Hi Folks,

I've seen some python code on how to turn some viewport filters on/off, but the c++ was a little confusing to me (maybe the syntax?). Is someone in the know able to clarify the following:

1. There's DOCUMENT_SELECTIONFILTER and DOCUMENTFILTER_ flags, which is used for turning off, say viewport polygons, and how is it done? Below is one of the variations I've tried:

BaseDocument *doc = GetActiveDocument();
BaseContainer bc = doc->GetData(DOCUMENTSETTINGS_DOCUMENT);
LONG Filter = bc.GetLong(DOCUMENT_SELECTIONFILTER);
 
bc.SetLong(DISPLAYFILTER_POLYGON,...);  // <--- does something go here?
doc->SetData(DOCUMENTSETTINGS_DOCUMENT,bc);

2. Second to the above, can this be done on a per-viewport basis? I've tried the GetBaseDrawCount() to try and find a window count, but it always returns the same value (which is 4 for me) which leaves me unsure on how to get a viewport on an individual basis (if possible).

Cheers,

WP

What you've got there is code for the SelectionFilter option. Not the DisplayView option.
This is how to enable/disable the DV polygon option.
AFAIK. This option can't be different for multiple windows.

    BaseDraw *bd = doc->GetActiveBaseDraw();  
  
  //Use "TRUE" or "FALSE" to turn it on/off  
  bd->SetParameter(DescLevel(BASEDRAW_DISPLAYFILTER_POLYGON), FALSE, DESCFLAGS_SET_0);

Since you've said you don't understand that code you posted.
Here's also examples of how to use it to enable/disable the SelectionFilter's polygon option.
The SelectionFilter uses bitwise operators to enable/disable them.

//This code Turns the Select->SelectionFilter menu polygon filter option OFF  
//The option found in the Select->Selection Filter menu  
  
  //Gets the document's container which includes the selection filter bit mask  
  BaseContainer bc = doc->GetData(DOCUMENTSETTINGS_DOCUMENT);  
  
  LONG sf = bc.GetLong(DOCUMENT_SELECTIONFILTER);   //Get the filter bit mask  
   
  if(!(sf & SELECTIONFILTERBIT_POLYGON))            //If the polygon option is enabled  
  {        
      LONG f = sf | SELECTIONFILTERBIT_POLYGON;     //Turns the polygon filter option off using the bitwise switching off code  
      bc.SetLong(DOCUMENT_SELECTIONFILTER, f);  
  }  
  doc->SetData(DOCUMENTSETTINGS_DOCUMENT, bc);  
  
  EventAdd();  
  
  
  
  
//This code Turns the Select->SelectionFilter menu polygon filter option ON  
//The option found in the Select->Selection Filter menu  
  
  //Gets the document's container which includes the selection filter bit mask  
  BaseContainer bc = doc->GetData(DOCUMENTSETTINGS_DOCUMENT);  
  
  LONG sf = bc.GetLong(DOCUMENT_SELECTIONFILTER);  //Get the filter bit mask  
   
  if(sf & SELECTIONFILTERBIT_POLYGON)             //If the polygon option is enabled  
  {       
      LONG f = sf &~ SELECTIONFILTERBIT_POLYGON;   //Turns the polygon filter option on using the bitwise switching ON code  
      bc.SetLong(DOCUMENT_SELECTIONFILTER, f);  
  }  
  doc->SetData(DOCUMENTSETTINGS_DOCUMENT, bc);  
  
  EventAdd();

Hi Scott,
thanks for the above, I seem to have the viewport filters under control now. I was all over the place with them!

The selection ones don't seem to be doing much for me - I'll need to have a closer look at them.
