Class LayoutStyle

java.lang.Object

vaadinx.swing.LayoutStyle

public class LayoutStyle
extends Object

Port of LayoutStyle (D_grouplayout). Required for the import-swap: NetBeans GUI-builder code references javax.swing.LayoutStyle.ComponentPlacement inside GroupLayout gap calls, which swaps to vaadinx.swing.LayoutStyle.ComponentPlacement — so this class must exist for such code to compile.

Only the LayoutStyle.ComponentPlacement enum is load-bearing. GroupLayout consumes it directly (mapping RELATED / UNRELATED to fixed pixel gaps in addPreferredGap), so it does not go through getPreferredGap(JComponent, JComponent, LayoutStyle.ComponentPlacement, int, Container)/getContainerGap(JComponent, int, Container) dispatch. The gap-computation methods are provided for API completeness and return R_layouts_close_enough defaults via EHelper.onUnimplemented(String, String, Object...) — no migrated code we target calls them (NetBeans emits the enum, not the LayoutStyle instance).

Kept concrete (JDK's is abstract) so getInstance() returns a usable object without a separate default subclass; non-final to preserve the JDK's extensible shape per R_swing_is_truth.

getPreferredGap

public int getPreferredGap(JComponent component1,
 JComponent component2,
 LayoutStyle.ComponentPlacement type,
 int position,
 Container parent)

Preferred gap between two components. Not on the migrated-code path (NetBeans hands LayoutStyle.ComponentPlacement to GroupLayout directly); returns GroupLayout's RELATED default (6px) as a sensible R_layouts_close_enough answer.

getContainerGap

public int getContainerGap(JComponent component,
 int position,
 Container parent)

Preferred gap between a component and the container edge. R_layouts_close_enough default (10px).
