Function Documentation

static int drvKeyCrtl (  Ihandle *  dg, int  key )  [static]

Callback function for keyboard event (see IUP documentation). This function takes an appropriate action according to the given key that was pressed by the user and passed as a parameter. Parameters: dg  - handle to IUP main dialog object (in) key  - pressed key identifier (in) Returns: IUP_DEFAULT value or IUP_CLOSE value (if key is CONTROL+Q) Definition at line 291 of file drv.cpp. References doing_help, drvOpenFile(), Prj::Fit(), Prj::Info(), Prj::ManipMode(), Prj::NavigMode(), Prj::OpenModel(), Prj::Ortho(), Otopmsg, Prj::Persp(), Prj::ProjX(), Prj::ProjY(), Prj::ProjZ(), Prj::Quit(), Prj::ResetView(), Prj::vglcanvas, Prj::ZbufferSnapShot(), and Prj::ZoomMode(). Referenced by main().

static void drvMouseBt (  int  bt, int  mode, float  x, float  y, void *  data )  [static]

Callback function for mouse button event on canvas (see VGL documentation). Parameters: bt  - button identifier (in) mode  - mode (button pressed or released) (in) x,y  - mouse raster position (left-top origin) (in) data  - dummy data (not used) (in) Definition at line 202 of file drv.cpp. References cv_height, cv_width, doing_help, Prj::GetHeightFac(), Oheightval, Otopmsg, Prj::Raster2WorldXY(), and Prj::SelectPrm(). Referenced by main().

static void drvMouseMv (  int  bt, float  x, float  y, void *  data )  [static]

Callback function for mouse movement event on canvas (see VGL documentation). In this implementation it does nothing. Parameters: bt  - button identifier (in) x,y  - mouse raster position (left-top origin) (in) data  - dummy data (not used) (in) Definition at line 247 of file drv.cpp. Referenced by main().

static FILE* drvOpenFile (  char *  mode  )  [static]

This function prompts the user for a file name and opens the file. Parameters: mode  - reading ("r") or writing ("w") mode (in) Returns: Pointer to opened file Definition at line 88 of file drv.cpp. References file_name. Referenced by drvKeyCrtl().

static void drvRedisplay (  void *  h  )  [static]

Callback function for canvas redisplay event (see VGL documentation). It redisplays the model or the help message on the canvas. Parameters: h  - dummy handle (not used) (in) Definition at line 175 of file drv.cpp. References doing_help, Prm::First(), Prj::Help(), Otopmsg, and Prj::Redisplay(). Referenced by main().

static void drvResize (  int  width, int  height, void *  h )  [static]

Callback function for canvas resize event (see VGL documentation). It changes the visualization parameters according to the given canvas sizes. Parameters: width  - new canvas width (in) height  - new canvas height (in) h  - dummy handle (not used) (in) Definition at line 159 of file drv.cpp. References cv_height, cv_width, Prj::Odatascreen, and Prj::Resize(). Referenced by main().

static int drvSetHeightFac (  Ihandle *  val, double  fac )  [static]

Callback function for primitive height valuator event (see IUP documentation). This function sets the new value for the current selected primitive height according to the given height factor. Parameters: val  - handle to IUP primitive height valuator (in) fac  - new valuator factor value (in) Returns: IUP_DEFAULT value Definition at line 272 of file drv.cpp. References Prj::SetHeightFac(). Referenced by main().

int main (  int  argc, char *  argv[] )

This is the main driver of the program. The program launches an user interface window on the screen and waits for an user action. Parameters: argc  - number of arguments (not used) (in) argv  - list of string arguments (not used) (in) Returns: Program status: success (0) or failure (1) Definition at line 403 of file drv.cpp. References drvKeyCrtl(), drvMouseBt(), drvMouseMv(), drvRedisplay(), drvResize(), drvSetHeightFac(), Prj::Init(), Prj::Odatascreen, Oheightval, Omain, Otopmsg, and Prj::vglcanvas.
