What's the fastest way to create a two button GUI? [Archive]

Well, basically I want a program that looks like the first screenshot (that isn't an actuall program, just edited another screenshot) and it needs to do the following:
If the first button is clicked, it will run the following script:

#! /bin/bash
mplayer 'http://citadelcc-karn-fm.wm.llnwd.net/citadelcc_KARN_FM?MSWMExt=.asf' -dumpstream -dumpfile recording.asfAnd when the second button is pressed,

!#/bin/bash

killall mplayer(Please let me know if there is a more efficient way of stopping just that "mplayer" from recording)

If you know more about programming than I do, (almost nothing :) ) please reply!

Thanks!

EDIT: sorry, forgot the screenshot, I'm working on it!

There is a program just for this purpose, zenity.
man zenity

Do they have a GUI for doing it? I am not a good programmer.. Here's the original thread. http://ubuntuforums.org/showthread.php?t=1245479&page=1 (http://ubuntuforums.org/showthread.php?t=1245479&page=3)

The point is - if you had looked at the man pages for zenity as suggested - is that zenity is a simple way of creating GUIs from bash scripts.

so you could relatively simply write a bash scriot that creates a GUI exactly as you required, and where the buttons do exactly what you want them to do.

nope. i don't have mplayer so untested:

#!/bin/sh
read=`zenity --list --title='Stream Recorder' --column=Action Record Stop`

if [ $read = "Record" ]; then
mplayer 'http://citadelcc-karn-fm.wm.llnwd.net/citadelcc_KARN_FM?MSWMExt=.asf' -dumpstream -dumpfile recording.asf
fi

if [ $read = "Stop" ]; then
killall mplayer
fi

What's that, a script?
I ran it as one and it showed screenshot one. I tried double-clicking the buttons and it does something apparently, but I don't know where it puts the output file.

I see. I had looked at the man pages first thing, just wondered if they had a GUI frontend for Zenity.

yup, a zenity script that does what you asked it to do.

run this part:
zenity --list --title='Stream Recorder' --column=Action Record Stop

in a terminal to see what it looks like.

i'll do a xmessage 1 in a minute, which is more of the button look.

using xmessage:

#!/bin/sh
read=`xmessage -fn 9x15 -g -5+10 "Stream Recorder" -buttons Record,Stop,Cancel -print`

if [ $read = "Record" ]; then
mplayer 'http://citadelcc-karn-fm.wm.llnwd.net/citadelcc_KARN_FM?MSWMExt=.asf' -dumpstream -dumpfile recording.asf
fi

if [ $read = "Stop" ]; then
killall mplayer
fi

if [ $read = "Cancel" ]; then
exit 0
fi

create folder named "bin" in your home folder, put your scripts in there. log out & back in. then create your launcher.

i just modified my scripts to do what you want.

See the attached script.

To run it:

That looks great, is there a way to take out the "Shutdown Options" thingy and maybe name the window differently? It's fine as it is, but I am something of a tweaker. :)
EDIT: Uh-oh, looks like something malfunctioned. When I click record in the xmessage dialog, the window shuts down and five of the screenshot 1 dialogs pop up.

are you running it as root?

Thanks for changing the script. Just one thing left- the window shuts down when you click record. I wish it would stay on until you told it to Stop.

EDIT: I was not running it as root, but when you edited the first script, it fixed something. Now there are no error messages. Good job! Still the problem with rapid shutdown, though.

it would be in your home/you/recording.asf, if it's not then something is wrong with your command:
mplayer 'http://citadelcc-karn-fm.wm.llnwd.net/citadelcc_KARN_FM?MSWMExt=.asf' -dumpstream -dumpfile recording.asf

nothing can be done about the exit, there simple scripts.
i'm thinking maybe make it 2 part, for example: the first will just say "Record", that would run the script & open another window with "Stop". could you live with that? which 1 you want zenity or xmessage ?

it's 1:30pm here in hawaii, but i just went to bed at around 6:00am.

I did but it appears that the website the OP wants to record from is down.

