New Post: 1 point draw 4 lines

olezen — Thu, 21 Feb 2013 09:58:20 GMT

Hello
I fell over Live Geometry project in a Microsoft group.
And I must say that I am impressed :-)

Now I have started to play around with the package, and would like to draw a shape consisting of several lines and a height and width with a mouse click and then specify the height and width.

I just can not quite figure out how I make the last 3 points...

 protected override IEnumerable<IFigure> CreateFigures()
        {
            var p1 = FoundDependencies[0] as IPoint;
            
            var p2 = new Point(p1.Coordinates.X + 10, p1.Coordinates.Y);
            var p3 = new Point(p1.Coordinates.X + 10, p1.Coordinates.Y + 10);
            var p4 = new Point(p1.Coordinates.X, p1.Coordinates.Y + 10);
            
            
            var side0 = Factory.CreateSegment(Drawing, p1, p2);
            var side1 = Factory.CreateSegment(Drawing, p2, p3);
            var side2 = Factory.CreateSegment(Drawing, p3, p4);
            var side3 = Factory.CreateSegment(Drawing, p4, p1);
            var midpoint0 = Factory.CreateMidPoint(Drawing, side0);
            var midpoint1 = Factory.CreateMidPoint(Drawing, side1);
            var midpoint2 = Factory.CreateMidPoint(Drawing, side2);
            var midpoint3 = Factory.CreateMidPoint(Drawing, side3);

            var added = new IFigure[]
            {
                side0, 
                side1,
                side2,
                side3,
            };


            foreach (var item in added)
            {
                yield return item;
            }
        }

So I would like even control the coordinates of points B, C and D

Can you help me started?

Thank you in advance

New Post: Direction Needed...Where to look

ramjet69 — Fri, 25 Jan 2013 17:35:27 GMT

Hello,

I was directed to this project from a MSDN forum post and I am definitely going to download the source and see if I can provide any useful contributions. I however need a quick pointer as to where to begin with my specific addition. Here is my business need and my thought is to just extend this product, satisfy my business need and submit the extension for review.

My objective is to randomly create polygons for student analysis. The number of sides could be up to twenty and each length is random so...The number of sides would be randomly generated from 4-20 and then the length of each side would be randomly generated. Now to make things a bit more complicated I need the shape on some sort of a grid so students can calculate perimeter, area etc.

So as I opened with I'm not asking anyone to do my job for me just point my nose in the right direction.

Thank You

New Post: Segment and Ray

KirillOsenkov — Fri, 22 Jun 2012 07:10:01 GMT

Generally, all you need to define your own figure is the actual figure class, and a corresponding Creator class (that defines which dependencies are required to be entered by the user to fully specify your figure).

Segment, Ray and Line all inherit from LineBase.

LineBase defines a property called OnScreenCoordinates, which returns a PointPair of actual endpoints drawn in the viewport.

The default LineBase implementation is just to return Coordinates (the two dependency points joined together).

However Ray overrides this virtual property with an implementation which uses the first dependency point as is, and extends the second point of OnScreenCoordinates till the edge of the viewport.

Line overrides this virtual property to extend both ends of the line to the edges of the viewport.

The math to extend a line to end at the viewport edge is in Math.GetLineFromSegment().

Hope this helps,

Kirill

New Post: Segment and Ray

bbuten — Mon, 04 Jun 2012 00:37:49 GMT

Hi,

I've been looking at the source code for a while now. I'm interested in creating new types of figures. I'm looking at how the figures are created to get a better understanding what to do to create a new figure, but I must be missing something.

Take, for example, the ray and the segment. I think I understand the part about dependencies, and both these figures have the same point, point dependency. But where is it defined that the segment line ends at the second point and where the ray line continues on? I would think the segment and ray classes would have that kind of logic, but it doesn't look like it.

Can someone point me in the right direction? thanks.

New Post: Vector Styles

padraigoleary — Tue, 24 Apr 2012 08:52:43 GMT

Hey,

Firstly, great work on LiveGeometry. It is a fantastic geometry engine.

I have a question relating to Vector styles. It appears the Vector style is taken from the current Segment style. I can't overwrite the style and I cannot see where the association between Segment style and Vector style is made.

Has anyone changed the vector styles?!

New Post: Brilliant But Impractical Program

tvmogul — Mon, 27 Feb 2012 12:37:06 GMT

This program is a brilliant work and teh author is a genius BUT it is totally impractical as it currently stands.

I am a television producer and my hobby is programming. When I create a show for TV it must accomplish a goal of selling either a product or advertising or both that makes money which is practical. You created an incedible program and didn't even include a single practical thing in it ? Why not?

As an example, let's put a practical tool in this application, say a Joist Calculator. Floor Joists come in certain fixed widths and are spaced by some fixed distance. Say our Joists are 4 inches wide and spaced one foot apart and that they run vertical. A practical Tool that you could have included was a Joist calculator that would fill an area with a group of rectangles representing the Joists covering a floor and the user would then select a Joist tool that would allow the user to click between the Joists and a LINE would then be placed from one horizontal side to the parallel side of the floor plan. The the Joist Calculator would sum up the linear lengths of these lines and that would give you the total LINEAR length of say heating elements require. This is a practical example that would put your "Live Geometry" on the map. But I noticed that you didn't even include a rectangle in your elements? Is this project dead?

This is a brilliant piece of work and if you add some practical tools the application will be become famous--really famous.

It has enough "geometry" in it now--it needs practical things added to make it really robust.

You need to add a RECTANGLE where each side is parallel to an axis. This is the most useful shape in any CAD application and I am amzed you haven't added it? Why?

