Support this feature from Chainladder:

Establish a preliminary navigation pane. This pane should be collapsible and contain a list of projects organized hierarchically by jurisdiction and LOB. Each level of the hierarchy should be collapsible as well.

Chainladder has a feature to extract the valuation date from the triangle. This should be visible in the GUI.

Unless a database connection is established, the user should not be able to do things such as add new projects, view triangles, etc.

My thoughts are in a hierarchical navigation tree, if a user clicks on a higher-level tier, they should be able to see aggregated triangles:

Use mouse events for this

We will start out by being able to view single triangles, but we should support things like summing up multiple triangles:

When I look at a table like this, it seems like there can be a large variety of reports possible. Rather than have every report I can think of as part of the base installation, we should allow users to import their own reports if they made something like the following outside of FASLR:

Assuming the organization has the data, the user should be able to drill down from triangle view all the way down to the claims that make up the triangle. It would also be nice if the user can look at a claim report for an individual claim, like the one below:

Reproduction steps:

1. Open settings dialog
2. Delete configuration
3. Accept Changes

Then the window freezes.

It would be cool to support this feature in chainladder:

If the user presses something like ALT+F, it should activate the file menu.

The context menu should at least have an option for creating a new project

One of the first things a user will do is connect to a database. Upon pressing the "connect" button, the user will see a dialog box in which they can enter the database parameters. I could use QLineEdit to create the fields for these parameters.

Since this is used as a test for the reasonableness of the development technique, it should be accessible to the user shortly after triangle importation.

raa = cl.load_sample("raa")
print(
    "Correlation across valuation years? ",
    raa.valuation_correlation(p_critical=0.1, total=True).z_critical.values,
)

Support this feature from Chainladder:

In the navigation pane, one should be able to right click a project, and then click export. The user should have the option to export metadata and results only, or to export data as well, at varying amounts of depth with respect to the data pipeline from origin to reporting.

For example, when hovering over this delete button, the main window status is blank, but should read, "Delete the user config file and quit the application."

    def user_layout(self):
        layout = QVBoxLayout()
        delete_configuration_button = QPushButton("Delete Configuration")
        delete_configuration_button.setStatusTip("Delete the user config file and quit the application.")
        layout.addWidget(delete_configuration_button)
        layout.setAlignment(Qt.AlignTop)
        # noinspection PyUnresolvedReferences
        delete_configuration_button.clicked.connect(self.delete_configuration)
        self.user_container.setLayout(layout)

This happens when trying to make or use an existing db, but you cancel.
