python - Creating a pygtk text field that only accepts number -

-

does know how create text field using pygtk accepts number. using glade build ui.

cheers,

i wouldn't know way simple switching settings, guess need handle via signals, 1 way connect changed signal , filter out that's not number.

simple approach(untested should work):

class numberentry(gtk.entry):     def __init__(self):         gtk.entry.__init__(self)         self.connect('changed', self.on_changed)      def on_changed(self, *args):         text = self.get_text().strip()         self.set_text(''.join([i in text if in '0123456789']))

if want formatted numbers of course go more fancy regex or else, determine characters should stay inside entry.

edit
since may not want create entry in python i'm going show simple way "numbify" existing one.

    def numbify(widget):         def filter_numbers(entry, *args):             text = entry.get_text().strip()             entry.set_text(''.join([i in text if in '0123456789']))          widget.connect('changed', filter_numbers)      # use gtk.builder rather glade, you'll need change format of .glade file in glade accordingly     builder = gtk.builder()     builder.add_from_file('yourprogram.glade')     entry = builder.get_object('yourentry')      numbify(entry)

javascript - Enclosure Memory Copies -

-
function myclass() { //lots , lots of vars , code here. this.bar = function() { //do numerous enclosed myclass vars } this.foo = function() { alert('hello'); //don't enclosed variables. } } each instance of myclass gets own copy of bar , foo, why prototyped methods use less memory. however, know more memory use of inner methods. it seems obvious me (1) below must true. agree? not distinct myclass instances have own distinct copies of bar, must have own distinct copies of myclass enclosure. (or else how bar method keep myclass variables straight on per instance basis?) now (2) question i'm after. since inner foo method doesn't use in myclass enclosure natural qustion is: javascript smart enough not keep myclass enclosure in memory use of foo? this depend entirely on implementation not language. naive implementations keep far more around others. answer true e.g. v8 (chrome's js engine) may not true spider...

-
example preg_replace('/\{[a-za-z.,\(\)0-9]+\}/', 'replaced', 'lorem ipsum dolor sit {tag1({tag2()})}, consectetur adipiscing elit.'); the result: lorem ipsum dolor sit {tag1(replaced)}, consectetur adipiscing elit. question as can see "tag2" has been replaced, want replace "tag1" know how can this? (in cases might this: {tag1({tag2({tag3()})})}) , on.) btw using preg_replace_callback, easier show preg_replace here site can test code: http://www.spaweditor.com/scripts/regex/index.php you need add curly braces character set. here's pattern used: /\{[a-za-z.,\(\)\{\}0-9]+\}/ and here result: "lorem ipsum dolor sit replaced, consectetur adipiscing elit."
