Lab - reload surface mesh with selection

[janetournois]

Issue Details

• Load a surface mesh, and a selection (either from two separate files or stored in one file like .om file format
• make operations (or not)
• click "Reload Item From File"

Depending on the operations scenario, Lab either crashes, or does not reload the selection.

Indeed, in MainWindow.cpp, the function reloadItem() does not take into account the "dependent" items like the selection_item. This should be fixed

Environment

• CGAL version: 6.0.1

void MainWindow::reloadItem(Item* item) {
    if (!item) {
        qDebug() << "No item provided for reload.";
        return;
    }

    // Step 1: Identify and store dependent items
    QList<Item*> dependentItems;
    if (item->hasDependencies()) {
        dependentItems = item->getDependencies();
    }

    // Step 2: Reload the main item
    bool reloadSuccessful = item->reloadFromFile();
    if (!reloadSuccessful) {
        qDebug() << "Failed to reload item from file.";
        return;
    }

    // Step 3: Handle dependent items
    for (Item* dependentItem : dependentItems) {
        if (dependentItem) {
            bool dependentReloadSuccessful = dependentItem->reloadFromFile();
            if (!dependentReloadSuccessful) {
                qDebug() << "Failed to reload dependent item:" << dependentItem->name();
                // Optionally, recreate or update dependent items as needed
            }
        }
    }

    // Step 4: Update UI and consistency
    updateUI();
    qDebug() << "Reloaded item and its dependencies successfully.";
}
