OT Routing routine

[Marc Vanzegbroeck]

Hi,

I have a program in FW then convert text-files to a graphical output.
It is working fine (more the 10 years already ), but I want to extend it so the drawing can be larger.

I read the text-file into a database , and then I have a table with connection.
L1 - not-BLOCK5
L2 - BLOCK5
BLOCK5 - BLOCK6
...
..
the result is


In my routine I calculate the position of the blocks, and the coordinates of the lines.

Sometimes, in a more complex drawing, the drawing is not that clear, like this one:


If I want bigger drawings, it will be more difficult en not that clear

A search the internet to some routing programs. yWorks seems nice, but not cheap...

Other ones did't have nice output's.
Doos anyone know a alternative?

I was thinking to create a new routine, that can handle more complex drawings. Does anyone have a suggestion for a routine?

Thanks,

[Antonio Linares]

Marc,

Very nice app, congratulations

Could you post here some screenshots of yWorks ? thanks

Antonio,

This is not done with yWorks, but with a routine I wrote myself .
It is done with LineTo() MoveTo(), ellipse(),.... functions
Because I want some more complex(bigger) drawings, I was considering using yWorks.

Here are some examples on the yWorks-site.

I already have try graphviz. The only problem is that the lines are not straight.
The is an option, but then the connections the the blocks are not on the correct place. That is still a bug that they know.

This is an example with graphviz; you helped me before for showing me svg-files

Marc,

Really amazing

Very interesting the yWorks examples !

Could you post an image of a complex drawing ? Just to get an idea of how bigger it may be

Antonio,

Here is an example where my routing is not nice

For yWorks an .NET-library exist. I don't know if we can link in to the FWH64-exe, or maybe create a seperate exe-file that FW calls for making the drawing...

Really fantastic

Marc,

> For yWorks an .NET-library exist. I don't know if we can link in to the FWH64-exe

We can not link native code (Harbour+FWH) with .NET code

But using FiveNet design you could manage the .NET library from your app:

https://bitbucket.org/fivetech/fivenet/wiki/Home

> , or maybe create a seperate exe-file that FW calls for making the drawing...

Thats basically what FiveNet does, but instead of using an external EXE, it uses a DLL.

Could you post a screenshot of how your screenshot may look like using yWorks ? thanks

Antonio,

If you want to see how it looks using yWorks, than I have to draw it with the free editor yEd of yWorks, and then do the autorouting.
I already modified an example that was used in de yWorks evaluation version of yWorks, but I can't use it anymore, because Visual Studio Cummunity 15 doesn't work anymore
I have a message that the 30 days of evaluation is over. I thought the Visual Studio Cummunity 15 was free...

I will create it in yEd and post the diagram

Its the only way to truly understand what you mean

It is free. You just have to register it.

It is free. You just have to register it.

Visual Studio is working again after registering

Antonio,

Is it correct that if the sample .cs code provided by yWorks is:

Code: Select all  Expand view

using System;
using System.Drawing;
using yWorks.Canvas;
using yWorks.Canvas.Drawing;
using yWorks.Canvas.Geometry.Structs;
using yWorks.yFiles.UI.Drawing;
using yWorks.yFiles.UI.Model;

namespace Demo.yFiles.Layout.PortCandidateDemo
{
  /// <summary>
  /// Basic implementation of port style. Renders a port as a circle.
  /// </summary>
  public class CirclePortStyle : SimpleAbstractPortStyle
  {
    private const double Width = 6;
    private const double Height = 6;
    private readonly Pen pen = new Pen(Brushes.Black);

    protected override void Paint(IPort port, Graphics graphics, IRenderContext renderContext) {
      var location = port.Location;
      graphics.DrawEllipse(pen, (float)(location.X - Width / 2), (float)(location.Y - Height/2), (float)Width, (float)Height);
    }

    protected override RectD GetBounds(IPort port, ICanvasContext canvasContext) {
      var location = port.Location;
      return new RectD(location.X-Width/2, location.Y-Height/2, Width, Height);
    }
  }[code][/code]

that I can call this directly from a FWH prg-file if I use the Fivenet library?

Marc,

If you create a .NET DLL the same way as FiveNet does, then you should be able to
instantiate an OLE object from the PRG once you register the .NET DLL as FiveNet does also.

In fivetech.cs there is a:

namespace FiveTech

and

public class FiveNet

then from the PRG we can do:

oFiveNet = win_oleCreateObject( "FiveTech.FiveNet" )

If you plan to use FiveNet and want to continue having tech support about it, please use the PayPal donate button from the FiveNet site, thanks
