Currently, Items.Objects[] is used as a pointer:
{ TCheckComboItemState }
TCheckComboItemState = record
State: TCheckBoxState;
Enabled: Boolean;
end;
PTCheckComboItemState = ^TCheckComboItemState;
I needed to hook there because the combo can be sorted and Objects are sorted
too.
If it is enough, I can extend the record to:
{ TCheckComboItemState }
TCheckComboItemState = record
State: TCheckBoxState;
Enabled: Boolean;
Data: TObject;
end;
PTCheckComboItemState = ^TCheckComboItemState;
which will allow to users to have associated object but working with Data will
be little different
than working with normal Combo.
Instead
Items.Objects[i];
it will be
PTCheckComboItemState(Items.Objects[i])^.Data;
Although, I can do new property TCheckComboBox.Objects[] and getters + setter
will do the job.

The second is combo with checkboxes. Internally it uses Items.Objects[] for
storing State and ItemEnabled.
Can you change that?
Items.Objects is usually for users custom data.
