizeBar

          public Splitbar getResizeBar()

      Note : This API is non-functional (always returns null) and exists only to make you aware that this MultiAutoChild exists. See `Using AutoChildren` for details.

      A MultiAutoChild created to resize members of this `Layout`.

      A resize bar will be created for any member of this `Layout` that has `showResizeBar` set to `true`. Resize bars will be instances of the class specified by `resizeBarClass` by default, and will automatically be sized to the member's breadth, and to the thickness specified by `resizeBarSize`.

      To customize the appearance or behavior of resizeBars within some layout a custom resize bar class can be created by subclassing `Splitbar` or `ImgSplitbar` and setting `resizeBarClass` or `resizeBarConstructor` to this custom class. Alternatively, `Canvas.setAutoChildProperties(java.lang.String, com.smartgwt.client.widgets.Canvas)` may be called to set resizeBar properties:

                final Splitbar resizeBarProperties = new Splitbar();
                //...
                layout.setAutoChildProperties("resizeBar", resizeBarProperties);

      See `AutoChildUsage` for more information.

      If you create a custom resize bar class in Java, enable `Reflection` to allow it to be used.

      Alternatively, you can use the SmartClient class system to create a simple SmartClient subclass of either `Splitbar` or `ImgSplitbar` for use with this API - see the `Skinning Guide` for details.

      The built-in `Splitbar` class supports drag resizing of its target member, and clicking on the bar with a mouse to collapse/uncollapse the target member.

      Returns:
        null

    - #### setDefaultProperties

          public static void setDefaultProperties(Layout layoutProperties)

      Class level method to set the default properties of this class. If set, then all existing and subsequently created instances of this class will automatically have default properties corresponding to the properties set on the SmartGWT class instance passed to this function before its underlying SmartClient JS object was created. This is a powerful feature that eliminates the need for users to create a separate hierarchy of subclasses that only alter the default properties of this class. Can also be used for skinning / styling purposes.

      Note: This method is intended for setting default attributes only and will affect all instances of the underlying class (including those automatically generated in JavaScript). This method should not be used to apply standard EventHandlers or override methods for a class - use a custom subclass instead. Calling this method after instances have been created can result in undefined behavior, since it bypasses any setters and a class instance may have already examined a particular property and not be expecting any changes through this route.

      Parameters:
        `layoutProperties` - properties that should be used as new defaults when instances of this class are created
