0 | 0 | I am trying to create a legend of sorts using ObjectListView in Python.
I am able to accomplish this, using wx.PaintDC, DrawText, and DrawRectangle in wxPython, but it doesn't look very good because it is all free hand.

0 | 0 | I have a PyGTK GUI that has a gtk.Table.
Pressing one button will generate a PNG file.
I can show the PNG file in the GUI by adding it somewhere in the table and calling the main window's show_all method again.
Is there a better way? What if I want to show more than one PNG file at a time? | true | 6,126,044 | 1.2 | 0 | 0 | 0 | You can use a combination of gtk.Image, gtk.HBox (or VBox), and maybe gtk.ScrolledWindow if you plan on showing a lot of images. Just create a new gtk.Image, set the image using set_from_file, then call pack_end on the box to display it. | 0 | 173 | 0 | 1 | 2011-05-25T14:28:00.000 | python,gtk,png,pygtk | In PyGTK, what's a good way of displaying an image in a GUI? | 0 | 1 | 1 | 6,127,034 | 1 |
