ShowModal is not working anymore?
« on: April 12, 2016, 10:28:27 pm »
Hi,

I am not quite sure, but I cannot display a form as modal in WinCE platform. For example, attached program becomes unresponsive (picture 2) after clicking "Modal Show Form2" button (picture 1).

Project has 2 forms total. Only Form1 is auto created. When button clicks, Form2 created and displayed with ShowModal. Unfortunately, code executes it, directly goes to Free section and application become unresponsive.

If I change code to Form2.Show; everything is just fine.

My device is from http://www.dsic.co.kr/ model is DS5 under mobile solutions.

Thanks & regards,
-Ertan

Probably it's a bug! Unfortunately I don't have WinCE to test it.

As a  quick workaround(asically you achieve the same thing):
1. Unit1
Code: Pascal  [Select][+][-]
  1. uses unit2;
  2.  
  3. procedure TForm1.Button1Click(Sender: TObject);
  4. begin
  5.   Form1.Enabled := False;
  6.   Form2 := TForm2.Create(Self);
  7.   Form2.Show;
  8. end;

2. Unit2
Set Form2 FormStyle to fsStayOnTop/fsSystemStayOnTop
Code: Pascal  [Select][+][-]
  1. uses unit1;
  2.  
  3. procedure TForm2.FormClose(Sender: TObject; var CloseAction: TCloseAction);
  4. begin
  5.   CloseAction := caFree;
  6.   Form1.Enabled := True;
  7. end;

Hi,

Yes, similar thing can be achieved with your sample code. I used to use Modal windows myself. Show one get information from it. Continue with received information kind of coding what I generally do.

This will somehow change my habits, leading me to a bug full of coding  %)

You can always fill a bug report: http://bugs.freepascal.org/view_all_bug_page.php?project_id=1 . Hopefully somebody will fix the issue.

My test with Lazarus 1.7, fpc 3.0.0, SVN revision 52294 is a success.
ShowModal is working as it should be with above version.

Just wanted to follow up.
