从pyqt4的QGridLayout中的仅QLineEdit小部件提取文本

Question

I have a QGrid Layout with around 15 widgets consisting of QLabels , QLineEdits and QComboBoxes. I would like a function which extracts the text from only the QLineEdit widgets.

What I mean is something like this

for i in range(self.grid.count()):
    if self.grid.itemAt.widget(i).Type == QtGui.QLineEdit: //Not able to figure out the syntax 
        print self.grid.itemAt.widget(i).text()

Could someone help out with the syntax?

Answer 1

You are using the wrong syntax for itemAt . Try this:

    from PyQt4.QtGui import *
    ...
    for i in range(self.grid.count()):
        w = self.grid.itemAt(i).widget()
        print isinstance(w, QLineEdit)

It should work just fine.