As for what it does:

#!/usr/bin/env bash

### This uses zenity to create a popup window that asks
### the user what they want to do.
RES=`zenity --question --text="What do you want to do?" --cancel-label="Stop Recording" --ok-label="Start Recording"`

### zenity returns a number based on what the user clicked
### 0 = Ok
### 1 = Cancel
### -1 = If the window was destroyed in some strange way.
case $? in
0)
### This is the command you gave to record
`mplayer 'http://citadelcc-karn-fm.wm.llnwd.net/citadelcc_KARN_FM?MSWMExt=.asf' \
-dumpstream -dumpfile recording.asf `
;;
1)
### This obviously kills mplayer.
`killall mplayer`;;
-1)
echo "no response";;
esac

it's okay.
try this:

xmessage:

#!/bin/sh
read=`xmessage -fn 9x15 -g -5+10 "Stream Recorder" -buttons Record,Cancel -print`

if [ $read = "Record" ]; then
mplayer 'http://citadelcc-karn-fm.wm.llnwd.net/citadelcc_KARN_FM?MSWMExt=.asf' -dumpstream -dumpfile ~/recording.asf &
xmessage -fn 9x15 -g -5+10 "Stop Recorder" -buttons Stop;killall mplayer
fi

if [ $read = "Cancel" ]; then
exit 0
fi

i forgot to mention, if you want it the pretty gtk+ we can use "gmessage" instead, but gmessage is not installed in a default system so you would have to install it with apt-get or synaptic. just letting you know.

Ok, I fixed the script, here it is:

#!/usr/bin/env bash
RES=`zenity --question --text="What do you want to do?" --cancel-label="Stop Recording" --ok-label="Start Recording"`
case $? in
0)
mplayer 'http://citadelcc-karn-fm.wm.llnwd.net/citadelcc_KARN_FM?MSWMExt=.asf' -dumpstream -dumpfile recording.asf ;;
1)
killall mplayer;;
-1)
echo "no response";;
esac

I tested this and it works. It saves the recording in whatever directory its run from.

What version of zenity are you running?

i think you should install gmessage:
sudo apt-get install gmessage

with gmessage:

#!/bin/sh
read=`gmessage -center "Stream Recorder" -buttons Record,Cancel -print`

if [ $read = "Record" ]; then
mplayer 'http://citadelcc-karn-fm.wm.llnwd.net/citadelcc_KARN_FM?MSWMExt=.asf' -dumpstream -dumpfile ~/recording.asf &
gmessage -center "Stop Recorder" -buttons Stop;killall mplayer
fi

if [ $read = "Cancel" ]; then
exit 0
fi

example of my xmessage converted to gmessage, big difference in looks & speed:

What version of zenity are you running?

2.22.1-2 on debian lenny.

i don't see "--cancel-label" & "--ok-label" in the man page for my version, the first part is fine "zenity --question --text="What do you want to do?""

hey, i apologize for my wording, not trying to be confrontational. just got out of the shower so i'm a little more awake & i can see that what i put may not have been in a friendly way. again sorry.

Very nice, but I wish the dialog box would stay up when you clicked the button Start Recording and shut down when you click Stop Recording. Also it would be nice if there was another button to "Play Recorded File." (In that case you would probably want to disable all "dialog shutdown" commands) Another thing is that it does not drop the file in the folder I run the script from, (/home/myusrname/bin) but instead saves it as "/home/myusrname/Documents/recording.asf" for some reason. Yet another "thing" is that it saves the file as .asf, and if you try playing it, you will see the problem right away- you can't rewind or fast forward without it shooting you back to the beginning of the file. *Sigh* if only I could make it transcode to mp3 automatically...

Does this radio station have a .m3u stream? If it does, that makes it really easy to save it to an mp3 file.

BTW it is not possible with zenity to make the window stay open.
If you really want that you would have to use a real programming language.

kerry_s

October 1st, 2009, 03:31 AM

i agree, you would actually be writing a program, little scripts no problem, a whole program, your on your own. :lolflag:

like i said, you can us multiple scripts to get the same effect.

the download location is determined by the command. so:
mplayer 'http://citadelcc-karn-fm.wm.llnwd.net/citadelcc_KARN_FM?MSWMExt=.asf' -dumpstream -dumpfile /home/myusrname/Documents/recording.asf

should get it where you want.

i hope you have the mplayer gui? added it to the script should play when you stop.

