In Delphi 6, I could change the Mouse Cursor for all forms using Screen.Cursor:
procedure TForm1.Button1Click(Sender: TObject);
begin
Screen.Cursor := crHourglass;
end;
I am searching the equivalent in Firemonkey.
Following function does not work:
procedure SetCursor(ACursor: TCursor);
var
CS: IFMXCursorService;
begin
if TPlatformServices.Current.SupportsPlatformService(IFMXCursorService) then
begin
CS := TPlatformServices.Current.GetPlatformService(IFMXCursorService) as IFMXCursorService;
end;
if Assigned(CS) then
begin
CS.SetCursor(ACursor);
end;
end;
When I insert a Sleep(2000); at the end of the procedure, I can see the cursor for 2 seconds. But the Interface probably gets freed and therefore, the cursor gets automatically resetted at the end of the procedure. I also tried to define CS as a global variable, and add CS._AddRef at the end of the procedure to prevent the Interface to be freed. But it did not help either.
Following code does work, but will only work for the main form:
procedure TForm1.Button1Click(Sender: TObject);
begin
Application.MainForm.Cursor := crHourGlass;
end;
Since I want to change the cursor for all forms, I would need to iterate through all forms, but then the rollback to the previous cursors is tricky, as I need to know the previous cursor for every form.
My intention:
procedure TForm1.Button1Click(Sender: TObject);
var
prevCursor: TCursor;
begin
prevCursor := GetCursor;
SetCursor(crHourglass); // for all forms
try
Work;
finally
SetCursor(prevCursor);
end;
end;
