Custom widget not appearing in QListWidget/QListWidgetItem

robbiecooper

Hi All

I'm using pyQt 5 and trying to display a custom widget within a standard QListWidgetItem, in a standard QListWidget. The code runs but nothing appears. The code isnt fancy;

def addNewSourceFolder(self):
    StartFolder = "/home"
    DirName = QtWidgets.QFileDialog.getExistingDirectory(self, "Choose Source Folder", expanduser("~"), QtWidgets.QFileDialog.ShowDirsOnly) 
    if DirName:
        widgetitems = []
        widgetitems = self.ui.source_directory_view.findItems(DirName, QtCore.Qt.MatchExactly)
        if len(widgetitems) == 0:
            item = QtWidgets.QListWidgetItem()

            picwidget = ShootWidgetItem()
            picwidget.setTextName(DirName)
            picwidget.setTextPath(DirName)
            picwidget.setWidgetIcon("folder_pic.png")
            self.ui.source_directory_view.addItem(item)
            self.ui.source_directory_view.setItemWidget(item, picwidget)

        widgetitems.clear()

The custom widget is as follows;

class ShootWidgetItem(QtWidgets.QWidget):

      def __init__(self, parent=None):
        super(ShootWidgetItem, self).__init__(parent)
        self.data = []
        self.filepath = ""
        self.textQVBoxLayout = QtWidgets.QVBoxLayout()
        self.textNameLabel    = QtWidgets.QLabel()
        self.textPathLabel  = QtWidgets.QLabel()
        self.textQVBoxLayout.addWidget(self.textNameLabel)
        self.textQVBoxLayout.addWidget(self.textPathLabel)
        self.allQHBoxLayout  = QtWidgets.QHBoxLayout()
        self.iconQLabel      = QtWidgets.QLabel()
        self.allQHBoxLayout.addWidget(self.iconQLabel, 0)
        self.allQHBoxLayout.addLayout(self.textQVBoxLayout, 1)
        self.setLayout(self.allQHBoxLayout)
        # setStyleSheet
        self.textNameLabel.setStyleSheet('''
            color: rgb(0, 0, 255);
        ''')
        self.textPathLabel.setStyleSheet('''
            color: rgb(255, 0, 0);
        ''')

      def setTextName (self, text):
        self.textNameLabel.setText(text)

      def setTextPath (self, text):
        self.textPathLabel.setText(text)

      def setWidgetIcon (self, imagePath):
        self.iconQLabel.setPixmap(QtGui.QPixmap(imagePath))

      def getTextName(self):
          return self.textNameLabel.text()

Anyone have any ideas why this is not appearing in the QlistWidget?

Hi,

Might be a silly idea but did you try to show picwidget once ? Just to be sure it's not empty for whatever reason.

@SGaist Thanks for the reply! Not sure why, but this line in addNewSourceFolder did it;

item.setSizeHint(picwidget.sizeHint())
