Hi Lazarus team,
I've two issues with a ComboBox (csDropDown) control in Windows:
1. ComboBox.AutoSelect:=false isn't working. I seems that Windows always
selects the whole ComboBox.Text at activation of the control.
2. Changing the ComboBox.Font (.Style, .Size or .Color) overwrites the
ComboBox.Text with the first matching item of ComboBox.Items.
ComboBox.Style is csDropDown. Look at this code:
procedure TForm1.SpeedButtonTestClick (Sender: TObject);
begin
ComboBox1.Clear;
ComboBox1.Items.Add('Item0');
ComboBox1.Items.Add('TestItem1');
ComboBox1.Items.Add('Item2');
ComboBox1.Text:='Test';
if fsBold in ComboBox1.Font.Style then
ComboBox1.Font.Style:=ComboBox1.Font.Style-[fsBold]
else
ComboBox1.Font.Style:=ComboBox1.Font.Style+[fsBold];
end;
ComboBox1.Text is set to 'TestItem1'.
I'd a good look into customcombobox.inc and win32wsstdctrls.pp (Windows
10 x64, Lazarus 1.9 57316) trying to analyse this without any idea.
Meanwhile I think that both issues are MS Windows ones. But I don't have
a Linux environment to check it. Maybe someone else can do?
Is there any interest in a patch to solve MS Windows issues although the
patch would add some windows specific code to stdctrls.pp and
customcombobox.inc? I've a solution for the "AutoSelect=false" one and
an idea for the second one.
Rolf
