property ModalResult : TModalResult read FModalResult write FModalResult;
TCustomForm class property. its just variable
on virtualbox system:
I add TButton on form and TButton.ModalResult set to MrOk. and click
to Button then similar work TForm.ModalResult := MrOk.
I don't wanna use tbutton, How to run My code "F.ModalResult := MrOk."
I can reasonably suspect that the code ran from another form will not
have any impact on the form to be closed. In a normal way the form to be
closed responds first to any event (windows local event queue). When the
event code which has been fired finishes with something like
[Self.]ModalResult := mrCancel
the forms manager does its job an does whatever has to be done with the
ModalResult. Most of the time the form is closed when called with
ShowModal. Without ShowModal the form still displays.
So when you execute (in FormMain):
TFormMain.SomeProcedure;
begin
OtherForm.ModalResult := mrOK
end;
nothing happens with OtherForm as no event was running.
If you need the form itself to close follonwing a ShowModal, you have to
create an internal event like the one a timer fires. This is my way to
proceed when I need to manage a timeout on a form but always under the
range of a previous ShoModal.
Hope this hepls to understand.
Antonio.
