Combobox: hot to move the selection while typing ?

All,
I would like to know if a Bmax combobox can behave like a VB combobox, that is, typing a string when the combolist is displayed, should move the selected item accordingly.

Suppose you have a sorted combobox with a list like:
Apple
Avocado
Banana
Mango
Marmelade
Peech
Water melon

You want to select, for example, Marmelade.

Clicking on the combo down arrow button, you will presented with the full list; typing with your keyboard the letter M, the list should automatically locate and select the first item starting with M (in this case, Mango).
While you type, M A R it should now locate and select Marmelade.

Is it possible with the Bmax GUI ? Or should I create a user combobox, with some automation inside ?

Thanks for your attention,
Sergio.

This is usually a custom control in most languages. Except in VB :)

Edit: Then again. Calling VB an actual language, might be a stretch ;)

Except:+ .NET

and VB.NET is used more and more for regular applications.

Ok, but how to replicate this behaviour with a BMax Combobox control ?

Only by creating an own combobox gadget. the actual one does not allow usage of the textfield and the dropdown list at the same time.

Thanks.

Do you know how to create an own gadget then ?

Is it possible to extend the main gadget, like

type mycombo extends ComboBox

?

Or you mean that the mods should be modified and then re-compiled ?

You must modify the module with C / C++ code and add the needed "hooking" in BM code to get it working.

Extending TGadget within BM does not work (nor does extending TWin32Gadget and others)

Okee-Dokee.

It's not a trivial task then...
