Programming :: Using "dialog " To Generate Menu Base On Dir Contents
Oct 20, 2010
I'm just messing around trying to create a script that will give me a menu driven method of selecting a file from a directory. After doing some searching around on the web, I found that the "dialog" command might be able to provide what I need, but I'm not sure exactly if what I want is possible.
I was messing around with the --menu option and am getting pretty close, but not exactly what I want. Here's a snip of what I've been working with:
Code:
This gets me the results I want for the first option in the list, but the rest comes out a bit weird, as it's taking the directory contents and applying to the "tag" field as well. In fact, if there wasn't a need for the tag field, it would probably be working exactly as I want it to.
I plan on messing around a bit more to see if there is a workaround, but figured I'd post this just in case someone else had accomplished something similar. Essentially, this will be embedded in a script where each file in my $DIR variable will show in the menu and the selected file will end up in a variable for later use.
I am envisioning a dialog menu with 2 sections, the top 2/3 a menu, then the bottom 1/3 is a message box. When you highlight a menu item it gives you a description of what it does in the message box. However I am not sure it is possible. Can this be done in BASH?
I was messing around with the opacity-brightness-saturation option in compiz and opcaity was set to 100%. Thus, everything that I click on is open, but invisible. I AM A GENIUS.
I am using Linux on my system. I don't have gui for my system, only console is there.
I have some task to create a menu box window using dialog in shell scripting.
I have to take input from user & save it in a file.
But this should like html form as e.g.
Name - ..................... email id - .................. phone - ...................... location - ...................
Submit Cancel
Such window should be displayed on console using dialog & then user will enter his information there as Name,email id, phone,etc & submit it, then it gets saved to a file. Here submit & cancle are buttons. I have to do it in bash shell scripting. Or give me some examples like the above with shell script code.
I tried Wubi, and all is fine, but when I choose Ubuntu on the boot menu, it shows some dialog, then just blank. its stays blank forever, so I had to shut the computer off.Then, I burned the Ubuntu iso to a CD and botted from it at startup. This at least showed the purpl-ish install screen. After I pressed enter over install, it went to the blank screen again. just black, nothing appeared.I'm not sure what the problem is. My laptop is fairly new, it shouldnt be having an issue to run it.I have 4Gb RAM, plenty of space on the hard drive, and a 1Gb video card...I have no clue what to do, as this is my first encounter with an Linux distro ever. help?
Is it possible to do the following in C/C++ in Linux:Without direct linking (my program should NOT depend on Qt or GTK), display a GTK or Qt based file dialog.The behaviour should be something like this when my program runs, when you want to open a file:The program scans whether you have Qt installed. If so, it somehow manages to link itself to Qt (e.g. dynamically loading the .so file) and display its file dialog and get the path from it. If Qt wasn't found, it tries the same with GTK. If that also wasn't found, it displays a less powerful replacement dialog instead (better than nothing).
Or is there any other simple way in Linux to get a standard file dialog somehow (similar to when compiling for Windows you can very easily get its standard file dialog, no matter what version of Windows, in your code, even if your program doesn't use any other Windows GUI at all).
Anyway, here is something that is puzzling me and cannot think up a good way around it: I call the constructor and show elements of LoginDialog in the constructor of my QMainWindow, like this:
LoginDialog is a QDialog and it does show up on application start... but... It is not active! The QMainWindow is the active window, even if I put lid->activateWindow();
So, the question is: how do I pop up this dialog on application start in such a way that it will show the LoginDialog on startup as active window?
I cannot seem to get if else statements to work. if $choice == Dog then i want it to say "you selected Dog" The variable choice has the value Dog in it as proved at the end by echo "yes $choice is $choice" following the error Code: ./test.sh: 37: [$choice: not found How do i get the conditional statement to work? What's wrong here? This is the full script:
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.
How do I generate sql result into xml ? Tried this way (shown below), but it generates all data into single column.
Code: Select allgenerate_xml() { Â Â Â Â f1=_tmp1 Â Â Â Â f2=_tmp2 Â Â Â Â cat $SQL_QUERY_OUT |sed -e 's/^"//g;s/"$//g;s/","/|/g'|tr '|' ' ' > $f1 Â Â Â Â [ -e $SQL_QUERY_OUT ] && rm $SQL_QUERY_OUT
Does anybody know how to generate excel charts from C, or if it's possible at all?
For example, if I had 2 arrays that I wanted to export to excel and graph against each other. I know how to export it to a csv file, that's no problem, but I have no idea where to start with generating a graph of the data. I can't seem to find any examples anywhere.
I'd appreciate if someone could point me in the right direction.
Just a simple example to show you what I mean code...
I have a file, two columns, first column has a list of 15000 (yes 15k) unique codes, second column has the afilliate codes of 60 locations repeated to fill out the 15000 rows of unique codes. I need to produce a nice neat paper voucher which will fit onto A6 (1/4 A4) and is ready to print. Each voucher has the unique code and corresponding location. So far I am thinking PHP will do the job. This does it somewhat, but doesn't let be split the fields between the ",". I did this so far in PHP
I am trying to generate pdf in thai language. i have installed thai package (extension in babel package). It is finally generating pdf in thai. but thai string are cming very long as compared to original string given in .tex file.
I need to generate random numbers using /dev/random in C. The numbers should be of type double (64-bit floating point).The functionality should be equal to linux command "od -An -N8 -t fD /dev/random", but written in C.The prototype should be "double drand(void);".
A script to generate random dates. It uses the year range 2006-2009, and truncates every month of the year to an ordinary February's 28 days, but otherwise it's pretty solid and safe.
I want to automate my System-installation. So i try to make a Script that will generate the /etc/motd. Now i have the Problem that the script has some variables and after the "Hostname, OS, HW, IP" the "stars" are anyware, but not there they should. The most problem is the $OS this string can verry long or verry short be. Fedora release 12 (Constantine) or RedHat 5.4 i can do that after the variables place the "stars" on the write position?
I have some c++ code and want to generate class diagrams using some tool which would scan the c++ code and generate diagrams. Is there any such open source tool to be used on linux machine?
If I have an array which its size is based on the user input, from some material, I need to use malloc function to allocate memory for that array what is known dynamic array. Don't forget to free it.hat's fine, however, I like to try things out even I know the program will crash.I have written some test program on my Mac using C language like this:int width = 0;//get user input, and assign the input value to width, for example, 3char * array_var[width];and width is an int, its value will be assigned by the user input. The point is, this program work as expected, for example, in command line, I input 3, then array_var length is 3, its size is 3 * sizeof(char *).
i try to understand this algorithm but i cann't. [URL] I encounter problem understand the algorithm of fixed base windowing exponentiation algorithm ? What is fixed base in the first place ? How this algorithm works ?
I want to write a program in C which will generate a maze randomly and find the solution for it ..
The idea behind is in [url]
How the 16 bit integer is stored in a variable..Earlier I wrote a program on trees and displayed it using dotty.. Is there any such tool to display a maze..I am using ubuntu 10.04.
i have spotted that script (something similar that i am looking for)
[URL]
and i just dont know how to use it.I am not a programmer myself and probably no need for learning that just to create one script! modify "wje_lq" script and run it. thing like : "Just redirect standard output to a file in the normal manner" ? and all this
