Detailed Description

Plot3D handles all the common features for plotting widgets - coordinate system, transformations, mouse/keyboard handling, labeling etc.. It contains some pure virtual functions and is, in so far, an abstract base class. The class provides interfaces for data handling and implements basic data controlled color allocation.

void setOrtho ( bool  val  )  [slot]

Set up ortogonal or perspective mode and updates widget

void enableMouse ( bool  val = true  )  [slot]

Enable mouse input.

The function has no effect if you derive from Plot3D and overrides the mouse Function too careless. In this case check first against mouseEnabled() in your version of mouseMoveEvent() and wheelEvent(). A more fine grained input control can be achieved by combining assignMouse() with enableMouse().

void disableMouse ( bool  val = true  )  [slot]

Disable mouse input.

See also:
enableMouse()

void enableKeyboard ( bool  val = true  )  [slot]

Enable keyboard input.

The function has no effect if you derive from Plot3D and overrides the keyboard Functions too careless. In this case check first against keyboardEnabled() in your version of keyPressEvent() A more fine grained input control can be achieved by combining assignKeyboard() with enableKeyboard().

void disableKeyboard ( bool  val = true  )  [slot]

Disable keyboard input.

See also:
enableKeyboard()

void enableLighting ( bool  val = true  )  [slot]

Turn Lighting on or off.

void disableLighting ( bool  val = true  )  [slot]

bool savePixmap ( QString const &  fileName,

Saves content to pixmap format

bool saveVector ( QString const &  fileName,
QString const &  format,
VectorWriter::TEXTMODE  text,
VectorWriter::SORTMODE  sortmode 
) [virtual, slot]

Saves content to vector format.

Deprecated:
Use Plot3D::save or IO::save instead.
Writes vector data supported by gl2ps. The corresponding format types are "EPS","PS"or "PDF". If zlib has been configured this will be extended by "EPS_GZ" and "PS_GZ". Beware: BSPSORT turns out to behave very slowly and memory consuming, especially in cases where many polygons appear. It is still more exact than SIMPLESORT.

bool save ( QString const &  fileName,
QString const &  format 
) [virtual, slot]

Saves content.

Saves content in one of the registered output formats. To modify the behaviour for more complex output handling use IO::outputHandler.
