基于类,我有一个包含一个button
和progressbar
的窗口,每当单击按钮时,都会发生两件事:
1 - 应将对话框中的输入值传递给
class ABCD
2 - 当我们的班级
ABCD()
做他的事情时,我们的进度条是否应该定期跳动,直到班级 ABCD() 完成过程。
所以问题是进度条只脉冲一次,然后卡在那里直到类 ABCD() 完成,然后它开始有规律地脉冲。
这是我的尝试:
import gi,time
gi.require_version('Gtk', '3.0')
from gi.repository import Gtk, Gdk, GObject
class DialogExample(Gtk.Dialog):
def __init__(self, parent):
Gtk.Dialog.__init__(self, "My Dialog", parent, 0,
(Gtk.STOCK_CANCEL, Gtk.ResponseType.CANCEL,
Gtk.STOCK_OK, Gtk.ResponseType.OK))
self.set_default_size(150, 100)
self.Myinput = Gtk.Entry()
box = self.get_content_area()
box.add(self.Myinput)
self.show_all()
class DialogWindow(Gtk.Window):
def __init__(self):
Gtk.Window.__init__(self, title="Dialog Example")
self.set_border_width(6)
Hbox = Gtk.Box(orientation=Gtk.Orientation.HORIZONTAL)
self.add(Hbox)
self.button = Gtk.Button("Open dialog")
self.button.connect("clicked", self.on_button_clicked)
Hbox.pack_start(self.button, True, True, 0)
self.progressbar = Gtk.ProgressBar()
Hbox.pack_start(self.progressbar, True, True, 0)
#~~~~~~ Progress Bar
def on_timeout(self, user_data):
"""
Update value on the progress bar
"""
if self.activity_mode:
self.progressbar.pulse()
else:
new_value = self.progressbar.get_fraction() + 0.01
if new_value > 1:
new_value = 0
self.progressbar.set_fraction(new_value)
# As this is a timeout function, return True so that it
# continues to get called
return True
def on_button_clicked(self, widget):
dialog = DialogExample(self)
response = dialog.run()
if response == Gtk.ResponseType.OK:
variable = dialog.Myinput.get_text()
print("start")
dialog.destroy()
#ProgressBar time function
self.timeout_id = GObject.timeout_add(50, self.on_timeout, None)
self.activity_mode = False
self.progressbar.pulse()
#this for Updating the Windows and make the progressbar pulsing while waiting
# the class ABCD finish his stuff, finally should stop pulsing.
while Gtk.events_pending():
Gtk.main_iteration_do(False)
passing_instance = ABCD(variable)
class ABCD(object):
def __init__(self,value_of_dialog):
self.get_value = value_of_dialog
self.for_add = "______ add was done"
self.final_value = self.get_value+self.for_add
time.sleep(10)
print("gonna be finished")
print(self.final_value)
win = DialogWindow()
win.connect("delete-event", Gtk.main_quit)
win.show_all()
Gtk.main()
正如我们在这里看到的,我已经尝试在这部分代码中制作脉冲并刷新窗口
self.timeout_id = GObject.timeout_add(50, self.on_timeout, None)
self.activity_mode = False
self.progressbar.pulse()
#this for Updating the Windows and make the progressbar pulsing while waiting
# the class ABCD finish his stuff, finally should stop pulsing.
while Gtk.events_pending():
Gtk.main_iteration_do(False)
否则,因为
my class ABCD()
我time.sleep(10)
应该只在 10 秒后才停止该时间的进度条脉冲。
这段代码应该如何,我需要有人为我提供正确的代码,几乎没有解释。