#!/bin/sh
read=`gmessage -center "Stream Recorder" -buttons Record,Cancel -print`

if [ $read = "Record" ]; then
mplayer 'http://citadelcc-karn-fm.wm.llnwd.net/citadelcc_KARN_FM?MSWMExt=.asf' -dumpstream -dumpfile ~/Documents/recording.asf &
gmessage -center "Stop Recorder" -buttons Stop;killall mplayer; gmplayer ~/Documents/recording.asf

That's not entirely good news...:( No, the stream does not have an .m3u stream. (That I know of, anyway.)
And about the "it's not possible to keep the window open with zenity" thing.... That is rather inconvenient. I don't mind the graphics on Kerry's dialog, that is fine, so I guess I will use it. However, there are several video/audio convertors for Kubuntu. (That's the one I'm using right now.) Don't you think we could somehow add to the script the command-line options for WinFF (that's a command-based convertor I use) to convert the asf file to mp3? Once again, whatever the answer, thanks for all the help, I would still be doing research if you guys had not helped. :)

EDIT:There could be a button next to "Stop Recording" to "Convert To Mp3" (or it could do it automatically, doesn't matter to me)

#!/bin/sh
read=`gmessage -center "Stream Recorder" -buttons Record,Cancel -print`

if [ $read = "Record" ]; then
mplayer 'http://citadelcc-karn-fm.wm.llnwd.net/citadelcc_KARN_FM?MSWMExt=.asf' -dumpstream -dumpfile ~/Documents/recording.asf &
gmessage -center "Stop Recorder" -buttons Stop;killall mplayer; gmplayer ~/Documents/recording.asf
fi

exit 0
fi

Thanks, Kerry. That script does everything I expected to do from post #1. However, if you have some free time, could you or "Days_Of_Ruin" add the converting process to the script? I think this link (http://www.smorgasbord.net/converting-video-in-linux-using-ffmpeg-and-mencoder/) will tell you all you need to know...
The command to actually convert the file to mp3 should go like this: ffmpeg -i /home/halstan/Documents/recording.asf -f mp3 /home/halstan/Music/KARNHD.mp3 (I added the username, you can put that in the script, but don't misuse it, please; this is my Dad's computer)

EDIT: I tested that boldened command and it worked great. The file is now an Mp3, and plays like a normal mp3. I am going to get dangerous and try to add it to the script myself, I'll post back here with any progress. Thanks for all the help!

fi

if [ $read = "Cancel" ]; then
exit 0

I got bored and "accidentally" got the conversion part in there myself *stares in shock* :shock: , this is how mine turned out:

#!/bin/sh
read=`gmessage -center "Stream Recorder" -buttons Record,Cancel -print`

if [ $read = "Record" ]; then
mplayer 'http://citadelcc-karn-fm.wm.llnwd.net/citadelcc_KARN_FM?MSWMExt=.asf' -dumpstream -dumpfile ~/Documents/recording.asf &
mplayer 'http://citadelcc-karn-fm.wm.llnwd.net/citadelcc_KARN_FM?MSWMExt=.asf' &
gmessage -center "Stop Recorder" -buttons Stop;killall mplayer; ffmpeg -i /home/halstan/Documents/recording.asf -f mp3 /home/halstan/Music/KARNHD.mp3; gmplayer /home/halstan/Music/KARNHD.mp3
fi

if [ $read = "Cancel" ]; then
exit 0
fiSo pretty much the same. All I added was the part to play the stream as it records, that's more convenient as I will know when to stop it. (i.e. I will not blindly start and stop the recording, cutting radio sentences in two)

BTW Yep, the gmplayer worked great. Just as a question, is there a way to add another pane to the script? I want it to show a box "Where do you want to save this file?" before it starts recording. Is that possible?

P.S. Just a laugh, but :

Applicant: "I'm the one you want. On my last job, every time something when wrong, they said I was responsible." :lolflag:
