I'd like build a GUI where every single pixel is under my control (i.e. not using the standard widgets that something like GTK+ provides). Renoise is a good example of what I'm looking to produce. Is getting down to the Xlib or XCB level the best way to go, or is it possible to achieve this with higher level frameworks like GTK+ (maybe ...

I've implemented a horizontal splitter widget in Xlib. I'm trying to grab the mouse when the user clicks & drags on the splitter bar (so that the user can dynamically move the split & thus resize the windows on either side of the splitter bar). I've used XGrabPointer() after receiving a left click, in hopes that all future mouse motion...

Hello, does anyone know what is XLib ZPixmap format for 32/24bit images/pixmaps. Is it RGB(A) or BGR(A), etc. or highly implementation dependent? ...
I am trying to write a simple program to act as my desktop background in Qt, I have made it all work fine apart from making it a Desktop Widget. I have no idea on how to do this, I don't mind using XLib or Qt for doing this, but if anyone has some suggestions I would be very happy. ...
I am trying to make a screenshot of a not visible window under X. My first attempt was to capture the window using xwd or import (from ImageMagick). Unfortunately when window is under some other windows the hidden parts are black. What's even worse is that when window is not on the current desktop I get a BadMatch error. The next thoug...
I'd like to be able to track which application is currently focused on my X11 display from Python. The intent is to tie it into a timetracking tool so that I can keep track of how much time I spend being unproductive. I already found this code at http://thpinfo.com/2007/09/x11-idle-time-and-focused-window-in.html: import Xlib.display d...
Hi, I'm a little confused on Xlib programming now. I started to use dwm (a lightweight window manager) a few weeks ago, and I'd like to pickup some Xlib programming books or online resource to customize the dwm. However, after Googling around the web, I don't see much new articles talking about Xlib?? The newest programming guide for ...
I want to render the contents of the window in to QWidget ( or QPixmap ) using XComposite and XRender. The Issue I'm facing is that I can't get the picture be rendered in the QWidget. The code below has been written using the following tutorial: http://ktown.kde.org/~fredrik/composite_howto.html The window ID is hardcoded, so there can b...
I would like to find out if a window has focus. I am using pyGTK and would be helpful to us that but have got some Xlib in my script aswell. I've used: self.window.add_events( gdk.FOCUS_CHANGE_MASK ) # It took me ages to research this self.window.connect("focus-in-event", self.helloworld) but this gives me the event every time the win...
Hi. I'm working on a I/O verification tool based on Linux in a game project. It is written in C++, and,since using the same I/O module as our game, it's based on OIS 1.2. Thus, though all I need is to print users' inputs on the console, I still need to create a window for OIS. So here comes my question: How can I create a mapped window ...
I'm making a fullscreen OpenGL application, and I want it to restore original desktop mode when user switches away from it, and to restore mode back when user switches to it. This looks like "FocusIn" and "FocusOut" events, but they are not suitable for this. Window will get "FocusOut" as soon as user presses Alt+Tab and window selector ...
I am writing a simple window manager using xlib. The code reparents client windows into a window slightly larger than the client window called frame window. I am trying to implement a click to focus policy. I am getting buttonpress events when the mouse button is pressed in the frame window and am able to raise the frame window on button...

I want to write some OpenGL 3.2, likely also OpenGL 4 stuff on Linux, and I just saw that libsdl 1.2 (the latest stable release) supports only 2.x. LibSDL 1.3 (which is in development) should support it, but it'll be a while before it gets into mainstream distributions. Is there any library out there right now which allows me to create a...
I want to get mapping-independent key codes, but documentation says that "keycode" in XKeyEvent structure depends on hardware and driver and I can't rely on it. How can I get some portable key codes like VK_* in Windows? ...
Hi All, We have a 32bit Motif Gui application. Now we ported the application from Solaris to Linux and the system is crashing very frequently. On our analysis we could find that this issue happened when we are closing the forms in our application. When the forms are closed we will delete the forms and will call the function XtDestroyWidg...