New Post: How Do I Add This Rectangle As A Behavior?

tvmogul — Sat, 25 Feb 2012 15:03:04 GMT

Hi,

The Rectangle. in my opinion, is the MOST important shape there is in the real world. If I were to try and draw a layout of a floor plan for a house using this tool it would be very hard without a Rectangle!

Below is a xml drawing of a Rectangle that allows you to change the length of either side--it is the rectangle that YOU created but never included?

I want to add this as a default behavior just like you have a square as one of your default behaviors.

I found one way to do this but it creates a new drawing--I want to add this as a behavior or at least be able to add this Rectangle to an EXISTING drwaing.

How can I make this Rectangle a default behavior? Thank you.

One more question--can I add this xml as a resource to the application and load this resource to an existing drawing? If so, how?

Here is the Rectangle:

New Post: Problem Coloring PropertGrid

tvmogul — Fri, 24 Feb 2012 21:16:54 GMT

Hi, Thank you for responding....

I posted an image of the problem on my website:

http://www.domain-genie.com/images/bug.png

If you look at this picture of the PropertyGrid you will see that I was able to change PART of the BackColor to Gra.

The border is colored Black BUT there is a rectangle of YELLOW around the PropertyGrid--what is this rectangle?

Below is the exact code for DrawingHost from your latest version posted on this website:

For example: The change I make to CreatePropertyGrid() below such as making the colors all black do NOT appear anywhere in the PropertyGrid ????? Is the code haunted?

protected void CreatePropertyGrid() { propertyGridScrollViewer = new ScrollViewer() { HorizontalScrollBarVisibility = ScrollBarVisibility.Auto, VerticalScrollBarVisibility = ScrollBarVisibility.Auto, Margin = new Thickness(8), HorizontalAlignment = HorizontalAlignment.Right, VerticalAlignment = VerticalAlignment.Top, MinWidth = 200.0, //Background = new SolidColorBrush(Color.FromArgb(255, 213, 220, 232)), Background = new SolidColorBrush(Color.FromArgb(255, 0, 0, 0)), BorderBrush = new SolidColorBrush(Colors.Black), Visibility = Visibility.Collapsed };
PropertyGrid = new PropertyGrid(); MEFHost.Instance.SatisfyImportsOnce(PropertyGrid); PropertyGrid.Margin = new Thickness(4); propertyGridScrollViewer.Content = PropertyGrid; PropertyGrid.VisibilityChanged += PropertyGrid_VisibilityChanged;
Canvas.SetZIndex(propertyGridScrollViewer, (int)ZOrder.StatusBar);
PropertyGrid.ValueDiscoveryStrategy = new ExcludeByDefaultValueDiscoveryStrategy();
//WS NO CHANGE IN COLOR of PropertyGrid ??????
//propertyGridScrollViewer.Background = new SolidColorBrush(Color.FromArgb(200, 213, 220, 232)); //PropertyGrid.Background = new SolidColorBrush(Color.FromArgb(200, 213, 220, 232)); //propertyGridScrollViewer.Background = new SolidColorBrush(Color.FromArgb(200, 213, 220, 232)); propertyGridScrollViewer.Background = new SolidColorBrush(Color.FromArgb(255, 0, 0, 0)); PropertyGrid.Background = new SolidColorBrush(Color.FromArgb(255, 0, 0, 0)); propertyGridScrollViewer.Background = new SolidColorBrush(Color.FromArgb(255, 0, 0, 0));

New Post: How would you remove the negative axes?

tvmogul — Fri, 24 Feb 2012 21:07:19 GMT

Hi,

As I have said, your work is brilliant!

I am a television producer and my hobby is programming. In my work on television I spend a lot of time and attention on the GUI--the "Look & Feel" of a TV show or software application is what draws people...

Many people, like myself prefer working on a Grid that has NO negative axes and the origin is in the lower right-hand corner of the screen.

How would you eliminate the negative axes and position the Origin in the lower left-hand corner of the screen just showing the positive x-axis and poitive y-axis?

Thanks!

Not sure why this is not working for you. You are making changes in DrawingHost.CreatePropertyGrid() right? I believe the border is black not yellow. You would change it to gray by changing the BorderBrush. For the status message make similar changes to DrawingHost.CreateStatusBar().

Hi,

From inside say Page.cs... How would you programatically click one of the ToolButtons?

I tried several ways but in evertry case I keep getting a null exception.

So if I want to Click a toolButton programatically from inside of Page.cs how do you do it?

The method calls made and properties set by clicking a button would be easier to work with if they were reachable from Page.cs.

Can you give us one example of how to click a toolbutton programatically? Thanks!

Hi, First, you are a genius! Incredible piece of work... Congratulations!

I was trying to change the default color of the PropertyGrid.
It seemns that the PropertyGrid in your latest SilverlightClient code has a background and a border that are both Yellow.

I was able to change the default color of the background of the PropertyGrid from Yellow to Gray BUT the border of the PropertyGrid still remains Yellow no matter what changes I make--I changed all the "yellow" colors to "gray" but the border of the PropertyGrid is still Yellow!

Could you please tell me how to change both the background AND the BORDER of the PropertyGrid to Gary so that the entire PropertyGrid is Gray?

How to change the background color of the Status message to gray?

Thank you!

How do I resolve this problem?

Others such as the following, all I want to hide, because these methods have abnormal behavior.

To create .xap files you need Visual Studio 2010 Professional or higher and a knowledge of C#. You can find more details at http://www.silverlight.net/.

Why don't you want to use the .xap file that I've already compiled? It's at http://livegeometry.com/LiveGeometry.xap.
