enable	Sensitise widget	Shell variable name
disable	Desensitise widget	Shell variable name
refresh	Reload input data	Shell variable name
save	Save widget data	Shell variable name

The following general functions can be performed by any widget capable of emitting signals:

Type	Description	Parameter	Since
command	Execute command	Shell command
exit	Exit dialog	A value for the `EXIT` shell variable
closewindow	Close launched dialog	Launched dialog's shell variable name
launch	Launch new dialog	New dialog's shell variable name

Notes

1. Setting the "use-alpha" tag attribute to true will enable alpha selection. Alpha can be passed in following the #rrggbb value separated by a '|' character, or via the "alpha" tag attribute. Although the colour selection dialog displays alpha as an 8bit 0-255 value, GTK+ and Gtkdialog manage it as a 16bit 0-65535 value and therefore it'll require converting between the two formats. To convert from 8bit to 16bit use alpha * 257 and from 16bit to 8bit use (alpha + 257 / 2) / 257.

This widget was introduced in version 0.7.21.
