CommandManager and CommandGroups

You can create native SolidWorks toolbars and menus using the ICommandManager and ICommandGroup interfaces.

NOTE: You can only create one CommandManager in an add-in application; however, multiple CommandGroups can exist in an add-in application. See SolidWorks Help for details about the CommandManager.

The CommandManager-style toolbars and menus let you:

  • Add toolbars to the SolidWorks CommandManager.

  • Drag your toolbar buttons to and from other API and native SolidWorks toolbars using the Tools, Customize dialog or ISldWorks::DragToolbarButton.

  • Create flyout toolbars and submenus.

Toolbar and menu setup are binded so that name, button, callback function, enable function, and add-in ID need only be specified once.

You cannot create a ICommandGroup with a toolbar, start SolidWorks, use the toolbar, close SolidWorks, add items to or remove items from the toolbar, and start SolidWorks. Therefore, during development, you must use the ID returned by ICommandGroup::ToolbarId to find the toolbar in the registry and remove the toolbar definition from the registry:

HKEY_CURRENT_USER\Software\SolidWorks\SolidWorks <version>\User Interface\Custom API Toolbars\<index>

HKEY_CURRENT_USER\Software\SolidWorks\SolidWorks <version>\User Interface\Toolbars

HKEY_CURRENT_USER\Software\SolidWorks\SolidWorks <version>\User Interface\Toolbars\PartTool

HKEY_CURRENT_USER\Software\SolidWorks\SolidWorks <version>\User Interface\Toolbars\AssemblyTool

HKEY_CURRENT_USER\Software\SolidWorks\SolidWorks <version>\User Interface\Toolbars\DrawingTool

You can then add and remove items from the toolbar.

For distribution purposes, assign the ICommandGroup a different user ID and do not activate the ICommandGroup using the former user ID. This is the ID of ICommandManager::CreateCommandGroup. You must keep track of the toolbar user IDs in use in each version of your add-in. The user ID and the GUID of the CoClass implementing ISwAddin are a unique pair.

To add commands:

  1. Create the ICommandManager using ISldWorks::GetCommandManager.

    You might want to declare this object as a class variable in your add-in so that it can be accessed from anywhere later.

  2. Create one or more top-level CommandGroups using ICommandManager::CreateCommandGroup or ICommandManager::AddContextMenu.

  3. Add bitmap files of the images of buttons to the CommandGroups using ICommandGroup::LargeIconList, ICommandGroup::SmallIconList, ICommandGroup::LargeMainIcon, and ICommandGroup::SmallMainIcon.

    You only add the bitmap files to the top-level group. These files provide the images of the buttons for all of the CommandGroups.

  4. Add commands to the CommandGroups using ICommandGroup::AddCommandItem2.

  5. Enable or disable toolbars or menus for specific CommandGroups using ICommandGroup::HasToolbar and ICommandGroup::HasMenu.

  6. Create context-sensitive menus using ICommandGroup::SelectType and ICommandGroup::CustomNames, if the selected object is a custom feature such as an attribute.

  7. Activate the top-level ICommandGroup using ICommandGroup::Activate.

To remove commands:

Use ICommandManager::RemoveCommandGroup for all CommandGroups created with ICommandManager::CreateCommandGroup and ICommandManager::AddContextMenu.
