Learning gtkDialog (pmenu project)

Message

Continuing work on an updated pmenu...

pmenu-3.0.0.pet

The pet for 3.0.0 REQUIRES /usr/bin/switch2 from gtk-theme-switch-i386.pet.

Using the image preview technique developed by zigbert you can now see the icons for each menu item.
(Page 28 of the Gtkdialog - tips thread)

To edit the .desktop files the program now calls "defaulttexteditor" instead of "geany" directly.

I've also included the "Exec" path information as suggested by big_bass.

Next update will include a confirmation dialog for the Full, Empty, and Delete Item buttons. I think these are drastic actions and should require a confirmation.

I am also still planning the ability to directly edit the .desktop files from the program in the future, as long as it doesn't slow it down too much.

Also playing around with the idea of sorting the items by category instead of alphabetically...

afishe2000,

That looks quite nice. You may find that changing the occurrences of "EDITPATH = X" to "EDITPATH=X" (remove the spaces on either side of the "=" sign) would fix your problems.

Cheers,

Hi afishe2000

I agree with seaside.. when defining a variable don't put spaces either side of the "=". Different story when testing the condition of that variable of course.

What I normally do, for most actions (depends on complexity) inside the gtkdialog, is define a function before the gtkdialog.

Here is an extremely simple example I made some time ago:

Code: Select all

#!/bin/bash
#funtion to find and move clock skin
function INSTALL(){
	
	CLOCK_PATH=`grep '*.png' $CLOCKSKIN | cut -d '/' -f2`
	mv $CLOCKSKIN /usr/local/pwidgets/widgets/clock_skins/$CLOCK_PATH 2>/dev/null
}
export -f INSTALL

export CLOCK="
<window title=\"Clockskin Installer\">
 <vbox>
  <text><label>\"Drag a clockskin to the box\"</label></text>
   <entry>
    <variable>CLOCKSKIN</variable>
    <action>echo $CLOCKSKIN</action>
   </entry>
  <hbox>
   <button>
    <input file stock=\"gtk-ok\"></input>
    <label>\"OK\"</label>
    <action>INSTALL</action>
    <action>EXIT:ok</action>
   </button>
  </hbox>
 </vbox>
</window>
"
gtkdialog3 -p CLOCK
unset CLOCK

In this way, much more complex actions can be used.

Cheers

Environment variables do not seem to work for some reason - at least I've never been able to get them to work.

Here is the lazy solution: disable the edit button for removed items.

Also, checkout LxShortcut for editing .desktop files. http://sourceforge.net/projects/lxde/files/

Thanks to all,

That's exactly it. I've been beating my head against the wall trying to get environment variables to work, and they just don't...

Doing all this work on my EeePC 901 running puppeee, thanks for such a great distribution.

Jeff

jemimah · #6 Post by **jemimah** » Tue 20 Jul 2010, 13:55

Cool. If you make any further improvements let me know as I'm going to put the new version into Puppeee.

If you're looking for a second project, it would be good to combine the Xorg Scaling Wizard, and the Xorg Panning Wizard into one wizard as discussed here: http://pupweb.org/cgi-bin/yabb2/YaBB.pl?num=1276937129. There's a lot of potential for usability improvements.

afishe2000 · #7 Post by **afishe2000** » Tue 20 Jul 2010, 14:16

In the middle of re-reading the gtkdialog-tips thread.

In gtkdialog global variables are really constants.

The only way to pass variables is through a file.

Example:

Code: Select all

#!/bin/sh 

add() { 
  N=$(cat /tmp/number) 
  let N=N+1 
  echo $N 
  echo $N >/tmp/number 
} 

export -f add 
echo 0>/tmp/number 

export MAIN_DIALOG=' 
<vbox width-request="160"> 
	<text visible="true"><variable>TEXT</variable>
		<input>add</input></text> 
	<button>
		<label>Reset</label>
   <	action>refresh:TEXT</action> 
	</button>
	<button>
		<label>Reset</label> 
		<action>echo -1>/tmp/number</action>
		<action>refresh:TEXT</action>
	</button>  
	<button cancel></button> 
</vbox> 
' 

gtkdialog3 -c -p MAIN_DIALOG 
unset -f add 
unset MAIN_DIALOG

Lots to learn...

