Python 如何获取gtkDialog';s对空格键触发器的默认响应
我设置了一个messageDialog,因此它的默认响应是gtk.response\u OK,因此当用户点击enter时,即使OK按钮没有焦点,也会单击OK按钮。我还想让空格键触发默认的_响应。最好的方法是什么Python 如何获取gtkDialog';s对空格键触发器的默认响应,python,dialog,gtk,key,key-bindings,Python,Dialog,Gtk,Key,Key Bindings,我设置了一个messageDialog,因此它的默认响应是gtk.response\u OK,因此当用户点击enter时,即使OK按钮没有焦点,也会单击OK按钮。我还想让空格键触发默认的_响应。最好的方法是什么 这是在linux环境中使用Python2.4实现的。很遗憾,我没有升级python的权限。连接到消息对话框上的按键事件信号: def on_dialog_key_press(dialog, event): if event.string == ' ': dialo

按键事件
信号:
def on_dialog_key_press(dialog, event):
if event.string == ' ':
dialog.response(gtk.RESPONSE_OK)
return True
return False
dialog = gtk.MessageDialog(message_format='Some message', buttons=gtk.BUTTONS_OK_CANCEL)
dialog.add_events(gtk.gdk.KEY_PRESS_MASK)
dialog.connect('key-press-event', on_dialog_key_press)
dialog.run()
不过,请记住,改变用户对用户界面的期望通常被认为是不酷的。我在pygtk是一个彻头彻尾的呆子,但我无法让@ptomato的示例+“hello world”样板工作,除非我响应space并返回并添加对dialog.destroy()的调用。不管它值多少钱,都要接受它
#!/usr/bin/env python
# example helloworld.py
import pygtk
pygtk.require('2.0')
import gtk
def md_event(dialog, event):
if event.keyval in (gtk.keysyms.Return, gtk.keysyms.space):
dialog.response(gtk.RESPONSE_OK)
dialog.destroy()
return True
elif event.keyval == gtk.keysyms.Escape:
dialog.response(gtk.RESPONSE_CANCEL)
dialog.destroy()
return True
return False
class HelloWorld:
# This is a callback function. The data arguments are ignored
# in this example. More on callbacks below.
def hello(self, widget, data=None):
print "Hello World"
# Another callback
def destroy(self, widget, data=None):
gtk.main_quit()
def create_message_dialog(self, x, y):
md = gtk.MessageDialog(buttons=gtk.BUTTONS_OK_CANCEL, message_format="wawawawaaaaa")
md.add_events(gtk.gdk.KEY_PRESS_MASK)
md.connect("key-press-event", md_event)
result = md.run()
print result
def __init__(self):
# create a new window
self.window = gtk.Window(gtk.WINDOW_TOPLEVEL)
# Here we connect the "destroy" event to a signal handler.
# This event occurs when we call gtk_widget_destroy() on the window,
# or if we return FALSE in the "delete_event" callback.
self.window.connect("destroy", self.destroy)
# Sets the border width of the window.
self.window.set_border_width(10)
self.button2 = gtk.Button("Message Dialog")
self.button2.connect("clicked", self.create_message_dialog, None)
self.window.add(self.button2)
self.button2.show()
# and the window
self.window.show()
def main(self):
# All PyGTK applications must have a gtk.main(). Control ends here
# and waits for an event to occur (like a key press or mouse event).
gtk.main()
def run_hello():
hello = HelloWorld()
hello.main()
# If the program is run directly or passed as an argument to the python
# interpreter then create a HelloWorld instance and show it
if __name__ == "__main__":
run_hello()
奇怪。。。除了
导入gtk
,我没有从我的帖子中编辑任何内容!我尝试这样做的唯一原因是它是被特别要求的。
