```
Panel is a container that has specific functionality and structural components that make it the perfect building block for application-oriented user interfaces. The Panel contains bottom, top, and foot toolbars, along with separate header, footer and body sections. It also provides built-in collapsible, closable, maximizable, and minimizable behavior, along with a variety of pre-built tool buttons that can be wired up to provide other customized behavior. Panels can be easily embedded into any kind of ZUL component that is allowed to have children or layout component. Panels also provide specific features like float and move. Unlike Window, Panels can only be floated and moved inside its parent node, which is not using zk.setVParent() function at client side. In other words, if Panel's parent node is an relative position, the floated panel is only inside its parent, not the whole page. The second difference of Window is that Panel is not an independent ID space (by implementing IdSpace), so the ID of each child can be used throughout the panel.
Events:
onMove, onOpen, onZIndex, onMaximize, onMinimize, and onClose.

Default getZclass(): z-panel.

    Description copied from interface: Component
    
    Sets whether this component is visible.
    
    Specified by:
    
    setVisible in interface Component
    
    Overrides:
    
    setVisible in class AbstractComponent
    
    Returns:
    
    the previous visibility
  - setFloatable
```
public void setFloatable(boolean floatable)
```
    Sets whether to float the panel to display it inline where it is rendered.
    Note that by default, setting floatable to true will cause the panel to display at default offsets, which depend on the offsets of the embedded panel from its element to document.body -- because the panel is absolute positioned, the position must be set explicitly by HtmlBasedComponent.setTop(String) and HtmlBasedComponent.setLeft(String). Also, when floatable a panel you should always assign a fixed width, otherwise it will be auto width and will expand to fill to the right edge of the viewport.
  - isMaximized
```
public boolean isMaximized()
```
    Returns whether the panel is maximized.
    
    Specified by:
    
    isMaximized in interface Framable
  - setMaximized
```
public void setMaximized(boolean maximized)
```
    Sets whether the panel is maximized, and then the size of the panel will depend on it to show a appropriate size. In other words, if true, the size of the panel will count on the size of its offset parent node whose position is absolute (by isFloatable()) or its parent node. Otherwise, its size will be original size. Note that the maximized effect will run at client's sizing phase not initial phase.
    Default: false.
    
    Throws:
    
    UiException - if isMaximizable() is false.
  - isMaximizable
```
public boolean isMaximizable()
```
    Returns whether to display the maximizing button and allow the user to maximize the panel.
    Default: false.
    
    Specified by:
    
    isMaximizable in interface Framable
  - setMaximizable
```
public void setMaximizable(boolean maximizable)
```
    Sets whether to display the maximizing button and allow the user to maximize the panel, when a panel is maximized, the button will automatically change to a restore button with the appropriate behavior already built-in that will restore the panel to its previous size.
    Default: false.
    Note: the maximize button won't be displayed if no title or caption at all.
  - isMinimized
```
public boolean isMinimized()
```
    Returns whether the panel is minimized.
    Default: false.
  - setMinimized
```
public void setMinimized(boolean minimized)
```
    Sets whether the panel is minimized.
    Default: false.
    
    Throws:
    
    UiException - if isMinimizable() is false.
  - isMinimizable
```
public boolean isMinimizable()
```
    Returns whether to display the minimizing button and allow the user to minimize the panel.
    Default: false.
    
    Specified by:
    
    isMinimizable in interface Framable
  - setMinimizable
```
public void setMinimizable(boolean minimizable)
```
    Sets whether to display the minimizing button and allow the user to minimize the panel. Note that this button provides no implementation -- the behavior of minimizing a panel is implementation-specific, so the MinimizeEvent event must be handled and a custom minimize behavior implemented for this option to be useful.
    Default: false.
    Note: the maximize button won't be displayed if no title or caption at all.
    
    See Also:
    
    MinimizeEvent
  - isCollapsible
```
public boolean isCollapsible()

    Specified by:
    
    isCollapsible in interface Framable
  - setCollapsible
```
public void setCollapsible(boolean collapsible)
```
    Sets whether to show a toggle button on the title bar.
    Default: false.
    Note: the toggle button won't be displayed if no title or caption at all.
    Note: onOpen event will be sent when you click the toggle button
  - isClosable
```
public boolean isClosable()
```
    Returns whether to show a close button on the title bar.
    
    Specified by:
    
    isClosable in interface Framable
  - setClosable
```
public void setClosable(boolean closable)
```
    Sets whether to show a close button on the title bar. If closable, a button is displayed and the onClose event is sent if an user clicks the button.
    Default: false.
    You can intercept the default behavior by either overriding onClose(), or listening the onClose event.
    Note: the close button won't be displayed if no title or caption at all.
  - setMinheight

  - setHflex
```
public void setHflex(java.lang.String flex)
```
    Description copied from class: HtmlBasedComponent
    
    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.
    
    Overrides:
    
    setHflex in class HtmlBasedComponent
    
    Parameters:
    
    flex - horizontal flex hint of this component.

public void setVflex(java.lang.String flex)
```
    Description copied from class: HtmlBasedComponent
    
    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.

    Default: null (the default value depends on element).
    HtmlBasedComponent.setZclass(java.lang.String)) will completely replace the default style of a component. In other words, the default style of a component is associated with the default value of HtmlBasedComponent.getZclass(). Once it is changed, the default style won't be applied at all. If you want to perform small adjustments, use HtmlBasedComponent.setSclass(java.lang.String) instead.

```
public void beforeChildAdded(Component newChild,
                             Component refChild)
```
    Description copied from class: AbstractComponent
    
    Default: does nothing.
    
    Specified by:
    
    beforeChildAdded in interface ComponentCtrl
    
    Overrides:
    
    beforeChildAdded in class AbstractComponent
    
    Parameters:
    
    newChild - the child to be added (never null).
    
    refChild - another child component that the new child will be inserted before it. If null, the new child will be the last child.
    
    See Also:
    
    ComponentCtrl.beforeChildAdded(org.zkoss.zk.ui.Component, org.zkoss.zk.ui.Component)
  - insertBefore
```
public boolean insertBefore(Component newChild,
                            Component refChild)
```
    Description copied from interface: Component
    
    Inserts a child before the reference child.
    You could use Component.setParent(org.zkoss.zk.ui.Component) or Component.appendChild(org.zkoss.zk.ui.Component) instead of this method, unless you want to control where to put the child.
    Note: Component.setParent(org.zkoss.zk.ui.Component) always calls back Component.insertBefore(org.zkoss.zk.ui.Component, org.zkoss.zk.ui.Component) and/or Component.removeChild(org.zkoss.zk.ui.Component), while Component.insertBefore(org.zkoss.zk.ui.Component, org.zkoss.zk.ui.Component) and Component.removeChild(org.zkoss.zk.ui.Component) always calls back Component.setParent(org.zkoss.zk.ui.Component), if the parent is changed. Thus, you don't need to override both Component.insertBefore(org.zkoss.zk.ui.Component, org.zkoss.zk.ui.Component) and Component.setParent(org.zkoss.zk.ui.Component), if you want to customize the behavior.
    If you would like to monitor if a component is attached or detached from a page, you could register a desktop listener implementing UiLifeCycle.
    
    Specified by:
    
    insertBefore in interface Component
    
    Overrides:
    
    insertBefore in class AbstractComponent
    
    Parameters:
    
    newChild - the new child to be inserted.
    
    refChild - the child before which you want the new child being inserted. If null, the new child is append to the end.
    
    Returns:
    
    true if newChild is added successfully or moved; false if it already has the specified child and the order doesn't change.
