Hi all
It will be different from the following codes.
How can I hide the mouse as it applies to all programs on the desktop.
Code: Pascal
[Select]
[+]
[-]
procedure
TForm1
.
FormMouseEnter
(
Sender
:
TObject
)
;
begin
ShowCursor
(
False
)
;
end
;
procedure
TForm1
.
FormMouseLeave
(
Sender
:
TObject
)
;
begin
ShowCursor
(
True
)
;
end
;
and
Code: Pascal
[Select]
[+]
[-]
Form1
.
Cursor
:
=
crNone
;
// or Screen.Cursor:=crNone;

Hello,
This is generally considered to be a poor design choice. If you still wish to do it it is likely you will need to create a way to do it for each platform you are interested in. Under Windows, for
example
(from
here
). As you might be able to glean from that solution it's a nonstandard thing to do and each Window expects to be able to set its own cursor style.

That's a "poor design choice" for desktop applications, but if you are using SDL/GLFW/whatever, then you can do this in a cross platform, consistent way.
Haven't done this (yet) with Lazarus/FPC, but there are several LCL/FPC game libraries around.

Object Pascal programmers should get rid of their "component fetish" especially with the non-visuals.

The easiest way would probably be to build your own fully transparent cursor and load that one.
Like the attached one...
EDIT: exactly like the mouse in the picture...
EDIT2: But I would suggest to use ClipCursor or something like that, because a transparent cursor is still active, so the user can click on whatever...
