If maxwidth or maxheight are None, no maximum size is enforced. I found that when you set GLFW_CURSOR_DISABLED by glfwSetInputMode()in moving mouse, sometimes you will find that there is a big offset between the cursor position obtained from glfwGetCursorPos before and after glfwPollEvents is called. Errors Possible errors include GLFW_NOT_INITIALIZED and GLFW_PLATFORM_ERROR. See also Window visibility glfwShowWindow Since Added in version 3. See also Path drop input Main thread wake-up. When. Is it possible to hide the glfw window? I want to do this so I can ‘centre’ the window on the desktop without it appearing briefly at the top/left. Note it also works if I move the mouse after the keypress (and GLFW provides mechanisms for identifying what version of GLFW your application was compiled against as well as what version it is currently running against. Follow me on Twitter: https://twitter. // // This is incremented when features are added to the API but it remains // backward-compatible. This is useful for implementing for example 3D camera controls. I verified that it is The pixels are 32-bit, little-endian, non-premultiplied RGBA, i. This is the default mode. And using glfwSetInputMode(window, GLFW_CURSOR, GLFW_CURSOR_HIDDEN); Then without the reference mouse, the brain somehow gets used to the lag and it the lag disappears. . Thus I ran the command glfwSetInputMode(window,GLFW_CURSOR,GLFW_CURSOR_DISABLE) to have opengl recenter the mouse for me and gives back the cursor position through a call back method which I set using the method glfwSetCursorCallback(window,callbackPos) glfw seems to either support a cursor, or getting full mouse input but not both. This bug Is it possible to hide the glfw window? I want to do this so I can ‘centre’ the window on the desktop without it appearing briefly at the top/left. GLFW now provides the glfwPostEmptyEvent function for posting an empty event from another thread to the main thread event queue, causing Thanks for watching. For instance, if width and height are both zero, GLFW will use a window resolution of 640x480. The same code does hide the mouse cursor under Windows. Reload to refresh your session.

If you are loading GLFW dynamically (not just linking dynamically), you can use this to verify that the library binary is compatible with your application. As a result, `set_cursor` calls were simply ignored by the compositor. The reason why was that ImGui (UI Library im using) was showing the cursor every single frame. 1) I've attached example code tha View Source const ( // VersionMajor : The major version number of the GLFW library. On the other hand, if I use glfwGetCursorPos(window, &cposx, &cposy); it is moving around the screen. It would be fine to run By default, the cursor mode is GLFW_CURSOR_NORMAL, meaning the regular arrow cursor (or another cursor set with glfwSetCursor) is used and cursor motion is not limited. I position a bitmap at read mouse position, but the resoults aren’t as I expect - mouse either doesn’t move or moves totally strange. That is, they hardly change at all.

Note that the mouse cursor is still hidden; Expected behavior: I would not expect kitty to ever hide the mouse cursor when it does not have focus. The simplest is to call glfwGetCursorPosition in the function you need access to the position. Is there any way of enabling the cursor while in full-screen mode? I feel like I’m missing something because the only other AutoHideMouseCursor is a small portable Windows application that allows you to hide the mouse cursor, if this does not move. For full screen windows, this function updates the resolution of A value of None is equivalent to GLFW_DONT_CARE. Share. window: GLFW_IBEAM_CURSOR 0x00036002 The text input I-beam cursor shape. I set the pointer input mode to “disabled” like this : glfwSetInputMode(window, GLFW_CURSOR, GLFW_CURSOR_DISABLED); Then, I enable the “raw mouse motion” like this (tested if available before) : glfwSetInputMode(window, GLFW_RAW_MOUSE_MOTION, GLFW_TRUE); But However, once I switched to GLFW_CURSOR_HIDDEN it worked, but it wouldn't hide the cursor. For more information on bundles, see the Bundle Programming Guide Here is the detailed instruction how to solve it under Visual Studio without rewriting your code:. Sign in Product GitHub Copilot. Here is my camera code for handling mouse input for reference: I’ve encountered an issue where i can’t update my cursor position through glfwSetCursorPos. cursorMode. The top-left to bottom-right diagonal resize/move shape. cpp file along with the callback or in as GLFW_IBEAM_CURSOR 0x00036002 The text input I-beam cursor shape. 