问题描述
谁能给我一个简单的例子,以这种方式涉及线程.
Can someone give me a simple example involving threads in this manner, please.
我的代码的问题是,当我单击按钮 One 时,GUI 冻结直到完成.我希望按钮在执行 def 时保持响应.我该如何解决?
Problem with my code is that when I click button One, GUI freezes until its finished. I want buttons to stay responsive when def is being executed. How can i fix that?
class fun:
wTree = None
def __init__( self ):
self.wTree = gtk.glade.XML( "ui.glade" )
dic = {
"on_buttonOne" : self.one,
"on_buttonTwo" : self.two,
}
self.wTree.signal_autoconnect( dic )
gtk.main()
def sone(self, widget):
time.sleep(1)
print "1"
time.sleep(1)
print "2"
time.sleep(1)
print "3"
def stwo(self, widget):
time.sleep(1)
print "4"
time.sleep(1)
print "5"
time.sleep(1)
print "6"
do=fun()
请帮助我.
推荐答案
当使用 gtk 时,它将运行一个主循环,并且您将所有事情作为事件安排到 gtk 循环中.你不需要线程来做任何事情.
When using gtk, it will run a main loop, and you schedule everything you want to do as events to the gtk loop. You don't need threads to do anything.
这是一个完整的、完整的、随时可以运行的示例,它使用 glib.timeout_add
来执行您想要的操作.
Here's a complete, full, ready-to-run example that uses glib.timeout_add
to do what you want.
请注意,单击两个按钮(或多次单击一个按钮)不会冻结 gui 并且所有事情都同时"发生...
Note that clicking on both buttons (or multiple times on a button) doesn't freeze the gui and everything happens "at the same time"...
import gtk
import glib
def yieldsleep(func):
def start(*args, **kwds):
iterable = func(*args, **kwds)
def step(*args, **kwds):
try:
time = next(iterable)
glib.timeout_add_seconds(time, step)
except StopIteration:
pass
glib.idle_add(step)
return start
class Fun(object):
def __init__(self):
window = gtk.Window()
vbox = gtk.VBox()
btnone = gtk.Button('one')
btnone.connect('clicked', self.click_one)
btnone.show()
vbox.pack_start(btnone)
btntwo = gtk.Button('two')
btntwo.connect('clicked', self.click_two)
btntwo.show()
vbox.pack_start(btntwo)
vbox.show()
window.add(vbox)
window.show()
@yieldsleep
def click_one(self, widget, data=None):
yield 1 #time.sleep(1)
print '1'
yield 1 #time.sleep(1)
print '2'
yield 1 #time.sleep(1)
print '3'
@yieldsleep
def click_two(self, widget, data=None):
yield 1 #time.sleep(1)
print '4'
yield 1 #time.sleep(1)
print '5'
yield 1 #time.sleep(1)
print '6'
do = Fun()
gtk.main()
