[英]GUI freezes when executing def function. Use threads?
I've made a small program which has 2 buttons and each does certain thing. 我制作了一个小程序,其中有2个按钮,每个按钮都有特定功能。 Here's a simplified version of the code.
这是代码的简化版本。
Thing is it works fine except that the button freezes and stays in a clicked position and whole GUI freezes until the command is completed. 一切正常,除了按钮冻结并停留在单击位置,并且整个GUI冻结直到命令完成为止。 As far as I know threads would be best to use in this situation, but I have no idea how to implement it in this example.
据我所知,在这种情况下最好使用线程,但是我不知道如何在此示例中实现它。
I use glade and pygtk for gui. 我将林间空地和pygtk用于gui。
def do1:
t = 2
#do something
time.sleep(t)
#do something
time.sleep(t)
def do2:
t = 3
#do something
time.sleep(t)
#do something
time.sleep(t)
class we:
wTree = None
def __init__( self ):
self.wTree = gtk.glade.XML( "ui.glade" )
dic = {
"on_buttonSone" : self.sone,
"on_buttonStwo" : self.stwo,
}
self.wTree.signal_autoconnect( dic )
gtk.main()
def sone(self, widget):
i = 0
while i < 3:
t = 1
#do something
i += 1
time.sleep(t)
self.wTree.get_widget("entryResult").set_text("Done.")
def stwo(self, widget):
start = time.clock()
array = ['A','B']
adict = {'A':do1,'B':do2}
for f in array:
adict[f]()
end = time.clock()
elapsed = end - start
gg = round(elapsed,2)
self.wTree.get_widget("entryResult").set_text(str(gg))
go=we()
pyGTK has a whole section of there FAQ devoted to threading . pyGTK的FAQ中有一整节专门讨论线程 。
20.6 seems like a good minimal example. 20.6似乎是一个很好的最小示例。
