The actual code is here:

http://code.google.com/p/pybotwar/source/browse/qt4view.py


The item that is getting added is the class at line 362.

And the method that tries to remove the original items
is at line 172.




I also made a small example of the problem...

repop.ui is a QMainWindow made with Qt Designer that has
a VBoxLayout laid out with a horizontal spacer horizontally
then laid out with a vertical spacer vertically.

It does not show exactly the same behavior. When this is run,
you can see a blotch where all of the items get written over
one another the 2nd time through.





# repop.py

import os
import sys

from PyQt4 import QtCore, QtGui, uic, QtSvg
from PyQt4.Qt import QHBoxLayout

uidir = 'data/ui'


class RP(QtGui.QMainWindow):
    def __init__(self):
        QtGui.QMainWindow.__init__(self)
        uifile = 'repop.ui'
        uipath = os.path.join(uidir, uifile)
        RPClass, _ = uic.loadUiType(uipath)
        self.ui = RPClass()
        self.ui.setupUi(self)

        self.pop()
        self.repop()

    def pop(self):
        for n in range(10):
            ri = RI(str(n))
            self.ui.vl.addLayout(ri)

    def repop(self):
        vl = self.ui.vl
        while vl.count():
            item = vl.itemAt(0)
            vl.removeItem(item)

        self.pop()


class RI(QtGui.QHBoxLayout):
    def __init__(self, name, rend=None):
        QtGui.QHBoxLayout.__init__(self)

        vl = QtGui.QVBoxLayout()
        nm = QtGui.QLabel(name)
        vl.addWidget(nm)

        self.addLayout(vl)



if __name__ == '__main__':
    app = QtGui.QApplication(sys.argv)
    rp = RP()
    rp.show()
    app.exec_()

# end


Thanks for any suggestions.
