Increasing Table Group's size when placeholder size increases

My Group is a Table, which contains 3 columns of Panels: A table panel of ports, an auto panel for the body, and another table panel of ports.

The auto panel is as follows:

$(go.Panel, "Auto", {
    column: 1,
    stretch: go.GraphObject.Fill,
    contextMenu: nodeContextMenu
  },
  $(go.Shape, "RoundedRectangle", {
    //geometryStretch: go.GraphObject.Fill,
    fill: "white"
  }),
  $(go.Panel, "Horizontal", {},
    $(go.TextBlock, new go.Binding("text", "name"))
  ),
  $(go.Placeholder)
)

The behavior I see now is that the auto panel expands to be either larger than the Placeholder, OR the table panels of ports, but not both.

Without any modifier properties, the default behavior will be for the Auto panel to expand to be larger than the placeholder.

Putting a { stretch: go.GraphObject.Fill } on the panel, or a { geometryStretch: go.GraphObject.Fill } on the shape will cause the Auto panel/shape to expand to encompass the placeholder, but not expand to the height of the neighboring columns.

The behavior I want is for the Auto panel to expand to be larger than the size of the placeholder && size of the table panels of ports.

What can I do to get my desired behavior?

Hi,

Is there a way where I can tell the graph to always stay connected ?

for example ,i create the following graph with nodesize(140,140)

then i change the node size (140,50)

the link breaks .

I can get it to connect to the ports by not specifying points ,

what I want is to check if the links are connected properly to the nodes , if it is not connected , connect them automatically. I want to give high priority to the ports than the points (path that the link takes ) ? is this possible ?

Hi,

if i have a single node(there is no graph on the left or right side) and try to horizontal scroll , the node scrolls to the end of left side , i want the scrolling to take place only if there is graph that is not displayed in the view port , how can i achieve this

in the flowchart example http://gojs.net/latest/samples/flowchart.html , i had a single node and tried horizontal scroll , the node flies in the direction even thought there is nothing more to show

Links between a group and its members

As I recall (but cannot find in the change log), you improved routing of links between a group and its members to be "internal" without going outside of this group. I see this working if a group has just one member, but starting with a second member routing goes outside the group.

Getting mouse events over GoJS surface

@catface wrote:

hi,

since I upgraded to goJS 1.6.1 document level mouse events don't work if they happen over the GoJS surface... is this a new thing?... can it be turned off?... my guess is goJS marks those events as handled or something... :-S

I have 2 scenarios that suffer from this... one is a context menu that doesn't hide when you click on goJS surface... and one is dragging and dropping from a "toolbox" that just stops when entering the goJS surface...

both those scenarios used to work fine in 1.5.5... and that upgrade is the only big thing that we changed... as far as I know.

thanks,
cAndrei

Hello,
I'm evaluating gojs for use in creating workflows and as part of the workflow creation process my users are able to create groups.

What I'm wondering is if it is possible to take the groups that are created and add them to a palette so that the user can re-use these groups.

hi

I have a question about Handle.

I made a BoundingHandle on my Drawing Object.
It is located directly in front of the upper right handle (size : 10 X 10)
I would like to use it as a button.
I implement the overring method 'AddSelectionHandle' and made a Boundinghandle.
The source code is shown below.

How to recognize recognize this handle when hovering mouse.
and how to use mouseDown Event at this moment and get this Handle.

I would like to operation resize handle.

public class MyDrawing : GoDrawing
{
public override void AddSelectionHandles(GoSelection sel, GoObject selectedObj)
{
base.RemoveSelectionHandles(sel);
base.AddSelectionHandles(sel, selectedObj);

        GoShape selectedShape = selectedObj as GoShape;
        IGoHandle handle = sel.CreateBoundingHandle(this, selectedObj);
        GoShape shape = handle.GoObject as GoShape;

        if (shape != null)
        {
            shape.Bounds = new RectangleF(selectedObj.Position.X + selectedObj.Width - 20, selectedObj.Position.Y - 5 , 10, 10);
            shape.BrushColor = Color.Red;
            shape.PenColor = Color.Black;
            shape.PenWidth = 1;
        }
    }

}

please some advices or example code.

thanks.

I see that there is a drop reject for background selection and object selection. Is there one for external objects? I need this feature to undo markup of the diagram (highlighting of items for example). Note that I am not dragging and dropping GoObjects.

Hello ,
I would buy gojs but are now being tested.

My question is:
1. you can not count items dragged so that they disappear from the palette
or make them "no selectable"?

  1. objects and arrows are programmable for the adapter?

  2. how can implement a contextmenu?

thanks for the answer

Problems with GoLink

@Denis wrote:

Hello!
Before I ask you my questions, I would like to describe my project requirements briefly.
Our view can have several types of objects on it.
Those objects can be connected with each other with their conectors.
The connectors implemented as GoLink descendants (It is MyLink class in the attached example).

Every object must be aligned by a view grid with its center.
Every connector must be orthogonal, its every point must be aligned by a view grid.
I've prepared a simple example to illustrate my questions. To simplify the example I didn't include objects that must be connected with connectors, there are only links (connectors) which can be connected with each other by relinking.
To be connected, the links have ports at the ends. You can drag one of a connector end to
another connector end to connect them. (To show ports, define conditional compilation symbol SHOW_PORTS for the whole project or only just for MyLink.cs).

Example link: https://yadi.sk/d/1VYC1jk4rJsW7

  1. Why do the ends of MyLink have offsets? Look at the pic1.png. I expect the first and last
    connector point coords are aligned by grid, but they are not. There is offset of 0.5. Ports have no size. Because of the offset I have a bit curved lines that connect objects and it looks not very good.

    pic1.png1594x1080 73 KB

  2. How can I achieve every connector (not only its ends) point to be aligned by grid? I need it when a connector is moving or relinking.
    This issue illustrated by pic2.png

    pic2.png1594x1080 91.5 KB

  3. When I move any intermediate connector point, sometimes I have situation when a link segments are not orthogonal to each other (pic3.png). How can I retain orthogonality moving intermediate connector points?

P.S. I use GoDiagram 5.1.0.4. My company has OEM License. I can send you the license information if needed.

                ),
            makePort("R", go.Spot.Right)
        ));

Where makePort() just returns a small square with port properties set.
This is how my node looks

The textBlock and port shape are organized how I want, but why isn't the panel and panel expander button positioned vertically under it? Should I maybe just use a table?
