Answered 2022-Mar-30 at 17:45

I'm not familiar with ImGui, so I don't know what functions might or might not need to be called in ImGui.

But, GLFW is a relatively low level windowing API that has no regard for the higher level abstractions that might exist on the window. When you pass the callback to glfwSetCursorPosCallback, that callback will be called on any accessible part of the window.

If you need to have the mouse movements (or any mouse interactions) only respond when the mouse is hovered over the relevant part of the interface, you need some kind of mechanism to define what that part is. Again: I don't know how you'd do that in ImGui, but it'll probably look something like this:

QUESTION

Draw end position get Item rect size

Asked 2022-Mar-01 at 18:42

I'm trying to use ImGui (Java bindings) to fill up a empty space or fill the entire width of some UI but I can't seem to figure out how to/when to ask ImGui for the Item Rect Max and in some situations I end up with a small space that isn't filled in.

The code I using is here (it's too many lines to just add here) https://github.com/blockout22/VisualScripting/blob/main/src/main/java/visual/scripting/GraphWindow.java#L295

this is where I got the style from but I think I'm missing something https://github.com/thedmd/imgui-node-editor/blob/687a72f940c76cf5064e13fe55fa0408c18fcbe4/examples/blueprints-example/blueprints-example.cpp

I fixed this by checking for max width every time I add any new UI while creating the node

this was my solution https://github.com/blockout22/VisualScripting/commit/7cd045efbe5366d38431ee82122a5b16f4c1e447#diff-33432afab7c91a7783be97cc24d2de52a81870145ce3a3e9dad3cb260076c208

QUESTION

How to load ImGui image from byte array with opengl?

Asked 2022-Jan-17 at 10:13

I am trying to render an image in my c++ ImGui menu; I believe the end code would be something like ImGui::Image(ImTextureID, ImVec2(X, Y));. I already have a byte array that includes the image I want to render, but don't know how to go about loading it into that ImTextureID that's being passed in. I have found how to do it with Direct X using D3DXCreateTextureFromFileInMemoryEx but need to know the opengl equivalent for doing this.

...

ANSWER

Answered 2022-Jan-17 at 10:13

The 'ImTextureID' in ImGui::Image is simply an int, with a value corresponding to a texture that has been generated in your graphics environment (DirectX or OpenGL).

A way to do so in OpenGL is as follows (I'm not familiar with DirectX but I bet that 'D3DXCreateTextureFromFileInMemoryEx' does pretty much the same):

Generate the texture name (this 'name' is just an integer, and it is the integer that ImGui uses as ImTextureID) using glGenTextures()
Set UV sampling parameters for the newly generated texture using glTexParameteri()
Bind the texture to the currently active texture unit using glBindTexture()
Upload pixel data to the GPU using glTexImage2D()

Typically that would look like something like this:

QUESTION

UBO value changes value when passed to shader

Asked 2022-Jan-15 at 19:52

I am trying to update the value of a uniform variable within my shader using an ImGui slider however the value I pass in is correct on the CPU side but when its at the GPU it becomes a negative value. I give an example of how I am setting this all up where someVal is the value being passed to the GPU which represents the radius value in the image I show (Naming was changed to help make things slightly clearer). This is what I am currently doing

ANSWER

Answered 2022-Jan-15 at 19:52

I was taking in an array of samples which was set to 64 but in my shader I had set it to 32. This caused my other variables to receive weird values.

Assuming you downloaded imgui to a place called $IMGUI_DIR and the file that contains your main function is main.cpp, your compile commandline should look like the following: (the \ are just there to break up the command)

Meson compiling subprojects in debug mode

Asked 2021-Nov-18 at 22:20

I have a parent project and a subproject using meson. Quite sadly the subproject only builds in release mode. However, even if I set the parent project to debug using --reconfigure and check with configure that the build type is debug, it seems the NDEBUG macro is not defined for the subproject, which causes it to fail compilation.

Is there a way to enable debug builds for subprojects?

ANSWER

Answered 2021-Nov-18 at 22:20

This is currently not supported, as you could see from the table of core options, only 3 options are settable per subproject as of now: werror and default_library (since 0.54.0) and warning_level (since 0.56.0). And below in Specifying options per subproject you can find more details e.g. about order of applying.

Also I found from discussion in issue Subproject default_options are ignored one of the main contributor says:

Right now only a couple of options are allowed on a per-project basis: default_library, werror (and one more I can't remember off the top of my head). We keep adding more over time, but other ones are ignored, yes.
