Hi,

there are multiple ways:

With version 1.21 this can be done automatically by adding flowchildren="v" (and optionally also a childmargin) to the parent layer. Then the parent layer will take the size of its children:

Code

<layer type="container" ... flowchildren="v" childmargin="5">
   <layer type="text" ... />
</layer>

Or use the onresize event (also version 1.21) on the inner layer and transfer the size back to the parent (plus optionally some adjustments):

Code

<layer ... onresize="parentobject.width = width + 10;" />

Best regards,
Klaus

Hello Klaus. can i also read out the lowest layer in a hierarchy and bring this value to the parent.
for example the value from text2 (see code below)

Code

<layer type="container" ... flowchildren="v" childmargin="5">
   <layer type="img" ... >
   <layer type="vector" ... >
   <layer type="text1" ... >
   <layer type="text2" ... />
</layer></layer></layer>

You could loop through parentobject until it is null, but when you know the hierarchy, it might easier just to use e.g.
parentobject.parentobject.parentobject.width = ...;
to go a certain steps upward...
