However, if GridFlow X loses focus, by switching focus to another widget in a pile or column for example, GridFlow X shows only the first cells of the GridFlow rather than those around the former focus cell. A minimal example can be found at http://pastebin.com/6X0vNMAq . Run the script, scroll down so that Button 0 is no longer showing and hit 'tab'. Focus will switch to the second GridFlow, but the first GridFlow now show button 0 again as though it had never scrolled. I would expect the GridFlow to retain its 'position' even without focus, like ListBox does. Is this a strange expectation or is GridFlow's behavior strange? To change this behavior, would GridFlow require calculate_visible() like ListBox? Thank you.

I am building a status gui composed of Text widgets in a Listbox, traversed by a SimpleListWalker. The problem I'm having is that when I update one of the Text widgets with 'varname.set_text("example"), the text string "example" appears in the appropriate Text widget, but it also appears to add a carriage return, meaning the entire display below the updated Text widget shifts down one line. How do I prevent this from happening? How can I simply overwrite what was in the Text widget in the first place without a new line showing up? BTW, I am using Urwid1.0.1 and Python 2.4.

I'm happy to announce the containers changes I've been working on for a few months have now landed in the default/master branch. This is a long post but there's lots of good stuff here. If you see a problem with the API or its implementation now's the time to let me know! CONTENTS 1. New Container API 2. Container and Decoration Widget Improvements 3. List Walker API V2 4. New Simple List Walker and Monitored List Types 1.

Backwards compatibility is still maintained for the old container-specific ways of accessing and modifying contents, but the new API is now the preferred way of modifying and traversing containers. cont.focus is a read-only property that returns the widget in focus for this container.

In doing so, I encountered a problem using urwid's ListBox when setting a focus explicitely. The following code generates a display with 3x5 checkboxes. The focus is explicitely set on the second entry in the third row. When running this code in a terminal which is large enough to hold the focus without scrolling the list, the focus is set to the first entry in the third row instead of the second. When the terminal is small enough not to hold the focus without scrolling, the focus is set properly. I could trace the problem back to the render method of the ListBox, which explicitely alters the focus of the contained Columns object. (See the second code snippet and the corresponding output). Is this a bug in the ListBox or am I doing something wrong when setting the focus? Any help would be appreciated! Best regards.

The latter has now caused problems for a number of people. A really common request is to just want to indent something by a few characters, but to do that safely you need to do something like: urwid.Padding(my_thing, width=('relative', 100), left=4) My preference is to change the width default to ('relative', 100) for the next Urwid release, and add a warning for people using Padding without specifying a width in the next bugfix release 1.0.2. The 'pack' option only really works for Text widgets, and only makes a difference to the appearance (as compared to ('relative', 100) when the text alignment is different than than the padding alignment). So I believe the potential for breaking existing programs is low.

I've already submitted some minor patches to make the raw_display.Screen() object more friendly to subclassing, now I'd like to get the Terminal() patched as well. The issue is that Terminal assumes the self.master attribute is a file descriptor and it will inline calls to os.read()/os.write() on this attribute. If the attribute is anything other than a file descriptor, it will raise an exception and die. This makes it convoluted to have the master attribute as a ProcessProtocol, which is the simplest solution for a Twisted application subclassing and implementing the Terminal. The best solution, from my POV, is to have all access to the the self.master attribute wrapped in method calls which can be overwritten. There are two options, either make the Terminal widget know how to do I/O on self.master, or make self.master an object. That is, either: # original code: os.wri</pre> the grugq 2011-11-27T00:46:32 http://comments.gmane.org/gmane.comp.lib.urwid/1147 <pre>Hello Ian and community! I'm new to urwid; trying to compose an application that needs to show lots (LOTS!) of progress bars at the same time. Could be some 10 to 20, of them, depending on external factors. I've been digging into urwid for a couple of days already but with a limited success. So I decided to ask for some help: (1) Would anyone suggest a widget class (or configuration of classes) that would let progress bars order themselves let's say 5 or 6 per row (all should be the same width). (A snippet of code would be highly appreciated.) (2) I would like that composite to have a border built using pseudo-graphical characters on a utf-8 console. Any suggestions for a suitable decorator (or how to build one) ? Thank you in advance!

But this input box must share vertical space with other widgets, so I don't want it to expand to display everything inside the input box. Is there a commonly-accepted way to do this? For example, if the screen shows: widget1 widget2 biginput1 biginput2 can I tell biginput1 and 2 to both constrain themselves to maximum 5 rows? It seems the documentation refers to "maxrow", but I can't find an example of how to do this. Is this even the right way to do it, and if so how?

There's a new example showing how to serve Urwid interfaces to many users simultaneously over ssh with Twisted. There are new classes to help with creating dynamic tree views of anything you have that's tree-like. There are new widgets for working with pop-ups so you can now have all the menu bars, drop-downs and combo-boxes you can write. The old requirement to sprinkle draw_screen() calls around your callbacks is gone. Urwid now updates the screen automatically after everything else is done.
