python - PyQt QLineEdit 和 'paste' 事件？

Question

我到处搜索，但找不到有关在将文本粘贴到 PyQt4 QLineEdit 中时触发槽/事件的示例？

Answer 1

将以下代码添加到您的 MyForm 类中:

内部__init__()

self.ui.lineEdit_URL.textChanged.connect(self.valueChanged)

定义新方法:

def valueChanged(self, text):
     if QtGui.QApplication.clipboard().text() == text:
         self.pasteEvent(text)

定义另一种方法:

def pasteEvent(self, text):
    # this is your paste event, whenever any text is pasted in the
    # 'lineEdit_URL', this method gets called.
    # 'text' is the newly pasted text.

    print text
