Other B4XComboBox - strange "behavior" about its width.

[LucaMs]

I'm investigating , also because I'm developing (completing) a my custom version (see this) on this strange thing:

(found also problems about item background colors, good with b4j, bad with b4a, I don't know with b4i)

B4J - it is a bug in ComboBox.

P.S. ... or it prefers the Led Zeppelin

I fear that I have to change a lot, using a xCLV as base (and Erel too, in his B4XComboBox). What do you think?

 

[Erel]

This is the native ComboBox behavior. It probably depends on the maximum width of items that are considered in the visible range.

B4XComboBox is a thin wrapper above the native "combo box". I don't see it changing.

 

[LucaMs]

I don't see it changing.

What does it mean? "I don't see the reason to change it"?

 

[Erel]

It means that it will not be changed.

By chance (pure guess) could it be that one of the items has a bunch of spaces at the end? Are you Trim(ming) the values before adding them to the combo box? Have you used Length to see what the longest length item is that is added to the combo box? Just noting some things that could be investigated...

No, I have not checked, the data come from an example db found on internet, but I think there are no spaces at the end. If I haven't already thrown it all away , I can check it anyway.

On the other hand, the purpose of my version, a modification of Erel's B4XComboBox, is for the classic list of texts of a field and their IDs; it would be sufficient to truncate the texts, all with a maximum length, since the important data to be obtained is precisely the ID.

lstTexts.Add(Cursor.GetString(DisplayFieldName).Trim)
Added ".Trim" - same behaviour.

Added a max length for the display text to my SetItemsFromSQLite method - passed 15, here (and my B4XTblClmUtils, just to test it too):

The important thing, as you know, is that I get the ID from the select item:
log:
Led Zeppelin
ID = 22
