Allow enter to select items from combobox's list.

[basicer]

Currently if you use the keyboard to search though a combobox and try to select an item with enter, it will close the form without sending the update.

Do you know of a mod which allows me to test it?

[basicer]

minetest.register_chatcommand("z", {
	func = function(name, param)
		minetest.show_formspec(name, "z", "size[5,1]\ndropdown[0,0;5;test;A,B,C,D,E,F,G,H,I,J,K,L,M,N,O,P;1]")
	end,
})

minetest.register_on_player_receive_fields(function(p, formname, fields)
	if formname == "z" then minetest.chat_send_all(fields.test or 'nil') end
end)

With the patch you can click the combo-box and enter a letter on the keyboard then press enter to select. The correct letter will show in chat.

Without the patch, doing the above will close the form and previously selected letter will remain.

Thanks.

Indentation looks weird, please remove any spaces.

[SmallJoker]

It's logical, as it's within the parentheses.

[paramat]

I know it's done to line stuff up, but we have a strict rule to never use spaces in indentation.

LGTM

	// Fix Esc/Return key being eaten by checkboxen and tables
	if(event.EventType==EET_KEY_INPUT_EVENT) {
		KeyPress kp(event.KeyInput);
		if (kp == EscapeKey || kp == CancelKey
				|| kp == getKeySetting("keymap_inventory")
				|| event.KeyInput.Key==KEY_RETURN) {

Only RETURN should select, Escape / Cancel / Inventory keys should continue to close the form.

No response to requests for a month, closing for now.
