Problem - Add upload file button to an html Editor

[skha]

Hello every one,
As explained in the title, i want to add the possibility to upload images in a directory and add the html code of my image in the text.
I trie this example but the button is not visible.

Ext.onReady(function (){
    Ext.ns('Ext.ux.form.HtmlEditor');

    var w = new Ext.Window({
        width: 860,
        layout: 'fit',
        items: [
                {  
                fieldLabel: 'Description',  
                name: 'description',  
                value: 'bwah bwah',  
                anchor: '100%',  
                id:'monHtmlEditor',
                xtype: "htmleditor",  
                height: 400,  
                listeners:{
                    afterrender:function(){                        
                        this.getToolbar().addItem(
                            [
                                {
                                    xtype: 'form',
                                    id: 'monForm',
                                    url: 'php/webServiceProjet.php?upload=1',
                                    border: false,
                                    fileUpload: true,
                                    items:[
                                        {
                                            xtype: 'fileuploadfield',
                                            id: 'monFileUpload',
                                            name: 'monFileUpload',
                                            buttonOnly: true,
                                            hideLabel: true,
                                            buttonText: '',
                                            tooltip: 'monFileUpload',
                                            buttonCfg: {
                                                iconCls: 'bo'
                                            }
                                            
                                            /*
                                                xtype: 'button',
                                                iconCls: 'bo', //your iconCls here
                                                handler: function(){
                                                    alert('eee');
                                                    //this.cmp.insertAtCursor('<hr>');
                                                },
                                                scope: this,
                                                tooltip: 'horizontal ruler',
                                                overflowText: 'horizontal ruler'
                                            */
                                        }                                        
                                    ]
                                }
                            ]    
                        )
                    }
                } 
            }            
        ]
    });    
    w.show();    
});

i think i can't add a form in my toolbar.

is there a solution to upload images via the htmlEditor?

Thank you in advance for your replies.

You can add your own tool to the editor.

Thank you for your replay.
could you please give me an axample?
i added a button this way:

this.cmp.getToolbar().addButton([{
            iconCls: 'bo', 
            handler: function(){
                this.cmp.insertAtCursor('<img src="./img/test.png');
            },
            scope: this,
            tooltip: 'horizontal ruler',
            overflowText: 'horizontal ruler'
        }]);

I can add an image to my text, but what i want is to display a pop-up to select a document.

thank you again.
