I'm trying to add to the "recently used" files list from Python 3 on Ubuntu. I am able to successfully read the recently used file list like this: from gi.repository import Gtk recent_mgr = Gtk.RecentManager.get_default() for item in recent_mgr.get_items(): print(item.get_uri()) This prints out the same list of files I see when I look at "Recent" in Nautilus, or look at the "Recently Used" place in the file dialog of apps like GIMP. However, when I tried adding an item like this (where /home/laurence/foo/bar.txt is an existing text file)... recent_mgr.add_item('file:///home/laurence/foo/bar

My current project uses a Gtk.TreeView to display the contents of a ListView with four fields per row, two strings, an int and a boolean . I'm trying to implement drag and drop rearrangement of rows in the TreeView. I don't want simply to use TreeView.set_reorderable(True) for the built-in drag and drop because I want to have some control over the insertion and deletion of data from the model as well as to be able to implement undo/redo of drag and drop operations. I'm using Python 3.2 and PyGObject 3. The problem I'm now having is figuring out how in my drag_data_get method to set the

Is there any way to specify spacing between lines of text in multiline Gtk3 Label, as with CSS line-height property? This CSS property does not work and I can't google out anything else. user1150388 I found the solution using Pangoattribute on label <br>PangoAttrList *attr_list;</br> <br>PangoAttribute *attr;</br> <br> attr_list=pango_attr_list_new();</br> <br>attr=pango_attr_rise_new (20000);</br> <br>pango_attr_list_insert(attr_list,attr);</br> <br>gtk_label_set_attributes(GTK_LABEL(label),attr_list);</br> 来源： https://stackoverflow.com/questions/25139645/gtk3-label-line-spacing

I am trying to limit the amount of decimal places shown in a Gtk.CellRendererText. Currently a float number field is shown with 6 decimal places, but I would like to have just 1. This test code should work on Linux: #!/usr/bin/python3 from gi.repository import Gtk class MyWindow(Gtk.Window): def __init__(self): Gtk.Window.__init__(self, title="Hello World") self.set_default_size(200, 200) self.liststore = Gtk.ListStore(float) treeview = Gtk.TreeView(model=self.liststore) self.liststore.append([9.9]) self.liststore.append([1]) xrenderer = Gtk.CellRendererText() xrenderer.set_property("editable"

I have a tray icon with a popup menu. I am trying to set the background color of the menu items in this popup. I am able to set the text color but not the background color of the menu item. The background that appears is the default Ubuntu orange, and I can't override it. I've created a sample application that demonstrates this problem. Just copy-paste it into a .py file and it should run. from gi.repository import Gtk, Gdk import sys class TrayIcon: def __init__(self): self.statusicon = Gtk.StatusIcon() self.statusicon.set_from_stock(Gtk.STOCK_MEDIA_PLAY) self.statusicon.connect("popup-menu",

I have a font file /path/to/app/fonts/custom-font.ttf and I want to use it. How do you import a custom TTF for use in a GTK+3.0 app? from gi.repository import Gtk, Pango # ... lbl = Gtk.Label() lbl.modify_font(Pango.FontDescription("sans 48")) # lbl.modify_font(Pango.FontDescription("custom-font 48")) If you want to using it as a preview to your own app, install the font and uncomment the last line (provide the right name). If you want to use it as custom font for final release, i suggest you package with the font and make a script to install it. A little note, (in C), ".modify_font"

Using PyGTK, I used to be able to take a screenshot using gtk.gdk.pixbuf.get_from_drawable . I can't seem to figure out how to do that using PyGObject and GdkPixbuf. I've tried get_from_drawable and get_from_window but neither work in PyGObject. Thanks in advance. Use Gtk.OffscreenWindow : offscreen_window = Gtk.OffscreenWindow() offscreen_window.add(widget_that_needs_screenshotting) pixbuf = offscreen_window.get_pixbuf() 来源： https://stackoverflow.com/questions/14544500/how-do-i-take-a-screenshot-using-gdkpixbuf
