Thank you for your reply. I have seen the attached example, but I need something different. After various tries, I have opted for the image control, though I am not 100% happy because symbols converted in images shows a "2" in the lower right side of the icon (to show that are 2D symbols). You can see (in the attached image) the difference between the big tile (obtained with CreateImgFromSymbol) and the smaller tiles (obtained with CreateImageControl). It is not what I wish to get from a "Modern Dialog", but I can live with it... For those that may be interested, since there are not plenty of examples around, here's the code to get the dialog above (kLib is the path to single files and folders whose name is, as symbols, in the vectorworks file at path symLib. PROCEDURE Example; const kLib = '/Applications/Vectorworks 2019 IT/Risorse/Elementi base/Mouldings - Models/Cornices'; symLib = '/Applications/Vectorworks 2019 IT/Risorse/Elementi base/Mouldings - Models/Cornices/MouldingsLib.vwx'; maxFolders = 1000; kTreeControlID = 4; kChosenSymbol = 5; kChosenText = 6; kBackwardBtn = 7; kForwardBtn = 8; kPages = 9; kFirstSymbol = 101; kSymbolWidth = 50; kRows = 6; kColumns = 7; TYPE menuItem = STRUCTURE voce: string; idx : integer; END; VAR dialog1 :INTEGER; result :INTEGER; widthInChars, heightInChars :INTEGER; root1, root2, child1, child2 :INTEGER; folders : array[0..maxFolders] of menuItem; buttons : array[0..maxFolders] of menuItem; c, r : integer; pagina, numeroPagine, numeroFiles: integer; function validProfileFile(name: string): boolean; begin validProfileFile := Pos('.cpf', name) > 0; end; procedure ricorsione(node: string; livello: integer; previous: integer); var i: integer; foldername: string; root: integer; begin i := 1; folderName := GetFilesInFolder(node, 1); WHILE (folderName <> '') DO BEGIN {writeln(livello, '.

I have tried also with the Image Control that responds to clicks but I did not get it to display the symbol image! I am doing this way: hImg := CreateImgFromSymbol('AM-530', 128,128, 0, 11, 9); if hImg <> nil then CreateImageControl(dialog1, 4, 200, 200, hImg); but, though the hImg is not nil, the symbol is not displayed. It is replaced by the Vectorworks icon. Below the code I am using to test. Of course, replace ''AM-530" with a symbol in your document. PROCEDURE Example; VAR dialog1 :INTEGER; int :INTEGER; hImg : handle; PROCEDURE dialog1_Handler(VAR item :LONGINT; data :LONGINT); BEGIN CASE item OF SetupDialogC: BEGIN SetItemClickable(dialog1, 4, TRUE); EnableItem(dialog1, 4, TRUE); END; 4 : BEGIN writeln('Strike!'); END; END; END; BEGIN writeln('Inizio'); dialog1 := CreateLayout('Example', TRUE, 'OK', 'Cancel'); {CreateSymbolDisplayControl(dialog1, 4, 'AM-530', 128, 128, 5, 0, 2);} hImg := CreateImgFromSymbol('AM-530', 128,128, 5, 0, 2); if hImg <> nil then CreateImageControl(dialog1, 4, 200, 200, hImg); SetFirstLayoutItem(dialog1, 4); int := RunLayoutDialog(dialog1, dialog1_Handler); END; RUN(Example); Here's the results: With the symbol control, the dialog is ok, but I cannot get clicks on the symbol… With the image control, I get clicks fired, but not the correct image 🤔

Hello, I am using the symbol display control in a dialog to show various symbols to choose from. I did not find a way to get user clicks on these controls, in the dialog handler. Is there a way or should I couple each symbol with a clickable control? Thank you for any advice, Paolo

Thank you for the answer. Is the list browser you mention, the so called “tree control”? I need a pulldown menu that acts like the class pulldown menu, but I have to populate it with folder names contained in nested folders. Currently I have to keep all folders together to have “one level” only for these pulldown menu limitations, but I’d like to have subfolders (and submenus)...

Hello, Is there a way to get a pulldown control in a VectorScript dialog that may have items with submenus, like the classes pulldown menu? I have explored functions the topic "Dialogs - Modern" of the VectorScript references, but did not find any clue. Yes, there is a tree control, but I have to remain in the size of a popup (more or less) for space needs. Any help? Thanks, Paolo

Hello, On request, I have prepared a quick video showing the usage of some of the parametric objects included in the Mouldings Plugins for Vectorworks 2019. The video is on YouTube and on the site: https://fitplot.it/vwplugins/mouldings.html Recap of what Mouldings plugins can do: The plugins set consists of 3 PIO (Moulding on 2D path, Moulding on 3D path, Frame) and 3 tools (2D path -> Moulding, NURBS -> Moulding 3D and Profile->File.cpf to create your own profiles to be used with the PIO). • Updated for VW2019 • More than 500 profiles subdivided in 12 categories • Best control on PIO parameters for an accurate customisation

I am happy to announce that my plugin set to create and manage mouldings is available, on request, for Vectorworks 2019. Please, if interested, contact me by the form on the plugin page here: https://fitplot.it/vwplugins/mouldings.html Recap: The plugins set consists of 3 PIO (Moulding on 2D path, Moulding on 3D path, Frame) and 3 tools (2D path -> Moulding, NURBS -> Moulding 3D and Profile->File.cpf to create your own profiles to be used with the PIO). • Updated for VW2019 • More than 500 profiles subdivided in 12 categories • Best control on PIO parameters for an accurate customisation

Solved! Julian code needed only some retouch, the idea was right! The correct procedure (at least it works for my purposes) is as follows: … resultStatus := GetCustomObjectInfo(parmName, parmHand, parmRecordHand, wallHand); IF (resultStatus = TRUE) AND (parmHand <> NIL) AND (parmRecordHand <> NIL) THEN BEGIN if GetObject(PFILESCELTO) <> NIL then begin symbol(PFILESCELTO, 0, 0, 0); h1 := LNewObj; h2 := GetCustomObjectProfileGroup(parmHand); IF h2 <> Nil THEN DelObject(h2); result := SetCustomObjectProfileGroup(parmHand, h1); end; … In this way the symbol is not visible in the PIO representation, but is embedded and thus, copy / paste, of the object will include the symbol itself.

