Re: Grid with Dots

Hi Chris,

It really depends on what exactly should be the behaviour of
"grid-with-dots" functionality.

1) If you want to have widgets to align to a grid during their movement
then:
a) use a MoveAction created with your own MoveStrategy where you
calculate with your grid-size. For example see:
graph/lib/src/org/netbeans/modules/visual/action/SnapToGridMoveStrategy.java

2) If you want Widgets to be instantly aligned to a grid, then you
should implement an Layout interface and assign it to the scene or layer
widget. This makes the children Widgets to be alligned instantly.

3) If you want to allow users to move Widgets on a scene freely within a
grid then:
a) implement the 1. case,
b) when you add a new Widget to a scene, check/calculate correct
preferred location of the new Widget based on the grid-size,
c) when an user changes the grid height or width, then
change/recalculate new correct preferred locations of all Widgets.

Regards,
  David
