[vtkusers] wxPlaneWidget on OSX

[ABE Hiroshi]

Dear All,

I modified the VTK wiki’s sample as is bottom of this mail to show the status of vtkPlaneWidget.
The output of “Print” method in the constructor is;

vtkPlaneWidget (0x7fea78d1e1d0)
  Debug: Off
  Modified Time: 2705
  Reference Count: 1
  Registered Events: (none)
  Current Renderer: 0x0
  Default Renderer: 0x0
  Enabled: 0
  Priority: 0.5
  Interactor: 0x0
  Key Press Activation: On
  Key Press Activation Value: i
  Prop3D: 0x0
  Input: 0x0
  Handle Size: 0.05
  Place Factor: 0.5
  Handle Property: 0x7fea78d4a2c0
  Selected Handle Property: 0x7fea78d4a470
  Plane Property: 0x7fea78d4a620
  Selected Plane Property: 0x7fea78d4a7d0
  Plane Representation: Wireframe
  Normal To X Axis: Off
  Normal To Y Axis: Off
  Normal To Z Axis: Off
  Resolution: 4
  Origin: (-0.5, -0.5, 0)
  Point 1: (0.5, -0.5, 0)
  Point 2: (-0.5, 0.5, 0)

and in the destructor;

vtkPlaneWidget (0x7fea78d1e1d0)
  Debug: Off
  Modified Time: 2806
  Reference Count: 0
  Registered Events: (none)
  Current Renderer: 0x7fea78f00160
  Default Renderer: 0x0
  Enabled: 1
  Priority: 0.5
  Interactor: 0x7fea78f00b40
  Key Press Activation: On
  Key Press Activation Value: i
  Prop3D: 0x0
  Input: 0x0
  Handle Size: 0.05
  Place Factor: 0.5
  Handle Property: 0x7fea78d4a2c0
  Selected Handle Property: 0x7fea78d4a470
  Plane Property: 0x7fea78d4a620
  Selected Plane Property: 0x7fea78d4a7d0
  Plane Representation: Wireframe
  Normal To X Axis: Off
  Normal To Y Axis: Off
  Normal To Z Axis: Off
  Resolution: 4
  Origin: (-0.562965, -0.555969, 0)
  Point 1: (nan, nan, nan)
  Point 2: (nan, nan, nan)

The Point 1 and 2 are changed to “nan”. The value (X,Y) in OnMouseMove is not strange as;
 ( 182, 172 ) 
 ( 180, 170 ) 
 ( 180, 169 ) 
 ( 177, 169 ) 
 ( 177, 167 ) 
 ( 175, 167 ) 
 ( 174, 166 ) 
 ( 174, 165 ) 
 ( 173, 165 ) 
 ( 218, 212 ) 
 ( 219, 213 ) 
 ( 221, 215 ) 
 ( 222, 217 ) 
 ( 224, 218 ) 
 ( 225, 221 ) 
 ( 226, 222 ) 
 ( 227, 224 ) 
 ( 229, 225 ) 
 ( 230, 225 ) 
 ( 232, 227 ) 
 ( 235, 229 ) 
 ( 237, 231 ) 
 ( 241, 234 ) 
 ( 244, 235 ) 
 ( 246, 236 ) 
 ( 247, 238 ) 
 ( 249, 238 ) 
 ( 250, 238 ) 
 ( 250, 239 ) 
 ( 252, 239 ) 
 ( 253, 241 ) 
 ( 253, 241 ) 
 ( 255, 241 ) 
 ( 255, 242 ) 
 ( 255, 244 ) 
 ( 256, 244 ) 
 ( 256, 244 ) 
 ( 258, 244 ) 

This is the result of my investigation on this.

Still I am looking for any suggestions on this.
Thank you.
