为什么未从全局gtk绑定程序调用的函数中引发wxframe? [英] Why wxframe isn't raised from a function called with global gtk binder?

问题描述

好的，为什么这个简单的应用程序不起作用. 我花了一天时间对此进行调查，但一无所获.

Ok, why this simple app dosn't work. I've spent one day investigating this and got nothing.

import wx, os
import gtk
import keybinder

class FrameWithHotKey(wx.Frame):

    def __init__(self, *args, **kwargs):
        wx.Frame.__init__(self, *args, **kwargs)
        keybinder.bind("<Ctrl>period", self.toggle_shown)

    def toggle_shown(self):
        # windowNow id
        if self.IsShown():
            self.Hide()
        else:
            self.Show()
            self.Raise()


if __name__ == '__main__':
    app = wx.PySimpleApp()
    frame = FrameWithHotKey(None)
    app.MainLoop()

我不知道为什么，但是有时候(尤其是当我通过单击面板上的应用来启动应用程序时)，提高无法正常工作，并且我得到了Flash图标，而不是升高的窗口.

I don't know why, but sometimes (especially when I raise apps by clicking on them on panel) raising dosen't work and I got flash icon instead of raised window.

更新

好，我回到主题并注意这些..

Ok, i return to the topic and notice these..

1. 上面的例子对我有用..奇怪

2. 我隔离了下面的代码所示的奇怪行为..这与wnck lib有关.因此，如果通过打开新窗口(在窗口上单击鼠标左键-test1)停用了我的应用程序窗口，那么raise效果很好，但是如果其他窗口(用您的任何一个替换"opera")用wnck(通过右键单击-test2)激活，则动作失败

1. above example works for me.. strange

2. i isolated strange behaviour which below code shows.. it's something related with wnck lib. So if my app window is deactivated by open new window (left click on window - test1) then raise works perfect, but if other window (replace 'opera' with any of Yours) is activated with wnck(by right click - test2) then actvation fails

导入日志 导入子流程 导入时间 导入wnck 导入wx

import logging import subprocess import time import wnck import wx

logging.basicConfig(level = logging.DEBUG)

logging.basicConfig(level=logging.DEBUG)

MyFrame类(wx.Frame):

class MyFrame(wx.Frame):

def __init__(self, parent, title=''):
    wx.Frame.__init__(self, parent, title=title)
    self.Centre()
    self.Bind(wx.EVT_LEFT_DOWN, self.test1)
    self.Bind(wx.EVT_RIGHT_DOWN, self.raise_window)

def test1(self, evt):
    logging.debug('losing..')
    subprocess.Popen(['xterm'])
    time.sleep(1)
    self.Raise()
    logging.debug('lost')

def lose_focus_by_wnck(self):
    screen = wnck.screen_get_default()

    import gtk
    while gtk.events_pending():
        gtk.main_iteration(False)

    wins = screen.get_windows()
    logging.debug('wins: {0}'.format(wins))
    for win in  wins:
        app_name = win.get_application().get_name()
        logging.debug('app: {0}'.format(app_name))
        if 'opera' in app_name.lower():
            win_id = win.get_xid()
            break
    else:
        win_id = None
    return win_id

def test2(self, evt):
    logging.debug('losing..')
    win_id = self.lose_focus_by_wnck()
    win = wnck.window_get(win_id)
    TIMESTAMP = 0
    win.activate(TIMESTAMP)
    logging.debug('lost')
    time.sleep(1)
    self.Raise()
    logging.debug('raised')

如果名称 =='主要": 应用= wx.PySimpleApp(redirect = False) 框架= MyFrame(无) frame.Show() app.MainLoop()

if name == 'main': app = wx.PySimpleApp(redirect=False) frame = MyFrame(None) frame.Show() app.MainLoop()

有人能理解这种行为，而不是像我感觉的那样非常有用的wtf吗? :)

Does anybody understand this behaviour instead of very helpful wtf like i feel? :)

推荐答案

什么是keybinder?您正在使用AcceleratorTable吗?参见 http://www.blog.pythonlibrary.org/2010/12/02/wxpython-keyboard-shortcuts-accelerators/了解更多信息.我认为您不能将pyGtk与wxPython混合使用.

What is keybinder? Are you using an AcceleratorTable? See http://www.blog.pythonlibrary.org/2010/12/02/wxpython-keyboard-shortcuts-accelerators/ for more info. I don't think you can mix pyGtk with wxPython.
