I wanted to test the above posted script but it gives me an gtkdialog error in gtkdialog3, gtidialog4 and gtkdialog5.

Which version is used for this script?

RSH

Hi RSH

Change all <variable export="false"> to <variable> and it'll work. I'll edit the script and remove them, they're not necessary.

Here's another top tip:

A text widget that has space-expand and space-fill set to true can be used as a spacer to push neighbouring widgets in certain directions.

Here the spacer text is "[]" so you can see it -- drag the window out and watch the button.

Code: Select all

#!/bin/sh

GTKDIALOG=gtkdialog

Spacer="[]"

MAIN_DIALOG='
<window title="Spacer Test" window-position="1">
	<vbox>
		<hbox>
			<button space-expand="false" space-fill="false">
				<label>This button will stay put</label>
				<input file stock="gtk-about"></input>
			</button>
			<text space-expand="true" space-fill="true">
				<label>"'$Spacer'"</label>
			</text>
		</hbox>
   </vbox>
</window>
'
export MAIN_DIALOG

case $1 in
   -d | --dump) echo "$MAIN_DIALOG" ;;
   *) $GTKDIALOG --program=MAIN_DIALOG ;;
esac

Hello Everyone,

I have a question, Has anyone done hyper-links in gtkdialog? If so how do you go about doing it.

What I would like to do is link from one program to another. Hit a word in one program to show the answer in another program.

Any help would be great thanks.

Cheers

Hit a word in one program to show the answer in another program

If you look at the code in puppy clock
you will see a button called 'World clock'

What it does is launch a second program.

You should check out how I wrote it.
When the button is first pressed, I check the version of
gtkdialog to make sure it is recent. Then I launch the second program.

Hi don570,

Will take a look and see if that is what I am looking for.

Cheers

EDIT: Hi don570 took a look not what I was looking for thanks, but I did remember that what I need is just a button to go to one to another program.

Just need to look at my code.

Cheers

Yes-No box with color

The Yes-No box in Xdialog is rather limited and the buttons
don't actually say 'Yes-No'

So I wrote a script to be a replacement to the Xdialog Yes-No box.
Here's a picture of the result.

Posted: **Fri 01 Feb 2013, 01:09**

continuing......

The script has been made as general as possible.
The script first creats a file in /root.
Then the Yes-No box appears and asks if you want to overwrite the file
with different text. 'Yes' results in overwriting of the file and the
window closes. You can check to see if the file has been overwritten.

When the user clicks 'No' an alternate action is possible.
It is of course possible to have the 'No' button have one action

EDIT: I changed the script from using an if statement to a case statement.
This clearly shows that three posibilities are possible

1) YES
2) NO
3) Click on corner close box will cause cancellation

Code: Select all

#!/bin/bash
# demonstrate  YES-NO box by don570

for P in gtkdialog4 gtkdialog3 gtkdialog; do
  GTKDIALOG=$(which $P) && break
done

# create a message for demonstration
echo  "first message" > /root/demonstrate-script.txt
TEXT="TEXT"  # demonstrate a substitution in text

#  put the warning-function near beginning of script

# purple color is #A900FF

Hi everyone,
I play a little thing about gtkdialog.
finally, I make a 'Limukstart'. with gtktheme wdz8.1 from here:
http://murga-linux.com/puppy/viewtopic. ... 393#671393
my startmenu tobe like this:

but i still have a problem. I can't use mouse scroll to scroll horizontally with gtkdialog unless my pointer over the hscrollbar. Is possible to scroll horizontal with mouse? How?
Thanks

Posted: **Sun 10 Feb 2013, 19:33**

I needed to change the following line:
*) gtkdialog4 --program=MAIN_DIALOG ;;

Notice I added the 4 after gtkdialog.

Also the file needs to be renamed by removing the .gz and made executable.

I didn't get a horizontal scroll bar as my screen is quite wide.

Posted: **Mon 11 Feb 2013, 04:33**

you are right, smokey01. thanks for your respond. I linked gtkdialog4 to gtkdialog. i reupload limukstart. i still can't scroll horizontally by mouse unless my pointer over the scroller. how?

The vscale widget supports action signals as described inn the references

Code: Select all

<action signal="type">activity</action>

Do anyone know what signal to use to run action WHILE moving slider?

