Python中GTK3对话框,Gtk.Entry的"回车键"应触发OK按钮
我有以下用Python和Gtk3写的代码。
from gi.repository import Gtk
class DialogTaskDescription(Gtk.Dialog):
def __init__(self):
Gtk.Dialog.__init__(self, "Create ToDo.txt Entry", 0, 0,
(Gtk.STOCK_CANCEL, Gtk.ResponseType.CANCEL,
Gtk.STOCK_OK, Gtk.ResponseType.OK))
self.set_default_size(150, 100)
hbox = Gtk.Box(orientation=Gtk.Orientation.HORIZONTAL, spacing=6)
self.label = Gtk.Label("Task Description:")
self.taskDescription = Gtk.Entry()
hbox.pack_start(self.label, False, True, 0)
hbox.pack_start(self.taskDescription, True, True, 0)
box = self.get_content_area()
box.add(hbox)
self.show_all()
def getTaskDescription(self):
return self.taskDescription.get_text()
class TaskDescription:
def __init__(self):
self.dialog = DialogTaskDescription()
def getTaskDescription(self):
response = self.dialog.run()
taskDescription = ''
if response == Gtk.ResponseType.OK:
taskDescription = self.dialog.getTaskDescription()
self.dialog.destroy()
return taskDescription
现在我想让用户在“taskDescription”输入框里按下回车键时,自动点击确认按钮。有没有什么办法可以做到这一点?非常感谢!
编辑:
我找到了解决办法……虽然不确定这是否是正确的方法,但这个方法有效:
我在DialogTaskDescription()的初始化方法里添加了以下几行:
# enter key should trigger the default action
self.taskDescription.set_activates_default(True)
# make OK button the default
okButton = self.get_widget_for_response(response_id=Gtk.ResponseType.OK)
okButton.set_can_default(True)
okButton.grab_default()

这是另一个关于Gtk3对话框的例子,它会询问一些SpinButton的值:
class Days_Back:
def __init__(self):
self.days = self.days_back()
def days_back(self, title="Days Back", max_number=10):
__title__ = title
flags = Gtk.DialogFlags.MODAL
dialog = Gtk.Dialog(title=__title__,
flags=flags,
buttons=(Gtk.STOCK_CANCEL, Gtk.ResponseType.CANCEL,
Gtk.STOCK_OK, Gtk.ResponseType.OK))
dialog.set_default_response(Gtk.ResponseType.OK)
box = dialog.get_content_area()
adjustment = Gtk.Adjustment(1, 1, max_number, 1, 5, 0)
spin_button = Gtk.SpinButton(adjustment=adjustment, climb_rate=1, digits=0)
spin_button.show()
spin_button.set_activates_default(True)
box.add(spin_button)
response = dialog.run()
dialog.destroy()
if response == Gtk.ResponseType.OK:
logging.debug("you choosed Gtk.ResponseType.OK")
return spin_button.get_value_as_int()
else:
exit(response)
