    Default combobox with renderer and custom syles when expanded

    Hallo!
    I thought, that it would be fine, if you have a renderer in the combobox, since the tpl is kinda handicapped.
    If you want you can override it, if you want to have an extension, you can use another registration than "combo"

    Code:
    Ext.ux.ComboBox2 = Ext.extend(Ext.form.ComboBox, {        //  constructor function
            constructor : function (config) {
                if (config.renderer) {
                    //tpl Łberschreiben
                    //if(config.tpl){console.warn("TPL von Combo "+(config.dbid?config.dbid:' ')+" wird Łberschrieben!");}
                    config.tpl = '<tpl for=\".\"><div ext:qtip="{' + config.displayField + '}" class="x-combo-list-item"> {__styleField} </div></tpl>';
                    config.store.on("load", function () {
                        config.store.each(function (rec) {
                            var o = config.renderer(rec); //o.style kann und o.value muss vorhanden sein
                            if (!o.value) {
                                o.value = rec.get(config.displayField);
                            }
                            if (!o.style) {
                                o.style = "";
                            }
                            rec.set("__styleField", '<span style="' + o.style + '">' + o.value + '</span>');
                        });
                    });
                }
                Ext.ux.ComboBox2.superclass.constructor.apply(this, arguments);
            }
        });
    //Registrierung auf das bestehende ext combo Element, forgive me this sin
    Ext.reg("combo",Ext.ux.ComboBox2);
    How to use:
    Code:
    {    xtype:"combo",
        renderer : function (rec) {
            var o = {};
            o.value = rec.get("bez");
            if (rec.get("rf") == 0) {
                o.style = "color:red;";
                o.value = rec.get("v");
            }
            if (rec.get("rf") == 4) {
                o.style = "color:green;";
                o.value = rec.get("altV");
            }
            return o;
        },
        ...
    }

    Default

    How is the tpl handicapped? I find XTemplate very powerful and flexible.

    Default

    Hi,
    I didn't find a way to do the thing in the code example like
    if 0 then color red, if 4 then color green.
    Its also difficult to read.
