    Exclamation Answered: Disable / Enable a trigger in triggerfield

    Answered: Disable / Enable a trigger in triggerfield


    I have a trigger field as follows:

    Code:
    xtype: 'triggerfield',
    emptyText: 'click the trigger',
    trigger1Cls:'x-form-search-trigger',
    trigger2Cls:'x-form-view-trigger',
    allowBlank: false,
    onTrigger1Click : function() {
    	// action for search
    },
    onTrigger2Click : function() {
    	// action for dropdown
    }
    Now, in my form I have a condition where-in I need to disable the search trigger (trigger1Cls).. how do I disable the specific trigger alone and later enable it?

  2. Relative to a combo:

    var c = new Ext.form.field.ComboBox({
    renderTo : Ext.getBody(),
    store : ['blah','blah blah']
    });
    c.triggerEl.elements[0].addCls('x-item-disabled')

    That would just apply the CSS. Users will be able to still click and invoke the action method. I am looking for disabling the listener methods as well.
    Since, I didn't get any one shot solution, I am currently handling the functionality as:
    1. Add / Remove the "x-item-disabled" CSS class.
    2. Handle the execution of code at listener methods by look at the trigger's state.

    Any other way to handle this situation?
    Thanks and Regards,
    Abdel Olakara.

    You could do

    Code:
    this.triggerEl.elements[0].mask();
    and on click check if it is masked with

    Code:
    this.triggerEl.elements[0].isMasked();
