MPS 2021.2 Help

Project tool window

This tool window lets you look at your project from various viewpoints and perform the tasks such as creating new items (nodes, models, modules, and so on), opening nodes or files in the editor, navigating to the code fragment of interest, and more.

Most of the functions in this tool window are accessed as context menu commands in the content pane and via associated shortcuts.

Also, the view contains the Scratches and Consoles folder that lets you manage created scratch files, database consoles, and extension scripts.

Views

The tool window has several views:

  • Logical View. In this view, all the project nodes are shown organized logically into their containing modules, models and virtual folders.

  • File System. In this view, all the project files are shown organized by their physical location on the directory structure.

  • Favorites. In this view, the user-preferred project elements are shown.

To switch between views, press Alt+Right/ Alt+Left or select the desired view from the list on the title bar. You can also display each view in a separate tab: click Settings and disable the Group Tabs option.

To configure a view, use the corresponding options in the title bar context menu. The necessary options can also be accessed by clicking Settings on the title bar.

Preview files

There are two ways to preview files without opening each one in a separate tab:

  • Use the file preview popup — select a file in the Project tool window and press Space.

  • Enable the preview tab — click the Show Options Menu button and select Enable Preview Tab.

Show tree indent guides

In the Project tool window, you can display vertical lines that mark indent levels and help you better understand the hierarchy of the components in your project. To display these lines, enable Show tree indent guides on the Appearance and Behavior | Appearance page of the IDE settings Ctrl+Alt+S.

Title bar context menu

The context menu that appears by right-clicking the title bar or clicking Settings, provides settings for project views.

The following table lists and briefly explains the available commands and options.

ItemShortcutDescription
Show Members

If this option is on, the nodes in the tree, when unfolded, will show the contained children, properties and references.

Folders Always on Top If the option is on, virtual folders are shown above the root nodes. Otherwise, all items are sorted alphabetically, and root nodes and virtual folders appear intermixed.
Sort Roots by Concept

Root nodes of the same concept will be grouped together inside a model.

Show @descriptor models in Generators

These models are normally hidded. This option makes them visible in the tree.

Group TabsIf this option is on, there is a list in the left-hand part of the title bar from which you can select the necessary view. If this option is off, the views are represented by tabs which appear in the left-hand part of the title bar.
show views as tabs
View ModeThis option lets you control general appearance and behavior of the tool window.
Move toTo associate the tool window with a different tool window bar, select this command, and then select the destination tool window bar (Top, Left, Bottom or Right).
Resize

To resize the tool window by moving one of its borders, select this command, and then select the necessary Stretch to option.

Note that this command is not available for the floating mode.

Remove from Sidebar

This command hides the tool window, removes the button for showing and hiding the tool window and removes the tool window from the quick access menu (tb shown or tb hidden).

To open the tool window again (and restore the associated features), use the main menu: View | Tool Windows | <Window Name> or press Alt+1.
