Oop's, a new test, StatusIcon:

Code: Select all

[indent=4]

/* Build with valac --pkg gtk+-2.0 yourfile.gs */

uses
    Gtk

init
    Gtk.init (ref args)
    var test = new StatusIconTest ()

    Gtk.main ()

class StatusIconTest : Window

    trayicon : StatusIcon
    menu : Menu

    init
        title = "StatusIcon"
        window_position = WindowPosition.CENTER
        set_resizable(false)
        destroy += exit_app
        var label = new Label("Look the house in your taskbar !!!")
        var hbox = new HBox (false, 0)
        hbox.pack_start (label, false, true, 0)
        add (hbox)

        /* Create tray icon */
        trayicon = new StatusIcon.from_stock(STOCK_HOME)
        trayicon.set_tooltip_text ("Hello, i'm a tooltip !")

        about.run()
        about.hide()

    def private exit_app ()
        Gtk.main_quit()

I don't know what to test now ! if someone have an idea ...

Hi,

For all persons interested, I created a small sdk of my genie test !

Nicolas.

[BarryK]

Hi all,

This is a new version with "line number" and "syntax highlighting" support !!!

You need the new gtksourceview to make compile !

Please test it !
Nicolas.

Nicolas,
Yes, I now have syntax highlighting!

When I open a file from the commandline, for example:
# simpletexteditor demo.htm

It opens at the end of the file. Can this be fixed?


Starting the editor in a terminal, without specifying any file on the commandline, I see this warning:

Code: Select all

** (simpletexteditor:2615): CRITICAL **: text_file_viewer_open_file: assertion `filename != NULL' failed
Unable to delete temp file, anyway it's not important !

...does that matter?

Note, I'm running my latest Woof-built "413", based on Puppy 412 with upgrades, GTK 2.14.7.

Hi Barry,

I have the same, can you try this:
Delete this line: text_view.scroll_to_mark (buf.get_insert (), 0.25, false, 0.0, 0.0)
Rebuild and test !

I ask you because I updated vala (version 0.7.4) and I can't compile the texteditor anymore.

Code: Select all

texteditor.gs:567.61-567.67: error: Argument 3: Cannot convert from `ulong' to `int'
                FileUtils.get_contents (filename, out text, out len)

Re-Hi Barry,

Ok i found a solution.
Under the function:

Code: Select all

 def open_file (filename : string) 

Add this:

Code: Select all

 go_to_line(1)

Before the line:

Code: Select all

 status_bar.push(0, "You are editing: " + filename) 

See you,
Nicolas.

Hi all,
This is a new version of sdk.

25 examples and 3 complete app !

See you,
Nicolas.

Ah, I've just realised why I can't compile it, my system has gtk 2.14.7.
Is it possible to not be reliant on gtk >= 2.16.x?

You can try with the attached patch

[BarryK]

Nicolas,
I inserted the line as you instructed above, it doesn't fix it. I now have two bugs to report with the simple text editor:

1
Chose to exit editor, file was changed, a dialog came up:
"The file is unregistered, do you want to save it?"
...clicking No or Yes buttons, nothing happens.

2.
Open a file on commandline, window displays end of file. The recommended fix
inserting go_to_line(1) did not work. The insertion point is at the beginning of the file, but it initially displays the end of the file.


...if you can fix these, I propose to replace Leafpad in Puppy. I would also like to rename the simple text editor as "NicEdit" if that's ok with you.

Nicolas,

A problem, I cannot get ValIDE to compile:

I love NicEdit, see my post, and a problem with syntax highlighting:

Hi everyoine, i need a little help with a problem:

i have downloaded the GieneExamples by MU, after looking at the picturebrowseri decided to make some changes to to it (i just translate some buttons labels to spanish) after that i compiled it (with the compile button in the valide program) and everything was fine. After that i run the program, clicked on one folder on the tree and the program crashes with a "segmentation fault"

i have downloaded all from http://dotpups.de/puppy4/dotpups/Programming/Vala/

reinstalled lots of times, but nothing seems to work.

i have also tried to compile the GenieExamples program, with the same results: when i click a folder on the tree, the program crashes with seg. fault

i'm using puppy 4.00, and i have installed the following packages:

libgee-0.1.5.pet
libgee_DEV-0.1.5.pet
vala-0.7.2-i486.pet
valide-0.4-1-i686-svn-2009-03-27-and-gedit.pet
gtksourceview-2.4.2.pet
ORBit2-2.14.7-i686.pet
GConf-2.18.0.1-i686.pet


now i'm gonna try to compile from source and see what happens, but if someone can help me it would be very nice.


greetings.

Nicolas,

in Newyearspup I had to replace in the file "wscript" 3 times "atleast_version='2.16.0'" to: "atleast_version='2.14.0'", then it compiled.

I also got the crash then.
So I ran:
gdb nicedit
run

Then when it crashed:
backtrace
(to finally exit, type "quit").

The backtrace showed:
(gdb) backtrace
#0 0xb7e3196d in gtk_print_context_get_height ()

So I replaced line 1054 for a test:

Code: Select all

        //height : double = context.get_height()
        var height = 1000

After compiling and running again, I get:
0xb7d61809 in gtk_print_operation_set_n_pages () from /usr/lib/libgtk-x11-2.0.so.0
(gdb) backtrace
#0 0xb7d61809 in gtk_print_operation_set_n_pages () from /usr/lib/libgtk-x11-2.0.so.0

So I comment line 1064:

Code: Select all

        //op.set_n_pages(numPages)

Now I get:
Program received signal SIGSEGV, Segmentation fault.
0xb7d7f9cd in gtk_print_context_get_width () from /usr/lib/libgtk-x11-2.0.so.0

With this method, you can find out, which function crashes your program.
I cannot tell you, why these functions crash, as I never used them before.
But I hope, this helps you, to find the errors.

Samedog, I will try to reproduce your errors tomorrow.
I actually had no time for coding as intended, sorry for the delay.

Mark

[samedog]

thanks for your answer MU, by the way, i have upgraded to puppy 4.2.1 and still getting the segmentation fault, now i'm gonna try to compile from sources..and see what happens

Nicolas,
I'm going to change the name of your text editor to 'NicoEdit' as I was informed that there is already a commercial javascript editor named NicEdit.

I'm downloading your latest "NicoEdit" right now, will test it.
