Hi list,

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)

- 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.

- 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.

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)
