问题 Important note : I'm using PyGObject to get access to the GTK widgets, not PyGTK . That's what makes this question different from similar ones: PyGTK: How do I make an image automatically scale to fit it's parent widget? Scale an image in GTK I want to make a very simple app that displays a label, an image and a button, all stacked on top of each other. The app should be running in fullscreen mode. When I attempted it, I've run into a problem. My image is of very high resolution, so when I

问题 My vision of the program: icon in tray, left click on icon opens a window with shutdown, reboot, etc. buttons. The new Gnome specification advises to use notifications instead. StatusIcon >! (Deprecated since version 3.14: Use notifications) Unfortunately, I didn't find how Notify.Notification can be displayed in the tray. The only thing that I found is AppIndicator3.Indicator, but its constructor can only take a Gtk.Menu, which is unsuitable. Which classes may I use? 回答1: I had used

问题 I'm actually working on a relatively complex GTK+2 application. My application obviously have a main window; then I need to open a new "independent" Window. I need to place the "flying" window in a * precise position* of the screen, exactly at the vertices of a widget (a DrawingArea). I need to place the new window in a precise position of the screen, exactly at the vertices of a widget (a gtk.DrawingArea). So I thought the following algorithm: I get vertex coordinates of the DrawingArea

问题 I'm working in a app with Gtk+2 and i need to implement a File treeview. the actual code it's: public FileTree() { store = new TreeStore(2,typeof(string),typeof(string)); this.change_dir( "/dir/path" ); set_model( store ); // File icon var pixbuf = new Gtk.CellRendererPixbuf(); var column = new Gtk.TreeViewColumn(); column.set_title(""); column.pack_start(pixbuf, false); column.add_attribute(pixbuf,"stock-id",0); column.set_alignment(1.0f); append_column (column); // File name Gtk

问题 I would like to add content to the pages of an Assistant window (GtkAssistant) in Glade. When I add a new assistant, no children appear under the GtkAssistant. Further I cannot select (or delete or change) the contents of the 3 default pages Glade produces -- I can only select the assistant itself. So, I try increasing the number of pages to 5 and then adding a widget to one of the new pages. It gives me the error message: "Widgets of type Assistant need placeholders to add children." Is this

问题 As any GTK project grows, GTK applications tend to be bundled with gresources to separate out code and UI design. This is very useful because UI/UX designers don't need to know code in order to... well design and ultimately contribute their skills and effort to the project. Not only designers but programmers too benefit a lot! Because code becomes heavily "logic or problem solving" instead of maintaining both UI and logic code together in one single file. However, to compile our GResource we

问题 I have a working program in python 2.7 that I am trying to convert to python 3.3. The working version is: #!/usr/bin/python2 import gtk.gdk import sys def PixelAt(x, y): w = gtk.gdk.get_default_root_window() pb = gtk.gdk.Pixbuf(gtk.gdk.COLORSPACE_RGB, False, 8, 1, 1) cm = w.get_colormap() pb = pb.get_from_drawable(w, cm, x, y, 0, 0, 1, 1) return pb.pixel_array[0][0] print(PixelAt(int(sys.argv[1]), int(sys.argv[2]))) The partly converted one is: #!/usr/bin/python3 from gi.repository import Gtk
