Hi there,
I've got a tree control in Tkinter (using the ESRF Tree module) but I
can't get it to layout how I want it.
I'd like to have it so that it streches north/south (anchored to the top
and bottom), is of a fixed width and is anchored to the left hand side.
Here's my code (its derived from one of the examples from the ESRF web
site):
class MainWindow(Frame):
def __init__(self, master):
Frame.__init__(self, master)
self.document = # new DOM document
self.create_site_list()
def create_site_list(self):
self.list_model = ListModel(self.document)
# ListModel class returns the DOM outline as a simple Python data
structure
self.site_list = Tree.Tree(master=self,\
root_id="root",\
root_label="Site",\
get_contents_callback=self.get_list_item,\
# get_list_item uses the list_model to build list nodes
width=300)
self.site_list.grid(row=0, column=0, sticky=N+SW)
self.grid_rowconfigure(0, weight=1)
vsb = Scrollbar(self, orient=VERTICAL)
vsb.grid(row=0, column=1, sticky=NS)
self.site_list.configure(yscrollcommand=vsb.set)
vsb.configure(command=self.site_list.yview)
hsb = Scrollbar(self, orient=HORIZONTAL)
hsb.grid(row=1, column=0, sticky=EW+S)
self.site_list.configure(xscrollcommand=hsb.set)
hsb.configure(command=self.site_list.xview)
self.site_list.focus_set()
This code makes it centred in the east/west direction and a constant
height anchored to the top. I guess its the sticky values I need to play
with (?) but I can't find the right combination. I've given the code
with the ones that seem logically correct (to me!)
I expect this is probably quite trivial for someone who knows what
they're doing.
Any ideas?
Cheers,
Richard
