The complete toolbar is build in editor/config/config_toolbar.js (when using tb=T010203... parameter then its config_toolbar_auto.js).(in ASP.Net you have to set ToolbarMode = Script)
Just make a copy of an existing button line like
objToolbar1.add(objToolbars.createButton("",imagePath + "my.gif","","myTooltip","MYKEY"));
and add it to the location or toolbar row where the button should appear.
Then add this line to button event handler in function
function onToolbarButtonClick(id){
// add this line // when button is clicked then myFunction is called if(button.tag == "MYKEY") myFunction();
Add a new function like this:function myFunction(){ // open a new window with defined size (centered) var left = screen.width/2 - 400/2; var top = screen.height/2 - 600/2; window.open("my.html","","left=" + left + ",top=" + top + ",height=600,width=400,resizable=1,status=0,scrollbars=1");"}If you are on the opened page you can access any editor API withwindow.opener.editInsertHtml("<b>Hi</b>");This works for both IE and Firefox browsers.For IE only you can also use a modal window:
var ret = window.showModalDialog("my.html",window,"dialogHeight:200px;dialogWidth:400px;resizable:0;status:0;scroll:0");
On the opened page you access the passed "window" parameter like
var editor = dialogArguments;editor.editInsertHtml("<b>Hi</b>");
