PyQt的應用程序加載完成事件

Question

如果我的結構看起來像這樣...

from PyQt4 import QtCore, QtGui 
from PyQt4.QtGui import QDialog,QImage,QPixmap 
from PyQt4.QtCore import * 
from PyQt4.QtGui import * 
from appView import Ui_View 
# this is designer .ui file converted to .py via pyuic4 cmd 

class AppWindow(QDialog, Ui_View): 
    def __init__(self): 
     QDialog.__init__(self) 
     # Set up the user interface from Designer. 
     self.setupUi(self) 
     self.setupEvents() 
    def setupEvents(): 
     print ("setting up events") 

def onResize(event): 
     print event 
def main(): 
    app = QtGui.QApplication(sys.argv) 
    myapp = AppWindow() 
    myapp.resizeEvent = onResize 
    myapp.show() 
    sys.exit(app.exec_()) 

if __name__ == '__main__': 
    main() 

問題：

1. 我怎樣才能得到應用加載完成事件從PyQt的在 AppWindow類，讓我知道它的構造器已經完成運行？
2. 如何在AppWindow類中獲取應用程序調整大小事件？
   我可以得到 這在主要功能和調整它，但如果AppWindow類有能力 傾聽和處理它：什麼是最好的辦法呢？ 這應該如上完成嗎？

解答：

1. 剛開始一個單次計時器與QApplication調用上AppWindows正確的方法。
2. 只需將onResize的編碼放入AppWindows.resizeEvent即可。

例子：

from PyQt4 import QtCore, QtGui 
from PyQt4.QtGui import QDialog,QImage,QPixmap 
from PyQt4.QtCore import * 
from PyQt4.QtGui import * 
import sys 

class AppWindow(QDialog): 

    def __init__(self): 
     QDialog.__init__(self) 
     # Set up the user interface from Designer. 
     #self.setupUi(self) 
     self.setupEvents() 

    def setupEvents(self): 
     print ("setting up events") 

    def resizeEvent(self,event): 
     print event 

    def onQApplicationStarted(self): 
     print 'started' 

def main(): 
    app = QtGui.QApplication(sys.argv) 
    myapp = AppWindow() 
    myapp.show() 
    t = QtCore.QTimer() 
    t.singleShot(0,myapp.onQApplicationStarted) 
    sys.exit(app.exec_()) 

if __name__ == '__main__': 
    main()
