UE4 Plugin 添加菜单和工具栏

UE4 Plugin 添加菜单和工具栏有两种方式：FExtender方式 和 UToolMenus方式

FExtender方式

添加工具栏

TSharedPtr<FExtender> MenuExtender = MakeShareable(new FExtender);
MenuExtender->AddToolBarExtension(ExtensionHook, EExtensionHook::After, PluginCommands,
//在AddDataTableEditorToolBarExtension 中设置SectionName
FToolBarExtensionDelegate::CreateRaw(this, &FMenuAndToolbarButtonModule::AddToolBarExtension));
EditorModule.GetToolBarExtensibilityManager()->AddExtender(MenuExtender);

添加在已有菜单

TSharedPtr<FExtender> MenuExtender = MakeShareable(new FExtender);
MenuExtender->AddMenuExtension(ExtensionHook, EExtensionHook::After, PluginCommands, FMenuExtensionDelegate::CreateRaw(this, &FMenuAndToolbarButtonModule::AddMenuExtension));
EditorModule.GetMenuExtensibilityManager()->AddExtender(MenuExtender);

添加在菜单栏

TSharedPtr<FExtender> MenuExtender = MakeShareable(new FExtender);
MenuExtender->AddMenuBarExtension(ExtensionHook, EExtensionHook::After, PluginCommands, FMenuBarExtensionDelegate::CreateRaw(this, &FMenuAndToolbarButtonModule::AddMenuBarExtension));
EditorModule.GetMenuExtensibilityManager()->AddExtender(MenuExtender);

EditorModule

FLevelEditorModule

FLevelEditorModule& LevelEditorModule = FModuleManager::LoadModuleChecked<FLevelEditorModule>("LevelEditor");

FDataTableEditorModule

FDataTableEditorModule& DataTableEditorModule = FModuleManager::LoadModuleChecked<FDataTableEditorModule>("DataTableEditor");

FBlueprintEditorModule

FBlueprintEditorModule& BlueprintEditorModule = FModuleManager::LoadModuleChecked<FBlueprintEditorModule>("BlueprintEditor");

UToolMenus方式

添加菜单

UToolMenu* ToolMenu = UToolMenus::Get()->ExtendMenu(InName);
{
	FToolMenuSection& Section = ToolMenu->FindOrAddSection(SectionName);
	Section.AddMenuEntryWithCommandList(FMenuAndToolbarButtonCommands::Get().PluginAction, PluginCommands);
}

添加工具栏

UToolMenu* ToolMenu = UToolMenus::Get()->ExtendMenu(InName);
{
	//添加工具栏
	FToolMenuEntry& Entry = Section.AddEntry(FToolMenuEntry::InitToolBarButton(FMenuAndToolbarButtonCommands::Get().PluginAction));
	Entry.SetCommandList(PluginCommands);
