| gnotebook {gWidgets} | R Documentation |
A notebook widget organizes different pages using tabs, allowing only one page to be shown at once. Clicking on the tab raises the associated page.
gnotebook(tab.pos = 3, closebuttons = FALSE, dontCloseThese = NULL, container = NULL, ..., toolkit = guiToolkit())
tab.pos |
Where to place tabs (1 bottom, 2 left side, 3 top, 4 right side |
closebuttons |
Is there a close button in the tab? |
dontCloseThese |
If closebuttons=TRUE this will make it
impossible to remove these tabs. Specified by tab number |

In what follows, it is useful to think of a notebook as a vector with named entries, each entry being a widget, the name being the tab label.
Notebooks have the following methods:
The svalue method returns the current page number. The
svalue<- method is used to set the page number.
New pages are added with the add method. The extra argument
label is used to specify the tab label. This may be a string,
or in gWidgetsRGtk2 a glabel. The extra argument index
can be used to specify which page to add to. By default, a new page is
created at the end of the notebook. In gWidgetsRGtk2, the extra argument
override.closebutton can be used to add or not add a close
button in the tab label.
The dispose method will remove the currently selected page
unless it is overridden by the value of dontCloseThese.
The delete(obj, widget,...) method will delete the widget on a
given page. This can then be replaced with the add method.
The length method returns the number of pages.
The names method returns the tab labels.
The names<- method may be used to replace the tab
labels. Something like names(obj)[1]<-"new label" should work.
The "[" method refers to the widgets in the notebook.
The "[<-" method can be used to replace a widget on a notebook page.
