'adding a custom icon to a tinyMCE button

I'm trying to add a Font-Awsome icon to a button I added to tinyMCE thus:

 ed.addButton('youtube', {
     title: 'Add Video' ,
     icon: 'icon-youtube',
     onclick: function () {
     //do stuff here...
 }

using an image like the docs suggest was not acceptable but for some reason I am not able to make this work. any ideas?

Solution 1:^[1]

this CSS based solution seems to work nicely:

 i.mce-i-[FONT-AWESOME-CLASSNAME]:before {   // FONT-AWESOME-CLASSNAME e.g. "icon-youtube"
    content: "[FONT-AWESOME-CONTENT]";       // FONT-AWESOME-CONTENT e.g. "\f166"
    font-family: FontAwesome;
    font-style: normal;
    font-weight: normal;
    text-decoration: inherit;
    color: #000;
    font-size: 1.5em;
    padding-right: 0.5em;
    position: absolute;
    top: 15%;
    left: 0;
 }

it is based on matt-royal's answer on this stack exchange wordpress thread

I know this is old, but I thought I would throw in my answer for anyone who is interested. I am using TinyMCE 4. I added this to my CSS

.mce-ico.mce-i-fa {
    display: inline-block;
    font: normal normal normal 14px/1 FontAwesome;
    font-size: inherit;
    text-rendering: auto;
    -webkit-font-smoothing: antialiased;
    -moz-osx-font-smoothing: grayscale;
}

then when I am setting the icon for the buttons I just use.

editor.addButton('adjust', {
    tooltip: 'Adjust Layout',
    icon: 'fa fa-adjust',
    onclick: function () {
        dialogLayout(editor, url, settings);
    }
});

basically this will let you use any font awesome icons without having to have a specific class layout for each icon.

Hope this helps someone.

From what I understand you trying to add a button with an image in the list of icons tinyMCE.

 tinymce.PluginManager.add("youtube", function (editor) {   
    editor.addButton('youtube', {
        tooltip: 'Add video',
        image: tinymce.baseURL + '/plugins/youtube/icons/youtube.gif',
        onclick: function() {

        }
    }); 
});

Create a folder (I named "youtube") in this folder create another folder (I named "icons" in which you put your image), then create your file youtube.js under youtube folder.

For tinymce 5 you can use this sample:

editor.ui.registry.addButton('customButton1', {
    text: '<span class="fa fa-youtube"></span>',
    //icon: '<span class="icon-youtube"></span>',
    onAction: () => alert('Button clicked!')
});

This simple stylesheet worked for me:

i.mce-i-[FONT-AWESOME-CLASSNAME]:before {   // FONT-AWESOME-CLASSNAME e.g. "icon-youtube"
    content: [FONT-AWESOME-CONTENT];         // FONT-AWESOME-CONTENT e.g. "\f166"
    font-family: FontAwesome;
}

It can be used for a toolbar button or menu item equally well.

ed.addButton('youtube', {
     title: 'Add Video' ,
     icon: '[FONT-AWESOME-CLASSNAME]',
     onclick: function () { /* magic */ }
}

ed.addMenuItem('youtube', {
     text: 'Add Video' ,
     icon: '[FONT-AWESOME-CLASSNAME]',
     onclick: function () { /* magic */ },
     context: 'view'
}

Do not use position: absolute because layout in menu will be spoiled.

The following CSS works for TinyMCE 4 and FontAwesome 5:

.mce-ico.mce-i-fas {
    display: inline-block;
    font-family: 'Font Awesome 5 Free';
    font-weight: 900;
    text-rendering: auto;
    -webkit-font-smoothing: antialiased;
    -moz-osx-font-smoothing: grayscale; }

In TinyMCE v5, there's a new tinymce.editor.ui.Registry method called addIcon, that registers a new SVG icon, quoting:

Registers a new SVG icon, the icon name reference can be configured by any TinyMCE 5 Ui components that can display an icon. The icon is only available to the editor instance it was configured for.

Method Parameters:

addIcon(name: String, svgData: String)

name (String) - Unique name identifying the new icon.
svgData (String) - The SVG data string the browser will use to render the SVG icon.

Method Implementation:

// To add a simple triangle icon:
editor.ui.registry.addIcon('triangleUp', '<svg height="24" width="24"><path d="M12 0 L24 24 L0 24 Z" /></svg>');

Then, you can use that unique name identifier in your custom buttons, for example:

editor.ui.registry.addButton('youtube', {
  text: 'Add Video' ,
  icon: 'triangleUp',
  onAction: () => {
    // do stuff here...
  }
});
