- Create returns ViewerSelector3d from StdSelect;
- ---Purpose: Constructs an empty 3D selector object.
-
- Create (theProj : Projector from Select3D) returns ViewerSelector3d from StdSelect;
- ---Purpose: Constructs a 3D selector object defined by the projector <theProj>.
-
- Convert (me : mutable; theSel : Selection from SelectMgr)
- is redefined static;
- ---Level: Public
- ---Purpose: Processes the projection of the sensitive primitives
- -- in the active view ; to be done before the selection action...
-
- Set (me : mutable; theProj : Projector from Select3D) is static;
- ---Purpose: Sets the new projector <theProj> to replace the one used at construction time.
-
- SetSensitivityMode (me : mutable;
- theMode : SensitivityMode from StdSelect) is static;
- ---Purpose: Sets the selection sensitivity mode. SM_WINDOW mode
- -- uses the specified pixel tolerance to compute the sensitivity
- -- value, SM_VIEW mode allows to define the sensitivity manually.
-
- SensitivityMode (me) returns SensitivityMode from StdSelect;
- ---C++: inline
- ---Purpose: Returns the selection sensitivity mode.
-
- SetPixelTolerance (me : mutable;
- theTolerance : Integer) is static;
- ---Purpose: Sets the pixel tolerance <theTolerance>.
-
- PixelTolerance (me) returns Integer from Standard;
- ---C++: inline
- ---Purpose: Returns the pixel tolerance.
-
- Pick (me : mutable; theXPix, theYPix : Integer;
- theView : View from V3d) is static;
- ---Level: Public
- ---Purpose: Picks the sensitive entity at the pixel coordinates of
- -- the mouse <theXPix> and <theYPix>. The selector looks for touched areas and owners.
-
- Pick (me : mutable; theXPMin, theYPMin, theXPMax, theYPMax : Integer; theView : View from V3d) is static;
- ---Purpose: Picks the sensitive entity according to the minimum
- -- and maximum pixel values <theXPMin>, <theYPMin>, <theXPMax>
- -- and <theYPMax> defining a 2D area for selection in the 3D view aView.
-
- Pick (me : mutable; thePolyline : Array1OfPnt2d from TColgp; theView : View from V3d) is static;
- ---Level: Public
- ---Purpose: pick action - input pixel values for polyline selection for selection.
