After installing XQuartz you may add a symlink to your X11 installation folder by just entering ln -s /opt/X11/include/X11 /usr/local/include/X11 in terminal. That will fix the problem as well without changing any ruby script.
The problem lays in the communication between X Server and the Window Manager. When you call XCreateWindow or XCreateSimpleWindow, the X Server creates your window (not showing it until you explicitly map it on the screen by calling XMapWindow), and then the Window Manager is responsible for attaching all the decorations and buttons and system … Read more
xwininfo and xprop permits to retrieve what you want, but it is a little tricky. xwininfo permits to retrieve all known windows, and xprop to query X about a single window ID for your _NET_WM_PID parameter. So far, a hacky way to do it would be: #!/bin/sh findpid=$1 known_windows=$(xwininfo -root -children|sed -e ‘s/^ *//’|grep -E … Read more
One important decision is how you’re going to talk to the X server. You can use the Xlib bindings for your language of choice, or you can use the higher-level XCB bindings. (If you’re insane, you might open a socket to the X server directly.) To know how a window manager ought to behave, there … Read more
From the CLI you can use xwininfo -tree -root If you need to do this within your own code then you need to use the XQueryTree function from the Xlib library.
Install libxtst-dev package and you’ll be able to compile Chromium sources.
i don’t know much about chromium, but, I did work with X way back when 🙂 When you tell an X client to connect to :0, what you are saying is connect to port 6000 (or whatever your X server runs on) + 0, or port 6000 in this case. In fact, DISPLAY is IP:PORT … Read more
Try to install X11 via http://xquartz.macosforge.org/landing/ set the correct path to the X11 library for the compiler with: export CPPFLAGS=-I/opt/X11/include then try to reinstall ruby, passing to the compiler where gcc-4.2 is: CC=/usr/local/bin/gcc-4.2 rvm reinstall 1.8.7 Without CC I got a lot of segmentation faults.
The only way I know to do this is to traverse the tree of windows until you find what you’re looking for. Traversing isn’t hard (just see what xwininfo -root -tree does by looking at xwininfo.c if you need an example). But how do you identify the window you are looking for? Some applications set … Read more
