- GimpChainButton
-
- <!-- ##### SECTION Short_Description ##### -->
- Widget to visually connect two entry widgets.
-
- <!-- ##### SECTION Long_Description ##### -->
- <para>
- 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.
