ExtJS 4 or 4.1 MessageBox Custom Buttons

Question

Ext.MessageBox.show({
    title:'Messagebox Title',
    msg: 'Are you sure want to delete?',
    buttons: {yes: "Some Button 1",no: "Some Button 2",cancel: "Some Button 3"}
});

ExtJS 4 or 4.1 does not support this code. Buttons do not show.

Answer 1

Just found out how to do this, hopefully it helps someone. As you can see you can handle the buttons however you want. Note that the framework only has 4 buttons by default and that is a limitation that won't be easily overcome. In the source there are multiple loops hard coded from 0 to < 4.

Ext.MessageBox.show({
    title:'Messagebox Title',
    msg: 'Are you sure want to delete?',
    buttonText: {yes: "Some Button 1",no: "Some Button 2",cancel: "Some Button 3"},
    fn: function(btn){
        console.debug('you clicked: ',btn); //you clicked:  yes
    }
});
