Programming :: Grabbing Window Content Requires Drawable
Apr 9, 2010
I'd like to write a C/C++ program, that would grab content of window (in form of pixmap), which belongs to another application and do something with it. However, I ran into problems already at the beginning. In all toolkits I have searched through, I only found one function that claims to do what I want, namely XGetImage from Xlib. However, among other parameters like Display, coordinates, etc., it requires a Drawable. How do I specify a Drawable, that would correspond to the window I want to grab content of? Is there any easier way to achieve this?

I want to display an un-intrusive graphical dialog to notify the workstation user that a bash script has finished running. It should be "top level", so visible to the user when it appears but should not grab focus, so the user can continue working in the current window and dismiss the notification when convenient. Researching gdialog, xdialog, xmessage and zenity it seems none of them can do this; they all grab focus.

Running 10.04 64-bit. After logging on, the title bars around all the windows are missing. Adding "metacity --replace" as a startup command resolves the problem, but something's obviously wrong.
Doesn't occur on my other computer, so probably hardware related.
see attached checkbox-generated submission.xml.gz for hardware report.

I"m running 10.04 on a netbook. I switched my Java look and feel to Nimbus and now my java application opens with most of the buttons and window content missing. The main menu is there, but otherwise the main form is mostly blank. If I restart the application (not my computer) 2-3 times, the problem is resolved until the next time I have to launch the java app. I did not see this issue before changing the look & feel setting for Java. But the GTK l&F doesn't work for other reasons, so I was forced to make a change.
I'm running compiz and I know the blank windows in Java apps was a common problem a while back. I'm not sure if what I'm seeing is related to that old problem or is something different.

My users need to run an application which was build with newer GLIBC_2.11, while my system only gets GLIBC_2.4. It shows error "cannot find libc.so.6 GLIBC_2.11" whenever I run it. I cannot upgrade the system, so I have tried building Glibc 2.11 (for example:/opt/glibc-2.11) to another directory, but when I point LD_LIBRARY_PATH to /opt/glibc-2.11, I cannot run any commands because of error invalid LFS ABI. I also tried using LD_PRELOAD, but it does not work. Please help me, how can I fix this problem.

My project looks like this:
Home
The Team [no-page]
-X
-Y
-Z
Projects [no-page]
-Coding [no-page]
--A
--B
--C
-Desing [no-page]
--E
--F
-Security [no-page]
--G
--H
Note: the Code/Design/Security projects pages (A,B,C,D...) will be at start around 35 pages, and will grow. My index.php is something like this:
PHP Code: .....
What I would like to know is how to build the content (the home-main.php)? Do it dynamically based on a link something like this index.php?page=coding_b, and put in the index.php page a number of 35 if/else statements to cover all the project pages or ... static, creating every page for the projects menu when I create the menu? I check if a page 'pro-co-a.php' exists, if not I create it based on some template and do the query to get the content from db or? How to organize the pages, if using static page?

I have a problem to use echo to display the content of a variable.
This is what I do:
Code:
#!/bin/bash
USAGE="Usage: name [OPTIONS] [DIRECTORIES]"
echo $USAGE
When I run this little script I get the following output:
Usage: name [OPTIONS] R
So I think that [DI might be some sort of escape sequence. But I do not know how to unescape it. Does anyone have a hint for me?

What's the best command to use to grab just a regular expression from some text input? I've got is some input is in the form:
<uninteresting><start-marker><good stuff><end-marker><uninteresting>
I can construct a RE to match <start-marker>.*<end-marker>, but is there a utility that would return *just* the <good stuff> I'm interested in? I realise that the alternative is something along the lines of:
Code:
cat <input-file> | awk -F'start-marker' 'print ${2}' | awk -F'end-marker' 'print ${1}'
but it would be better if I could do it all in one go.

I've got a basic install (i.e., nothing fancy, no compwiz or whatever) of 10.4 (64 bit) on my computer, running gnome desktop. I find it very difficult to "grab" the edge of a window, when I want to resize it longer or wider and frequently I just wind up selecting the window below it when I try to drag it wider or longer. Is there a way to increase the border area in which that arrow-pointing-to-edge (as opposed to the usual cursor) appears to make it easier to grab the damn thing?

I want to be able to grab some text from a directory listing in a bash script, and then apply that text to future commands in the same script. For instance, say I do "ls -lais /media/Movies" and get:
2147560409 712544 -rwxr-x--- 1 root users 729645056 1999-03-07 11:45 Young Guns (1987).avi
2147560410 712400 -rwxr-x--- 1 root users 729497600 2002-01-09 01:11 Young Guns II (1990).avi
Then say I want to grab the year from this output and then use that information as part of the command to modify the file timestamp, such as:
touch "Young Guns (1987).avi" -t 198701011200
touch "Young Guns II (1990).avi" -t 199001011200
So that the result of ls -lais is:
2147560409 712544 -rwxr-x--- 1 root users 729645056 1987-01-01 12:00 Young Guns (1987).avi
2147560410 712400 -rwxr-x--- 1 root users 729497600 1990-01-01 12:00 Young Guns II (1990).avi
Anyway, that's just one example, but I often find myself needing to do this type of thing, and I'm sure its possible, just not really done enough scripting recently to know how to do it.
