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, query 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.

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 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 on the title bar.

Preview files

There is an option that allows the user to preview files without opening each one in a separate tab:

Enable the preview tab: click 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.

Go to Settings | Appearance and Behavior | Appearance.
Set the Show tree indent guides checkbox.

Title bar context menu

The context menu that appears by right-clicking the title bar or clicking the Options button () provides settings for project views.

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

Item	Shortcut	Description
Show Members		If this option is on, the nodes in the tree, when unfolded, will show the contained children, properties and references.
Show Descriptor Models		These models are normally hidden. This option makes them visible in the tree.
Show Errors Only		When selected, only errors are highlighted on nodes in the view. Otherwise, errors as well as warnings are highlighted.
Sort by Name		Sort files alphabetically by their names. The option does not affect the order of folders, they are always sorted alphabetically.
Sort by Concept		Root nodes of the same concept will be grouped together inside a model.
Sort by Modification Time (Newest First/Oldest First)		Sort files by the time they were modified. To display this information, select View \| Appearance \| Details in Tree View from the main menu. The option does not affect the order of folders, they are always sorted alphabetically.
Enable Preview Tab		Enable the preview tab that allows you to view files in a single tab one by one without opening each file in a new tab.
Open Files with Single Click		Open an item in the editor by clicking it in the Project tool window once. Otherwise, you need to double-click items to open them. Note that you cannot disable this option if you enable the preview tab.
Open Directories with Single Click		Expand and collapse directories in the Project tool window by clicking them once. Otherwise, you need to double-click a directory to open it or use the icon next to the directory's name.
Always Select Opened File		If this option is on, MPS automatically locates documents that you open in the editor in the current view of this window.
Edit Scopes		Open the Scopes dialog in which you can create and edit used-defined scopes. Note that this command is available only if the current view is a scope view.
Speed Search		Search for a node in the panel by its name. Nodes hidden underneath collapsed nodes are not considered.
Group Tabs		If 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.
View Mode		This option lets you control general appearance and behavior of the tool window.
Move to		To 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). For full information, refer to the Move tool windows chapter.
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 ( or ). To open the tool window again (and restore the associated features), use the main menu: View \| Tool Windows \| <Window Name> or press `Alt+1`.
Help		This command opens the description of the Project tool window in the MPS online help.
