Both mails were very helpful:
I tried these features on windows 11 and couldn't find a solution
for them in Gem. So I wanted to check if there is something I
missed, or they can be done using other methods. Is it possible to
do any of the following things on a gemwindow?
- remove the window borders/menu or make them black
you can create a Gem window with or without the border, sending a
[border 0/1< message to gemwin before the creation.
the trick here is to send the message *before* creating the Gem window.
(to make things a bit more confusing, there *are* some Gem window
backends that allow to enable/disable the border after the window has
been created; but most do not, and most importantly the default
backend (glfw3) does *not* support it, so it's better to assume that
you have to send the message before creation)
strangely I was sure that I had done it like that, including when
playing with the help patch. but it works now.
- move the window using the patch, not the mouse
Without border, you can create the window wherever you want (but not
move it), with the offset message.
hmm, well.
with the default windowing backend (glfw3), you *can* send an "offset"
message after creating the Gem window and move the window around
(regardless of whether the window was created with or without borders).
other backends may differ.
It does work here. I think I didn't notice this being documented.
- make a window fullscreen on screen 2 - it seems to work on screen
1, but not on 2
on some OS, fullscreen 2 works.
again, this is a matter of windowing backend more than of OS.
but indeed, it might work on your system - or not. and [gemwin] might
agree about what the 2nd screen actually is - or not.
This doesn't seem to work, but when the borders are off and the
background is black, it looks like a fullscreen anyway.
If not, you can adapt and use this message to gemwin :
[reset, offset 1920 0, dimen 1920 1080, border 0, create, 1<
this should always work (but apparently you need to know layout of
your screens beforehand)
Yes, my message was already similar to that. Very good, things seem to
be working.
The purpose is to project an image over a poster, and the shapes
(rectangles) must match the music systems in the poster as well. I
already noticed that it's quite impossible to do this only by moving the
projector, so I added commands in the patch to move the gem window and
it's contents on all 3 axes, makes it much easier to set. I was thinking
also of adding the possibility of making a trapeze function for each
corner: any suggestion on which object to use? Any other real-life
suggestion on how to make the projection easier?
Best,
Joao
