HDK: File chooser - only certain extensions ?

[nicholas_yue]

I would like my file chooser in my C++ SOP plugin to only show up certain file extensions.

What is the recommended way ?

static const char* theDsFile = R"THEDSFILE(
{
    name        parameters
	parm {
				name    "shpfile"      // Internal parameter name
				label   "SHP File" // Descriptive parameter name for user interface
				type    file
				default { "" }     // Default for this parameter on new nodes
				parmtag { "autoscope" "0000000000000000" }
				parmtag { "filechooser_pattern" "*.shp" }
				parmtag { "import_token" "shp_file" }
			}
}
)THEDSFILE";

most important is "parmtag { "filechooser_pattern" "*.shp" }"

you can change *.shp to any format you want
