|

|

This widget provides a button showing either a linked or a broken
|
||||
chain that can be used to link two entries, spinbuttons, colors
|
||||
or other GUI elements and show that they may be locked. Use it for
|
||||
example to connect X and Y ratios to provide the possibility of a
|
||||
constrained aspect ratio.

</para>

<para>
|
||||
The #GimpChainButton only gives visual feedback, it does not really
|
||||
connect widgets. You have to take care of locking the values yourself
|
||||
by checking the state of the #GimpChainButton whenever a value changes
|
||||
in one of the connected widgets and adjusting the other value if
|
||||
necessary.
