Tasty stuff. :)
Here are Gtkdialog versions, but indeed, they're quite heavy, so on weaker CPUs there may be need to increase 'interval' value.

Thanks & Greetings!

Dear SFR,

Very nice. I had to increase the interval from:

Code: Select all

interval="60"
to

Code: Select all

interval="120"
in spiral_4.sh (line 1203) to get my old beater of a computer to respond. It now shows the animated SVG nicely. :)

With kind regards,
vovchik

script to explain comboboxtext widget

Script to explain comboboxtext widget

I wanted a simpler explanation for the comboboxtext widget
so I wrote this script to show a simple implementation.
Two different methods are shown. The first shows a menu
composed of 'items'. The second has the menu composed from
a list stored in a file on your hard drive.

to eliminate excessive disk writes you can use the ram based file systems on /dev/shm or /tmp for your temporary files ... just don't forget to remove them when you are done.

Hey Technosaurus

Yes, I'm using it ever since you told me about it in SelfCrypText thread.
And I prefer /dev/shm, because (AFAIK) /tmp might not be kept in RAM in case of full installs.

Hmm, windows can grow... Tested under JWM/IceWM.

Code: Select all

S=$(<$SIZE); S=$(($S+2)); echo $S > $SIZE
[ $S -ge 512 ] && exit

Hyperlinks

Posted: Tue 16 Apr 2013, 05:41
by DocSalvage
I'm working on an awk program that converts Zim pages to GtkDialogs for checklists and such so it needs to have functional hyperlinks.

I've learned that the Pango markup "<span><a>..." formats the hypertext just fine but taking action on the click is the problem. I've made it work by wrapping the GtkDialog <text> widget in its own <hbox> which is, in turn, wrapped in an <hbox > for the entire line of text. Conceptually, the code looks something like...

Code: Select all

<hbox>
  <hbox>
    <text>
      <label>"<span>non-link-text</span>"</label>
    </text>
  </hbox>
  <hbox>
    <text>
      <label>"<span><a href="...">link-text</a></span>"</label>
      <action signal="button-press-event">...</action>
    </text>
  </hbox>
  <hbox>
    <text>
      <label>"<span>non-link-text</span>"</label>
    </text>
  </hbox>
</hbox>
Very much a work in progress, but maybe this will help others trying to use hyperlinks.

One cuestion.

Why don't work this program, and how I can get work.

#! /bin/bash
export CHOOSER
export MAIN_DIALOG='
<vbox>
<chooser>
<height>500</height><width>600</width>
<variable>CHOOSER</variable>
</chooser>
<hbox>
<button help></button>
<button ok></button>
</hbox>
</vbox>
'
gtkdialog --program=MAIN_DIALOG
exec mplayer CHOOSER

I was searching everywhere and I can't see how choose one file and open with some application program, like this example or if I want open file by Menubar.

Thanks for any help.

Code: Select all

exec mplayer "$CHOOSER"

No work.

Thanks zigbert for answering but don't work.

The problem with the variable CHOOSER inside of GTKDIALOG is local variable, I not know how export variable outside of GTKDIALOG.

The only way I met is :

Code: Select all

#! /bin/bash
export MAIN_DIALOG='
<vbox>
  <chooser>
   <height>500</height><width>600</width>
   <variable>CHOOSER</variable>
  </chooser>
 <hbox>
   <button ok>
      <action>"echo $CHOOSER > /tmp/tmp"</action>
	  <action>exit:Exit</action>
   </button>
 </hbox>
</vbox>
'
gtkdialog --program=MAIN_DIALOG
A=$(cat /tmp/tmp)
echo "$A"
exec mplayer $A
But I think is not very elegant.

Anyway Thanks for you reply.

Making it a function works

Code: Select all

#! /bin/bash
CHOSEN(){
mplayer $CHOOSER
}
export -f  CHOSEN
export MAIN_DIALOG='
<vbox>
  <chooser>
   <height>500</height><width>600</width>
   <variable>CHOOSER</variable>
  </chooser>
 <hbox>
   <button ok>
	  <action>CHOSEN</action>
	  <action>exit:Exit</action>
   </button>
 </hbox>
</vbox>
'
gtkdialog --program=MAIN_DIALOG

Works...

Amazing Geoffrey! Works.

When call to the variable trough function works.

Have a problem when you try to choose mplayer file in other partition or hard drive.

Thanks for teaching this way

You can also do it this way-

Code: Select all

eval `gtkdialog --program=MAIN_DIALOG`


This runs the gtkdialog program between the backtics and then evaluates (sets the variables for further use)

Cheers,
s

Thanks seaside

Thanks seaside... works perfect.

I check it in the first program, and work perfect and I can open one mplayer file well, even if the file is in other partition or other hardrive.

So thanks for teaching this way too.

Good teachers in this Forum.

Multiple defaults in tree

Hello,

Does anyone know of a way set multiple defaults in the tree widget? I see a selected-row tag but that only sets a single default. Does anyone know of how to do this? Thanks in advance!

gtkdialog changing shell variable

Posted: Thu 06 Jun 2013, 19:25
by jmrichardson
Hello,

I have been trying to figure out how to change a bash variable value within gtkdialog. That is, I load a config file to set my variables within gtkdialog. However, i would like to change the variable value based on user input. When i change the value with an action, it doesn't change the value on exit (it stays the same). I think the action function is kicking off a sub shell, changig the variable there, then returning back to the main shell. If that is correct, any way to change the parent shell variable value without using files for storage?

Thanks,
John

I'm no expert but if 'export VARIABLE' doesn't work
then I use 'echo $VARIABLE > /path/to/file'

Then I reload in a new function or application.

VARIABLE=`cat /path/to/file`

or

read VARIABLE < /path/to/file

Hey guys,

is there any option to have checkboxes within a gtkdialog tree/list/table? I would like to select multiple items.

Input is optained from a textfile:
monitor1|true|option1
monitor2|false|option2
monitor3|true|option3
Output is written to a textfile.

Thanks & regards,
box579.

Hello !
I'm trying to create a GUI (GTK) and I need help.
I use the combobox option and I do not want the user could edit the items offered (so that he can choose only in the list of items proposed by the script).
Currently, my combobox like this:

Code: Select all

<vbox>
<text><label>Live Support</label></text>
<combobox width-request=\""$COMBOBOX_WIDTH"\" tooltip-text=\" Select the live support \">
<variable>CheckLiveSupport</variable>
$LIVE_SUPPORT_ITEMS
</combobox>
</vbox>
My question: is it possible to prevent the publishing of the items proposed by the combobox?

Cordialement,

Posted: Wed 31 Jul 2013, 09:34
by box579
Hi ASRI education,
to prevent users from editing your items use <comboboxtext> instead of <combobox>. See below, for specs read this:
http://code.google.com/p/gtkdialog/wiki/comboboxtext

Code: Select all

<vbox>
<text><label>Live Support</label></text>
<comboboxtext width-request=\""$COMBOBOX_WIDTH"\" tooltip-text=\" Select the live support \">
<variable>CheckLiveSupport</variable>
$LIVE_SUPPORT_ITEMS
</comboboxtext>
</vbox>
