Hi,
I am writing a POV-RAY editor with Python using either QT or GTK as GUI
'wrapper'. ( I am still trying both )
* * * * PYGTK * * * *
I have downloaded PygtkScintilla-1.99.5.
There is a lexPOV.cxx file in the package, but I can not find any POV
keywords in any file ( there are about 150 POV keywords). Did i miss it,
and if not, how do I create one and include it for the library building ?
Anyway, I compiled pyscintilla and got a library file called 'scintilla.a'.
Now how do I link the scintilla.a library to this GTK script example :
8<--------------- snip ------------>8
import pygtk
pygtk.require('2.0')
import gtk
import scintilla
class GUI:
def __init__(self):
window = gtk.Window(gtk.WINDOW_TOPLEVEL)
window.set_title("Pyvon")
window.connect("destroy", lambda w:gtk.main_quit())
table = gtk.Table(10,10)
# Here we connect notifications as they are gtk signals as well
editor = scintilla.Scintilla()
#s.connect("CharAdded", char_added_notif)
window.add(table)
table.add(editor)
editor.show()
window.set_size_request(200, 300)
window.show_all()
def main():
gtk.main()
return 0
if __name__ == "__main__":
GUI()
main()
8<--------------- snip ------------>8
The same goes for QT :
* * * * PYQT * * * *
I have also downloaded qscintilla-1.62-gpl-1.5.1.
As for GTK, I also found the LexPOV.cpp file, with no POV keywords in it
and with no POV keywords in any of the file in the package.
The compilation builds then move the library libqscintilla.so to
/usr/lib/qt3/lib.
How do I link the newly built library to the folling qt script :
