DELPHI AREA Forum

I use Simple Graph v2.71
Changes in dimension of the TRectangularNode (top, left, height or width) the property's,
change only the selection rectangle in the editor. The rectangle remains unchanged.


With other Objects (TRoundRectangularNode and TEllipticNode) it works smoothly.
Any idea?

I use Delphi 2009 and Vista.

Thank you for the great Components!

I couldn't regenerate the problem on Delphi 2009 and Vista.

By the way, regarding other problem mentioning in your email...

The OnCloseQuery event handler of the form needs to be revised to the following code:

Code: Select all

procedure TMainForm.FormCloseQuery(Sender: TObject;var CanClose: Boolean);
begin
  if IsGraphSaved then
  begin
    SimpleGraph.Clear;
    CanClose := True;
  end
  else                           // was missing
    CanClose := False;           // was missing
end;

The changes i make in the Node Property Dialog are in the attachment.

Not only TRectangularNode, but also all other nodes suffering from that problem.

On line #6142 of SimpleGraph.pas, replace

Code: Select all

      if not IsUpdateLocked then
        BoundsChanged(dX, dY, dCX, dCY)
      else
        Changed([gcView, gcData, gcText, gcPlacement]);


with

Code: Select all

      BoundsChanged(dX, dY, dCX, dCY);

Thank you for reporting the bug.

It is better to use SetBounds method instead of setting Left, Top, Width, and Height properties individually.

Thank you, it works fine.
