UMVVMBlueprintViewExtension: - Added virtual OnPreviewContentChanged function. UMVVMWidgetBlueprintExtension_View: - Added GetAllBlueprintExtensions function. FBlueprintViewDesignerExtension: - New designer extension which overrides PreviewContentChanged and calls OnPreviewContentChanged on each UMVVMBlueprintViewExtension. FBlueprintViewDesignerExtensionFactory: - New designer extension factory which creates a FBlueprintViewDesignerExtension. UMVVMBlueprintViewExtension_PanelWidget: - Added NumDesignerPreviewEntries property. - Added static CreateDesignerPreviewEntries function which clears panels children then adds specified number of entries. - Overrides OnPreviewContentChanged which calls CreateDesignerPreviewEntries using the preview panel widget. FModelViewViewModelEditorModule: - Adds PanelWidgetExtensionFactory on module startup and removes on shutdown. FMVVMPanelWidgetExtensionCustomizationExtender: - Added "Num Designer Preview Entries" property row. - Calls UMVVMBlueprintViewExtension_PanelWidget::CreateDesignerPreviewEntries when entry class, slot template or "Num Designer Preview Entries" properties change. #jira UE-213718 [REVIEW] [at]zahra.nikbakht, [at]editor-ui-systems, [at]chris.gagnon #rb Vincent.Gauthier, zahra.nikbakht [CL 34032917 by graham lewis in ue5-main branch]
