GimpChainButton implements AtkImplementorIface and GtkBuildable.
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.
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.
GtkWidget * gimp_chain_button_new (
Creates a new GimpChainButton widget.
This returns a button showing either a broken or a linked chain and small clamps attached to both sides that visually group the two widgets you want to connect. This widget looks best when attached to a table taking up two columns (or rows respectively) next to the widgets that it is supposed to connect. It may work for more than two widgets, but the look is optimized for two.
The position you are going to use for the button with respect to the widgets you want to chain.
void gimp_chain_button_set_active (
Pointer to a GimpChainButton.
