我目前正在開發一個使用python-webkit的Python瀏覽器。

上面的源代碼是爲了管理主窗口而編寫的。

如何使用webview.get_uri（）方法返回值在標籤內持續顯示當前URL？

在此先感謝

Answer 1

while True: 
    updateLocationBar() # ;) 

當然地址欄已經提供了這一點？你可以打電話給你的標籤修改功能無論self.webview.open()通過寫一個包裝像

def self.webview.mysuperawesomeopen(uri): 
    updateLocationBar() 
    self.webview.open(uri) 

，然後適當地修改呼叫調用。或者，如果你不想改變來電，只需將現有.open()功能像

self.webview.openit = self.window.open 
def self.window.open(uri): 
    updateLocationBar() 
    self.webview.openit(uri) 

編輯：你也可以使用一個函數裝飾上self.window.open()像

def labelled(f): 
    def labelgo(*args, **kwargs): 
     updateLocationBar(*args, **kwargs) 
     self.webview.open(*args, **kwargs) 
    return labelgo 

@labelled # You add this and leave the rest of self.window.open alone 
def self.window.open(uri): 
    ... 

這將是一個更好的解決方案，如果你想推廣（你會使標籤裝飾器更通用 - 我把這個簡單的例子）。
