Whist MU astounds us with real programs
I am attempting to use Valide in Jaunty Pup with the devxx
First of all Valide is now more stable - hooray

I had to go back to basics
Valide seems to be changing
tabs to two indents (this is the default mode, which I will stick with
BUT can be changed in Edit / Preferences from the latest Valide)
Valide is much improved

So I place this on top of programs

I attach a next step.
This is a tree, that displays the folders on your computer, and the files in them.

This is far from being finished, but basically works.
I just upload it for people, who might need to look up the one or other command in the code.

The filebrowsing is not yet placed in the treeview class, so the main.gs looks prettty complex, you also could say "messy".
So do not use it as a template for an own program yet.
The trees now are attached to a project.glade, that also includes the 3 buttons.

Lobster,

yes, you can setup in "edit - preferences" the "Tab width".
If you prefer 4 , you can set it there.
I also use this setting now, as the code then is better readable.

I updated the filebrowser to v0.2, it now sorts the folders and files alphabetiically.

I have not cleaned up the classes yet, but it was challenging, to add some lines, that turn the filebrowser into a usable application.
So now it is a small pictureviewer Smile

I updated the source to v0.3.

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

Banshee (http://banshee-project.org/Main_Page) <-replace pmusic,
Beagle (http://beagle-project.org/Main_Page) <-replace pfind
F-spot (http://f-spot.org/Main_Page)
MonoDevelop (http://www.monodevelop.com/Main_Page)
Tomboy (http://www.gnome.org/projects/tomboy)

or maybe even some of the ones here
http://csharp-source.net/

(btw thanks for pointing me to http://mono-project.com/GtkSharp_TreeView_Tutorial)

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.

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 Crying or Very sad

Yes... devx seems broken.. I'll try in 412

MU · Posted: Sun 03 May 2009, 19:44 Post subject:

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 Crying or Very sad

that my spup devx is busted but that might be fixed by woof beta. Smile

Thanks for your help Mark.

EDIT: Laughing

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/Programming/Vala/Vala-for-Windows/libglade-libxml-comdialog32.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.
