Re: [pygtk] Problem with gtk.TextView in Windows, but not in Linux
Tim, I tried using "monospace" and it looks like it works fine. If it works as well in Linux that's what I'll use. Thanks!

Courier is an old bitmap font which is probably why it doesn't work properly, Courier New is the truetype version. You could also use the font name "monospace" which will default to a useful monospaced font.

Re: [pygtk] Problem with gtk.TextView in Windows, but not in Linux
Dieter, Good catch! It seems to be an issue with the Courier font in Windows. If I replace the line that specifies the font with one saying "Sans 12" everything is fine and I'm guessing that the mysterious disappearing cursor problem might be improved too. I had reasons for wanting to use a Courier font, but for Windows users of my program this is a useful workaround. Thanks much!

Re: [pygtk] Problem with gtk.TextView in Windows, but not in Linux
Dieter, I tried replacing all my Python and PyGTK files with older versions and that didn't help. What's odd is that I CAN split a line into two lines with the Enter key; I just can't create a blank line. What I think is that something I've installed may be interfering with the TextView. I'm going to try installing on another computer running Windows and see if the same thing happens. Most of my computers at home are running Linux, so I may end up trying at work. It is a great help to know that my program seems to work on Windows for other people, so I thank everyone who tried it.

Quoting "James Simmons" : I tried it and it didn't work. I also tried replacing the GTK bundle with the older one, and the program would not accept it. I verified that the TextBuffer actually does contain the newlines. It's just that the TextView ignores them. Even if you have a text file that has newlines in there to begin with, visible in Notepad so I know the line endings are correct, the TextView seems to just compress them out. I verified with print statements that the lines are being added to the buffer. Strange. Everything works when I load an empty text file into your program. Could you post the example image and text file the ocr package produced you use for testing?

Re: [pygtk] Problem with gtk.TextView in Windows, but not in Linux
Stephen, I too notice the cursor issue, but it comes and goes. Sometimes it's there and sometimes it just disappears on you. It does this in both Linux and Windows. Thanks for giving me your versions. These are the ones I'm using on Windows XP Pro: Python version 2.7.1 GTK+version 2.22.0 pyGTK version 2.22.0 gobject version 2.26.0 cairo version 1.8.10 I tried replacing the GTK+ bundle with 2.16.6 but apparently when you do that you need to downgrade the other stuff too. I'll try using older versions of everything and see what happens.

Re: [pygtk] Problem with gtk.TextView in Windows, but not in Linux
Hi James, Tried your program on windows and I could NOT see the problem you are describing, to me it worked as expected. > This program works flawlessly in Linux, but not in Windows. In > Windows everything works *except* when you hit the Enter key in the > TextView. It does not insert a new line. And here you are talking about a new line of text and not a newline character[1] as a line ending - something that I think is confusing many of the other replies. For me it did insert a new line, .. onto the text view. Once closing the app, .. I can see the new line in the file also. It did not matter were the line was inserted at the end of the text or somewhere in the middle. So unless you have changed the source to a working copy since posting this message, I'm not sure why you are seeing the behaviour you are seeing.. Just to be sure you were not talking about line endings as the problem, I also checked the line endings on the text file, .. under windows they were . I then did a second test and started with a file that had linux line endings, modified it in your program, and checked it after and ALL line endings had been converted to windows format line endings. The only thing I found annoying was that there was no cursor in the text view, so you had to use mouse to find the correct insert point, and wait till the first character came out to check it was were you expected. > I'm using the very latest Python plus the very latest PyGTK, Cairo, > PyGObject, and GTK+ bundle. > These are the versions when I tested it: Windows XP Home (in a virtual machine) Python version 2.6.6 GTK+version 2.16.6 pyGTK version 2.16.0 gobject version 2.20.0 cairo version 1.8.6 On Windows 7 64bit OS (32 bit python and gtk) Python version 2.6.6 GTK+version 2.22.0 pyGTK version 2.22.0 gobject version 2.26.0 cairo version 1.10.8 Steve [1] - newline = on windows, compared to on linux. ___ pygtk mailing list pygtk@daa.com.au http://www.daa.com.au/mailman/listinfo/pygtk Read the PyGTK FAQ: http://faq.pygtk.org/

Dieter, I tried it and it didn't work. I also tried replacing the GTK bundle with the older one, and the program would not accept it. I verified that the TextBuffer actually does contain the newlines. It's just that the TextView ignores them. Even if you have a text file that has newlines in there to begin with, visible in Notepad so I know the line endings are correct, the TextView seems to just compress them out. I verified with print statements that the lines are being added to the buffer.

Re: [pygtk] Problem with gtk.TextView in Windows, but not in Linux
Linux and windows use different types of line breaks. Linux uses \n and Windows \r\n (And mac \r I believe). So I think you should add an extra \r when your program is run on Windows and the user hits enter. I don't know why Textview doesn't do that itself. I'm a pygtk beginner myself...

The program has a left pane and a right pane. The left pane is a gtk.TextView and the right pane is a gtk.Image.
