I am trying to get to grips with treeviews in pygtk/gtk and am stuck on setting the alignment of the columns.
No matter what I try I cannot change the alignment[IMG]http://ubuntuforums.org/images/smilies/eusa_wall.gif[/IMG]
Here is the code I found on the web which I am using to change different lines to see the effect and thus learn how they work. However I added the line self.cell1.set_property('alignment', pango.ALIGN_CENTER) and it makes no difference. I have tried right align too with no joy!
Can anyone help me please?
def __init__(self):
# Create a new window
self.window = gtk.Window(gtk.WINDOW_TOPLEVEL)
self.window.set_title("TreeViewColumn Example")
self.window.set_size_request(400, 200)
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.cell.set_property('cell-background', 'cyan')
self.cell1.set_property('cell-background', 'pink')
self.cell1.set_property('alignment', pango.ALIGN_CENTER)
# 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)
# set the cell attributes to the appropriate liststore column
# GTK+ 2.0 doesn't support the "stock_id" property
if gtk.gtk_version[1] < 2:
self.tvcolumn.set_cell_data_func(self.cellpb, self.make_pb)
else:
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()
