我正试图让这个python代码在鼠标悬停在托盘图标上并滚动鼠标滚轮时作出反应,我在网上找不到任何示例。这就是我到目前为止所做的,它对滚动滚轮没有反应......
#!/usr/bin/python
APPNAME = "My App"
ICON = "/usr/share/pixmaps/firefox.png"
import appindicator as AI
import gtk
def sayhello(item):
print "menu item selected"
def scroll(aai, ind, steps):
print "hello" # doesn't print anything
def makemenu():
' Set up the menu '
menu = gtk.Menu()
check = gtk.MenuItem('Check')
exit = gtk.MenuItem('Quit')
check.connect('activate', sayhello)
exit.connect('activate', gtk.main_quit)
menu.append(check)
menu.append(exit)
return menu
def startapp():
ai = AI.Indicator(APPNAME, ICON, AI.CATEGORY_APPLICATION_STATUS)
ai.set_status(AI.STATUS_ACTIVE)
ai.connect("scroll-event", scroll)
ai.set_menu(makemenu())
gtk.main()
startapp()
如何检测滚轮运动?
答案 0 :(得分:3)
这是连接到鼠标滚动事件的正确方法,代码确实有效,在两个12.04系统上进行了测试。可能有一个错误,因为其中一个测试运行的前几个测试也没有用,但之后很好。
如果你是从头开始我会建议使用pygobject(Gtk3)而不是pygtk(Gtk2),因为它不再开发。作为测试的一部分,我确实将您的脚本转换为pygobject并修复了显示菜单:
#!/usr/bin/env python
APPNAME = "My App"
ICON = "/usr/share/pixmaps/firefox.png"
from gi.repository import AppIndicator3 as AI
from gi.repository import Gtk
def sayhello(item):
print "menu item selected"
def scroll(aai, ind, steps):
print "hello" # doesn't print anything
def makemenu():
' Set up the menu '
menu = Gtk.Menu()
check_item = Gtk.MenuItem('Check')
exit_item = Gtk.MenuItem('Quit')
check_item.connect('activate', sayhello)
check_item.show()
exit_item.connect('activate', Gtk.main_quit)
exit_item.show()
menu.append(check_item)
menu.append(exit_item)
menu.show()
return menu
def startapp():
ai = AI.Indicator.new(APPNAME, ICON, AI.IndicatorCategory.HARDWARE)
ai.set_status(AI.IndicatorStatus.ACTIVE)
ai.set_menu(makemenu())
ai.connect("scroll-event", scroll)
Gtk.main()
startapp()
