    Default How to: extend form field to get 2 textbox

    How to: extend form field to get 2 textbox


    hi to all

    at this moment i have a particular need in almost all my forms.

    since 1 image is better then 1000 words i'll attach an image of the desired field.

    for what i understand i need to expand a TriggerField to get the buttons(basically the SearchField Example) but the part to have 2 textfields ( the first to display the client ID, editable;the second to display the client Name, disabled) got me totally lost...

    i had never developed my own fields so yah...i'm lost and i'm noob

    if some one could guide me it would be much appreciate.

    tks

    sorry dude.

    Extend Ext.Container, where the textfield and triggerfield sit side by side(column layout).

    The challenge with doing this is having methods like isValid, markInvalid, clearInvalid, etc.

    i'm having some major (noob) problems with fields communication...

    i created (totally based on other ppl work ) my own xtype that does exactly what i want..

    but now i need them to communicate and thats my problem...

    Code:
    Ext.ux.form.myIdNameField = Ext.extend(Ext.form.TextField, {
    
        initComponent : function(){
            Ext.ux.form.myIdNameField.superclass.initComponent.call(this);
            this.on('keypress', function(f, e){
                if(e.getKey() == 115 && e.button == -1){
                    e.preventDefault();
                    this.append[0].searchHandler();
                }
                if(e.getKey() == 112 && e.button == -1){
                    e.preventDefault();
                    console.debug(this.ownerCt.getForm().findField('firstName').getValue());
                }
            }, this);
        },
        
        append: [{
            xtype: 'myTriggerField',
            width: this.width,
            readOnly:true,
            scope:this,
            cls:'x-item-disabled',
            clearHandler: function(){
                console.debug('clear');
            },
            searchHandler: function(){
                console.debug('search');
            }
        }]
    });
    i need the appended field goes to his "parent" field to get some options like width, height, etc...

    but i don't have a clue how i can do it...the dam scope problems :P

    can anyone give a hand...or two...?
