Hey guys! New to Silk.NET, wanting to create a transparent window in OpenGL mode. I think the key may be in GLFW but I have no idea how to set my window transparent. I've tried to set 'options.TransparentFramebuffer = true;' but that didn't help. Is there a way to set the window transparent so I can draw a square that 'floats' on top of the desktop? e.g. for notifications and toasts etc ?

Hanprogramer•1/9/23, 1:20 PM

You could in theory get the win32 handle and then manipulate the window from there

are you clearing with

Color.Transparent

Color.Transparent

Color.Transparent

Color.Transparent? that doesn't work (in my experience

Color.Transparent

Color.Transparent

Color.Transparent

Color.Transparent is anything but transparent), you'll have to manually set the alpha value to 0
otherwise as long as you enable transparent framebuffer it should work fine.

Hi @grifon.petre - in my OnWindowLoad() I am doing Gl.ClearColor(1.0f, 1.0f, 1.0f, 0.5f); and then in OnWindowRender I am doing Gl.Clear(ClearBufferMask.ColorBufferBit);

In Arrays of Objects the objects are not guaranteed to be stored Contiguously. In Arrays of Structs the structs are, meaning it's more likely the CPU has the data already sitting in cache therefore doesn't need to go and fetch it for memory

after my complete and utter brainfart the other day i had a think about how to fix it in a way that worked well for the user but also meant there was no risk of the runtime moving the pointers around and i finally managed to fix it
so there are now pointer overloads (which it uses internally) and the safe overloads as well yay

So what I want to appear is the square, but not the black background, that needs to be transparent, and I should be able to click through it - it should 'float' like a toast message "You have one new viewer" or something like it.

YESSSSS that works - it's transparent!! Now, how do I enable Click-Through?

A

Aqua•1/10/23, 1:42 AM

I don't believe click through is possible with glfw, potentially SDL, but you'll probably have best luck with using win32/x11/whatever directly (is click through even possible though??)
either way this is not something the silk window handles itself

D

Deleted User•1/10/23, 1:43 AM

Click-through is possible with glfw, lemme get the code that 'should' do it (if I could directly access the glfw component that is)

Aqua•1/10/23, 1:49 AM

this seems like it is a new feature in 3.4, but silk uses 3.3 currently (I don't believe 3.4 has even been fully released yet)
so once 3.4 releases silk will be updated to include this too.
can't say for certain whether or not the silk windowing will be updated to feature this, but it wouldn't take much to implement it, and if you wanted to you could submit a PR to have this added too.
for now though I don't think there's much that can be done

A

Aqua•1/10/23, 1:51 AM

if you really wanted to you could manually replace the glfw files with ones for 3.4 and then find the integer value of

MOUSE_PASSTHROUGH

MOUSE_PASSTHROUGH

MOUSE_PASSTHROUGH

MOUSE_PASSTHROUGH and sorta force it into the window hint, but I wouldn't recommend doing that at all

D

Deleted User•1/10/23, 1:51 AM

Ok that's unfortunate. So you mention SDL may be able to do it - is there an example/tutorial that draws a simple square in SDL where I can get this click-through, transparent window enabled? Just starting out with Silk.NET and really want to get this working. I'm trying to 'fail fast' based on the features I need, but I'd really like to 'succeed' as well

A

Aqua•1/10/23, 1:51 AM

plus you'd have to write a custom glfw window I believe

D

Deleted User•1/10/23, 1:52 AM

Ye that was what I was trying to do, but wasn't sure - the documentation/tutorials are few and far between. But happy to test using SDL

A

Aqua•1/10/23, 1:57 AM

in theory you could do

glfw.WindowHint((WindowHintBool) IntValueOfMousePassthrough, true);

glfw.WindowHint((WindowHintBool) IntValueOfMousePassthrough, true);

glfw.WindowHint((WindowHintBool) IntValueOfMousePassthrough, true);

glfw.WindowHint((WindowHintBool) IntValueOfMousePassthrough, true);

Deleted User•1/10/23, 1:57 AM

I guess where I'm stuck is how do I 'inject' anything glfw into 'IWindow' object?

A

Aqua•1/10/23, 1:58 AM

at that point you'd have to write your own windowing system though, I don't believe silk initializes glfw until you call

window.create

window.create

window.create

window.create, and I don't believe there's any way to give it your own window hints either

D

Deleted User•1/10/23, 1:59 AM

Ah that's what I was afraid of

A

Aqua•1/10/23, 2:00 AM

aha, perfect
you can set it with ,

glfwSetWindowAttrib

glfwSetWindowAttrib

glfwSetWindowAttrib

glfwSetWindowAttrib during runtime, so that's one problem solved.
now it's just about getting the glfw handle itself from the window, which I have a suspicion is something you can actually do without resorting to reflection - but I'd have to check

DDeleted User Ah that's what I was afraid of 😦

A

Aqua•1/10/23, 2:08 AM

hmm, seemingly not but I'm not at a machine to test it out at the moment - however you can use reflection to get the internal

Glfw

Glfw

Glfw

Glfw object stored in the

GlfwWindow

GlfwWindow

GlfwWindow

GlfwWindow
and if you can get that working then I wish you the best of luck because there's no guarantees that it will be happy with the fact that you've swapped 3.3 dlls with 3.4 (for example function signature changes could cause a lot of problems)
so don't expect this to work

D

Deleted User•1/10/23, 2:08 AM

The demo code below will allow me to setup the window borderless and transparent etc. And I'd be able to add the clickthrough if using 3.4 and setting that window hint, so that would all work. Now I'm wondering, how could I use that created window and somehow get all the goodness from Silk.NET like event handlers etc
