Group Resizing & Text alignment dbts

Hi,

Plz let me know if the following 2 scenarios is possible in flowchart.net.

1) Can text in a box be aligned to top left corner?

2) I have a box A which has N boxes attached to it and these boxes are contained with the box A.  A is the mainobject in the group. When i resize A, I dont want its child items to go out of its bound. Also the resizing of child should not exceed the parent bound.   Is it possible to do this functionality ?

Regards
Vidhya Ganesan

Hi,

Set both the Alignment and LineAlignment properties of the Box.TextFormat to Near.

You can use the AttachTo(Node, percents...) method and the child nodes will be resized together with their parent staying within the parent bounds. We can add some new members to Node.Constraints to let you prevent moving/resizing a child outside of its parent.

Stoyan

Hi,

Thanks for your response.


Regd Group resizing, I will not be able to use AttachTo( percent) as i dont want to resize the child when the parent is resized.  I have written custom code to avoid the children going out of parent bounds when parent is resized. Plz let me know if there is any feature available to do this.

I am right now using Flowchart.net professional edition Version4.1.

You have mentioned that you can provide some new members in Node.Constraints to let us prevent moving/resizing a child outside of its parent.  Do we need to do a feature request to Mindfusion for this requirement?

Hi,

You might use custom drawing and set the clipping region to the group parent before calling the actual drawing code, e.g. try this

void fc_DrawBox(...)
{
  e.Graphics.Clip = new Region(parentRect);
  e.Box.CustomDraw = CustomDraw.None;
  e.Box.Draw(...);
  e.Box.CustomDraw = CustomDraw.Full;
  // clear the clipping region ...
}

You will get endless recursion in the DrawBox handler if you don't clear the CustomDraw attribute before calling Box.Draw.

Our developers will add a new property to NodeContraints in a few days.

This version adds a node.Constraints.KeepInParent property:

https://mindfusion.org/_temp/fccons.zip

Set it to true to prevent users from moving the node outside of its MasterGroup.MainObject node. The value of this property is not being serialized yet when saving files; it will be set to false when a diagram file is loaded.
