/**
|
||
|
* Adds HTML/CSS stylable tooltips to HTMLElements.
|
||
|
*
|
||
|
* You can find these tooltips throughout Cloud9. For instance the
|
||
|
* {@link findreplace} and {@link findinfiles} plugins use it to display
|
||
|
* help messages when hovering over the options buttons. The
|
||
|
* {@link autosave} plugin uses a tooltip to
|
||
|
* explain to the user why the save button no longer works.
|
||
|
*
|
||
|
* This example shows how to add a tooltip to a div that shows
|
||
|
* after 1 second:
|
||
|
*
|
||
|
* tooltip.add(someDiv, {
|
||
|
* width : "100px",
|
||
|
* timeout : 1000,
|
||
|
* hideonclick : true,
|
||
|
* message : "Use <span style='color:red'>HTML</span> in "
|
||
|
* + "this message."
|
||
|
* });
|
||
|
*
|
||
|
* This example shows how to add your own HTMLElement as a tooltip to
|
||
|
* another div that is shown immediately when a user hovers over it. The
|
||
|
* placement of the tooltip is calculated in the getPosition method.
|
||
|
*
|
||
|
* tooltip.add(someDiv, {
|
||
|
* message : "Some Message",
|
||
|
* width : "auto",
|
||
|
* timeout : 0,
|
||
|
* tooltip : myTooltipDiv,
|
||
|
* animate : false,
|
||
|
* getPosition : function(){
|
||
|
* var left = 100;
|
||
|
* var top = 100;
|
||
|
* return [left, top];
|
||
|
* }

* });
