pyqt QTreeWidget setItemWidget dissapears after drag/drop
- by mleep
I'm trying to keep a widget put into a QTreeWidgetItem after a reparent (drag and drop) using QTreeWidget.setItemWidget()
But the result, if you compile the following code - is that the widget inside the QTreeWidgetItem disappears.
Any idea why? What code would fix this (repopulate the QTreeWidgetItem with the widget I guess?)
from PyQt4.QtCore import *
from PyQt4.QtGui import *
class InlineEditor (QWidget):
_MUTE = 'MUTE'
def __init__ (self, parent):
QWidget.__init__ (self, parent)
self.setAutoFillBackground (True)
lo = QHBoxLayout()
lo.setSpacing(4)
self._cbFoo = QComboBox()
for x in ["ABC", "DEF", "GHI", "JKL"]:
self._cbFoo.addItem(x)
self._leBar = QLineEdit('', self)
lo.addWidget (self._cbFoo, 3)
lo.addSpacing (5)
lo.addWidget (QLabel ( 'Bar:'))
lo.addWidget (self._leBar, 3)
lo.addStretch (5)
self.setLayout (lo)
class Form (QDialog):
def __init__(self,parent=None):
QDialog.__init__(self, parent)
grid = QGridLayout ()
tree = QTreeWidget ()
# Here is the issue?
tree.setDragDropMode(QAbstractItemView.InternalMove)
tree.setColumnCount(3)
for n in range (2):
i = QTreeWidgetItem (tree) # create QTreeWidget the sub i
i.setText (0, "first" + str (n)) # set the text of the first 0
i.setText (1, "second")
for m in range (2):
j = QTreeWidgetItem(i)
j.setText (0, "child first" + str (m))
#b1 = QCheckBox("push me 0", tree) # this wont work w/ drag by itself either
#tree.setItemWidget (tree.topLevelItem(0).child(1), 1, b1)
item = InlineEditor(tree) # deal with a combination of multiple controls
tree.setItemWidget(tree.topLevelItem(0).child(1), 1, item)
grid.addWidget (tree)
self.setLayout (grid)
app = QApplication ([])
form = Form ()
form.show ()
app.exec_ ()
