[Qt] QT binding anomalies

[Juha Manninen]

I found one minor thing from the code when debugging.

procedure TQtComboBox.setEditable(const AValue: Boolean);
begin
  QComboBox_setEditable(QComboBoxH(Widget), AValue);
  if not AValue then
    FreeAndNil(FLineEdit)
  else
  begin
    LineEdit.setFocusPolicy(getFocusPolicy);
    setText(FText);
  end;
//  if AValue then
//    setText(FText);
end;

The last commented lines can be removed.

I didn't find the actual problem I was looking for. I noticed however that the 
problem happens AFTER assigning stringlist to combobox items, not during the 
assignment.
There is a complicated set of messages as you suggested and they are very 
difficult to debug.

I don't know how to disable them and now my brain capacity is used for today. 
I may return to this later but I may also wait until you have new versions of 
everything and you experience this problem, too. :-)

I even set breakpoints to 
  TQtLineEdit.getText and TQtLineEdit.setText
but they were not triggered. I don't know what is happening there, it may not 
be the edit control after all.
