<h2>Creating your own plugins</h2>
|
|
<p>
|
|
Creating you own plugins for the TinyMCE application is fairly easy if you know the basics of HTML, CSS and Javascript. The most easy way is to copy the "_template" directory or one of the other core plugins and work from there. The "_template" directory is a tutorial plugin that shows how to create a plugin. After you copy the template you need to change the red sections marked below to the name of your plugin this is needed so that plugins don't overlap in other words it gives the plugin a unique name. Then just alter the source code as you see fit remember that your custom plugins needs to be located in tiny_mce's "plugins" directory. If you want you may add plugin specific options/settings but remember to namespace them in the following format "<your plugin>_<option>" for example "yourplugin_someoption".

The example below has three functions, these are explained in greater detail below.
|

</p>
|
|
<p>
|
|
<div class="example">
|
|
<pre>
|
|
function TinyMCE_<span class="marked">yourplugin</span>_initInstance(inst) {
|
|
// Gets executed when a editor instance is initialized
|
|
}
|
|
|
|
function TinyMCE_<span class="marked">yourplugin</span>_getControlHTML(control_name) {
|
|
// Gets executed when a button is to be generated
|
|
}
|
|
|
|
function TinyMCE_<span class="marked">yourplugin</span>_handleNodeChange(editor_id, node, undo_index, undo_levels, visual_aid, any_selection) {
|
|
// Gets executed when the selection changes
|
|
}
|
|
|
|
function TinyMCE_<span class="marked">yourplugin</span>_execCommand(editor_id, element, command, user_interface, value) {
|
|
// Add your own custom commands here
|
|
|
|
return false;
|
|
}
|
|
|
|
function TinyMCE_<span class="marked">yourplugin</span>_cleanup(type, content) {
|
|
// Add your own custom cleanup here
|
|
|
|
return content;
|

}

<h3>Creating popup HTML files</h3>
|
|
<p>
|
|
When creating a popup you need to include the "tiny_mce_popup.js" this enables you to retrive the tinyMCE global instance in all popup windows. All variables and language definitions gets replaced in the page when it loads. So language variables such as {$lang_something} can be places in the HTML code, if you need to get a language string in JavaScript simply use the tinyMCE.getLang function.
|
|
</p>
|
|
<h3>Example of simple popup file:</h3>
|
|
<div class="example">
|
|
<pre>
|
|
<html>
|
|
<head>
|
|
<title>{$lang_plugin_sample_title}</title>
|
|
<script language="javascript" src="../../tiny_mce_popup.js"></script>
|
|
<script language="javascript">
|
|
// getWindowArg returns any arguments passed to the window
|
|
alert(tinyMCE.getWindowArg('some_arg'));
|
|
</script>
|
|
<body>
|
|
<strong>{$lang_plugin_sample_desc}</strong>
|
