*Panels are, by virtue of their inheritance from {@link Ext.Container}, capable * of being configured with a {@link Ext.Container#layout layout}, and containing child Components.
*When either specifying child {@link Ext.Component#items items} of a Panel, or dynamically {@link Ext.Container#add adding} Components * to a Panel, remember to consider how you wish the Panel to arrange those child elements, and whether * those child elements need to be sized using one of Ext's built-in
*{@link Ext.Container#layout layout}schemes. By * default, Panels use the {@link Ext.layout.ContainerLayout ContainerLayout} scheme. This simply renders * child components, appending them one after the other inside the Container, and does not apply any sizing * at all.A Panel may also contain {@link #bbar bottom} and {@link #tbar top} toolbars, along with separate * {@link #header}, {@link #footer} and {@link #body} sections (see {@link #frame} for additional * information).
*Panel also provides built-in {@link #collapsible expandable and collapsible behavior}, along with * a variety of {@link #tools prebuilt tool buttons} that can be wired up to provide other customized * behavior. Panels can be easily dropped into any {@link Ext.Container Container} or layout, and the * layout and rendering pipeline is {@link Ext.Container#add completely managed by the framework}.

* An example of specifying a custom icon class would be something like: *
// specify the property in the config for the class:
...
iconCls: 'my-icon'
// css class that specifies background image to be used as the icon image:
.my-icon { background-image: url(../images/my-icon.gif) 0 6px no-repeat !important; }
tools.<tool-type>
* Each tool config may contain the following properties: *
x-tool-<tool-type> to the
* resulting tool Element. Ext provides CSS rules, and an icon sprite containing images for the tool types listed below.
* The developer may implement custom tools by supplying alternate CSS rules and background images:
* toggle (Created by default when {@link #collapsible} is true) close minimize maximize restore gear pin unpin right left up down refresh minus plus help search save printNote that, apart from the toggle tool which is provided when a panel is collapsible, these * tools only provide the visual button. Any required functionality must be provided by adding * handlers that implement the necessary behavior.
*Example usage:
*
tools:[{
id:'refresh',
qtip: 'Refresh form Data',
// hidden:true,
handler: function(event, toolEl, panel){
// refresh logic
}
},
{
id:'help',
qtip: 'Get Help',
handler: function(event, toolEl, panel){
// whatever
}
}]
For the custom id of 'help' define two relevant css classes with a link to
* a 15x15 image:
.x-tool-help {background-image: url(images/help.png);}
.x-tool-help-over {background-image: url(images/help_over.png);}
// if using an image sprite:
.x-tool-help {background-image: url(images/help.png) no-repeat 0 0;}
.x-tool-help-over {background-position:-15px 0;}
A Template used to create {@link #tools} in the {@link #header} Element. Defaults to:
new Ext.Template('<div class="x-tool x-tool-{id}"> </div>')This may may be overridden to provide a custom DOM structure for tools based upon a more * complex XTemplate. The template's data is a single tool configuration object (Not the entire Array) * as specified in {@link #tools}. In the following example an <a> tag is used to provide a * visual indication when hovering over the tool:
var win = new Ext.Window({
tools: [{
id: 'download',
href: '/MyPdfDoc.pdf'
}],
toolTemplate: new Ext.XTemplate(
'<tpl if="id==\'download\'">',
'<a class="x-tool x-tool-pdf" href="{href}"></a>',
'</tpl>',
'<tpl if="id!=\'download\'">',
'<div class="x-tool x-tool-{id}"> </div>',
'</tpl>'
),
width:500,
height:300,
closeAction:'hide'
});Note that the CSS class 'x-tool-pdf' should have an associated style rule which provides an * appropriate background image, something like:
a.x-tool-pdf {background-image: url(../shared/extjs/images/pdf.gif)!important;}
true to hide the expand/collapse toggle button when {@link #collapsible} == true,

For custom drag/drop implementations, an Ext.Panel.DD config could also be passed

* moves a proxy Element around in place of the Panel's element, but provides no other behaviour
* during dragging or on drop. It is a subclass of {@link Ext.dd.DragSource}, so behaviour may be
* added by implementing the interface methods of {@link Ext.dd.DragDrop} e.g.:
*
new Ext.Panel({
title: 'Drag me',
x: 100,
y: 100,
renderTo: Ext.getBody(),
floating: true,
frame: true,
width: 400,

// Config option of Ext.Panel.DD class.
// It's a floating Panel, so do not show a placeholder proxy in the original position.
insertProxy: false,
// Called for each mousemove event while dragging the DD object.
onDrag : function(e){
// Record the x,y position of the drag proxy so that we can
// position the Panel at end of drag.
var pel = this.proxy.getEl();
this.x = pel.getLeft(true);
this.y = pel.getTop(true);
// Keep the Shadow aligned if there is one.
var s = this.panel.getEl().shadow;
if (s) {
s.realign(this.x, this.y, pel.getWidth(), pel.getHeight());
}
},
// Called on the mouseup event.
endDrag : function(e){
this.panel.setPosition(this.x, this.y);
}
}
}).show();
false). An important note when using the disabled
* config on panels is that IE will often fail to initialize the disabled mask element correectly if
* the panel's layout has not yet completed by the time the Panel is disabled during the render process.
* If you experience this issue, you may need to instead use the {@link #afterlayout} event to initialize
* the disabled state:
*
new Ext.Panel({
...
listeners: {
'afterlayout': {
fn: function(p){
p.disable();
},
single: true // important, as many layouts can occur
}
}
});
true to use height:'auto', false to use fixed height (defaults to false).
* Note: Setting autoHeight: true means that the browser will manage the panel's height
* based on its contents, and that Ext will not manage it at all. If the panel is within a layout that
* manages dimensions (fit, border, etc.) then setting autoHeight: true
* can cause issues with scrolling and will not generally work as expected since the panel will take
* on the height of its contents rather than the height required by the Ext layout.
