15 <div id="cls-Ext.Window"></div>/**
18 * <p>A specialized panel intended for use as an application window. Windows are floated, {@link #resizable}, and
19 * {@link #draggable} by default. Windows can be {@link #maximizable maximized} to fill the viewport,
20 * restored to their prior size, and can be {@link #minimize}d.</p>
21 * <p>Windows can also be linked to a {@link Ext.WindowGroup} or managed by the {@link Ext.WindowMgr} to provide
22 * grouping, activation, to front, to back and other application-specific behavior.</p>
23 * <p>By default, Windows will be rendered to document.body. To {@link #constrain} a Window to another element
24 * specify {@link Ext.Component#renderTo renderTo}.</p>
25 * <p><b>Note:</b> By default, the <code>{@link #closable close}</code> header tool <i>destroys</i> the Window resulting in
26 * destruction of any child Components. This makes the Window object, and all its descendants <b>unusable</b>. To enable
27 * re-use of a Window, use <b><code>{@link #closeAction closeAction: 'hide'}</code></b>.</p>
29 * @param {Object} config The config object
32 Ext.Window = Ext.extend(Ext.Panel, {
33 <div id="cfg-Ext.Window-x"></div>/**
35 * The X position of the left edge of the window on initial showing. Defaults to centering the Window within
36 * the width of the Window's container {@link Ext.Element Element) (The Element that the Window is rendered to).
38 <div id="cfg-Ext.Window-y"></div>/**
40 * The Y position of the top edge of the window on initial showing. Defaults to centering the Window within
41 * the height of the Window's container {@link Ext.Element Element) (The Element that the Window is rendered to).
43 <div id="cfg-Ext.Window-modal"></div>/**
44 * @cfg {Boolean} modal
45 * True to make the window modal and mask everything behind it when displayed, false to display it without
46 * restricting access to other UI elements (defaults to false).
48 <div id="cfg-Ext.Window-animateTarget"></div>/**
49 * @cfg {String/Element} animateTarget
50 * Id or element from which the window should animate while opening (defaults to null with no animation).
52 <div id="cfg-Ext.Window-resizeHandles"></div>/**
53 * @cfg {String} resizeHandles
54 * A valid {@link Ext.Resizable} handles config string (defaults to 'all'). Only applies when resizable = true.
56 <div id="cfg-Ext.Window-manager"></div>/**
57 * @cfg {Ext.WindowGroup} manager
58 * A reference to the WindowGroup that should manage this window (defaults to {@link Ext.WindowMgr}).
60 <div id="cfg-Ext.Window-defaultButton"></div>/**
61 * @cfg {String/Number/Component} defaultButton
62 * <p>Specifies a Component to receive focus when this Window is focussed.</p>
63 * <p>This may be one of:</p><div class="mdetail-params"><ul>
64 * <li>The index of a footer Button.</li>
65 * <li>The id of a Component.</li>
66 * <li>A Component.</li>
69 <div id="cfg-Ext.Window-onEsc"></div>/**
70 * @cfg {Function} onEsc
71 * Allows override of the built-in processing for the escape key. Default action
72 * is to close the Window (performing whatever action is specified in {@link #closeAction}.
73 * To prevent the Window closing when the escape key is pressed, specify this as
74 * Ext.emptyFn (See {@link Ext#emptyFn}).
76 <div id="cfg-Ext.Window-collapsed"></div>/**
77 * @cfg {Boolean} collapsed
78 * True to render the window collapsed, false to render it expanded (defaults to false). Note that if
79 * {@link #expandOnShow} is true (the default) it will override the <tt>collapsed</tt> config and the window
80 * will always be expanded when shown.
82 <div id="cfg-Ext.Window-maximized"></div>/**
83 * @cfg {Boolean} maximized
84 * True to initially display the window in a maximized state. (Defaults to false).
87 <div id="cfg-Ext.Window-baseCls"></div>/**
88 * @cfg {String} baseCls
89 * The base CSS class to apply to this panel's element (defaults to 'x-window').
92 <div id="cfg-Ext.Window-resizable"></div>/**
93 * @cfg {Boolean} resizable
94 * True to allow user resizing at each edge and corner of the window, false to disable resizing (defaults to true).
97 <div id="cfg-Ext.Window-draggable"></div>/**
98 * @cfg {Boolean} draggable
99 * True to allow the window to be dragged by the header bar, false to disable dragging (defaults to true). Note
100 * that by default the window will be centered in the viewport, so if dragging is disabled the window may need
101 * to be positioned programmatically after render (e.g., myWindow.setPosition(100, 100);).
