Hello.
I just copy a small program I've done which generate a notebook with a
close button. Hopefully it will be helpful for you.
#!/usr/bin/env python
# -*- coding:utf-8 -*-
# notebook.py
import pygtk
pygtk.require('2.0')
import gtk
class NotebookExample:
def add_icon_to_button(self,button):
"Function that add the icon to the button"
#Hbox creation
iconBox = gtk.HBox(False, 0)
#Empty image creation
image = gtk.Image()
#Let's get the default gtk close button
image.set_from_stock(gtk.STOCK_CLOSE,gtk.ICON_SIZE_MENU)
#set the relief off
gtk.Button.set_relief(button,gtk.RELIEF_NONE)
#Get the settings of the button
settings = gtk.Widget.get_settings(button)
#w and h dimensions of the button
(w,h) = gtk.icon_size_lookup_for_settings(settings,gtk.ICON_SIZE_MENU)
#modification of the dimensions
gtk.Widget.set_size_request(button, w + 4, h + 4)
image.show()
#pack the image in the box
iconBox.pack_start(image, True, False, 0)
#add the box in the button
button.add(iconBox)
iconBox.show()
return
def create_custom_tab(self,text, notebook, frame):
"Create a custom tab with a label and the button"
#eventbox creation
eventBox = gtk.EventBox()
#Hbox creation
tabBox = gtk.HBox(False, 2)
#"text" label creation
tabLabel = gtk.Label(text)
#creation of a button
tabButton=gtk.Button()
#connect to the "remove_book" function
tabButton.connect('clicked',self.remove_book, notebook, frame)
#add the icon with the previously defined add_icon_to_button
self.add_icon_to_button(tabButton)
eventBox.show()
tabButton.show()
tabLabel.show()
#add label and button
tabBox.pack_start(tabLabel, False)
tabBox.pack_start(tabButton, False)
tabBox.show_all()
#add the box to the eventox
eventBox.add(tabBox)
return eventBox
def remove_book(self, button, notebook, frame):
"Function to remove the page"
#suppress the page. You must give the child widget of the page
notebook.remove(frame)
# you call the previous page
notebook.queue_draw_area(0,0,-1,-1)
def delete(self, widget, event=None):
gtk.main_quit()
return False
def __init__(self):
window = gtk.Window(gtk.WINDOW_TOPLEVEL)
window.connect("delete_event", self.delete)
window.set_border_width(10)
#book generation
notebook = gtk.Notebook()
window.add(notebook)
notebook.show()
# some pages
for i in range(5):
page_number = i + 1
frame = gtk.Frame("Frame %d" % page_number)
frame.set_border_width(10)
frame.set_size_request(100, 75)
frame.show()
label = gtk.Label("In the Frame %d" % page_number)
frame.add(label)
label.show()
eventBox = self.create_custom_tab("Tab %d" % page_number,
notebook, frame)
notebook.append_page(frame, eventBox)
# page you see at the opening
notebook.set_current_page(3)
window.show()
def main():
gtk.main()
return 0
if __name__ == "__main__":
NotebookExample()
main()
I'm sure we can do that more quickly but it works and as you can see
in the code style, I'm not a specialist...
Hope it will help you.
