the setLineThickness function has just been disappeared

stoune · May 9, 2023, 10:53am

In an inferior vtk.js version I could use functions from widgetState (vtkResliceCursorWidget):

const widget = vtkResliceCursorWidget.newInstance();
const widgetState = widget.getWidgetState();

// functions like:
widgetState.setOpacity(1);
widgetState.setSphereRadius(10);
widgetState.setLineThickness(1);
widgetState.setShowCenter(false);

But in the latest vtk.js version, those functions don’t work, I didn’t find an alternatif in the documentation, how can we do the same thing please?

Thank you

I can answer myself, as I have just the answer!

          ## From 25.x to 26
          
          
- **ResliceCursorWidget**: vtkResliceCursorContextRepresentation is deprecated and removed.
          Instead, a `vtkSphereHandleRepresentation` is used for `rotation` and `center` handles,
          and a `vtkLineHandleRepresenttion` is used for the axes. `rotateLineInView()` now
          takes an axis name (string, e.g. 'XinY') instead of a substate. `enableRotation`, `enableTranslation` and `keepOrthogonality` in widgetState are replaced by widget behavior accessors (e.g. `widgetInView.setEnableRotation(false)`). See RCW example.
            - `widgetState.setShowCenter()` is replaced by `widgetState.getCenterHandle.setVisible()`
            - `widgetState.setSphereRadius()` is replaced by `widgetState.getCenterHandle().setScale1()` and `widgetState.getStatesWithLabel('rotation').forEach((handle) => handle.setScale1())`
            - `widgetState.setLineThickness(t)` is replaced by `widgetState.getStatesWithLabel('line').forEach((handle) => handle.setScale3(t,t,t))`
            - `setScaleInPixels()` should now be set on the widget instead of the `widgetInView`.
            - `widgetState.setOpacity()` is replaced by `widgetState.getStatesWithLabel('handles').forEach((handle) => handle.setOpacity())`
          - SVGRepresentation and SVG widget support has been fully removed.
          
          
## From 24.x to 25
          
          
- **math**: For functions calling math functions for computations with matrices, the format must now be number[] or Matrix as defined in the typescript definitions.
          - All widgets handles inheriting from vtkHandleRepresentation now scale up automatically.
          
          
## From 23.x to 24
