how to keep the same format for text that has been read

[moroccanplaya]

hi i have i open a url using urllib.request. urlopen then store the source code by using url.read to a variable and i paste the source code into the tkinter text widget but how do you keep the same format ??

 
with urllib.request.urlopen(path) as url:
        sourcecode = url.read()
        global storecode
        storecode = sourcecode
        tkinter.messagebox.showinfo("sourcode copied:", path)
        Text.insert(tkinter.END,storecode) 
#i want the source  code to be kept in he same format

One way is to use readlines() and insert each line individually if newlines are not displaying properly. But we do not know what is wrong with the display you get, and we do not know what type of widget "Text" is. I would suggest that you take a look at the Pmw extension, especially the ScrolledText widget.

im using the standard tkinter.Text widget

i sorted it out with readlines() but im guessing the text widget is not wide enough and i need to add a horizontal scroll bar

is the scrolledtext widget better ?

Scrollbars are not that difficult. You just attach them to the xview or yview of the widget (an example for the Text widget is at http://effbot.org/zone/tkinter-scrollbar-patterns.htm), but why re-invent the wheel?

thanks i have the scroll bars on, but the size of the scroll bar is really small its not the same size as the tkinter text widget, i tried putting the scroll bar in a separate frame but that did not work, how do you set the length of the scroll bar is thee an option for it?

HTML was designed for data display with a focus on how it looks. It won't display the same in a Tkinter Text widget. Here's an example of a Tkinter Text widget with scrollbars that displays the contents of a text file:

import Tkinter
"""
Edit a file and save the text.
"""
 
textFont1 = ("Courier New", 16, "normal")
 
class ScrollbarX(Tkinter.Scrollbar):
    def set(self, low, high):
        if float(low) <= 0.0 and float(high) >= 1.0:
            self.grid_remove()
        else:
            self.grid()
        Tkinter.Scrollbar.set(self, low, high)
 
class App(Tkinter.Tk):
    def __init__(self, fn, fnout):
        Tkinter.Tk.__init__(self)
        self.title("Text Widget")
        self.fin = open(fn, 'r')
        self.fnout = fnout
        self.mainFrame = Tkinter.Frame(self)
        self.mainFrame.grid()
        self.exit = Tkinter.Button(self.mainFrame,
                                   text="Save and Exit",
                                   command=self.finish)
        self.exit.grid(row=0, column=0, sticky="ns")
 
        vscrollbar = ScrollbarX(self.mainFrame)
        vscrollbar.grid(row=1, column=1, sticky="ns")
        hscrollbar = ScrollbarX(self.mainFrame, orient=Tkinter.HORIZONTAL)
        hscrollbar.grid(row=2, column=0, sticky="ew")
 
        self.textWidget = Tkinter.Text(self.mainFrame,
                                       yscrollcommand=vscrollbar.set,
                                       xscrollcommand=hscrollbar.set,
                                       wrap=Tkinter.NONE,
                                       height=24,
                                       width=60,
                                       font=textFont1)
        self.textWidget.insert("1.0", self.fin.read())
        self.textWidget.grid(row=1, column=0, sticky="nsew")
 
        hscrollbar["command"] = self.textWidget.xview
        vscrollbar["command"] = self.textWidget.yview
 
    def finish(self):
        fout = open(self.fnout, 'w')
        fout.write(self.textWidget.get("1.0", "end"))
        fout.close()
        self.fin.close()
        self.quit()
 
if __name__ == "__main__":
    fn = "edit.txt"
    fnout = "editresult.txt"
    app = App(fn, fnout)
    app.mainloop()
    app.destroy()
