However, if the surface is contained in a QWindow which is hosted with createWindowContainer(), or the obsoleted QGLWidget is used and it does cover the entire full screen window, then this problem does not occur. For example, QOpenGLWidget or QQuickWidget can trigger this. For example, menus may not appear correctly, or dialogs fail to show up.Ī window can use an OpenGL based surface either explicitly when setSurfaceType() is called, or when something that requires OpenGL is used inside the window, causing the whole window to be OpenGL based.
QT FULL SCREEN WINDOW WINDOWS
As a result, other top-level windows are not placed on top of the full screen window when they are made visible.
Due to limitations of the Windows DWM, compositing is not handled correctly for OpenGL based windows when going into full screen mode. When a window is using an OpenGL based surface and is appearing in full screen mode, problems can occur with other top-level windows which are part of the application. Example program: // Using SDL2 to create an application window #include "SDL.If you are experiencing strange problems with using special flags that modify the alignment of structure and union members (such as /Zp2) then you will need to recompile Qt with the flags set for the application as well. This function is available since SDL 2.0.0. This limitation may be removed in a future version of SDL. On non-Apple devices, SDL requires you to either not link to the Vulkan loader or link to a dynamic library version. If SDL_WINDOW_METAL is specified on an OS that does not support Metal, SDL_CreateWindow() will fail.
If SDL_WINDOW_VULKAN is specified and there isn't a working Vulkan driver, SDL_CreateWindow() will fail because SDL_Vulkan_LoadLibrary() will fail. If the window is created with any of the SDL_WINDOW_OPENGL or SDL_WINDOW_VULKAN flags, then the corresponding LoadLibrary function ( SDL_GL_LoadLibrary or SDL_Vulkan_LoadLibrary) is called and the corresponding UnloadLibrary function is called by SDL_DestroyWindow(). Window size is actually limited to 16384 x 16384 for all platforms at window creation. If the window is set fullscreen, the width and height parameters w and h will not be used. Note that when this flag is set, the drawable size can vary after the window is created and should be queried after major window events such as when the window is resized or moved between displays. Use SDL_GetWindowSize() to query the client area's size in screen coordinates, and SDL_GL_GetDrawableSize() or SDL_GetRendererOutputSize() to query the drawable size in pixels. If the window is created with the SDL_WINDOW_ALLOW_HIGHDPI flag, its size in pixels may differ from its size in screen coordinates on platforms with high-DPI support (e.g. On Apple's macOS, you must set the NSHighResolutionCapable ist property to YES, otherwise you will not receive a High-DPI OpenGL canvas. SDL_WINDOW_SHOWN may be queried later using SDL_GetWindowFlags(). The SDL_Window is implicitly shown if SDL_WINDOW_HIDDEN is not set. SDL_WINDOW_SHOWN is ignored by SDL_CreateWindow(). SDL_WINDOW_ALLOW_HIGHDPI: window should be created in high-DPI mode if supported (>= SDL 2.0.1).For my project I decided to use BasicApplication. The second step is selecting a name for your project and a location where to save it. SDL_WINDOW_INPUT_GRABBED: window has grabbed input focus The first step is to create a new project in Qt Creator from one of the available templates: For a graphical application you want to select the Qt Widgets Application template.SDL_WINDOW_MAXIMIZED: window is maximized.SDL_WINDOW_MINIMIZED: window is minimized.SDL_WINDOW_RESIZABLE: window can be resized.SDL_WINDOW_BORDERLESS: no window decoration.SDL_WINDOW_HIDDEN: window is not visible.SDL_WINDOW_METAL: window usable with a Metal instance.SDL_WINDOW_VULKAN: window usable with a Vulkan instance.SDL_WINDOW_OPENGL: window usable with an OpenGL context.SDL_WINDOW_FULLSCREEN_DESKTOP: fullscreen window at desktop resolution.SDL_WINDOW_FULLSCREEN: fullscreen window.Remarksįlags may be any of the following OR'd together: Returns the window that was created or NULL on failure call SDL_GetError() for more information.
