Questions[anjuta](ubuntu)

So I want to use Anjuta and add a Theme. I use the GtkSourceView plugin as my editor. For some reason it doesn't allow me to define colors like with any any other editor but instead requires me to use a gtk theme.

I use Ubuntu Mate 20.04. I'm not sure why but gtksourceview-3.0 and gtksourceview-4 are both installed on my system.

To add a theme I tried a few things. I read someplace that you can make themes with a project called "oomox". I tried that, but it created a massive array of files and directories that didn't seem at all like what GtkSourceView uses, which is a single file. So I scrapped that.

I coped obsidian.xml (the closest to what I want my thing to look like) from /usr/share/gtksourceview-4/styles and edited it. I placed my new file into ~/.themes. That didn't work (it doesn't show up in the list when selecting a theme for Anjuta). I tried ~/.local/share/gtksourceview-4/styles and ~/.local/share/gtksourceview-3.0/styles and also ~/.local/share/gedit and ~/.local/share/gedit/styles (gedit is not installed though).

I am confused how I can add a simple style to this editor and why there isn't any information on that topic. I can imagine people wanting to customize their IDE all the time. Maybe I'm missing something obvious? I searched "adding theme to gtksourceview" and "adding theme to Anjuta". And all I found was how to add a theme to gedit (hence my attempts above) and how to switch the default themes.

Also I don't want to add my theme to the system install directory (/usr or /etc). Surely there is a way to add it for users (/home/<user>) only.

It would be really nice if there were some program I could use to edit my style and give me a preview of some code. (Like most other IDEs). If there is no such thing, then I'd be really nice to at least have a list of all the valid tags.

Edit: Just to test it, I put the new file in with the rest of them in /usr/share/gtksourceview-4/styles/ and 3.0 and 2. Neither soft links nor the file itself seemed to have an effect. I'm very confused. I doublechecked the file itself. All I did was add/delete some color tags and change colors about.

For clarity's sake here is the file.

Edit 2: I found these resources: https://developer.gnome.org/gtksourceview/stable/style-reference.html
But they don't detail which style names are valid. Or where to put the style file.

I have this boilerplate in a minimal Anjuta app that runs. I do not want to install pandas to the system python path so I am using Virtualenv. When I add import pandas as pd I get the following error message.

Not sure if this is Anjuta or Pandas related. I have googled for the error message but nothing instrumental. What do I do?

#!/home/USERNAME/my_app/bin/python3.6
import gi
gi.require_version('Gtk', '3.0') 
from gi.repository import Gtk, GdkPixbuf, Gdk
import os, sys, gi

...

from shutil import copyfile
import pandas as pd
...

And I get this.

without the import pandas as pd the program runs just fine...

The same import pandas as pd runs fine if used from a command line python script from the same directory and same virtualenv. Also it runs when called via subprocess.call() from Anjuta runmode.

I am on Ubuntu 18.04 and have installed Anjuta with apt, pandas with pip install pandas.

I know this question has been answered several times, I have tried each of them but still could not find the exact solution. I am starting to learn GTK + 3.0 with Glade User Interface. i know Glade will generate XML for the design and the same XML can be used in our c/cpp program. But to execute the program, one must have all the libraries installed or path must be set to the libraries in IDE's. I am using Anjuta IDE for developing this program whenever i tried to build the program I get the following error.

gtk/gtk.h: No such file or directory

Program code

#include <gtk/gtk.h>!
#include <glade/glade.h>

void
ok_button_clicked (GtkWidget *widget, gpointer user_data)
{
  printf ("Thanks for trying out my program.\n");
  gtk_main_quit ();
}

int main (int argc, char *argv[])
{
  GladeXML  *main_window;
  GtkWidget *widget;

  gtk_init (&argc, &argv);

  /* load the interface */
  main_window = glade_xml_new ("example-1.glade", NULL, NULL);

  /* connect the signals in the interface */

  /* Have the ok button call the ok_button_clicked callback */
  widget = glade_xml_get_widget (main_window, "OKButton");
  g_signal_connect (G_OBJECT (widget), "clicked",
                    G_CALLBACK (ok_button_clicked),
                    NULL);

  /* Have the delete event (window close) end the program */
  widget = glade_xml_get_widget (main_window, "MainWindow");
  g_signal_connect (G_OBJECT (widget), "delete_event",
                    G_CALLBACK (gtk_main_quit), NULL);

  /* start the event loop */
  gtk_main ();

  return 0;
}

Whenever I try to add Lib or External Lib, I am not able to add gtk/gtk.h file, The same file is already there in /usr/include/gtk-3.0/gtk/gtk.h and when I try to copy the same in libanjuta the same code still giving the same error, Any help will be highly appreciated friends, I am struggling lot to execute the program ..

Thanks Amul Bhatia
