Generate a project with application objects from "used by" cross-references

Sometimes one needs to investigate where some field or method is used in the AOT. There may be a long list of AOT paths in the "Used by" form, and having a project with all those application elements may be a good starting point.

Add a button to xRefReferencesUsedByTypedTree form, set its Text property to "Create project" and MultiSelect to Yes:


Override its clicked method and use the following code:

void clicked()
{
    #TreeNodeSysNodeType
 
    XrefPaths xRefPathsLocal;
 
    Set treeNodeLocalPaths;
    SetEnumerator treeNodeLocalPathEnumerator;
 
    SysProjectFilterRunBase     project;
    UtilElements                utilElements;
    ProjectNode                 projectNode;
 
    Dialog                      dialog;
    DialogField                 dialogField;
 
    super();
 
    treeNodeLocalPaths = new Set(Types::String);
 
    for (xRefPathsLocal = xRefPaths_ds.getFirst(true) ?
        xRefPaths_ds.getFirst(true) : xRefPaths_ds.cursor();
        xRefPathsLocal;
        xRefPathsLocal = xRefPaths_ds.getNext())
    {
        treeNodeLocalPaths.add(xRefPathsLocal.Path);
    }
 
    if (treeNodeLocalPaths.elements() == 0)
    {
        info("There are no AOT objects to create the project from.");
        return;
    }
 
    dialog = new dialog("Create project");
    dialogField = dialog.addFieldValue(
        extendedTypeStr(ProjectName), 
        'UsedByProject');
 
    if (dialog.run())
    {
        projectNode = SysTreeNode::createProject(any2str(dialogField.value()));
 
        project = new SysProjectFilterRunBase();
        project.parmProjectNode(projectNode);
        project.grouping(SysProjectGrouping::AOT);
 
        treeNodeLocalPathEnumerator = treeNodeLocalPaths.getEnumerator();
        while (treeNodeLocalPathEnumerator.moveNext())
        {
            utilElements = xUtilElements::findTreeNode(
                treeNode::findNode(
                    SysTreeNode::applObjectPath(
                    treeNodeLocalPathEnumerator.current())),
                false);
 
            if (utilElements.RecId != 0)
            {
                project.doUtilElements(utilElements);
            }
        }
 
        project.write();
    }
}

Now, if you select one or more records in the "used by" grid and press the button, a new project will be created:
