find a file on your system something like /root/.config/gtk-2.0/gtkfilechooser.ini
In it there is a setting `ShowHidden=false`. Change it to true.


Yes. That's what i was looking for. Thanks very much. I didn't even realize a config file was created!

To explain how it is possible to press the Enter key to
input the data to your program I have written a little script.

Just look at the script and run it and you will
understand the method that Zigbert explains on the first page.

Decompress to obtain script.

To show the selection of a folder by the two possible
methods Xdialog or gtkdialog. Compare each method
and decide which is best.

I wrote a simple script to compress a folder that the user selects.

The big difference is that Xdialog adds a slash at end of path.

I wanted to show how it is possible to choose a folder and
enter data in another field at the same time.

To see the final application I created go HERE

Using the most recent version of gtkdialog this is possible
(See image) When the folder is choosen the time
to compress is calculated (using a simple estimate based on size)
and then displayed in box underneath.

Compare this with the old method where a
refresh button had to be clicked to make a calculation.

I've included two scripts to show the two methods.
Re quires the most recent version of gtkdialog


refresh button version...

'mpg321 /dir/file' to play a audio-file.
If you use 'ffmpeg -i "/dir/file" -f au - | aplay -D plughw' it will play mp3, ogg, wma, flac, wav, ... without including more dependencies.
...


I tried -a 0:0, then -a :hw, then -a 'hw:0,0', then -a 0:hw:0, but now, i know the right word!
Finally, i've found the solution! Thanks!

-=Quirky Linux -1.40=-
mpg321 -a :plughw -o alsa /folder/file.mp3

OR:

mpg321 -a 0,0:plughw -o alsa /folder/file.mp3

To share sound card which has no hardware sound mixing:

aoss mpg321 -o alsa /folder/file.mp3

To Zigbert

On the first page -----> scrolling text example

Is this line correct? Just one quote sign?

Code:
  while : ; do echo -e "x\n 100; sleep 0.5; done