1 with Ubuntu, hiding the mouse cursor via glfwSetInputMode () does not have any effect. One is that MOUSE_VIRTUAL_DESKTOP is weird, but that's not all. 4? Is there any timeframe mast4as wrote on Monday, September 29, 2014: Is it possible in GLFW to change the mouse cursor shape? If so how? Thank you. But with vista it does not hide the cursor. The @ref GLFWwindow object encapsulates both a window and a context. Specs: Amd Ryzen 5 2500U with Vega 8 GPU; 8GB ddr4 ram; Os: Arch Linux; DE: KDE OS X: The GLFW window has no icon, as it is not a document window, but the dock icon will be the same as the application bundle's icon. That's ok if I can draw the cursor myself when I want but I cannot find any function GLFW_IBEAM_CURSOR 0x00036002 The text input I-beam cursor shape. If the cursor is disabled (with When using GLFW_CURSOR_DISABLED and raw motion enabled, we can get the unaccelerated delta x and y motion of the cursor indirectly, by substracting current position of the cursor from previous. By default, the cursor mode is GLFW_CURSOR_NORMAL, meaning the regular arrow cursor (or another cursor set with glfwSetCursor) is used and cursor motion is not limited. We have the GLFW_CURSOR_DISABLED which is great and all, but I was hoping someone could add a feature (if not already existing, from my research tells me no) which can still lock the cursor, but not hide it, while detecting mouse movement. GLFW tries to open a window that best matches the requested parameters. I've tried doing some research and trying to find out why the In my simple windowed app I'm hiding the mouse cursor using glfwDisable( GLFW_MOUSE_CURSOR ); This is working as expected, until I ran it on a PC with SW In my simple windowed app I’m hiding the mouse cursor using glfwDisable ( GLFW_MOUSE_CURSOR ); This is working as expected, until I ran it on a PC with SW I'm using this to set the cursor on the center of the screen to be able to pan the view around using mouse input like any other 3d game: glfwSetCursorPos(WINDOW, To constrain the cursor you could disable the cursor and draw your own - this is the approach used by most games, see this post on some approaches to drawing your own Possible errors include GLFW_NOT_INITIALIZED, GLFW_INVALID_ENUM, GLFW_INVALID_VALUE, GLFW_PLATFORM_ERROR and I’m using GLFW and want to create own cursor bitmap, so i disable showing cursor. GLFW_TRANSPARENT_FRAMEBUFFER specifies whether the window framebuffer will be transparent. The mode must be one of GLFW_CURSOR, GLFW_STICKY_KEYS, GLFW_STICKY_MOUSE_BUTTONS, GLFW_LOCK_KEY_MODS or GLFW_RAW_MOUSE_MOTION. Find and fix vulnerabilities Actions. This would be a much better solution than actually drawing the cursor manually with OpenGL, because that would require a SwapBuffers() every time the nobody wrote on Sunday, September 16, 2007: I’m just wondering, since this is making it impossible to do my app. If bShow is TRUE, the display count is incremented by one. glfwSetInputMode ( mainwindow, GLFW_CURSOR, GLFW_CURSOR_HIDDEN ); Thanks. In this case GLFW_CURSOR_DISABLED behaves like GLFW_CURSOR_HIDDEN. #define GLFW_VRESIZE_CURSOR 0x00036006 Add a cursor mode that restricts the cursor to the client area of the window. I think I just will use my own image cursors (including "empty" cursor instead of GLFW_CURSOR_DISABLED) for all situations. Reproduces when moving the cursor via Synergy (Windows server, macOS client). Thread safety This function must Documentation for glfw-n-api. On the other hand setting GLFW_CURSOR to GLFW_CURSOR_DISABLED works fine. For example, with the cursor enabled (default) the glfwscroll_callback does nothing. Errors Possible errors include GLFW_NOT_INITIALIZED, GLFW_INVALID_ENUM and GLFW_PLATFORM_ERROR. Let me know if you need any additional info about Wayland + Vulkan bugs. If depthbits is zero Documentation for glfw-n-api. 108. GLFW_CENTER_CURSOR. glfw-n-api ; glfwGetCursorPos; Function glfwGetCursorPos. If the mode is GLFW_CURSOR, the value must be one of The cursor_pos_callback is only called when the mouse is moved, same as how button callbacks are called only when a button is used. This guide introduces the window related functions of GLFW. One of GLFW_CURSOR, GLFW_STICKY_KEYS, GLFW_STICKY_MOUSE_BUTTONS, GLFW_LOCK_KEY_MODS or GLFW_RAW_MOUSE_MOTION. Improve this answer. It is even Hi, I’m using GLFW and want to create own cursor bitmap, so i disable showing cursor. Someone with time and motivation could try getting it to work. Hiding the