I have successfully added third-party layout classes as well as my own Matisse forms to the Matisse palette custom folder, and they work as expected in Matisse. However, in a couple of cases I have created a Matisse form, added it to the palette and, though it shows up in the Custom folder I am unable to select it to be added to my layout, either by drag-and-drop or by the “Add From Palette” right-click command.
I have read the overview and tutorial documentation and examples on customizing the palette, but have found no checklist or description of the characteristics of a form or widget to function reliably from the palette. My forms that work and my forms that don’t work from the palette may extend the same class (e.g. JPanel).
I would appreciate if anyone could clarify this for me.
Thanks,
Tom
