:Mask format change in VW2016 on a Windows 7 machine
On OSX, the defaultFolder has to be just the folder, but on OS9 or on Windows, it can include a filename. Either way, if a filename is present, the file does not get selected in the dialog, so don't bother casing this for platforms -- just make sure that defaultFolder just has the name of a folder.
:Python mask example: '*.txt' if VW-Version < 2016 else 'txt'


On OSX, GetFileN expects a fully qualified name, using foreslashes, such as '/Applications/VectorWorks'.

Description

Returns the fully-qualified pathname of the selected file. 

FUNCTION GetFileN(
          title           :STRING;
          defaultFolder   :STRING;
          mask            :STRING;
          VAR fileName    :STRING) : BOOLEAN;
def vs.GetFileN(title, defaultFolder, mask):
    return (BOOLEAN, fileName)

Parameters

title STRING
defaultFolder STRING
mask STRING
fileName STRING

Remarks

(Orso 2017.01.22): Prompts for selection of a file of type "mask". The parameter "defaultFolder", if not empty, must be a posix path (with slashes). A HFS path (with colons) to the default folders can be obtained with VS:GetFolderPath, you will need to use VS:ConvertHSF2PosixPath for converting it into posix. Assigns the found path to var "fileName". Mask is case sensitive. The returned path is posix.

  • mask = '*.vwx' allows selection of files of type .vwx
  • mask = '****' allows selection of any kind of files
  • mask = 'vwx;txt' allows range of selection (from Pat Stanford on the VS list)


The GetFileN uses the SDK interface IFileChooserDialog

VCOM:Working with File/Folder Choose Dialogs

the ‘mask’ parameter goes as input to fileChooser->SetDefaultExtension(mask);

VCOM:VectorWorks:Filing:IFileChooserDialog::SetDefaultExtension

(MaKro, 2016.10.18):

Mask format change in VW2016 on a Windows 7 machine
Python mask example: '*.txt' if VW-Version < 2016 else 'txt'

Example

PROCEDURE Example;

VAR
	fileName, title :STRING; 
	defaultFolder :STRING; 
	mask :STRING; 
	
BEGIN
	title := 'Select the object library file...';
	defaultFolder := '';
	mask := '*.vwx';
	fileName := 'Drafting Tools.vwx';

	IF GetFileN(title, defaultFolder, mask, fileName) THEN 
		AlrtDialog(fileName);
	END;
RUN(Example);