104 <div id="cfg-Ext.Window-closable"></div>/**
105 * @cfg {Boolean} closable
106 * <p>True to display the 'close' tool button and allow the user to close the window, false to
107 * hide the button and disallow closing the window (defaults to true).</p>
108 * <p>By default, when close is requested by either clicking the close button in the header
109 * or pressing ESC when the Window has focus, the {@link #close} method will be called. This
110 * will <i>{@link Ext.Component#destroy destroy}</i> the Window and its content meaning that
111 * it may not be reused.</p>
112 * <p>To make closing a Window <i>hide</i> the Window so that it may be reused, set
113 * {@link #closeAction} to 'hide'.
116 <div id="cfg-Ext.Window-closeAction"></div>/**
117 * @cfg {String} closeAction
118 * <p>The action to take when the close header tool is clicked:
119 * <div class="mdetail-params"><ul>
120 * <li><b><code>'{@link #close}'</code></b> : <b>Default</b><div class="sub-desc">
121 * {@link #close remove} the window from the DOM and {@link Ext.Component#destroy destroy}
122 * it and all descendant Components. The window will <b>not</b> be available to be
123 * redisplayed via the {@link #show} method.
125 * <li><b><code>'{@link #hide}'</code></b> : <div class="sub-desc">
126 * {@link #hide} the window by setting visibility to hidden and applying negative offsets.
127 * The window will be available to be redisplayed via the {@link #show} method.
130 * <p><b>Note:</b> This setting does not affect the {@link #close} method
131 * which will always {@link Ext.Component#destroy destroy} the window. To
132 * programatically <i>hide</i> a window, call {@link #hide}.</p>
134 closeAction : 'close',
135 <div id="cfg-Ext.Window-constrain"></div>/**
136 * @cfg {Boolean} constrain
137 * True to constrain the window within its containing element, false to allow it to fall outside of its
138 * containing element. By default the window will be rendered to document.body. To render and constrain the
139 * window within another element specify {@link #renderTo}.
140 * (defaults to false). Optionally the header only can be constrained using {@link #constrainHeader}.
143 <div id="cfg-Ext.Window-constrainHeader"></div>/**
144 * @cfg {Boolean} constrainHeader
145 * True to constrain the window header within its containing element (allowing the window body to fall outside
146 * of its containing element) or false to allow the header to fall outside its containing element (defaults to
147 * false). Optionally the entire window can be constrained using {@link #constrain}.
149 constrainHeader : false,
150 <div id="cfg-Ext.Window-plain"></div>/**
151 * @cfg {Boolean} plain
152 * True to render the window body with a transparent background so that it will blend into the framing
153 * elements, false to add a lighter background color to visually highlight the body element and separate it
154 * more distinctly from the surrounding frame (defaults to false).
157 <div id="cfg-Ext.Window-minimizable"></div>/**
158 * @cfg {Boolean} minimizable
159 * True to display the 'minimize' tool button and allow the user to minimize the window, false to hide the button
160 * and disallow minimizing the window (defaults to false). Note that this button provides no implementation --
161 * the behavior of minimizing a window is implementation-specific, so the minimize event must be handled and a
162 * custom minimize behavior implemented for this option to be useful.
165 <div id="cfg-Ext.Window-maximizable"></div>/**
166 * @cfg {Boolean} maximizable
167 * True to display the 'maximize' tool button and allow the user to maximize the window, false to hide the button
168 * and disallow maximizing the window (defaults to false). Note that when a window is maximized, the tool button
169 * will automatically change to a 'restore' button with the appropriate behavior already built-in that will
170 * restore the window to its previous size.
173 <div id="cfg-Ext.Window-minHeight"></div>/**
174 * @cfg {Number} minHeight
175 * The minimum height in pixels allowed for this window (defaults to 100). Only applies when resizable = true.
178 <div id="cfg-Ext.Window-minWidth"></div>/**
179 * @cfg {Number} minWidth
180 * The minimum width in pixels allowed for this window (defaults to 200). Only applies when resizable = true.
183 <div id="cfg-Ext.Window-expandOnShow"></div>/**
184 * @cfg {Boolean} expandOnShow
185 * True to always expand the window when it is displayed, false to keep it in its current state (which may be
186 * {@link #collapsed}) when displayed (defaults to true).
190 <div id="cfg-Ext.Window-showAnimDuration"></div>/**
