Can’t enter Memo by clicking the mouse

Question

Can’t enter Memo by clicking the mouse

In my project I have a TMemo and a TDBMemo, all of them have implemented an input and output event of the component, from a while to here began that error of not being able to enter the memo by clicking with the mouse. I do not know what is wrong because everything worked well. I will leave the Form code to analyze.

This is the Form I can’t enter with the mouse click Remembering that, Memos are not disabled and not read-only.

The one below is what I call the form

  if frmManutencaoProcessos = Nil then
  begin
    frmManutencaoProcessos        := TfrmManutencaoProcessos.Create(self);
    frmManutencaoProcessos.Parent := frmTelaPrincipal;
  end;
  frmAndamentoProcessual.Show;

I changed the shape and Create Form I don’t know if you have any different things with respect to creation, but it’s still not working as it should when I create the form from the above mode.

Image of the Object Inspector TMemo

If you need any more information just ask me to post it.

I don’t understand Forcaentradaclick. At first it’s not necessary. Are you assigned to some event Handler? The Tabstop property of Memo is true?

Forcaentradaclick is a gambiarra created to enter the memo by right-clicking. because it is not entering normally.

has investigated the functioning of this routine? frmTelaPrincipal.MudaCorEntrada(Sender);

The Routine frmTelaPrincipal.MudaCorEntrada(Sender); is working properly for all fields where the routine is applied.

After the SetFocus, use PostMessage(TMemo(Sender).Handle, WM_SETFOCUS, 0, 0);

The image component name is dbmDescricao_PublicacaoIncl, but I didn’t find this reference in the code. Post as is the tab Events of TMemo specific. I noticed that in procedure TfrmAndamentoProcessual.FormShow(Sender: TObject); is manipulating the Focus dbgPesquisaAndamentos.SetFocus; if you have any Tmemo event set to FormShow then that may be the problem, for example if OnClick of TMemo is FormShow, then every time you click on Memo who will receive the focus will be the dbgPesquisaAndamentos.

It’s because I reset the Component’s name to dbm_Observacao because it’s too big.
