QFormLayout clear

How can I clear a QFormLayout?

I have tried (Python):

for row in reversed(xrange(self.count())):
    item = self.takeAt(row)
    item.widget().deleteLater()

This looks like it is cleared visually, but rowCount() remains the same.

I think it's a bug...

Just annoying that it seems like no one wants to fix it.

Is there any way to create my own QFormLayout class with the option to remove rows? I've gotten pretty close so far by making a class that inherits from QVBoxLayout, then every time a row is added, I create a QHBoxLayout with a label and field in it. The only problem I'm having is having all of the fields align to the longest label.

Hi,

You can build Qt yourself and apply the patch proposed through the bug report if you're in a hurry.

@elveatles How about a QGridLayout with 2 columns then (label and widget)? The columns would take care of proper alignment.

@Chris-Kawa I've discovered that QGridLayout has the same issue.