Cursor / Warp Mouse (SDL 1. Variables @:value(cast 0x00034001) @:enum @:impl inline read only Normal:CursorMode = 0x00034001. Move the cursor. I try to use the feature glfwDisable(GLFW_MOUSE_CURSOR); and it works great with Windows XP. They are created with @ref glfwCreateWindow By default, the cursor mode is GLFW_CURSOR_NORMAL, meaning the regular arrow cursor (or another cursor set with glfwSetCursor) is used and cursor motion is not limited. However, when this environment variable is missing it seems to set it to an odd size instead of directly requesting size from the compositor. void glfwDestroyCursor (GLFWcursor *cursor) Destroys a cursor. I position a bitmap at read mouse position, but the resoults aren’t as I expect - mouse When using GLFW 3. 4. And using During a search where I wanted to start creating my own images for diagonal resize arrows and various other standard cursor shapes, I found the following result: GLFW: Standard cursor shapes The URL mentions 3. 10 and void glfwSetWindowMonitor(GLFWwindow *window, GLFWmonitor *monitor, int xpos, int ypos, int width, int height, int refreshRate) However, GLFW is passing in the serial number of the latest received event, which does not meet the protocol spec. But I wonder if there any plans for callback to get it directly, like the relative motion callback on Wayland for example? I’m currently trying to use this to set up a simple crosshair cursor: GLFWcursor* crosshairCursor = glfwCreateStandardCursor(GLFW_CROSSHAIR_CURSOR); glfwSetCursor(window, crosshairCursor); It works, and has saved me time doing it with OpenGL lines, but I find that the crosshair cursor is very janky, despite the program performing well The glfw viewport however seems to pick up cursor size from XCURSOR_SIZE environment variable. However, whatever the direction I’m moving the mouse, the position recieved in the callback glfwSetCursorPosCallback(window, Hi @dougbinks, Thanks for the quickest reply. Displays or hides the cursor. @elmindreda: Well then. Unless the time has been set using glfwSetTime it measures time elapsed since GLFW was initialized. 2 System: Linux Mint 16 If I first disable the mouse cursor with glfwDisable(GLFW_MOUSE_CURSOR), the callback registered by glfwSetMousePosCallback() is still called as expected, but the mouse coordinates do not update consistently. is glfw able to use one (mouse callbacks?) - thanks mouse capturing works but doesn't hide mouse cursor itself from view. e DEF-1619 ), but I can’t find any information on the opposite. Disable the mouse cursor within a program. Thread safety This function must only be called from the main thread. In project Settings when I enable the “fullscreen” option and launch my game there is no visible cursor on the screen. The return value specifies the new display counter. nobody wrote on Saturday, March 24, 2007: Hi to all, first of all thanks for this great piece of software! I use it to implement a game and i am running into a problem on windows vista. #define GLFW_VRESIZE_CURSOR I am creating a 3D game using LWJGL3, and I want the window loaded in the background and hidden, wait for my game setup and only than showing up. I disabled the cursor and instead showed a line drawn from the center to the clamped position (I also slowy re-centered the cursor if it was close to the middle so the user could get back to flying straight). [in] value: The new value of the specified input mode. The next easiest would be to use global data (either in the main. If you wish to implement mouse motion based camera controls or other input schemes that require unlimited mouse movement, set the cursor mode to GLFW_CURSOR_DISABLED . Unfortunately the difference between GLFW_CURSOR_DISABLED and GLFW_CURSOR_NORMAL is not just that the cursor is disabled or not, but also in DISABLED mode it is not possible the move the cursor over the boundaries of the window, instead the cursor is "captured". Every time WM_MOUSEMOVE is called, mouse is moved as an offset compared t Sometimes it's necessary to have absolute mouse coordinates, and GLFW does not seem to provide any way to get this currently. shot511 wrote on Saturday, December 14, 2013: Hello, Is there any mouse motion/move callback in GLFW? I can’t find it in documentation ;/ I want to get mouse cursor position every time mouse moves. #define GLFW_HRESIZE_CURSOR 0x00036005: The horizontal resize arrow shape. If sticky keys are enabled, a key press will ensure that glfwGetKey returns For different reasons I would like to disable the cursor with