bool vtkControlPointsItem::IsOverPoint | ( | double * | pos, |
vtkIdType | pointId | ||

Returns true if pos is above the pointId point, false otherwise. It uses the size of the drawn point. To search what point is under the pos, use the more efficient
vtkIdType vtkControlPointsItem::GetControlPointId | ( | double * | pos | ) |
Returns the id of the control point exactly matching pos, -1 if not found.
void vtkControlPointsItem::GetControlPointsIds | ( | vtkIdTypeArray * | ids, |

|
virtual |
Controls whether or not control points are drawn (true) or clicked and moved (false). False by default.
|
virtual |
If DrawPoints is false, SwitchPoints controls the behavior when a control point is dragged past another point. The crossed point becomes current (true) or the current point is blocked/stopped (false). False by default.

pure virtual |
Add a point to the function. Returns the index of the point (0 based), or -1 on error. Subclasses should reimplement this function to do the actual work.
Implemented in vtkCompositeControlPointsItem, vtkColorTransferControlPointsItem, and vtkPiecewiseControlPointsItem.
|
pure virtual |
Remove a point of the function. Returns the index of the point (0 based), or -1 on error. Subclasses should reimplement this function to do the actual work.

Remove a point give its id. It is a utility function that internally call the virtual method RemovePoint(double*) and return its result.
|

void vtkControlPointsItem::MovePoints | ( | const vtkVector2f & | translation, |
vtkIdTypeArray * | pointIds | ||
) |
Move the points referred by pointIds by a given translation. The new positions won't be outside the bounds. MovePoints is typically called with GetControlPointsIds() or GetSelection(). Warning: if you pass this->GetSelection(), the array is deleted after each individual point move. Increase the reference count of the array. See also MoveAllPoints()
void vtkControlPointsItem::MovePoints | ( | const vtkVector2f & | translation, |
bool | dontMoveFirstAndLast = false |
||
) |
Utility function to move all the control points of the given translation If dontMoveFirstAndLast is true, then the first and last points won't be moved.
void vtkControlPointsItem::SpreadPoints | ( | float | factor, |
vtkIdTypeArray * | pointIds | ||
) |
Spread the points referred by pointIds If factor > 0, points are moved away from each other. If factor < 0, points are moved closer to each other SpreadPoints is typically called with GetControlPointsIds() or GetSelection(). Warning: if you pass this->GetSelection(), the array is deleted after each individual point move. Increase the reference count of the array.
void vtkControlPointsItem::SpreadPoints | ( | float | factor, |
bool | dontSpreadFirstAndLast = false |
||
) |
Utility function to spread all the control points of a given factor If dontSpreadFirstAndLast is true, then the first and last points won't be spread.

|
virtual |
Depending on the control points item, the brush might not be taken into account.
void vtkControlPointsItem::ResetBounds | ( | ) |
Recompute the bounds next time they are requested. You shouldn't have to call it but it is provided for rare cases.
