Remarks

The root module must be exported with this contract:

[Export(ModulesService.RootModuleName, typeof(ILisrtModule))]
.

Constructors

ModuleTreeViewModel(IMenuBuilder, IModulesService, IEnumerable<Lazy<ILisrtModule, IRootModuleMetadata>>, IModuleTreeViewFilter)

Initializes a new instance of the ModuleTreeViewModel class.

[ImportingConstructor]
public ModuleTreeViewModel(IMenuBuilder menuBuilder, IModulesService modulesService, IEnumerable<Lazy<ILisrtModule, IRootModuleMetadata>> rootModules, IModuleTreeViewFilter moduleFilter)

Parameters

menuBuilder IMenuBuilder

Menu builder that builds the menu.

modulesService IModulesService

Service for the modules.

rootModules IEnumerable<Lazy<ILisrtModule, IRootModuleMetadata>>

Root modules.

moduleFilter IModuleTreeViewFilter

Filter for filtering modules.

Exceptions

ArgumentNullException

Thrown when menuBuilder or modulesService is null.

Properties

ContextMenuItems

Gets the menu items for the context menu in the Loehnert.Lisrt.Modules.Views.ModuleTreeView.

public IObservableCollection<MenuItemBase> ContextMenuItems { get; }

Property Value

IObservableCollection<MenuItemBase>

DisplayName

Gets the display name.

public override string DisplayName { get; }

Property Value

string

FirstGeneration

Gets the root modules.

public ObservableCollection<ModuleTreeItemViewModel> FirstGeneration { get; }

Property Value

ObservableCollection<ModuleTreeItemViewModel>

PreferredLocation

Gets the preferred PaneLocation for this Tool.

public override PaneLocation PreferredLocation { get; }

Property Value

PaneLocation

RootModuleIsNull

Gets a value indicating whether no root module is defined.

Methods

Fold(Func<int, ModuleTreeItemViewModel, bool?>)

Expands or folds the items of a module tree.

public void Fold(Func<int, ModuleTreeItemViewModel, bool?> shouldBeFolded)

Parameters

shouldBeFolded Func<int, ModuleTreeItemViewModel, bool?>

Function to determine whether ModuleTreeItemViewModel should be folded. The first argument is the generation (0 is the top level generation), the second argument is the module tree item view model. This function should return
true if the item should be folded
false if the item should be expanded
null if the IsExpanded value shouldn't be changed.

Examples

This example shows how fold all tree items, but not the top level items.

var moduleTree = (ModuleTreeViewModel)IoC.Get<IModuleTree>();
moduleTree.Fold((generation, vm) => generation >= 1);

This example shows how fold only the tree item named "Cavity1", all others are unchanged.

var moduleTree = (ModuleTreeViewModel)IoC.Get<IModuleTree>();
moduleTree.Fold((generation, vm) => vm.Module.Name == "Cavity1" ? (bool?)true : null);

Exceptions

ArgumentNullException

Thrown when shouldBeFolded is null.

GetSelectedModule()

Gets the selected ILisrtModule.

public ILisrtModule GetSelectedModule()

Returns

ILisrtModule

The selected ILisrtModule or null if no module is selected.
