void nux::TextureArea::Set2DRotation

(

float

angle

)

Convenience function to set a 2D rotation when rendering the area.

The rotation is only used for rendering. It should not be used for something else.

Definition at line 145 of file TextureArea.cpp.

References nux::View::QueueDraw().

  {
    _2d_rotate.Rotate_z (angle);
    QueueDraw ();
  }

void nux::TextureArea::SetPaintLayer

(

AbstractPaintLayer *

layer

)

Set the paint layer of this area. The layer argument to this function is cloned by this object. It layer was allocated on the heap, it must be deleted later.

Parameters:

layer

A pointer to a concrete class that inherit from AbstractPaintLayer.

Definition at line 99 of file TextureArea.cpp.

References nux::View::QueueDraw().

  {
    NUX_SAFE_DELETE (m_PaintLayer);
    m_PaintLayer = layer->Clone();

    QueueDraw();
  }

void nux::TextureArea::SetTexture

(

BaseTexture *

texture

)

Render this area with a Texture. The reference count of the device texture which is cached by texture is increased by 1. It layer was allocated on the heap, it must be deleted later.

Parameters:

layer

A pointer to a BaseTexture class.

Definition at line 86 of file TextureArea.cpp.

References nux::TexCoordXForm::OFFSET_COORD, and nux::View::QueueDraw().

  {
    NUX_RETURN_IF_NULL(texture);
    NUX_SAFE_DELETE(m_PaintLayer);

    TexCoordXForm texxform;
    texxform.SetTexCoordType(TexCoordXForm::OFFSET_COORD);
    texxform.SetWrap(TEXWRAP_REPEAT, TEXWRAP_REPEAT);
    m_PaintLayer = new TextureLayer(texture->GetDeviceTexture(), texxform, color::White);

    QueueDraw();
  }
