pygtk的clipboard

clipboard = gtk.Clipboard(display, selection)
如果使用的是default gtk.gdk.Display，则
clipboard = gtk.clipboard_get(selection)
也可以使用这个方法：

clipboard = widget.get_clipboard(selection)

editable.cut_clipboard()
editable.copy_clipboard()
editable.paste_clipboard()

比如：

textbuffer.copy_clipboard(clipboard)

textbuffer.cut_clipboard(clipboard, default_editable)

textbuffer.paste_clipboard(clipboard, override_location, default_editable)

textbuffer.add_selection_clipboard(clipboard)
textbuffer.remove_selection_clipboard(clipboard)

clipboard.set_with_data(targets, get_func, clear_func, user_data)
clipboard.set_text(text, len=-1)

def get_func(clipboard, selectiondata, info, data):
def clear_func(clipboard, data):

def my_set_text(self, text, len=-1):
targets = [ ("STRING", 0, 0),
("TEXT", 0, 1),
("COMPOUND_TEXT", 0, 2),
("UTF8_STRING", 0, 3) ]
def text_get_func(clipboard, selectiondata, info, data):
selectiondata.set_text(data)
return
def text_clear_func(clipboard, data):
del data
return
self.set_with_data(targets, text_get_func, text_clear_func, text)
return

clipboard.request_contents(target, callback, user_data=None)

def callback(clipboard, selectiondata, data):

clipboard.request_text(callback, user_data=None)

clipboard.request_targets(callback, user_data=None)

selectiondata = clipboard.wait_for_contents(target)
text = clipboard.wait_for_text()

pygtk的image

image.set_from_pixbuf(pixbuf)
image.set_from_pixmap(pixmap, mask)
image.set_from_image(image)
image.set_from_file(filename)
image.set_from_stock(stock_id, size)
image.set_from_icon_set(icon_set, size)
image.set_from_animation(animation)

size参数如下：

ICON_SIZE_MENU
ICON_SIZE_SMALL_TOOLBA
ICON_SIZE_LARGE_TOOLBA
ICON_SIZE_BUTTON
ICON_SIZE_DND
ICON_SIZE_DIALOG

button = gtk.Button(label=None, stock=None)

带图片的按钮，采用在button内加上box的方式
