I have a GUI where a QListWidget is the central widget. The QListWidgetItems are composed of a custom widget that include a Graphics area and a QTable.
When I click on the graphics area, or on the table, the parent QListWidgetItem is not selected
See Picture of the GUI I'm working on
The red border around the top QListWidgetItem indicates that is the one that is currently selected.
From the Input on the table in the second QListWidgetItem, you can see I'm inputting text into the table widget there.
How can I make it so that if I click anywhere on that QListWidgetItem, including its child widgets, that the corresponding item is selected?
For reference, here is some of the relevant code:
class MainWindow(QMainWindow):
move_splitter = Signal(int, int)
def __init__(self):
super().__init__()
# stuff
self.panels = QListWidget()
self.panels.setAcceptDrops(True)
self.panels.setDragEnabled(True)
self.panels.setDragDropMode(QAbstractItemView.InternalMove)
self.panels.setStyleSheet("QListWidget::item:selected \
{ border: 1px solid red }")
self.panels.setSelectionMode(QAbstractItemView.SingleSelection)
self.setCentralWidget(self.panels)
# more stuff
def add_panel(self):
insert_item = QListWidgetItem()
# Panel inherits from QWidget
new_panel = Panel(parent=insert_item,
splitter_pos=self.initialSplitterPosition)
self.move_splitter.connect(new_panel.setSplitterPosition)
new_panel.slider_position.connect(self.slotSplitterPosition)
insert_item.setSizeHint(new_panel.sizeHint())
insert_item.setFlags(insert_item.flags() | Qt.ItemIsAutoTristate)
insert_item.setCheckState(Qt.PartiallyChecked)
self.panels.insertItem(self.panels.currentRow() + 1, insert_item)
self.panels.setItemWidget(insert_item, new_panel)
EDIT:
With the suggestion of implementing an event filter, I created the following subclass of my table
class ControlTable(QTableWidget):
focusReceived = Signal()
def __init__(self, parent=None):
super().__init__()
def focusInEvent(self, event):
if event.type() == QFocusEvent.gotFocus:
self.focusReceived.emit()
QTableWidget.focusInEvent(self, event)
In my panel function, I created a signal and a slot to capture that signal and emit a signal to the MainWindow with which QListWidgetItem should be selected
class Panel(QWidget):
slider_position = Signal(int, int)
select_me = Signal(QObject)
def __init__(self, parent=None, splitter_pos=[]):
# stuff
self.table = ControlTable()
self.table.focusReceived.connect(self.childWidgetFocus)
# more stuff
@Slot()
def childWidgetFocus(self):
parent = self.parent_item
self.select_me.emit(parent)
In my mainwindow class I also added
def add_panel(self):
insert_item = QListWidgetItem()
new_panel = Panel(parent=insert_item,
splitter_pos=self.initialSplitterPosition)
new_panel.parent_item = insert_item
new_panel.select_me.connect(self.changeSelection)
# more stuff
@Slot(QObject)
def changeSelection(self, item):
item.setSelected(True)
While the code runs, the change of selection is not happening, am I implementing the wrong event filter?
EDIT2:
Got it working, was using the wrong event filter type, I needed to use QEvent.FocusIn, but now that I look at my code, and looking at the function I'm overwriting, that if statement is unnecessary it would seem.
I also had to change the signal pass type from QObject to QListWidgetItem.
