I attach picturebrowser v0.4.

Massive internal changes.

The whole treeclass was cleaned up, and is easier to use.
I think it now has reached the "final" structure, so the method names will not change in future.
I just might add some more, or enhance some. what might require more parameters.

Old code:

I seperated the code to display the pictures in a own class now.
So it can easily embedded in own programs.
The class even manages to download pictures, that are dropped on the viewer (it uses wget).

I attach the source of a seperate small example application, that is described here:
http://www.murga-linux.com/puppy/viewtopic.php?p=302769#302769

As no tree is included, this example is extremely short Smile

The source for the picturebrowser is not adapted yet.

there was a bug in the load_picture() method in the pictureview class.
There 3 methods were called with a leading "picview.", so it did not work, if your instance of the class had a different name.

Uploaded 0.1b.

I updated the pictureviewer class, it can display PDF files now.

On Windows, you also need:

here is a small interface for Mplayer.
The GIT version no longer supports an own grafical interface as far as I see.

So I hacked together this simple "playbar" , it allows to pause or switch fullscreen.
The cursor keys work too, to jump forward/backward.

In jwm, the playbar is covered in fullscreen mode, hit "f" to turn of fullscreen again.

The playbar has no fileselector, so you must pass a movie as commandline argument, or add the "genie-mplayer" script with full path as run-action to rox-filer (set the correct path in that script, too).

In the current state, it is not really recommended for average users, I just post it as small coding example.
Compiled in Puppy 412.

the Genie mplayer did not compile in Puppy 4.12, I added some changes, so now it works.

Can anyone play here?

I like developing in Python (Windows refugee) and am wondering if I should have a go at Genie.

I'm very fond of the Python syntax and style which makes me think Genie is the more logical choice for me rather than Vala for example.

I can't really find a huge amount of info - Barry's page with the examples is about all. Just wondering how to go about diving into Genie.

Regards
Caleb

there are not many Genie examples.

But once you wrote some small programs, using our examples as template, you will find a meanwhile quite huge collection of other examples: those from Vala.

A genie program has a simpler syntax.
So it is pretty easy, to "translate" vala code to genie.

This is especially valid for Gtk based examples.
Both languages use external libraries, and their call are almost identical.

Good to know.
I will try to jump in when I can.

I'm currently swamped with Perl coding commitments for work - but I'll keep an eye on this for personal programming projects.

Great to see it can compile to Windows executable as well if the need arrives. With a windows executable will there be any dependencies or are they all built into the binary?

Hi to all , Guys

I need help.
I have puppy 4.20 and devx_420.sfs installed.
I usually program in win c# and I would like to try vala in puppy. So I have download these packages from a deb repository:

valac_0.7.2-1_i386.deb
libvala0_0.7.2-1_i386.deb
vala-utils_0.3.4-1_i386.deb
libcairo2_1.4.14-1_i386.deb
.. because I wanted to try the last version with last fixed bugs.
.. converted to pet and installed

and gtksourceview-2.0.2-i486.pet from this thread

and valide-0.4-1-i686-svn-2009-03-27.pet from this site : http://dotpups.de/puppy4/dotpups/Programming/Vala/

Next step i compile by hand the hello.vala pgm example, and all gone well

so i tried to create a new project in valaide and I have got these errors:

1. when I try to create a new project :
valide_project_manager_copy_template: assertion `path != NULL' failed

2. so i create a project by hand copying from glade1.vide in this thread and than open the project and tried to compile. but I have got this error:

PCRE library is compiled without UTF8 properties support.

Coul any one help me to understand what's wrog !

thanks

gpnet,
Please use this gtksourceview, the other one works erratic:
http://dotpups.de/puppy4/dotpups/Programming/Vala/gtksourceview-2.4.2.pet

I also attach the pcre-libraries I use in newyearspup.
Maybe those work for you.

Caleb,
no, the libs are not built into the binary.

There are 2 ways to deliver them:
1.) the user installs vala, a 10 MB download.
2.) you add the required libs in the same folder, where your binary is located.

I made a 5 MB (12 MB extracted) example package including required Wiindows libs:
http://www.murga-linux.com/puppy/viewtopic.php?t=40193
It is a pet, so easy to install, then it can be run with Wine.

Hi Mu,

Thanks for replay,

No, I can't use the gtksourceview 2.4.2 with valaide because if I do that (i tried ) I lost syntax Highlight ( almost in vala ). So I had to come back to previous version.

Thank you for the pcre libraries , I presume I have to replace the older one?

And what about the creation of a new project :assertion `path != NULL' failed
have you any suggestion?.

Also I notice that to work with vala / glade would be necessary the 3.6.x version because with this version you can save the xml UI in proper way for Gtk.Builder("xxxxx");
Have you any news about a new release or could I install it from deb packages ?.

Tanks a lot.
