[vwnc] Number of lines shown for drop down of combo box

Is there a way to get more than five lines to show up for the drop-down list of a ComboBox? The painter tool doesn't have the number of lines as a configuration option. I didn't see anything on ComboBoxSpec that looked like I could configure it by editing the windowSpec. I found this comment interesting:

ComboBoxSpec>>getComboListIn: aUIBuilder
...

"To temporarilty deal with the fact that ComboBox drop list were once menus."

...

Whoops, the code I see defines the combolList with a menu. Perhaps more lines would show if I convert to a List or change the menu definition?

It is of course highly intuitive :)

Re: [vwnc] Number of lines shown for drop down of combo box

BTW,

I found that implementing as a menu instead of list was also part of the problem. "self list size" answers 0 for a menu so the size gets set to five (from #emptySize) despite setting maxLines. This is the VW 7.5 code responsible:

ComboBoxButtonView>>dropDownListHeightFor: aDropListView
...

(minSize := self list size) = 0 ifTrue: [minSize := self emptySize].
^gridSize * (self maxLines min: minSize) + 4

Looks like I'll need to use lists instead of menus.

Also, #defaultableComboBoxMaxSize on the look policy is used to configure the number of lines in a general way.
