Parameters:
vmxt  Add callback to tool
func  Callback function
udata  User data passed to func
reason  Reason set flags to get callbacks on

void MxtCallActivateCallback (  MXTHANDLE  mxt  ) 
 

Call "activate" callback for specified tool.

Parameters:
mxt  Tool handle

int MxtCallbackAddExt (  MXTHANDLE  vmxt,
McbCallbackFunc  func,
void *  udata,
UINT32  reason,
INT8  priority
) 
 

Add callback to tool with position determined by priority.

Parameters:
vmxt  Add callback to tool
func  Callback function
udata  User data passed to func
reason  Reason set flags to get callbacks on

void MxtCallChangeCallback (  MXTHANDLE  mxt,
UINT32  reason
) 
 

Call "change" callback for specified tool.

Parameters:
mxt  Tool handle
reason  Callback reason

void MxtClearPosition (  MXTHANDLE  mxt  ) 
 

Clear tool position (erasing tool).

This function undraws the tool then clears the tool information. Useful in activate callbacks to simulate adding elements.

Parameters:
mxt  Handle returned by MxtCreate()

MXTHANDLE MxtCreate (  Widget  pwidget,
MXTHANDLE(*  CreateFunc)(UINT32, void *),
UINT32  flags
) 
 

Create new tool instance.

This function creates a tool handle by calling the appropriate tool create function. It also sets up the default tool position which will be a clear tool (no info). Neither the tool create function nor this function will create the dialog. Any setup of the tool dialog must be done before MxtManage() is called because MxtManage() sets up the dialog. NOTE: Call MxtSetValues() to setup default tool information. List of flags to pass in this function (see MxtSetFlags()).

  • MxtFLAG_EnableManual
  • MxtFLAG_EnableDialog
  • MxtFLAG_EnableXYDig
  • MxtFLAG_EnableSnapGrid Any tool specific flags dealing with dialog management. Eg:
  • MxEPOLYLINE_NoEditZValue
  • MxEPOLYLINE_NoClosePolyB
Parameters:
pwidget  Drawing Area widget
flags  Function to create specific tool MxtFLAG... flags
