NXOpen::BlockStyler Namespace Reference (C++)

Documented purpose: "Provides classes and interfaces for Block Styler." 67 classes. This is the direct API-side counterpart to the Block UI Styler GUI tool (Tools > Block UI Styler in NX; also documented from the GUI/.bx-file-authoring side elsewhere in this knowledge base under blockstyler/). Every widget you can drag onto a canvas in the Block UI Styler editor corresponds 1:1 to a class here — the .dlx/generated code that the Styler produces literally instantiates these classes at runtime.

Base classes

Class	Description
UIBlock	Represents a UI Block. Created in NX6.0.0. This is the common base class for every block type below — the polymorphic type used when code needs to treat any block generically (e.g. enabling/disabling, show/hide, generic event callbacks).
BlockDialog	Represents a Dialog. Created in NX6.0.0. The top-level dialog object a .bx-authored UI styler dialog compiles down to — the root container that owns and lays out all child UIBlocks.
CompositeBlock	A composite block is a block that contains other blocks. Created in NX6.0.0. The base for any container/group-like block (see Group, Table, ScrolledWindow, TabControl).
DialogTester	Represents Block Styler Dialog tester class that contains testing tools for Block Styler Dialogs. To obtain an instance of this class, refer to NXOpen::UI. Created in NX2206.0.0.
MessageBoxTester	Testing helper counterpart for message-box-driven dialogs (pairs with DialogTester).
TestStepSequence	Represents a scripted sequence of test steps, used together with DialogTester/MessageBoxTester for automated UI testing of Block Styler dialogs.

Input / value blocks

Class	Description
Button	Represents a button. Created in NX8.5.0.
Toggle	Checkbox-style boolean toggle block.
StringBlock	Single-line string/text input block.
MultilineString	Multi-line text input block.
IntegerBlock	Integer-valued numeric input block.
DoubleBlock	Represents a Double block. Created in NX8.5.0 — floating-point numeric input.
Enumeration	Enumerated/dropdown-style choice block.
ChooseExpression	Block for choosing/entering an NX Expression.
ExpressionBlock	Block bound directly to an NX Expression value.

Selection blocks (geometry/objects)

Class	Description
SelectObject	Represents a Select Object block. Created in NX8.5.0 — generic object selection.
SelectElement	Select a specific element (more constrained than SelectObject).
SelectFeature	Select a feature specifically.
SelectFacetRegion	Select a facet region (faceted/mesh body geometry).
SelectNode	Select a node (e.g. CAE mesh node).
SelectPartFromList	Select a part from a list (assembly context).
BodyCollector	Collector block for selecting one or more bodies.
CurveCollector	Collector block for selecting one or more curves.
FaceCollector	Collector block for selecting one or more faces.

Geometry-specifying blocks

Class	Description
SpecifyPoint	Represents a Specify Point block. Created in NX8.5.0 — the standard "point constructor" widget.
SpecifyVector	Vector-constructor widget.
SpecifyPlane	Plane-constructor widget.
SpecifyAxis	Axis-constructor widget.
SpecifyCSYS	Coordinate-system-constructor widget.
SpecifyOrientation	Orientation-constructor widget.
SpecifyLocation	Location-constructor widget.
ReverseDirection	Small widget/button pairing with vector/direction blocks to flip direction.
Microposition	Fine-positioning helper widget.

Dimension blocks

LinearDimension, AngularDimension, RadiusDimension, OnPathDimension — each represents the corresponding interactive dimension-entry widget (used when a Block Styler dialog needs to let the user set a driving dimension value directly in the graphics window).

Layout / container blocks

Class	Description
Group	Represents a Group Block. Created in NX8.5.0 — a labeled/bordered grouping container.
Table	Represents a Table layout. Created in NX8.5.0 — grid/table layout container.
TabControl	Tabbed-page container.
ScrolledWindow	Scrollable container.
Separator	Visual separator/divider.
Label	Static text label.
DrawingArea	Custom-drawable canvas area block.

List / tree blocks

Class	Description
ListBox	Represents a ListBox block. Created in NX6.0.0.
SetList	Dual-list "set" builder widget (available/selected list pairing).
Tree	Hierarchical tree control.
TreeListMenu	Represents a menu class utilized by BlockStyler::Tree.
Node	A single node within a Tree.
Explorer	Explorer/browser-style hierarchical widget.
IntegerTable / DoubleTable	Typed tabular data widgets for integer/double columns.
PropertyList	Property-sheet-style list widget.

Color / appearance blocks

ObjectColorPicker, RGBColorPicker, LineColorFontWidth, LineFont, LineWidth, TextColorFontWidth — pickers for object color, direct RGB color, and line/text style (font, width) — mirroring NX's standard color/line-style dialogs as embeddable blocks.

Sketch/section-related blocks

SectionBuilder, SuperSection, SuperPoint, OrientXpress — blocks for building/editing sketch sections and orientation, used in dialogs that need inline section authoring (e.g. sweep/loft-style feature dialogs).

Higher-level composite

Class	Description
Wizard	Represents a Wizard block. Created in NX7.5.0 — a multi-page wizard-style dialog flow built from Block Styler pages.
FileSelection / FolderSelection	File/folder browse-and-select widgets.

Cross-reference: how this maps to the Block UI Styler GUI tool

The Block UI Styler editor (documented in this knowledge base's blockstyler/ folder from the tool-usage side) lets a developer visually compose a .bx dialog file by dragging these exact block types onto a canvas, then generates NX Open source (C++/.NET/Java/Python — the generated code differs per language but instantiates the equivalent class from each language's BlockStyler namespace). The class-level catalog above is therefore the ground truth for "what a given Block UI Styler widget actually is" when reading or hand-editing generated dialog code — e.g. a Styler canvas item labeled "Specify Point" instantiates NXOpen::BlockStyler::SpecifyPoint, a "List Box" instantiates NXOpen::BlockStyler::ListBox, and the containing dialog itself is always a NXOpen::BlockStyler::BlockDialog.
