How to scroll QListWidget to selected item

2024/12/9 20:59:39

The code below creates a single dialog window with QListWidget and QPushButton. Clicking the button fires up a scroll() function which finds and selects an "ITEM-0011".

I wonder if there is a way to scroll the list widget so the selected ITEM-0011 is at the top edge of QListWidget? Here is how the end result should look like:

enter image description here

from PyQt4 import QtCore, QtGui
app=QtGui.QApplication([])def scroll():item = listWidget.findItems('ITEM-0011', QtCore.Qt.MatchRegExp)[0]item.setSelected(True)window = QtGui.QDialog()
window.setLayout(QtGui.QVBoxLayout())
listWidget = QtGui.QListWidget()
window.layout().addWidget(listWidget)for i in range(100):QtGui.QListWidgetItem('ITEM-%04d'%i, listWidget)btn = QtGui.QPushButton('Scroll')
btn.clicked.connect(scroll)
window.layout().addWidget(btn)
window.show()
app.exec_()
Answer

The list-widget has a scrollToItem method that will scroll an item to a specific position:

def scroll():item = listWidget.findItems('ITEM-0011', QtCore.Qt.MatchRegExp)[0]item.setSelected(True)listWidget.scrollToItem(item, QtGui.QAbstractItemView.PositionAtTop)
