Code:
EditorUi.prototype.createHoverIcons=function(){return new HoverIcons(this.editor.graph)};EditorUi.prototype.redo=function(){try{this.editor.graph.isEditing()?document.execCommand("redo",!1,null):this.editor.undoManager.redo()}catch(a){}};EditorUi.prototype.undo=function(){try{var a=this.editor.graph;if(a.isEditing()){var c=a.cellEditor.textarea.innerHTML;document.execCommand("undo",!1,null);c==a.cellEditor.textarea.innerHTML&&(a.stopEditing(!0),this.editor.undoManager.undo())}else this.editor.undoManager.undo()}catch(f){}};