Thanks
Sigmund

Posted: **Wed 13 Feb 2013, 13:11**

@Recobayu
I think there's a reason why it works this way - if you would had both horizontal AND vertical scrollbars at the same time, they would be scrolled simultaneously.
But horizontal scrolling works fine when I use touchpad ('Horizontal Edge Scroll' enabled).

@Zigbert
Is this what you mean? (see screenshot)
If so, leaving the default "value-changed" signal makes the given action executed properly while moving slider:

Code: Select all

echo '<window width-request="100" height-request="100"><vscale><variable>VAR</variable><action>echo $VAR</action></vscale></window>' | gtkdialog -s

HTH
Greetings!

Posted: **Wed 13 Feb 2013, 14:20**

SFR
I didn't have the 'value-changed' signal, but I had 'update-policy' defined.
- Now gone, and all works perfectly.

Thanks a lot!
Sigmund

There are too many hacked ways of getting the screen width,height and depth that make assumptions on a specific version of xrandr, xwininfo and their output format and the string manipulation tends to be pretty slow so I wrote a small and fast little helper in C here:
http://murga-linux.com/puppy/viewtopic. ... 996#685996
let me know if there are any other PITA parameters that are often needed and I can add them.

Hello Everyone,

I have a question about menus, Can one put a menu in as a input file?

I will have a very big menu very soon and would like to know if this is possible

Thanks for any help

I've discovered how to vary the width of the combobox at
the time of launch of the script.

A practical example is Bulldog finder, which widens up
when it is launched with a folder path as an argument $1

As an example I change the width based on whether my app has an
argument $1

Code: Select all

export WIDTH=240
[ -z "$1" ] && WIDTH=150]

then while building the combobox

Code: Select all

<combobox case-sensitive="false" value-in-list="true" width-request="'$WIDTH'">

Ah, the good old C64 times...
Does anyone remember DYCP (Different Y Character Position) effect?
It seems that Bash+Gtkdialog+SVG are powerful enough for that - here's an example (save it with .sh extension or else ROX will identify it as .svg file):

Code: Select all

#!/bin/bash

# DYCP example by SFR'2013

export SINUS=/dev/shm/sinus_table
[ -e $SINUS ] && rm $SINUS

# Create sinus table
for i in {0..63}; do
  RAD=`echo "$i*(3.14/32)" | bc -l`
  VAL=`echo "s($RAD) * 48 + 72" | bc -l`
  echo ${VAL/.*} >> $SINUS
done

dycp () {
SIN=( `cat $SINUS` )
echo '<svg width="256" height="128" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink">

<tspan x="10" y="'${SIN[0]}'">P</tspan>
<tspan x="30" y="'${SIN[2]}'">U</tspan>
<tspan x="50" y="'${SIN[4]}'">P</tspan>
<tspan x="70" y="'${SIN[6]}'">P</tspan>

<tspan x="210" y="'${SIN[20]}'">X</tspan>
<tspan x="230" y="'${SIN[22]}'">!</tspan>
</text>
</svg>' > /dev/shm/dycp_pic.svg

# Shift array right
echo ${SIN[63]} ${SIN[@]:0:63} > $SINUS
}
export -f dycp && dycp

export MAIN='
<window title="DYCP">
  <vbox>
    <pixmap>
      <variable>PICTURE</variable>
      <input file>/dev/shm/dycp_pic.svg</input>
    </pixmap>
    <button ok></button>
    <timer visible="false" milliseconds="true" interval="50">
      <action>dycp</action>
      <action>refresh:PICTURE</action>
    </timer>
  </vbox>
</window>
'

gtkdialog -cp MAIN

Of course it's rather pointless (and resource hungry), but personally I love such things!

The days of C64 were sure wonderful. The coding wasn't meant to be useful - only cool.

Thank you for sharing

Dear SFR,

That was an impressive bit of coding. I ported it to BaCon, with a few mods to reduce file reads/writes, and it works nicely. Thanks. Now to find a good use for this lovely routine

With kind regards,

Thanks guys!

I guess I also miss the old days, because computers' capabilities were very limited and there was a challenge - to crush those limits!
For instance - see how amazing gfx can still be created in ancient 320x256x32 (my_jaw_dropped).
[sorry for being a bit off-topic]

@Vovchik - Bacon version works OOTB on Slacko, no recompiling needed; nice work!
