Project tool window
Alt+1
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 provides you with the following 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.
The necessary view is selected from the list in the left-hand part of the title bar or, if the views are represented by tabs, by clicking the corresponding tab.
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.
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 Settings/Preferences Ctrl+Alt+S.
Title bar context menu
The context menu that appears by right-clicking the title bar or clicking , 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. | |
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 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). | |
