xlib

问题 So I want to make left mouse clicks using another pointing device (that can be created with e.g. xinput create-master mouse ) but those clicks shouldn't give focus to windows. This is what I got so far: (Compile this code with gcc -lX11 -lXtst -lXext -o test test.c and move your mouse over e.g. text that is inside of a text editor like Kate) #include <X11/Xlib.h> // Simulate mouse click void click (Display *display, int button) { // Create and setting up the event XEvent event; event.xbutton

问题 Ok, I need to use this for graphical programming, GUI, for cs 349 uwaterloo first assignment. I see random Xlib.h and Xutil.h files lying around on google search results. But no where does it say how I install or download Xlib from some website of something. I even tried to copy paste the Xlib.h onto a new files I created in my blank project and it has more than 100 errors. So... what do I do? 回答1: Simpliest way is to install cygwin - you'll get gcc + other tools (binutils, make, autotools)

问题 My application for X System stays in background (and in panel as indicator) and should popup whenever user hits a key, no matter whatever be the active window. Similar to Menu app. Tried the following: Listening for global key-combinations in python on Linux But can't find how to integrate this Gtk main loop. Global keybinding on X using Python gtk3 The only answer for this question is Python 2 and doesn't work. Mixing the above two, I got the following code: from Xlib.display import Display

问题 I want to draw some primitives on top of all windows on the screen. I've found some code in C and tried to port it to use python's xlib: from Xlib.display import Display from Xlib import X from Xlib import protocol display = Display(':0') root = display.screen().root gc = root.create_gc() root.fill_rectangle(gc, 100, 100, 500, 500) But nothing appears on the screen (however, the root window is assigned: grabbing keyboard after it works). How to do this correctly? 回答1: You can draw on root

问题 I want to write a simple Xlib program changing the mouse behavior (to give an example, invert vertical movement). I have a problem with capturing the events. I would like the code to capture changes in the controllers position (I move mouse upward, MotionEvent ) calculate new cursor position ( new_x -= difference_x ) set new cursor position ( move pointer down, XWarpPointer , prevent event generation here) The code below should capture a motion event every time the mouse is moved, but it

问题 When swapping between back and front buffers the content in the back buffer becomes undefined. I´d like to define it using the "windowing system", such as GLX, EGL, WGL. Using "native" renderer such as OpenGL (glClear) is my backup plan, don´t bother mentioning it. The reason it is backup is because I don´t want to mess with native rendering contexts. I´ll stick to X/GLX for this question but if you feel inclined to describe how to do it in other Environments then go ahead. From the Xlib

问题 I can see from various documentations that XCloseDisplay returns an integer, which I suspect to be an error code. What should I do with this value? Is it an error code? If so how do I handle the error? 回答1: I looked in the source code ( lib/X11/ClDisplay.c ) It says: return 0; So there's nothing you can really do with the return value. 来源： https://stackoverflow.com/questions/23083523/what-does-xclosedisplay-return
