Hi,
On Windows a DBLookupComboBox not show any value before explicitly set
KeyValue to not null value or select value at runtime. This is correct.
On Kubuntu 14.04 64bit+Qt, if open the DataSet(query) or add a record to
an empty DataSet in FormShow the first record showed in
DBLookupComboBox, see the example below. But if do open/append in
FormCreate works like with Windows, no value selected automatically. Why
a value selected automatically if call open/append in FormShow? I use
fixes_1_4(49527) with fixes_3_0(31206).
procedure TForm1.FormCreate(Sender: TObject);
begin
BDS:=TBufDataset.Create(Self);
BDS.FieldDefs.Add('ID',ftInteger);
BDS.FieldDefs.Add('NAME',ftString,10);
dsBDS:=TDataSource.Create(Self);
dsBDS.DataSet:=BDS;
DBLookupComboBox1.Style:=csDropDownList;
DBLookupComboBox1.ListSource:=dsBDS;
DBLookupComboBox1.ListField:='NAME';
DBLookupComboBox1.KeyField:='ID';
BDS.CreateDataset;
end;
procedure TForm1.FormShow(Sender: TObject);
begin
BDS.AppendRecord([1,'aaa']);
end;
