Embed a spreadsheet/table in a PyGTK application?

问题

In my application, we want to present the user with a typical spreadsheet/table (OO.O/Excel-style), and then pull out the values and do something with them internally.

Is there a preexisting widget for PyGTK that does this? The PyGTK FAQ mentions GtkGrid, but the link is dead and I can't find a tarball anywhere.

回答1:

GtkGrid is deprecated in favor of the more powerful and more customizable GtkTreeView.

It can display trees and lists. To make it work like a table, you must define a ListStore where it will take the data from, and TreeViewColumns for each column you want to show, with CellRenderers to define how to show the column. This separation of data and render allows you to render other controls on the cell, like text boxes or images.

GtkTreeView is very flexible, but it seems complex at first because of the many options. To help with that, there's the relevant section in the PyGTK tutorial (although you should read it entirely, not just this section).

For completeness, here's an example code and a screenshot of it running in my system:

#!/usr/bin/env python

import pygtk
pygtk.require('2.0')
import gtk

class TreeViewColumnExample(object):

    # close the window and quit
    def delete_event(self, widget, event, data=None):
        gtk.main_quit()
        return False

    def __init__(self):
        # Create a new window
        self.window = gtk.Window(gtk.WINDOW_TOPLEVEL)
        self.window.set_title("TreeViewColumn Example")
        self.window.connect("delete_event", self.delete_event)

        # create a liststore with one string column to use as the model
        self.liststore = gtk.ListStore(str, str, str, 'gboolean')

        # create the TreeView using liststore
        self.treeview = gtk.TreeView(self.liststore)

        # create the TreeViewColumns to display the data
        self.tvcolumn = gtk.TreeViewColumn('Pixbuf and Text')
        self.tvcolumn1 = gtk.TreeViewColumn('Text Only')

        # add a row with text and a stock item - color strings for
        # the background
        self.liststore.append(['Open', gtk.STOCK_OPEN, 'Open a File', True])
        self.liststore.append(['New', gtk.STOCK_NEW, 'New File', True])
        self.liststore.append(['Print', gtk.STOCK_PRINT, 'Print File', False])

        # add columns to treeview
        self.treeview.append_column(self.tvcolumn)
        self.treeview.append_column(self.tvcolumn1)

        # create a CellRenderers to render the data
        self.cellpb = gtk.CellRendererPixbuf()
        self.cell = gtk.CellRendererText()
        self.cell1 = gtk.CellRendererText()

        # set background color property
        self.cellpb.set_property('cell-background', 'yellow')
        self.cell.set_property('cell-background', 'cyan')
        self.cell1.set_property('cell-background', 'pink')


        # add the cells to the columns - 2 in the first
        self.tvcolumn.pack_start(self.cellpb, False)
        self.tvcolumn.pack_start(self.cell, True)
        self.tvcolumn1.pack_start(self.cell1, True)

        self.tvcolumn.set_attributes(self.cellpb, stock_id=1)
        self.tvcolumn.set_attributes(self.cell, text=0)
        self.tvcolumn1.set_attributes(self.cell1, text=2,
                                      cell_background_set=3)

        # make treeview searchable
        self.treeview.set_search_column(0)

        # Allow sorting on the column
        self.tvcolumn.set_sort_column_id(0)

        # Allow drag and drop reordering of rows
        self.treeview.set_reorderable(True)

        self.window.add(self.treeview)

        self.window.show_all()

def main():
    gtk.main()

if __name__ == "__main__":
    tvcexample = TreeViewColumnExample()
    main()

It's perhaps a little more manual than, for instance, a GridView in .Net, but the Tree View widget will do what you need and much more. See PyGtk TreeView

You might consider embedding a web page viewer - you can do a lot with that: http://blog.mypapit.net/2009/09/pymoembed-web-browser-in-python-gtk-application.html
