Description
-
A notebook contains a set of tabbed pages. At any one time only
one of these pages (the selected page) is visible, with the
other pages being hidden "beneath" it. Another page in the
notebook may be displayed by clicking on the tab attached to the
page. The tabs are displayed along the top edge.
Optionally, the notebook may be displayed without tabs. In this
case, another selection widget, such as Pmw.OptionMenu, may be used
to select the pages.
This megawidget is derived from Pmw.MegaArchetype (not Pmw.MegaWidget
like most other megawidgets), with the hull class being
tkinter.Canvas.
-
Options
-
Options for this megawidget and its base
classes are described below.
- arrownavigation
-
Initialisation option. If true and a tab button has the keyboard focus, then the Left and
Right arrow keys can be used to select the page before or after
the tab button with the focus. The default is 1.
- borderwidth
-
Initialisation option. The width of the border drawn around each tab and around the
selected page. The default is 2.
- createcommand
-
Specifies a function to call when a page is selected for the first
time. The function is called with a single argument, which is the
name of the selected page, and is called before the raisecommand
function. This allows the creation of the page contents to be
deferred until the page is first displayed. The default is None.
- lowercommand
-
Specifies a function to call when the selected page is replaced
with a new selected page. The function is called with a single
argument, which is the name of the previously selected page, and
is called before the createcommand or raisecommand functions. The default is None.
- pagemargin
-
Initialisation option. The margin (in pixels) around the selected page inside the
notebook's page border. The default is 4.
- raisecommand
-
Specifies a function to call when a new page is selected. The
function is called with a single argument, which is the name of
the selected page. The default is None.
- tabpos
-
Initialisation option. Specifies the location of the tabs. If 'n', tabs are created
for each page and positioned at the top of the notebook. If
None, no tabs are created, in which case another selection
widget can be used to select pages by calling the
selectpage()
method. The default is 'n'.
-
Components
-
Components created by this megawidget and its base
classes are described below.
- hull
-
This acts as the body for the megawidget. The contents of the
megawidget are created as canvas items and positioned in the
hull using the canvas coordinate system. By default, this component is a tkinter.Canvas.
-
Dynamic components
-
Page and tab components are created dynamically by the add()
and insert() methods. By default, the pages are of type
tkinter.Frame and are created with a component group of Page
and the tabs are of type tkinter.Button and are created with a
component group of Tab.
-
Methods
-
Only methods specific to this megawidget are described below.
For a description of its inherited methods, see the
manual for its base class
Pmw.MegaArchetype.
In addition, methods from the
tkinter.Canvas class
are forwarded by this megawidget to the
hull component.
- add(pageName, **kw)
-
Add a page at the end of the notebook. See the
insert() method
for full details.
- delete(*pageNames)
-
Delete the pages given by pageNames from the notebook. Each of
the pageNames may have any of the forms accepted by the
index() method.
If the currently selected page is deleted, then the next page, in
index order, is selected. If the end page is deleted, then the
previous page is selected.
- getcurselection()
-
Return the name of the currently selected page.
- index(index, forInsert = 0)
-
Return the numerical index of the page corresponding to index.
This may be specified in any of the following forms:
- name
- Specifies the page labelled name.
- number
- Specifies the page numerically, where 0 corresponds to
the first page.
- Pmw.END
- Specifies the last page.
- Pmw.SELECT
- Specifies the currently selected page.
If forInsert is true, Pmw.END returns the number of pages
rather than the index of the last page.
- insert(pageName, before = 0, **kw)
-
Add a page to the notebook as a component named pageName. The
page is added just before the page specified by before, which
may have any of the forms accepted by the
index() method. If
tabpos is not None, also create a tab as a component named
pageName-tab. Keyword arguments prefixed with page_ or
tab_ are passed to the respective constructors when creating the
page or tab. If the tab_text keyword argument is not given, the
text option of the tab defaults to pageName. If a page is
inserted into an empty notebook, the page is selected. To add a
page to the end of the notebook, use add(). The method returns
the pageName component widget.
- nextpage(pageIndex = None)
-
If pageIndex is None, then select the page after the
currently selected page. Otherwise select the page after
pageIndex, which may have any of the forms accepted by the
index() method.
- page(pageIndex)
-
Return the frame component widget of the page pageIndex, where
pageIndex may have any of the forms accepted by the
index()
method.
- pagenames()
-
Return a list of the names of the pages, in display order.
- previouspage(pageIndex = None)
-
If pageIndex is None, then select the page before the
currently selected page. Otherwise select the page before
pageIndex, which may have any of the forms accepted by the
index() method.
- recolorborders()
-
Change the color of the page and tab borders. This method is
required because the borders are created as canvas polygons and
hence do not respond to normal color changing techniques, such as
Pmw.Color.changecolor().
- selectpage(page)
-
Select page to be the currently selected page. The page will be
raised and the previous selected page will be lowered.
- setnaturalsize(pageNames = None)
-
Set the width and height of the notebook to be the maximum
requested width and height of the pages specified by pageNames.
If pageNames is None, the size of all pages are used to
determine the size of the notebook. Otherwise, pageNames must
be a list of page names whose sizes are to be used to determine
the size of the notebook. This method should be called after all
pages and their contents have been created. It calls
update_idletasks() so that the width and height of the pages can
be determined. This may cause the notebook to flash onto the
screen at the default size before resizing to the natural size.
- tab(pageIndex)
-
Return the tab component widget of the page pageIndex, where
pageIndex may have any of the forms accepted by the
index()
method. If tabpos is None, return None.

of the window (or part of the window) produced
by the following code.
class Demo:
def __init__(self, parent):
# Create and pack the NoteBook.
notebook = Pmw.NoteBook(parent)
notebook.pack(fill = 'both', expand = 1, padx = 10, pady = 10)
# Add the "Appearance" page to the notebook.
page = notebook.add('Appearance')
notebook.tab('Appearance').focus_set()
# Create the "Toolbar" contents of the page.
group = Pmw.Group(page, tag_text = 'Toolbar')
group.pack(fill = 'both', expand = 1, padx = 10, pady = 10)
b1 = tkinter.Checkbutton(group.interior(), text = 'Show toolbar')
b1.grid(row = 0, column = 0)
b2 = tkinter.Checkbutton(group.interior(), text = 'Toolbar tips')
b2.grid(row = 0, column = 1)
# Create the "Startup" contents of the page.
group = Pmw.Group(page, tag_text = 'Startup')
group.pack(fill = 'both', expand = 1, padx = 10, pady = 10)
home = Pmw.EntryField(group.interior(), labelpos = 'w',
label_text = 'Home page location:')
home.pack(fill = 'x', padx = 20, pady = 10)
# Add two more empty pages.
page = notebook.add('Helpers')
page = notebook.add('Images')
notebook.setnaturalsize()
