The QuickTips * singleton is used to configure and manage tooltips globally for multiple elements * in a generic manner. To create individual tooltips with maximum customizability, * you should consider either {@link Ext.Tip} or {@link Ext.ToolTip}.</p> * <p>Quicktips can be configured via tag attributes directly in markup, or by * registering quick tips programmatically via the {@link #register} method.</p> * <p>The singleton's instance of {@link Ext.QuickTip} is available via * {@link #getQuickTip}, and supports all the methods, and all the all the * configuration properties of Ext.QuickTip. These settings will apply to all * tooltips shown by the singleton.</p> * <p>Below is the summary of the configuration properties which can be used. * For detailed descriptions see {@link #getQuickTip}</p> * <p><b>QuickTips singleton configs (all are optional)</b></p> * <div class="mdetail-params"><ul><li>dismissDelay</li> * <li>hideDelay</li> * <li>maxWidth</li> * <li>minWidth</li> * <li>showDelay</li> * <li>trackMouse</li></ul></div> * <p><b>Target element configs (optional unless otherwise noted)</b></p> * <div class="mdetail-params"><ul><li>autoHide</li> * <li>cls</li> * <li>dismissDelay (overrides singleton value)</li> * <li>target (required)</li> * <li>text (required)</li> * <li>title</li> * <li>width</li></ul></div> * <p>Here is an example showing how some of these config options could be used:</p> * <pre><code> // Init the singleton. Any tag-based quick tips will start working. Ext.QuickTips.init(); // Apply a set of config properties to the singleton Ext.apply(Ext.QuickTips.getQuickTip(), { maxWidth: 200, minWidth: 100, showDelay: 50, trackMouse: true }); // Manually register a quick tip for a specific element q.register({ target: 'my-div', title: 'My Tooltip', text: 'This tooltip was added in code', width: 100, dismissDelay: 20 }); </code></pre> * <p>To register a quick tip in markup, you simply add one or more of the valid QuickTip attributes prefixed with * the <b>ext:</b> namespace. The HTML element itself is automatically set as the quick tip target. Here is the summary * of supported attributes (optional unless otherwise noted):</p> * <ul><li><b>hide</b>: Specifying "user" is equivalent to setting autoHide = false. Any other value will be the * same as autoHide = true.</li> * <li><b>qclass</b>: A CSS class to be applied to the quick tip (equivalent to the 'cls' target element config).</li> * <li><b>qtip (required)</b>: The quick tip text (equivalent to the 'text' target element config).</li> * <li><b>qtitle</b>: The quick tip title (equivalent to the 'title' target element config).</li> * <li><b>qwidth</b>: The quick tip width (equivalent to the 'width' target element config).</li></ul> * <p>Here is an example of configuring an HTML element to display a tooltip from markup:</p> * <pre><code> // Add a quick tip to an HTML button <input type="button" value="OK" ext:qtitle="OK Button" ext:qwidth="100" ext:qtip="This is a quick tip from markup!"></input> </code></pre> * @singleton */ Ext.QuickTips = function(){ var tip, locks = []; return { /** * Initialize the global QuickTips instance and prepare any quick tips. */ init : function(){ if(!tip){ tip = new Ext.QuickTip({elements:'header,body'}); } }, /** * Enable quick tips globally. */ enable : function(){ if(tip){ locks.pop(); if(locks.length < 1){ tip.enable(); } } }, /** * Disable quick tips globally. */ disable : function(){ if(tip){ tip.disable(); } locks.push(1); }, /** * Returns true if quick tips are enabled, else false. * @return {Boolean} */ isEnabled : function(){ return tip && !tip.disabled; }, /** * Gets the global QuickTips instance. */ getQuickTip : function(){ return tip; }, /** * Configures a new quick tip instance and assigns it to a target element. See * {@link Ext.QuickTip#register} for details. * @param {Object} config The config object */ register : function(){ tip.register.apply(tip, arguments); }, /** * Removes any registered quick tip from the target element and destroys it. * @param {String/HTMLElement/Element} el The element from which the quick tip is to be removed. */ unregister : function(){ tip.unregister.apply(tip, arguments); }, /** * Alias of {@link #register}. * @param {Object} config The config object */ tips :function(){ tip.register.apply(tip, arguments); } } }();
