you have to add this code to your show function

If WindowState = wsMinimized then WindowState := wsNormal;

it should work …

Stanleyxu,

I could reproduce this behavior with the Console as well. I do not think it’s a critical issue, though. After all, if your application is minimized, you can easily restore it with the task bar. Or have I missed anything? We use the tray icon mainly for “closing” the Console to the tray bar and restore works fine in this case.

Hi Tobias, I have not submitted the issue to QC yet.

BTW: There must be some tricky code to make it work properly. But I am too lazy to try. I think, that to make everything compiled with D2009 is just the first step of the migration. Without enough tests, we can grantee nothing. I hate migration but I like UnicodeString. Difficult to decide ^^)

Stanleyxu,

will take a look, thanks for the details. Has you already added a bug report for this?

Lachlan,

sorry, no Turbopower components. I ported several smaller components (combo boxes, group boxes, help system related, among others) and the MP hex editor.

If your 3rd party component toolbox is too “big”, then it has always been tricky to upgrade from one Delphi version to the next. I doubt that Unicode is the real reason if some components are still not ported.

Just curious which third party components you had to port to D2009. Anything by Turbopower by any chance?

You add TTrayIcon and TApplicationEvents on your main form.

procedure TForm1.AppliationEvents1Minimize(Sender: TObject);
begin
self.Hide;
end;

Add a popup menu on form, create an item “Restore”, and assign it to TrayIcon.

procedure TForm1.Restore1Click(Sender: TObject);
begin
Self.Show;
Application.BringToFront;
end;

I minimize my application and then try to restore it by right clicking tray icon and selecting “Restore”.
But I cannot bring my main form back to front. Do you have any idea?

There are several test cases to be tested:
1. Click the minimize button (the “_” button ) from right-top-edge.
2. Select “Minimize” from system menu
3. Click “Show desktop” button on taskbar.

If I turn off MainFormOnTaskbar, it does not have any problem to bring the main form back.

Olaf,

I think that would have been a great idea (and probably still is). A central place where people could lookup the state of Delphi 2009 support of specific components and libraries with the option to download a diff would be very useful for companies deciding/struggling with updating to Delphi 2009.

We are also using the MainFormOnTaskBar option and TTrayIcon. I haven’t seen any problems with this combination so far. Could you be a bit more specific? Thanks!
