GUI Builder Visual Feedback Legend
This document describes visual feedback the IDE's GUI Builder (formerly code-named Matisse)
provides during the process of Java GUI creation.
Alignment guidelines appear only when adding or moving components,
indicating the preferred positions to which components snap when the mouse button is released.
Once positioned, alignment guidelines are replaced by solid lines illustrating
the common alignments shared among components as well as anchoring indicators.
Once components have snapped into position, solid anchoring indicators
appear illustrating the common alignments shared among components.
||Anchors connecting individual components to the
containers within which they are located are represented by small
semi-circular indicators with dashed lines extending from the
container edge to the component itself.
||Anchors connecting individual components to
adjacent components are represented by small semi-circular indicators
with dashed lines extending from the one component to the other.
|Same Sizing is the state in which a group of components
(adjacent or otherwise) are all set to have the same width or height.
Same Sizing is illustrated by the appearance of small rectangular
indicators appearing on the top edge of each component for which
the property is set.
Auto-Resizing is the state in which a component's
width or height is set to resize dynamically at runtime.
Auto-Resizing is indicated by the state of the horizontal and vertical
Resizing buttons (called Change horizontal resizeability and Change vertical resizeability respectively) in the GUI Builder's toolbar. Auto-Resizing is enabled by selecting resizable in the Other Properties list in the Properties window.
Highlighting and Handles
||Orange highlighting indicates where a selected component is going to be placed.
|| Small square resize handles appear around a component's perimeter when a component is selected. Clicking, holding, and dragging a handle on the edge of a component resizes the latter.