Basic problem solved, you can now edit from either table.

I'll continue to work with it. I'd like to have a integrated editor.

I would also like the right table deselected if the left is selected and vice versa.

Odd thing with the IF statement:
- Tried \$switch_Position instead of \$(cat /tmp/switch) - didn't work
- Tried [ \$(cat /tmp/switch) ] instead of [ \$(cat /tmp/switch) = true ] - didn't work

Still lots to learn...

Continuing work and adding extra capabilities.

I've edited the first post to include a current screen shot and a download to the current program.

Jeff

jemimah · #10 Post by **jemimah** » Thu 22 Jul 2010, 23:31

Personally, I think the startup item editor should be a separate program from pmenu. Otherwise I'm confused what to call it on the menu.

Looking good though. It would be great to be able to use the program to add new startup items.

afishe2000 · #11 Post by **afishe2000** » Fri 23 Jul 2010, 00:42

jemimah,

Easy to do, was brainstorming but separating makes much more sense.

I have a list of things that I modify to make puppeee look and work like I want it to. I'm just programming to make it easier to make all those modifications.

I'm always looking for hints and FAQs to make my computers work better for me.

Thanks again,

Jeff

Program is moving along nicely...

I updated the first post with a new screen shot and a .pet file of the work done so far.

Currently when you click on a Menu Item it brings up the data from the .desktop file.

I've read just about every google return for gtkdialog pixmap, the gtkdialog-tips like 10 times, and tried everything under the sun but just can't get the icons file to dynamically load into a pixmap with the rest of the .desktop data...

Any help or suggestions would be very much appreciated.

Thanks,

afishe2000,

Are you using "table"? Somewhere in the back of my mind is the idea that "tree" is necessary for pixmaps.

Hope that's it.

afishe2000,

I now see that you were not trying to put icons in the table, but next to the "Icon:" entry.

Updated the first post to pmenu-2.0.1.

Importing the icons into the edit area is killing me so integrated editing is still not complete.

You can view the .desktop properties and still edit the file using geany.

I've added the ability to run the selected program from within pmenu so you can get a better idea about the program then just the properties.

I also added the ability to delete the .desktop file if you find broken or duplicate links.

Still working on this project slowly...

afishe2000 · #16 Post by **afishe2000** » Sun 01 Aug 2010, 15:11

Oops,

Updated the first post to pmenu-2.0.2.

Had some of the button icons backwards.

afishe2000 · #17 Post by **afishe2000** » Sun 01 Aug 2010, 16:02

As I mentioned, the more I learn the less I seem to know.

I'm using to following code to try to have the pixmap change from speaker on image to the speaker off image by pushing the corresponding button.

The popup button then would open a new dialog and show that same image.

Obviously it isn't working as I'd envisioned.

Everyone has been so helpful, I feel like I just keep running into the wall every time I turn the corner...

afishe2000,

You might be able to do something with "flip-flops" (see section 10 of the Gtkdialog Tips below)
http://murga-linux.com/puppy/viewtopic.php?t=38608

Perhaps something where the image is made invisible -
<button visible="false"> and is toggled on and off.

Cheers,

Personally, I think the startup item editor should be a separate program from pmenu. Otherwise I'm confused what to call it on the menu.

well I did a chainsaw hack of afishe2000's pmenu2
I removed only the desktop editor and made it a stand alone app called
desktop_view_edit

so nothing gets touched in pmenu

*I didnt "package" it since I use TXZ format and this way anyone could test it
add the icon and desktop of your choice

@Hey afishe2000 great coding !
