PostPosted: Mon 15 Feb 2010, 17:49    Post subject:  Gtkdialog examples from DEVX
Subject description: 07.02-list_actions		  
The example /usr/doc/gtkdialog/examples/07.02-list_actions script maxes out my processor when I run it and I have to kill it.
I tried making another button and putting the echo line there.
The program would then be ok until I clicked that button and again max out the processor.
So, any ideas as to why?

8-bit,

I don't have an answer to this question and I just wanted you to know that it happens when I try it also.

(I haven't used "list" and perhaps it's just as well) Very Happy

Thank you for the reply.
I also tried modifying the script by putting the echo line in an action call using the ok button to call it.
Then I tried adding xmessage without the echo.
There was no change as to processor maxing out and xmessage failed to display any output.
So I will keep playing round with it.
For now, I know not to use that form of list in any programs.

could you paste the example - I am not at a Puppy box to check it, but I can examine the script - it probably just needs a sleep 1 inserted somewhere in a loop. This one may have already been discussed in the gtkdialog tips thread.

You ask for the original example file and here it is 07.02-list_actions

Code:

#! /bin/bash

export MAIN_DIALOG='
  <vbox>
    <list>
      <variable>LIST</variable>
      <item>First item</item>
      <item>Second item</item>
      <item>Third item</item>
      <action>echo Chosen item is $LIST</action>
    </list>
    <hbox>
     <button ok></button>
     <button cancel></button>
    </hbox>
  </vbox>
'

gtkdialog3 --program=MAIN_DIALOG


I already tried moving the action line to be acted on by the OK button.

hmm - I would use a "combobox" for that instead of a list - I have a template for combobox in the how to section

http://www.murga-linux.com/puppy/viewtopic.php?t=45474


Code:
<combobox>
    <variable>COMBO1</variable>
    <item>item 1</item>
    <item>item 2</item>
</combobox>


then you will either need to eval MAIN_DIALOG after exit for the value of $COMBO1 or set up and action within the dialog window such as
Xdialog --infobox $COMBO1 0 0

I realize their are work arounds for the example program.
But.....
Why are there example programs in the /usr/share/doc/gtkdialog3/examples directory that just do not work.
Isn't an example supposed to work?

Also, can one find out where the example program is at fault and correct it?
Is it a matter of a debug option?
Everything seems fine till the <action>echo Chosen item is $LIST</action>
line is executed.
As to what is happening, that is to find out.
And the echo never takes place even when run from a terminal.

not really, but with the following, it does work and echos the choosen value...

Code:
#! /bin/bash

export MAIN_DIALOG='
  <vbox>
    <list>
      <variable>LIST</variable>
      <item>First item</item>
      <item>Second item</item>
      <item>Third item</item>
    </list>
  <hbox>
   <button ok></button>
   <button cancel></button>
  </hbox>
  </vbox>
'

I=$IFS; IFS=""
for STATEMENTS in  $(gtkdialog3 --program MAIN_DIALOG); do
  eval $STATEMENTS
done
IFS=$I

if [ "$EXIT" = "OK" ]; then
  echo "Chosen item is $LIST."
else
  echo "You pressed the Cancel button."
fi

aragon,

It appears to work because it exits to show $LIST.
But I have an option for you.
When creating a GUI, why have it use the echo command?
That entails running it from a terminal to see the output of the echo command.
Instead, just replace "echo" with "xmessage".
Then the output will be displayed in a GUI type message box.

sure, but i wanted to leave it as it has been in the example...

but usually this is to give parameter to an external comand.
