Hi all,

it would be nice if you could close/cancel a dialog by pressing the back button on your smartphone. Is there any event, handler etc. to make it happen?

Yes that works using TAddress and its anchor property: have a look here to get the basic information:

Uli,

thanks for the hint. I checked the discussion before asking  but I don't see how that can be used in a dialog or form made visible with .ShowModal. Maybe it might work if I handle Application.OnAnchor in every modal form (simply calling Close there), set .Anchor in these form, and set it again after the modal form closed. But I must admit that this is a little bit more work than I an willing to invest

Up to you - for me it's not a big deal:

I assign the Address.Anchor property in the OnShow event of each form:

   Address.Anchor := Self.Name;

In the OnAnchorChange event handler it looks like this:

....
else if SameText(Address.Anchor,'AdminForm') then
   begin
      if Assigned(NewsEditForm) then
         NewsEditForm.Close;
      AdminForm.Show;
   end else if SameText(Address.Anchor,'NewsEditForm') then
   begin
      if Assigned(HTMLEditForm) then
         HTMLEditForm.Close;
   end else if SameText(Address.Anchor,'') then
....

Uli,

I tested it, and it works great. In full screen you don't even see the more or less ugly bookmarks
