I also suspected that there might be something wrong with the user writes but there isn't - I tried running the application/sample as a root user and I get the same error message; I also tried saving the file to a directory that isn't writable and then I get a completely different error message (saying that it can't open the requested file for writing). As I said, when I try to save a CVG file to a writable directory, it creates a file but it's completely empty, zero bytes in size, and this line here with which I'm trying to write the file: bool success = a2dDocviewGlobals->GetDocviewCommandProcessor()->FileSaveAs(title); returns true (i.e. success equals to true), meaning everything went ok and the file is written... >> > > Here in wire.cpp ? > > a2dCanvasDocument *doc = m_preview->GetCanvasDocument(); > a2dCanvasObject *obj = NULL; > doc->DeleteContents(); > > It is a document that is not the canvas to where you drag to.

Is there any way to merge several graphical primitives (e.g. rectangles, circles, arcs, etc.) into one bigger block or a polygon? For instance, I want to merge an arc and a rectangle so that the merged element behaves as a unique polygon, one with which I can manipulate as a separate unit (e.g. fill it with color and similar). That would enable me to create more complex shapes without the need to display their respective borders and similar. 2. I'm quite well acquainted with the wxWidgets' event/notification architecture and although I see the events in the wxArt2D are similar, I'm still having trouble with finding the list of events which are being transmitted by the controls. For instance, I use the a2dDragNewTool to drag new objects onto my canvas and I'd like to be notified every time a new object is released onto the canvas (that is, a left click on the canvas has occurred while using the a2dDragNewTool); is there any event that is being transmitted when that occurs? Should I override the OnMouseEvent and send an event by myself? Something else? :) Thank you again for your time and answers :) Kind regards, Ioannes -- Infinite diversity in infinite combinations ------------------------------------------------------------------------------ Download Intel® Parallel Studio Eval Try the new software tools for yourself.
