PostPosted: Wed 03 Aug 2011, 21:47    Post subject: where to find window icons  
I can't seem to get a window icon to appear on my apps. Can some tell me where the icon image files needs to be located to work on a dialog as below.

<window title=\"NASViewer\" icon-name=\"NASviewer16.xpm\">

I've tried the full path as well and that didn't work.

Thanks!

If you click on ROX, the house icon on your desktop and then on Puppy Reference, there will be a number of icon directory links shown.
You can put your icon in any of them although I would suggest /usr/share/mini-icons.
Or you can create a link to it.

When one is writing a gtkdialog script, there seems to be no reference one can refer to as to words that are reserved for gtkdialog.
A list of those words would be nice so one knows not to use them as variables or other areas where they might conflict with reserved words.

Good idea or bad?

You create a shell script to construct a Gtkdialog XML-like structure which is stored within a shell variable that's passed to the gtkdialog binary. The variable names that Gtkdialog exports to the shell are those that you've instructed it to use e.g. <variable>LABEL1</variable> (widgets containing multiple items also export additional variables with an "_ALL" suffix on exit). Recently I found within an example a Gtkdialog exported shell variable named BUTTON which holds the mouse button id (if applicable) that triggered an action, but I'm not aware of anything else (I searched the code for "setenv" and "putenv"). Therefore other than MAIN_DIALOG, the <variable> names that you store within the XML and BUTTON that Gtkdialog may export, what else is there to conflict with? If you give me an example I can assist you with it.

Unfortunately this lack of documentation is not unique to gtkdialog, it seems
to be pretty common in the Linux world.
A very big stumbling block for newbies like myself.

Dave.

  • Widget Reference - it's not completely populated but it's a good start.
  • GTK+ 2 Reference Manual for the GtkEntry Widget - the <entry> widget within Gtkdialog (the GTK+ read/write properties are the Gtkdialog tag attributes).
  • Use the GTK+ 2 Reference Manual to find other properties for other widgets or use Gtkdialog's Widget Reference which already includes the links.
  • There's a very useful Widget Construction section with links to GTK+ widget properties (tag attributes) within the main post of the Gtkdialog Development thread.
  • The same post includes a list of comprehensive examples for the newly added or extended widgets.
  • You can browse the original but recently updated examples within the repository or you can checkout the source code; examples included.
  • There's a Documentation section on the project page.

If there's something that you think is lacking in documentation then let me know and I'll address the issue Smile

Thunor

Issue 8 within the issue tracker (zigberts issues) has a request for "supporting <item stock=gtk-open>coloumn1|coloumn2</item> from an input file". I came across an example named 09.03-tree_icon_columns that supports <input stock_column="0"> which accepts a stock_id as the first column (icon_column="0" also works for theme icons). Therefore the ability to input stock or theme icons into tree rows from a file already exists and you can do it like this:
Code:
#!/bin/sh

GTKDIALOG=gtkdialog

function inputfile() {
   echo "gtk-open | | gtk-open | 2
   gtk-about | | gtk-about | 2
   gtk-add | | gtk-add | 2
   gtk-apply | | gtk-apply | 2
   gtk-bold | | gtk-bold | 2
   gtk-cancel | | gtk-cancel | 2
   gtk-cdrom | | gtk-cdrom | 2
   gtk-clear | | gtk-clear | 2
   gtk-close | | gtk-close | 2
   gtk-color-picker | | gtk-color-picker | 2
   gtk-convert | | gtk-convert | 2 " > inputfile
   ifs="$IFS"
   IFS=
   echo $(<inputfile)
   IFS="$ifs"
}; export -f inputfile

export MAIN_DIALOG='
<vbox>
   <frame Stock icons from file via input command>
      <tree>
         <variable>TREE1</variable>
         <label>0 | 1 | 2</label>
         <height>300</height><width>250</width>
         <input stock_column="0">inputfile</input>
      </tree>
   </frame>
   <button ok></button>
</vbox>
'

$GTKDIALOG --program=MAIN_DIALOG

Jwm will automatically look for an icon with the _same_ name as your program in its icon path (name.png or name.xpm) ... no 16, case must match etc...just make a symlink without the description of size etc... most wm's do the same.

thunor,
Speaking of examples, what is it with an included example in gtkdialog/examples/09.12-tree-one-column

It is written with an incorrect path to gtkdialog and even though the executable property is set on it, it shows the same as a text file would and not an executable script.
It looks like it is supposed to populate itself with files from the working directory, but does not.
Is it a "fix it yourself" example?
I am just curious as to what it is supposed to display.

Also!! Thank you for the references of documentation for gtkdialog.
It all helps as does this offering by seaside.

Fixed now, and 09.00-tree as well.

They use "ls" to build rows using theme icons but the commands weren't working properly and the icons didn't exist.

Thunor

Is there any way to add a filter to gtk-open "fileselect" for specific filetypes?

Jpeps,

I have not seen any way, although there is the "complete" function, but I don't think it's available.

You could perhaps call Zenity/Yad or maybe Xdialog (not sure about Xdialog) with a "yad --file-selection --file-filter" option.

Regards,
s
EDIT: I suppose you could also do a "ls *.jpg" action to a tmpfile and then pick from there.

I'm sure I must be doing something wrong, but when importing a file to the "list" widget and selecting an item, it wasn't linking with the widget "variable"

Not image as far as I know but any background colour is possible..

it's a case of running a unique gtk+ theme for that app.

Code:
echo "style \"slideshow\"

{
   bg[NORMAL]      = \"$COLOUR\"
}

class \"*\" style \"slideshow\"" > /tmp/gtkrc

export GTK2_RC_FILES=/tmp/gtkrc:/root/.gtkrc-2.0


Slideshow was a silly little app I wrote ages ago, but that code should give you the gist of it, obviously the COLOUR variable must be set, it can be any defined colour or in the #000000 format

TCL-TK works nicely. I got sick of sloppy work-arounds.

What about gnocl? Because it would be much nicer to have GTK dialogues etc, as this is the standard for everything in Puppy.
