pygtk

问题 I started writing a small application in Python with GTK+ as my widget toolkit. Recently I decided to do some memory optimization and noticed that a most of PyGTK objects I create never gets released by garbage collector. This number keeps growing even if I open a window and properly destroy it afterward. Can someone point me in the right direction on how to create and handle GTK+ objects from Python. Am not using Glade or anything like that. Also I noticed that creating window like this:

问题 I've got a gtk.Expander object, containing in its label a gtk.HBox, which packed a gtk.Image and a gtk.Label. I want to launch a Webbrowser when the HBox is right-clicked. Here is my code: def launchBrowser(widget, host, event): print event print host if event.type == gtk.gdk.BUTTON_PRESS: if event.button == 3: webbrowser.open(host, 1) print "right click" def addServer(self, loginfo): main_expand = gtk.Expander() main_led = gtk.Image() if int(loginfo["main"]) == 0: main_led.set_from_stock(gtk

问题 Is it possible to set the position of an image using pygtk? import pygtk import gtk class Example: self.window = gtk.Window(gtk.WINDOW_TOPLEVEL) self.image = gtk.Image() self.image.set_from_file("example.png") # Position goes here (it should, shouldn't it?) self.window.add(self.image) self.image.show() self.window.fullscreen() self.window.show_all() 回答1: GTK lays widgets out based on relative alignments and padding, not absolute pixel positions. Instances of gtk.Image have properties xalign,

问题 Although I am not new to Python, this is my first attempt at using Glade to design the interface. My Python file looks like this: import gobject import gtk import gtk.glade class prefs_dialog: def __init__ (self): # Initialize the dialog self.window = gtk.glade.XML("file.glade").get_widget("prefs_dialog") self.window.show() pd = prefs_dialog() gtk.main() And the "file.glade" file looks like this: <?xml version="1.0"?> <glade-interface> <!-- interface-requires gtk+ 2.16 --> <!-- interface

问题 So what I'm trying to do is to join something in the form of os.path.join('C:\path\to\folder', 'filename'). **edit : Actual code is : filename = 'creepy_%s.pcl' % identifier file = open(os.path.join(self.cache_dir, filename), 'w') where self.cache_dir is read from a file using configobj (returns string) and in the particular case is '\Documents and Settings\Administrator\creepy\cache' The first part is returned from a configuration file, using configobj. The second is a concatenation of 2

问题 In below picture you can see the 3 parent child window. actually I made one code which will show all child according to parent. that is showing correctly but i want username & password column editable for database parent only(like as 3rd window). other should not be editable. In my case all child of parent is editable. here is my code #!/usr/bin/env python import pygtk pygtk.require('2.0') import gtk, gobject import os import cairo, gio, pango, pangocairo, atk class BasicTreeViewExample: #

问题 Please see this code example: import gtk class MenuBox(gtk.EventBox): def __init__(self): super(MenuBox, self).__init__() self.set_visible_window(False) self.connect('enter-notify-event', self._on_mouse_enter) self.connect('leave-notify-event', self._on_mouse_leave) btn = gtk.Button('x') btn.set_border_width(12) self.add(btn) def _on_mouse_enter(self, wid, event): print '_on_mouse_enter' def _on_mouse_leave(self, *args): print '_on_mouse_leave' def main(): win = gtk.Window() win.connect(

问题 I wrote these two lines in a Python program and they worked fine : subprocess.Popen("./prog infile outfile >/dev/null", cwd="/path/to/prog", stdout=subprocess.PIPE, shell=True) output = subprocess.Popen("prog1 infile1 2>/dev/null", stdout=subprocess.PIPE, shell=True).stdout.read() However these two lines of code do not work correctly in my PyGTK application. I invoke these lines from a handler called on the "row-activated" signal of a TreeView widget. Neither does prog write the outfile , nor

问题 I just managed to get py2exe work on a Windows Virtual Machine but stumbled on another problem which I didn't have right after I installed GTK, Pango, Gobject etc. on that machine: When I launch a Python Script the window appears but it immediately stops responding. This happens too if I open a python interpreter and type: import gtk w = gtk.Window() w.show() I'm not allowed to post any images yet, but here's the link to a screenshot: http://i.stack.imgur.com/3RJ0n.png This is a problem for

问题 I have the following script clip-test.py : #!/usr/bin/python import gtk gtk.Clipboard().set_text("exciting clipboard contents") gtk.Clipboard().set_can_store(None) # not sure if these last two lines are useful gtk.Clipboard().store() When I run this like so: python clip-test.py it doesn't work. The clipboard is unchanged. We can elucidate the issue by running it in interactive mode and not letting the process finish: python -i clip-test.py Before leaving interactive mode, try pasting
