public abstract class HtmlBasedComponent
extends AbstractComponent
```
A skeletal implementation for HTML based components. It simplifies to implement methods common to HTML based components.
Events:
onClick, onDoubleClick, onRightClick, onDrop, onMouseOver, onMouseOut, onOK, onCacnel, onCtrlKey and onSwipe.

It supports
- getSclass() and getStyle().
- getWidth(), getHeight(), getLeft(), getTop(), getZIndex()
- focus()
Since:

5.0.0 supports onOK event., 5.0.0 supports onCancel event., 5.0.0 supports onCtrlKey event., 6.5.0 supports onSwipe event for tablet.

public void setZclass(java.lang.String zclass)
```
    Sets the ZK Cascading Style class(es) for this component. It usually depends on the implementation of the mold (AbstractComponent.getMold()).
    
    Parameters:

```
public java.lang.String getSclass()
```
    Returns the CSS class.
    Default: null.
    The default styles of ZK components doesn't depend on the value of getSclass(). Rather, setSclass(java.lang.String) is provided to perform small adjustment, e.g., only changing the font size. In other words, the default style is still applied if you change the value of getSclass(), unless you override it. To replace the default style completely, use setZclass(java.lang.String) instead.

  - getStyle
```
public java.lang.String getStyle()
```
    Returns the CSS style.
    Default: null.
  - setStyle
```
public void setStyle(java.lang.String style)
```
    Sets the CSS style.
  - setDraggable
```
public void setDraggable(java.lang.String draggable)
```
    Sets "true" or "false" to denote whether a component is draggable, or an identifier of a draggable type of objects.
    The simplest way to make a component draggable is to set this attribute to true. To disable it, set this to false.
    If there are several types of draggable objects, you could assign an identifier for each type of draggable object. The identifier could be anything but empty.
    
    Parameters:
    
    draggable - "false", "" or null to denote non-draggable; "true" for draggable with anonymous identifier; others for an identifier of draggable.
    Notice that if the parent is DragControl and draggable is null, then it means draggable.
  - getDraggable
```
public java.lang.String getDraggable()
```
    Returns the identifier of a draggable type of objects, or "false" if not draggable (never null nor empty).
  - setDroppable
```
public void setDroppable(java.lang.String droppable)
```
    Sets "true" or "false" to denote whether a component is droppable, or a list of identifiers of draggable types of objects that could be dropped to this component.
    The simplest way to make a component droppable is to set this attribute to true. To disable it, set this to false.
    If there are several types of draggable objects and this component accepts only some of them, you could assign a list of identifiers that this component accepts, separated by comma. For example, if this component accepts dg1 and dg2, then assign "dg1, dg2" to this attribute.
    
    Parameters:
    
    droppable - "false", null or "" to denote not-droppable; "true" for accepting any draggable types; a list of identifiers, separated by comma for identifiers of draggables this component accept (to be dropped in).
  - getDroppable
```
public java.lang.String getDroppable()
```
    Returns the identifier, or a list of identifiers of a droppable type of objects, or "false" if not droppable (never null nor empty).
  - focus
```
public void focus()
```
    Sets focus to this element. If an element does not accept focus, this method has no effect.
  - setFocus
```
public void setFocus(boolean focus)
```
    Sets focus to this element. It is same as focus(), but used to allow ZUML to set focus to particular component.
```
<textbox focus="true"/>
```
    Parameters:
    
    focus - whether to set focus. If false, this method has no effect.
    
    Since:
    
    3.0.5
  - setVflex
```
public void setVflex(java.lang.String flex)
```
    Sets vertical flexibility hint of this component.
    Number flex indicates how this component's container distributes remaining empty space among its children vertically. Flexible component grow and shrink to fit their given space. Flexible components with larger flex values will be made larger than components with lower flex values, at the ratio determined by all flexible components. The actual flex value is not relevant unless there are other flexible components within the same container. Once the default sizes of components in a container are calculated, the remaining space in the container is divided among the flexible components, according to their flex ratios.
    
    Specify a flex value of negative value, 0, or "false" has the same effect as leaving the flex attribute out entirely. Specify a flex value of "true" has the same effect as a flex value of 1.
    
    Special flex hint, "min", indicates that the minimum space shall be given to this flexible component to enclose all of its children components. That is, the flexible component grow and shrink to fit its children components.
    
    Parameters:
    
    flex - the vertical flex hint.

```
public void setHflex(java.lang.String flex)
```
    Sets horizontal flex hint of this component.
    Number flex indicates how this component's container distributes remaining empty space among its children horizontally. Flexible component grow and shrink to fit their given space. Flexible components with larger flex values will be made larger than components with lower flex values, at the ratio determined by all flexible components. The actual flex value is not relevant unless there are other flexible components within the same container. Once the default sizes of components in a container are calculated, the remaining space in the container is divided among the flexible components, according to their flex ratios.
    
    Specify a flex value of negative value, 0, or "false" has the same effect as leaving the flex attribute out entirely. Specify a flex value of "true" has the same effect as a flex value of 1.
    
    Special flex hint, "min", indicates that the minimum space shall be given to this flexible component to enclose all of its children components. That is, the flexible component grow and shrink to fit its children components.
    
    Parameters:
    
    flex - horizontal flex hint of this component.

  - getRenderdefer
```
public int getRenderdefer()
```
    Returns the number of milliseconds before rendering this component at the client.
    Default: -1 (don't wait).
    
    Since:
    
    5.0.2
  - setRenderdefer
```
public void setRenderdefer(int ms)
```
    Sets the number of milliseconds before rendering this component at the client.
    Default: -1 (don't wait).
    This method is useful if you have a sophisticated page that takes long to render at a slow client. You can specify a non-negative value as the render-defer delay such that the other part of the UI can appear earlier. The styling of the render-deferred widget is controlled by a CSS class called z-renderdefer.
    Notice that it has no effect if the component has been rendered at the client.
    
    Parameters:
    
    ms - time to wait in milliseconds before rendering. Notice: 0 also implies deferring the rendering (just right after all others are rendered).
    
    Since:
    
    5.0.2
  - getAction
```
public java.lang.String getAction()
```
    Returns the client-side action (CSA).
    Default: null (no CSA at all)
    
    Since:
    
    5.0.6
  - setAction
```
public void setAction(java.lang.String action)
```
    Sets the client-side action (CSA).
    Default: null (no CSA at all)
    The format:
    action1: action-effect1; action2: action-effect2
    
    Currently, only two actions are show and hide. They are called when the widget is becoming visible (show) and invisible (hide).
    The action effect (action-effect1) is the name of a method defined in zk.eff.Actions, such as show: slideDown; hide: slideUp
    You could specify the effects as follows:
    show: slideDown({duration:1000})
    Security Tips: the action is not encoded and it is OK to embed JavaScript, so, if you want to allow users to specify the action, you have to encode it.
    Note for developers upgraded from ZK 3: CSA's format is different and limited. In additions, it is part of HtmlBasedComponent.
    
    Since:
