Since vala shares a lot of syntax with C#, maybe these projects that use gtk# would be a good source of "inspiration"
Banshee (

Beagle (
http://beagle-project.org/Main_Page) <-replace pfind
F-spot (

MonoDevelop (

Tomboy (

or maybe even some of the ones here

I have completely restructured the pictureviewer.
main.gs is very short again.
You now have additional files like libglade.gs or filebrowser.gs.
They help to keep the code readable.
The tree related filebrowsing methods are now part of the treeclass.
So you do not have to mess around in that code, you simply just use the methods.
The class manages everything automatically.
Just for additional actions, filebrowser.gs is available.
Here you can for example explicitly force to update the file-list in the second tree, when a folder in the first tree was clicked.
I added several comments, so I hope, it is easy to use.
I might add more comments in future, and want to add more methods.
But in the urrent state, it is already a full working template for your own, file tree based programs.

Have you ever tried to compile Beagle? I have and it gets way blown out of size due to deps, Terrible program, I tried two+ weeks ago when I wanted a Pfind replacement, It looked nice and had great reports, but the size was the downfall, So then I tried Search Monkey and that was perfect 117kb pet and a perfect replacement with better features than Pfind and easy to configure.
Banshee is also nice but uses gstreamer, another large program, BMP is the best replacement for Pmusic thats made with 'C' and its uses winamp2 skins, its about 1/6 the size of banshee and also uses some xmms plugins also. I think the last time I compiled it on 4 series I had it down to 300kb pet.
The only way that banshee could ever make it in with gstreamer, is if we dropped gxine/xinelib for a gstreamer based mediaplayer. Then that could workout to be around the same size.
Good ideas just a bit too large for default puppy.
Hmmmm whats were we talking about here ???
sorry didn't mean to take you off topic.

Code: Select all
# valac hello.gs
error: Failed to execute child process "pkg-config" (No such file or directory)
error: Failed to execute child process "pkg-config" (No such file or directory)
error: Failed to execute child process "pkg-config" (No such file or directory)
Compilation failed: 3 error(s), 0 warning(s)
Genie noob here
This is the error I get when I try to compile "Hello World". Also a file is created called "hello.c", which seems perfectly useless!
What am I doing wrong??? (or what am I missing?)

you need devx_420.sfs, that has the compiler and pkgconfig.
------------------------------
I attach a new sourcepackage of the treeview.
It now is renamed to "Picturebrowser-0.2" to allow correct versioning with the Picturebrowser binary pet.
I added more methods to access the trees, you can look up how to use them in the example actions in filebrowser.gs.

strange then
I am running spup from woof I built... devx is loaded. I'll see if I can compile something else ... maybe my devx is broken
Yes... devx seems broken.. I'll try in 412

please type:
gcc
you should see:
gcc: no input files.
If you do not see it, devx is not loaded.
If you see it, you need pkg-config, this would mean it is missing for whatever reason.
I attach it, extract it in /usr/local/bin/.

Nah good. My devx is definitely broken. It says it is loaded on boot mgr, but the gcc command fails. In 412 now will install valide and load devx and try again!

Oooh.. I like the power! Nice. Working fine now. I was able to compile BK's examples... they look nice!
Bit sad
that my spup devx is busted but that might be fixed by woof beta.
Thanks for your help Mark.
EDIT:
My spup devx is fixed now! (it is my OS of choice ATM..
fast)

Picturebrowser 0.3.
A PET is available in the other thread:
http://www.murga-linux.com/puppy/viewtopic.php?t=41919
Here now is the
source, it includes a
Binary for Windows, and libglade.dll and libxml.dll.
To
run it in Windows:
Install:
http://valide.googlecode.com/files/vala-0.7.1.exe
It includes the required Gtk for Windows files.
Then unzip my archive somewhere, and click on Picturebrowser.exe.
To
compile, you also had to extract this:
http://dotpups.de/puppy4/dotpups/Progra ... alog32.zip
in: C:\vala-0.7.1
The refinements contain some new methods, and a general cleanup, so it is not only from advantage for windows.
In Windows, the new "autoscaling" is disabled (to fit the picture when you resize the window), because the threads do not work as expected (a known issue).
Update: Pet removed, see next messages for updated version.

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:
Code: Select all
treeclass1 = new treeclass()
treeclass1.mode = "filebrowser"
mytree1 = treeclass1.treeview()
treeclass1.column.set_title("Folders")
get_scrolledwindow("scrolledwindow1" ).add (mytree1)
var iter = treeclass2.get_first_iter(mytree2)
if treeclass2.store.iter_is_valid(iter)
treeclass2.select_iter(treeclass2, iter)
tree2_row_click()
New code:
Code: Select all
tree1 = new treeclass()
tree1.mode = "filebrowser"
tree1.init()
tree1.column.set_title("Folders")
var sw1 = (ScrolledWindow)get_widget("scrolledwindow1")
sw1.add(tree1.tree)
tree2.select_first_item()
tree2_row_click()
Please note, that also the
libglade.gs changed.
old:
Code: Select all
get_scrolledwindow("scrolledwindow1" ).add (mytree1)
This used a method, that had to be defined "by hand", like this:
Code: Select all
//-- HELPER method: this method returns a SCROLLEDWINDOW ! --
def get_scrolledwindow(name : string) : ScrolledWindow
b : Gtk.ScrolledWindow*
var w = xml.get_widget(name)
b = (ScrolledWindow) w
return b
This is no longer needed!
You only need these 2 lines:
Code: Select all
var sw1 = (ScrolledWindow) get_widget("scrolledwindow1")
sw1.add(tree1.tree)
I think this is one of the enhancements in Vala 0.7.1, if I remember well, it did not work in 0.5.7, so I had written those helper methods.
The Windows binary is included again.
The program
no longer uses "Threads" to scale a picture, but a method based on Gdk.Pixbuf.
This works faster, needs less resources (14% cpu-usage instead of 42%), and works in Linux and Windows.
And
bookmarks now also work with special characters in the filenames.
A PET for Puppy 4.12 follows later.

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/viewto ... 769#302769
As no tree is included, this example is extremely short
The source for the picture
browser 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.

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

Yes. This thread and Barrys page is about all there is in Genie (it is very new)
Valide and Genie are part of the devx for the latest Woof alphas.
Marks examples (go through this thread) and my paltry efforts are a good place to begin.
Genie is faster (being compiled) than Python and works on both Windows and Linux, creating standalone efficient code.
Mark is very supportive and Barry will be providing more work in the future