Thank you, I have tried in the reset event (I am in an event driven plugin), but the symbol appears on the drawing… this is my code, PFILESCELTO is the symbol name, I have to check if it is on the drawing … parmName := 'BAD'; parmHand := nil; parmRecordHand := nil; wallHand := nil; primoPassaggio := TRUE; resultStatus := GetCustomObjectInfo(parmName, parmHand, parmRecordHand, wallHand); IF (resultStatus = TRUE) AND (parmHand <> NIL) AND (parmRecordHand <> NIL) THEN BEGIN if GetObject(PFILESCELTO) <> NIL then begin symbol(PFILESCELTO, 0, 0, 0); h1 := LNewObj; h2 := GetCustomObjectProfileGroup(parmHand); IF h2 <> Nil THEN DelObject(h2); IF h1 = NIL THEN result := SetCustomObjectProfileGroup(parmHand, h2); end; …

Hello experts, I have developed a plugin object that takes advantage of a particular symbol to get from it the polyline it contains. If I copy / paste this object on another drawing, the symbol is not copied, because it is not actually drawn in the object, it is just used to get the polyline. Is there a way to embed the symbol inside the object without the need to draw it? Thank you for any help.

Here's the script with the var passed as reference. It works only when you apply the trick s:=concat('', s); The result is a list of valid real numbers delimited by spaces, to be splitter later: 35.938 135.145 36.233 140.511 36.971 140.511 36.971 135.145 145 I'll try to port these in python. I do not know python, while I am an old Vectorscript developer. I hope python has a better array management (count, split etc.) as any modern language should. procedure trim; const testString = '<polygon points="35.938,135.145 36.233,140.511 36.971,140.511 36.971,135.145 "/>'; var r: dynarray[]of char; procedure trimNotInList(list: DYNARRAY[] OF CHAR; VAR s: dynarray[]of char); VAR i : INTEGER; t : dynarray[]of char; BEGIN t := s; i := 1; WHILE i <= Len(t) DO IF (Pos(Copy(t, i, 1), list) = 0) THEN Delete(t, i, 1) ELSE i := i + 1; s := t; END; procedure runOfSpacesIntoOne(var s:dynarray[]of char); var i:integer; temp: dynarray[] of char; begin s := Concat('',s); {pseudo reset} temp := ''; for i:=1 to len(s) do begin temp:=concat(temp, s[i]); if (i>1) then if (s[i]=' ') and (s[i-1]=' ') then temp := copy(temp, 1, len(temp)-1); end; s := temp; end; procedure trimSpaces(var s:dynarray[] of char); var i, ti, te:integer; begin s := Concat('',s); {pseudo reset} for i:=1 to len(s) do begin ti :=i; if s[i] <> ' ' then i := len(s); {esco dal for} end; for i:=len(s) downto 1 do begin te := i; if s[i] <> ' ' then i := 1; {esco dal for} end; s := copy(s, ti, te-ti+1); end; procedure replaceCommas(var s: dynarray[]of char); var i:integer; temp: string; begin s := Concat('',s); {pseudo reset} temp := ''; for i:=1 to len(s) do begin if s[i] = ',' then temp:=Concat(temp,' ') else if s[i] = '-' then temp:=Concat(temp,' -') else temp:=Concat(temp,s[i]) end; s := temp; end; {*********************** scanPolyPoints **********************} {return the substring between 'points="' and '"', I'll split these points later} procedure scanPolyPoints(parameter: string; line: DYNARRAY[] OF CHAR; var r:DYNARRAY[] OF CHAR); var index1, index2: integer; temp: DYNARRAY[] OF CHAR; begin index1 := Pos(parameter, line)+1+len(parameter); temp := copy(line, index1, len(line)-index1); index2 := Pos('"', temp); temp := copy(temp, 1, index2-1); temp := concat('', temp); trimNotInList('0123456789+-,. ',temp); replaceCommas(temp); runOfSpacesIntoOne(temp); r := temp; trimSpaces(r); end; begin r:=teststring; scanPolyPoints(' points=', teststring, r); writeln(r); end; run(trim);

Ok, I'll try to port to python all the project. However, I've tried to reset the variable as suggested s := Concat('',s); and it works!

Give a try with "Moulding plugins", a set of tools I developed sometime ago for the Vectordepot Market (now shut off). Start here: https://fitplot.it/vwplugins/mouldings.html The tools are all updated for Vectorworks 2018. I have decided to share these plugins free of charge, but if you find it useful in your work, well, a little PayPal contribution is welcome.

I am proud to announce that some of my plugins and scripts (previously hosted on Vectordepot) are made available for download here: https://fitplot.it/vwplugins/ These are a few items developed by me (Paolo Marcuccetti) in the past years, updated and working with VW2018. I give these softwares free for download and usage, not for distribution. If you find these softwares useful in your work, please consider a little paypal donation. You'll find instructions on site. Contributions will be used to keep the site updated, to bring in new contents and to give any technical assistance. Paolo Marcuccetti
