A transparent background means a transparent framebuffer, aka all the untouched fragments ?įor this purpose, the GLFW library was set using Window (the operating system is relevant to select the window handler library). A good way to start with GFLW is the great documentation available on the official page. Instead of the classic int main, the WinMain is used.There are a few things to notice on the previous code: Window = glfwCreateWindow(windowSizeW, windowSizeH, "Hello World", NULL, NULL) create a windowed mode window and its OpenGL context Int windowSizeW = 640, windowSizeH = 480 Int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, char*, int nShowCmd) change this to int main() to allow the console Then, a single hello world window drawing a quad is shown in the following code: #include The GLFW: Getting started is your starting point on this. The quad displayed is with Legacy OpenGL (not recommended).
#Tiddlydesktop borderless window code
However, to set my point is enough instead the boilerplate code using GLSL.
There are 2 variables with the width and height of the window (those should be used later). The output window of the previous code look like: Let's start adding things The first thing to include will be the transparent framebuffer parameter. This code should be written after the glfwInit and before the glfwCreateWindow instruction, as follows: glfwWindowHint(GLFW_TRANSPARENT_FRAMEBUFFER, GLFW_TRUE) Lamentably, it does not work at the first shot. Great, the further step is to extract the dimension of the output window (e.g. GlfwGetMonitorPos(monitors, &monitorX, &monitorY) WindowHeight = static_cast(videoMode->height / 16 * 9) WindowWidth = static_cast(videoMode->width / 1.5) GLFWmonitor** monitors = glfwGetMonitors(&count) Ĭonst GLFWvidmode* videoMode = glfwGetVideoMode(monitors) I am assuming that main monitor is in the 0 position These values are practical to set the position of the window: int count, windowWidth, windowHeight, monitorX, monitorY Expressly, we are assuming computation will be over the first monitor (indexing as zero). The latter thing to setup is the visibility window hint to false for subsequent window creation ? glfwWindowHint(GLFW_VISIBLE, GLFW_FALSE) Īfter this instruction is mandatory the creation of the window with the glfwCreateWindow command. #Tiddlydesktop borderless window windows#.
