I am sorry if I state the obvious, but why you don't use a not-simple ComboBox?
The AdvancedComboBox example shows one can use cells in a ComboBox. Although I was confused at first, as I saw a simple text input field, ie. I didn't identify the component as being a kind of combo box. Actually, technically it isn't really a combo box but more like an adaptive search field with a dynamic list below, but I won't argue on this...
A search icon (traditionally a magnifying glass) on the right of the field could help identifying the nature of the component. I wonder if one can easily add such icon.
Hi. Thanks for your reply. Unfortunatelly using a ComboBox with a button will not work for me. The reason is that I need the editors in grid. So I need the buttons to appear when in edit mode.
So, what I need is exactly what I posted: a way to extend ComboBox to be like a twinTriggerField. But I am having troubles to achieve that. With gxt 2, that was quite easy. But I am having troubles to extend the ComboBox on gxt 3.
I would be glad if someone could help me out.
