Question

I created a class CustomCombo.as that extends ComboBox. What is happening is that the CustomCombo combobox is showing as being editable. I do not want this and I cant find the properties to set the editable to false.

I also tried setting the combobox’s textInput.editable control to false, but to no avail.

Any help would be greatly appreciated.

CustomCombo.as

package custom {

    import spark.components.ComboBox;

    public class CustomCombo extends ComboBox {

        public function CustomCombo() {
            super();
//          this.editable = false; //<-- THIS DOESNT WORK   ***Access of possibly undefined property editable through a reference with static type custom:CustomCombo
//          this.textInput.editable = false; //<-- THIS DOESNT WORK   ***Cannot access a property or method of a null object reference
        }
    }
}

After rummaging through the Flex 4 API I found that they suggest to use the DropDownList control. From what I can see is that they removed the editable property from the ComboBox control in Flex 4, but I may be wrong.

I implemented DropDownList and that solved my problem.
