我编辑了代码,以便现在显示3个按钮。有人请告诉我如何制作它,以便当我点击Helloworld按钮并在另一个窗口中弹出名为Helloworld.py的应用程序时。对于其他2个按钮
!/usr/bin/env python
# menu.py
import pygtk
pygtk.require('2.0')
import gtk
class MenuExample:
def __init__(self):
# create a new window
window = gtk.Window(gtk.WINDOW_TOPLEVEL)
window.set_size_request(200, 100)
window.set_title("GTK Menu Test")
window.connect("delete_event", lambda w,e: gtk.main_quit())
# Init the menu-widget, and remember -- never
# show() the menu widget!!
# This is the menu that holds the menu items, the one that
# will pop up when you click on the "Root Menu" in the app
menu = gtk.Menu()
# Next we make a little loop that makes three menu-entries for
# "test-menu". Notice the call to gtk_menu_append. Here we are
# adding a list of menu items to our menu. Normally, we'd also
# catch the "clicked" signal on each of the menu items and setup a
# callback for it, but it's omitted here to save space.
for i in range(3):
# Copy the names to the buf.
buf = "Test-undermenu - %d" % i
# Create a new menu-item with a name...
menu_items = gtk.MenuItem(buf)
# ...and add it to the menu.
menu.append(menu_items)
# Do something interesting when the menuitem is selected
menu_items.connect("activate", self.menuitem_response, buf)
# Show the widget
menu_items.show()
# This is the root menu, and will be the label
# displayed on the menu bar. There won't be a signal handler attached,
# as it only pops up the rest of the menu when pressed.
root_menu = gtk.MenuItem("Root Menu")
root_menu.show()
# Now we specify that we want our newly created "menu" to be the
# menu for the "root menu"
root_menu.set_submenu(menu)
# A vbox to put a menu and a button in:
vbox = gtk.VBox(False, 0)
window.add(vbox)
vbox.show()
# Create a menu-bar to hold the menus and add it to our main window
menu_bar = gtk.MenuBar()
vbox.pack_start(menu_bar, False, False, 2)
menu_bar.show()
# Create a button to which to attach menu as a popup
button = gtk.Button("HelloWorld")
button.connect_object("event", self.button_press, menu)
vbox.pack_end(button, True, True, 2)
button.show()
button2 = gtk.Button("Scrible")
button2.connect_object("event", self.button_press, menu)
vbox.pack_end(button2, True, True, 2)
button2.show()
button3 = gtk.Button("Final")
button3.connect_object("event", self.button_press, menu)
vbox.pack_end(button3, True, True, 2)
button3.show()
# And finally we append the menu-item to the menu-bar -- this is the
# "root" menu-item I have been raving about =)
menu_bar.append (root_menu)
# always display the window as the last step so it all splashes on
# the screen at once.
window.show()
# Respond to a button-press by posting a menu passed in as widget.
#
# Note that the "widget" argument is the menu being posted, NOT
# the button that was pressed.
def button_press(self, widget, event):
if event.type == gtk.gdk.BUTTON_PRESS:
widget.popup(None, None, None, event.button, event.time)
# Tell calling code that we have handled this event the buck
# stops here.
return True
# Tell calling code that we have not handled this event pass it on.
return False
def button2_press(self, widget, event):
if event.type == gtk.gdk.BUTTON2_PRESS:
widget.popup(None, None, None, event.button, event.time)
return True
return False
def button3_press(self, widget, event):
if event.type == gtk.gdk.BUTTON3_PRESS:
widget.popup(None, None, None, event.button, event.time)
return True
return False
# Print a string when a menu item is selected
def menuitem_response(self, widget, string):
print "%s" % string
def main():
gtk.main()
return 0
if __name__ == "__main__":
MenuExample()
main()
答案 0 :(得分:2)
你可以这样做。我假设您只想执行.py文件,例如helloworld.py等我正在使用来自 subprocess 的 Popen 来执行python(不假设py文件是可执行的)脚本。请注意,我已将脚本编辑为只有一个按钮,这只是为了向您展示这个想法。
import pygtk
pygtk.require('2.0')
import gtk
import subprocess
class Example:
def __init__(self):
window = gtk.Window(gtk.WINDOW_TOPLEVEL)
window.set_size_request(200, 100)
window.set_title("GTK Menu Test")
window.connect("delete_event",
lambda w,e: gtk.main_quit())
vbox = gtk.VBox(False, 0)
window.add(vbox)
vbox.show()
button = gtk.Button("HelloWorld")
button.connect("clicked", self.clicked_helloworld)
vbox.pack_end(button, True, True, 2)
button.show()
window.show_all()
def clicked_helloworld(self, widget):
subprocess.Popen(["python", "helloworld.py"])
def main(self):
gtk.main()
return 0
Example().main()
