This entry finally works. Somewhat 
. I mean it’s kind a buggy still. But it’s good enough for an alpha.
Look how much logic is in that little widget there:
def text(outlayer, win, name, x, y, width, height, set_text="", parse=False, fill=True,
editable=True, multiline=False , linebreak=False, centered=False):
# This function will handle all the text writting in the software.
# I'm not sure about how parsing going to work for script files later.
# But if it's currently works, means that I already implemented it into
# the program.
# Making the layer
surface = cairo.ImageSurface(cairo.FORMAT_ARGB32, width, height)
layer = cairo.Context(surface)
layer.select_font_face("Monospace", cairo.FONT_SLANT_NORMAL, cairo.FONT_WEIGHT_NORMAL)
layer.set_font_size(20)
# Some challenges that it will have is how to correctly store data about
# the text in the system. I think we can use the win.text variable to store
# directories of the data.
if name not in win.text:
# I need to get something done before I can pu scroll in.
scrollname = name
while scrollname in win.scroll:
scrollname = scrollname+"_text"
win.text[name] = {
"text" :set_text, # Actuall text you are editing.
"cursor":[len(str(set_text)),len(str(set_text))], # Cursor
"insert":False, # Whether the insert mode is on
"scroll":scrollname # If multiline. The pointer for the scroll value.
}

# Now I want to give a preview of the text it self. BUT. I need to be sure
