Member Function Documentation
| static int vtkOpenGLContextBufferId::IsTypeOf | ( | const char * | name | ) | [static] |
Return 1 if this class type is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.
Reimplemented from vtkAbstractContextBufferId.
| virtual int vtkOpenGLContextBufferId::IsA | ( | const char * | name | ) | [virtual] |
Return 1 if this class is the same type of (or a subclass of) the named class. Returns 0 otherwise. This method works in combination with vtkTypeMacro found in vtkSetGet.h.
Reimplemented from vtkAbstractContextBufferId.
| static vtkOpenGLContextBufferId* vtkOpenGLContextBufferId::SafeDownCast | ( | vtkObjectBase * | o | ) | [static] |
Reimplemented from vtkAbstractContextBufferId.
| virtual vtkObjectBase* vtkOpenGLContextBufferId::NewInstanceInternal | ( | ) | const [protected, virtual] |
Reimplemented from vtkAbstractContextBufferId.
Reimplemented from vtkAbstractContextBufferId.
| virtual void vtkOpenGLContextBufferId::PrintSelf | ( | ostream & | os, |
| vtkIndent | indent | ||
| ) | [virtual] |
Methods invoked by print to print information about the object including superclasses. Typically not called by the user (use Print() instead) but used in the hierarchical print process to combine the output of several classes.
Reimplemented from vtkAbstractContextBufferId.
| static vtkOpenGLContextBufferId* vtkOpenGLContextBufferId::New | ( | ) | [static] |
Creates a 2D Painter object.
Reimplemented from vtkAbstractContextBufferId.
| virtual void vtkOpenGLContextBufferId::ReleaseGraphicsResources | ( | ) | [virtual] |
Release any graphics resources that are being consumed by this object.
Reimplemented from vtkAbstractContextBufferId.
| virtual void vtkOpenGLContextBufferId::SetContext | ( | vtkRenderWindow * | context | ) | [virtual] |
Set/Get the OpenGL context owning the texture object resource.
Implements vtkAbstractContextBufferId.
| virtual vtkRenderWindow* vtkOpenGLContextBufferId::GetContext | ( | ) | [virtual] |
Set/Get the OpenGL context owning the texture object resource.
Implements vtkAbstractContextBufferId.
| virtual bool vtkOpenGLContextBufferId::IsSupported | ( | ) | [virtual] |
Returns if the context supports the required extensions.
- Precondition:
- context_is_set: this->GetContext()!=0
Implements vtkAbstractContextBufferId.
| virtual void vtkOpenGLContextBufferId::Allocate | ( | ) | [virtual] |
Allocate the memory for at least Width*Height elements.
- Precondition:
- positive_width: GetWidth()>0
- positive_height: GetHeight()>0
- context_is_set: this->GetContext()!=0
Implements vtkAbstractContextBufferId.
| virtual bool vtkOpenGLContextBufferId::IsAllocated | ( | ) | const [virtual] |
Tell if the buffer has been allocated.
Implements vtkAbstractContextBufferId.
| virtual void vtkOpenGLContextBufferId::SetValues | ( | int | srcXmin, |
| int | srcYmin | ||
| ) | [virtual] |
Copy the contents of the current read buffer to the internal texture starting at lower left corner of the framebuffer (srcXmin,srcYmin).
- Precondition:
- is_allocated: this->IsAllocated()
Implements vtkAbstractContextBufferId.
| virtual vtkIdType vtkOpenGLContextBufferId::GetPickedItem | ( | int | x, |
| int | y | ||
| ) | [virtual] |
Return item under abscissa x and ordinate y. Abscissa go from left to right. Ordinate go from bottom to top. The return value is -1 if there is no item.
- Precondition:
- is_allocated: IsAllocated()
- Postcondition:
- valid_result: result>=-1