glfwSetInputMode(window, GLFW_CURSOR, GLFW_CURSOR_DISABLED); This disables the mouse, makes the "mouse_move. 9 from Arch Linux repos, GNOME Wayland session. The problem is that if I am not in full screen and I move my mouse extremely fast to one side, I can manage to escape the window and the mouse cursor will You don’t need to use C++ std:: types, you just need to be able to access the data in your main rendering loop. If the mode is GLFW_STICKY_KEYS, the value must be either GLFW_TRUE to enable sticky keys, or GLFW_FALSE to disable it. 1 X11 GLX EGL clock_gettime /dev/js Xf86vm shared I’m trying to implement FPS camera using glfwSetInputMode(window, GLFW_CURSOR, GLFW_CURSOR_DISABLED); feature of GLFW. X11: This shape is provided by a newer standard By default, the cursor mode is GLFW_CURSOR_NORMAL, meaning the regular arrow cursor (or another cursor set with glfwSetCursor) is used and cursor motion is not limited. It make sense unless after unhide i do GLFW_CURSOR_HIDDEN makes the cursor invisible when it is over the client area of the window but does not restrict the cursor from leaving. If the cursor mode is GLFW_CURSOR_DISABLED then the cursor position is unconstrained and limited only by the minimum and maximum values of a double. I just had the comment out the line in ImGui that did this. Once the screenshot is We have the GLFW_CURSOR_DISABLED which is great and all, but I was hoping someone could add a feature (if not already existing, from my research tells me no) which can The top-left to bottom-right diagonal resize/move shape. self, GLFW_CURSOR, GLFW_CURSOR_DISABLED); but the cursor is not locked, and moves outside of the window, constricting 360 degrees+ camera movement. mouse @:nullSafety(Strict) @:enum. 04 LTS, glfw Hide Window; glfw Iconify Window; glfw Init; glfw Init Hint; glfw Joystick Is Gamepad; glfw Joystick Present; glfw Make Context Current; glfw Maximize Window; glfw Poll Events; glfw Post Empty Event; glfw Raw Mouse Motion Supported; glfw Request Window Attention; glfw Restore Window; glfw Set Char Callback; glfw Set Char Mods Callback; glfw Set Clipboard String; glfw Little demo using Dear ImGui and OpenCV. Hide GLUT window. The standard cursor callback position is relative to the top-left corner of the window client area so as you move the window under the cursor you should see it stay constant. The pixels are 32-bit, little-endian, non-premultiplied RGBA, i. 7. 7 and hack it up to When the cursor mode is set to GLFW_CURSOR_DISABLED, the virtual mouse position provided by the cursor position callback is inconsistent. I believe it’s GLFW 2 still so you can just call their functions maybe. Nothing is working, can someone please help me set up a callback? I’m following GLFW: Input guide and I cannot find any useful examples of how to use this in my own code. glfwSetInputMode(window. It seems that kitty is too aggressively hiding the mouse cursor, even when it doesn't Hi, Im writing a cnc interpreter - i have most of what i need, mouse input working, keyboard input working. With glfwDisable (GLFW_MOUSE_CURSOR); but i cant see the mouse cursor when the mouse leaves the window so i use glfwEnable (GLFW_MOUSE_CURSOR); to enable it When Command+Shift+4 is pressed, GLFW makes the mouse cursor visible, restores it's last position, and allows it to move - just like when the window loses focus. ; It’s possible that Moving a window via the title bar forces the mouse into a fake GLFW_CURSOR_NORMAL after being in GLFW_CURSOR_HIDDEN mode and the cursor is able to leave the window frame whilst window is still in focus. Errors Possible errors include GLFW_NOT_INITIALIZED, GLFW_INVALID_ENUM and I have enabled raw mouse motion via: glfwSetInputMode(this->glfwWindow, GLFW_CURSOR, GLFW_CURSOR_DISABLED); glfwSetInputMode(this->glfwWindow, GLFW_RAW_MOUSE_MOTION, GLFW_TRUE); And it works great on 2/3 machines I have run my application on. 4 version by building with CMake.

Documentation for glfw-n-api. The counter-func How to hide mouse cursor using JOGL2? 27. You signed out in another tab or window. Being able to call glfwGetCursorPos() without a window handle or with a 0 window handle and getting back the absolute mouse coordinates in the virtual desktop if the cursor is enabled would be ideal. If bShow is FALSE, the display count is decremented by one. The resolution of the timer is system dependent, but is usually on the GLFW_CURSOR // See Cursor mode values StickyKeysMode InputMode = C. I'm using glfw-wayland 3. GLFW_CURSOR_DISABLED hides and grabs the cursor, providing virtual and unlimited cursor movement.
