SHape inside a shape

Print Post  
Hi Stoyan,

In my application, I have small shape inside a big shape.

So when I resize a outer Big shape, the inner shape size also increments/ decrements relative to outer shape.

I want it as follows:

1. I should be able to set minimum and maximum limiting size for inner shape.

2. Even if outer shape is resized upto any extent, inner shape should grow in size upto maximum limit.

Note: only outer shape has anchor points, not the inner shape

So how can I achieve such behaivor through mind fusion.

Thanks in advance,
Chetna

Hi Chetna,

Are you resizing the inner node in response to the outer node's NodeModifying event? The node.Constraints object contains properties such as MinWidth,MinHeight,MaxWidth,MaxHeight. They are applied only when a user modifies the node interactively, but you can still use them to store your min/max limits and check them when resizing from the event handler. E.g. assuming newRect contains the size you have calculated from the parent node:

Code
Select All
newRect = ... ; // calculated from outer node
var c = innerNode.Constraints;
newRect.Width = Math.Max(c.MinWidth, Math.Min(c.MaxWidth, newRect.Width));
newRect.Height = Math.Max(c.MinHeight, Math.Min(c.MaxHeight, newRect.Height));


I hope that helps,
Stoyan

Hello Stoyan,

Please refer the image attached.
Here the inner message shape should not grow beyond certain limit, even if I resize the outer rectangle of shape to any extent.

Note that anchor points are applied only to outer shape.

The code to create the node is also there in image.

Kind regards,
Chetna

Hi,

You cannot do this using a single Shape definition. You could use a second node attached to the main node to display the mail icon, and update its size with whatever constraints you need applied. Alternatively, change the ShapeNode template to show an additional Path object where the constraints are implemented via Silverlight's layout propeties such as Stretch, MinWidth, MinHeight.

I hope that helps,
Stoyan

Hi,

You can attach a node to another one using the AttachTo method:

mailNode.AttachTo(masterNode);

I hope that helps,
Stoyan
