Yes, you can have a QTreeWidget with a top-level item that contains a list of widgets. Here’s an example code snippet that demonstrates how to achieve this:
from PyQt5.QtWidgets import QApplication, QTreeWidgetItem, QWidget, QVBoxLayout, QLabel
app = QApplication([])
tree = QTreeWidget()
tree.setHeaderLabels(['Name', 'Description'])
# Create a top-level item
top_level_item = QTreeWidgetItem(tree)
widget_list = []
# Add widgets to the list
for i in range(3):
widget = QWidget()
layout = QVBoxLayout(widget)
layout.addWidget(QLabel(f"Widget {i}"))
layout.addWidget(QLabel(f"This is widget {i} added to the tree"))
widget_list.append(widget)
# Set the top-level item widget
top_level_widget = QWidget()
top_level_layout = QVBoxLayout(top_level_widget)
for widget in widget_list:
top_level_layout.addWidget(widget)
tree.setItemWidget(top_level_item, 0, top_level_widget)
# Show the tree
tree.show()
app.exec_()
In this code snippet, we create a new QTreeWidget and set its header labels. We then create a new QTreeWidgetItem object as our top-level item and initialize an empty list called widget_list.
We then loop over some range (in this case 3) and create three new QWidget objects using a vertical box layout (QVBoxLayout). We add two QLabel widgets to each of these new widgets: one that displays the label “Widget x”, where x is the current iteration number (0 through 2), and another that displays some sample text.
After creating these widgets, we add them to our widget_list.
Next, we create another new widget using a vertical box layout (QVBoxLayout) called top_level_widget. We loop over our widget_list, adding each one to the top_level_layout using addWidget(). Finally, we call setItemWidget() with our top-level item and our top_level_widget as its content.
When running this code snippet, you should see something like this:
As you can see, we now have a tree widget with a top-level item that contains a list of widgets. Each widget has its own label and description.
