Question

I have an QHBoxLayout with a QTreeWidget on the left, a separator on the middle and a widget on the right.

When I click on the QTreeWidget, I want to change the widget on the right to modify the QTreeWidgetItem

I tried to do this with this code :

def new_rendez_vous(self):
    self.ui.horizontalLayout_4.removeWidget(self.ui.editionFormWidget)
    del self.ui.editionFormWidget
    self.ui.editionFormWidget = RendezVousManagerDialog(self.parent)
    self.ui.editionFormWidget.show()
    self.ui.horizontalLayout_4.addWidget(self.ui.editionFormWidget)
    self.connect(self.ui.editionFormWidget, QtCore.SIGNAL('saved'), self.scheduleTreeWidget.updateData)

def edit(self, category, rendez_vous):
    self.ui.horizontalLayout_4.removeWidget(self.ui.editionFormWidget)
    del self.ui.editionFormWidget
    self.ui.editionFormWidget = RendezVousManagerDialog(self.parent, category, rendez_vous)
    self.ui.editionFormWidget.show()
    self.ui.horizontalLayout_4.addWidget(self.ui.editionFormWidget)
    self.connect(self.ui.editionFormWidget, QtCore.SIGNAL('saved'), self.scheduleTreeWidget.updateData)

def edit_category(self, category):
    self.ui.horizontalLayout_4.removeWidget(self.ui.editionFormWidget)
    del self.ui.editionFormWidget
    self.ui.editionFormWidget = CategoryManagerDialog(self.parent, category)
    self.ui.editionFormWidget.show()
    self.ui.horizontalLayout_4.addWidget(self.ui.editionFormWidget)
    self.connect(self.ui.editionFormWidget, QtCore.SIGNAL('saved'), self.scheduleTreeWidget.updateData)

But it doesn’t work and all the widgets are stacked up on each other :

.

Do you know how I can remove the old widget and next display the new one ?

Answer 1

The most common solution is to use QStackedWidget and put all possible widgets into the stack. When selecting an item, just call setCurrentWidget to display the one you want.
