Oplot, Props and Octave supports handle graphics.

[Ole Jacob Hagen]

Oplot, Props and Octave works pretty good with eachother...I think.... :-)

Oplot consists of a transport-channel, visualisation, and octave-module.
This octave-module forks Oplot, and sends data to Oplot by using the 
transport-module. On Linux unix domain sockets is used.

This octave-module can be easily modified to also implement tcp/ip or 
pipes.
The Oplot-application is able to send back data to Octave, by using the 
same transport-module as the octave-module. 

Usage of Props-code only exists in Oplot, and not in Octave.
The octave-module can transmit and receive datatypes such as: struct, 
matrix, mxnx3 matrices, numbers, strings.
Support of new datatypes can be easily added in oplotcom.cc i 
$(OPLOT)/src/octave. Remember duplex support. :-)

Props is an independent library in Oplot, where callback and 
initiatiation are handled.
Oplot is only using Props-library, and is setting callbacks to 
determined classes.

Callbackinterface-class in Props is a parent-class, and is inherited by 
RootCallbackInterface and FigureCallbackInterface.

RootCallbackInterface is used and inherited by OpFigureManager-class in 
Oplot.
RootCallbackInterface is initialised by the following line in 
OpFigureManager's ctor:

   Root::instance().setRootCallbackInterface(*this*);


FigureCallbackInterface is used and inherited by OpFigureWindow-class in 
Oplot.
FigureCallbackInterface is initialised by a the following line in 
OpFigureManager::new_figure(Props::Figure* fig):

int
OpFigureManager::new_figure( Figure* fig) {

   OpFigureWindow* fw = *new* OpFigureWindow(fig, *this*);
   QPoint pos(420,500);
   QSize sz = *this*->parentWidget(*true*)->size();
   fig->setCallbackInterface(fw);
   fw->setPosition(pos,sz);
   *this*->addFigureWindow(fw, (int) fig->getHandle());
   *return* 0;
}


Axes-Callbacks, Line-Callbacks, Image-Callbacks, Text-Callbacks are 
initialised in a similar fashion:

Axes-Callbacks:

int
OpFigureWindow::new_axes( Axes* ax) {
   OpAxesObject *opax = *new* OpAxesObject(ax, *this*,m_axNum);
   ax->setCallbackInterface(opax);
   m_axNum++;
   *return* 0;
}


Initialisation of callbacks and creation of new child of Axes-object 
such as Text, Line, Image is created like this:
Guess how Surface, Patch and Rectangle-object should be initialised?

int
OpAxesObject::new_child( Object* p,  Object* c) {
   const std::string* child = c->get_string("Type");
   *if*(*child == "Text") {
       Text *text = *static_cast*<Text *>(c);
       OpTextObject *textObject = *new* OpTextObject(text, *this*);
       text->setCallbackInterface(textObject);
       m_textComponents.push_back(textObject);
   } *else* *if*(*child == "Line") {
       Line* line = *static_cast*<Line*>(c);
       OpLineObject *lineobject = *new* OpLineObject(line, *this*);
       line->setCallbackInterface(lineobject);
       }
       m_visComponents.push_back(lineobject);
   } *else* *if*( *child == "Image") {
       Image *image = *static_cast*<Image *>(c);
       OpImageObject *imageObject = *new* OpImageObject(image, *this*);
       image->setCallbackInterface(imageObject);
       m_visComponents.push_back(imageObject);
   }
   *return* 0;
}


I present to you Oplot with Props and Octave.
e.g root = get(0); root.Clipping <enter> gives "on" as output.

Setting properties such as set(handle_value, 'property_name', 
property_value) is of course possible.
Getting properties with get(handle_value, 'property_name') returns the 
property_value that is contained in property_name in handle_value...


Available properties and handle graphics objects supported by Props, and 
Oplot are presented at the bottom of this email.


Cheers,


Ole J.
