먼저 MigLayout이 JXLayer와 호환되지 않는 것으로 보입니다. 둘 다 사용하면 MigLayout을 사용하는 패널의 구성 요소에 예기치 않은 동작이 발생합니다.
그런 다음 원본 pbjar JXLayer를 사용하면 구성 요소를 레이어 창 가운데에만 놓을 수 있습니다. Pbjar 소스는 on github을 다운로드 할 수 있습니다. 이것은 공식 Piet Blok 저장소가 아닙니다.

I 발견 해결책은 TransformLayout, TransformUI를 수정하고, 상기 클래스 TranformModel :
Alignment ENUM은 층의 구성 요소에 대한 가능한 배열을 제공한다. TransformLayout에서
public enum Alignment {
TOP,
BOTTOM,
LEFT,
RIGHT,
CENTER
}
:
@Override
public void layoutContainer(Container parent) {
JXLayer<?> layer = (JXLayer<?>) parent;
LayerUI<?> layerUI = layer.getUI();
if (layerUI instanceof CustomTransformUI) {
JComponent view = (JComponent) layer.getView();
JComponent glassPane = layer.getGlassPane();
if (view != null) {
Rectangle innerArea = new Rectangle();
SwingUtilities.calculateInnerArea(layer, innerArea);
view.setSize(view.getPreferredSize());
Rectangle viewRect = new Rectangle(0, 0, view.getWidth(), view
.getHeight());
int x;
int y;
Alignment alignX = ((CustomTransformUI) layerUI).getAlignX();
Alignment alignY = ((CustomTransformUI) layerUI).getAlignY();
if(alignX == Alignment.LEFT) {
x = (int) (innerArea.getX() - viewRect.getX());
} else if(alignX == Alignment.RIGHT) {
x = (int) (innerArea.getX()+innerArea.getWidth()-viewRect.getWidth()-viewRect.getX());
} else {
x = (int) Math.round(innerArea.getCenterX()
- viewRect.getCenterX());
}
if(alignY == Alignment.TOP) {
y = (int) (innerArea.getY() - viewRect.getY());
} else if(alignY == Alignment.BOTTOM) {
y = (int) (innerArea.getY()+innerArea.getHeight()-viewRect.getHeight()-viewRect.getY());
} else {
y = (int) Math.round(innerArea.getCenterY()
- viewRect.getCenterY());
}
viewRect.translate(x, y);
view.setBounds(viewRect);
}
if (glassPane != null) {
glassPane.setLocation(0, 0);
glassPane.setSize(layer.getWidth(), layer.getHeight());
}
return;
}
super.layoutContainer(parent);
}
TransformUI에서 :
private Alignment alignX; // horizontal alignment
private Alignment alignY; // verticalalignment
public TransformUI(TransformModel model, Alignment alignX, Alignment alignY) {
super();
this.setModel(model);
this.alignX = alignX;
this.alignY = alignY;
}
public Alignment getAlignX() {
return alignX;
}
public Alignment getAlignY() {
return alignY;
}
TransformModel에서 :
private Alignment alignX = Alignment.CENTER;
private Alignment alignY = Alignment.CENTER;
public CustomTransformModel(Alignment alignX, Alignment alignY) {
super();
this.alignX = alignX;
this.alignY = alignY;
}
@Override
public AffineTransform getTransform(JXLayer<? extends JComponent> layer) {
JComponent view = (JComponent)layer.getView();
/*
* Set the current actual program values in addition to the user
* options.
*/
this.setValue(Type.LayerWidth, layer == null ? 0 : layer.getWidth());
this.setValue(Type.LayerHeight, layer == null ? 0 : layer.getHeight());
this.setValue(Type.ViewWidth, view == null ? 0 : view.getWidth());
this.setValue(Type.ViewHeight, view == null ? 0 : view.getHeight());
/*
* If any change to previous values, recompute the transform.
*/
if (!Arrays.equals(this.prevValues, this.values)) {
System.arraycopy(this.values, 0, this.prevValues, 0, this.values.length);
this.transform.setToIdentity();
if (view != null) {
double scaleX;
double scaleY;
double centerX;
if(this.alignX == Alignment.LEFT) {
centerX = 0.0;
} else if (this.alignX == Alignment.RIGHT){
centerX = layer == null ? 0.0 : (double)layer.getWidth();
} else {
centerX = layer == null ? 0.0 : (double)layer.getWidth()/2.0;
}
double centerY;
if(this.alignY == Alignment.TOP) {
centerY = 0.0;
} else if(this.alignY == Alignment.BOTTOM){
centerY = layer == null ? 0.0 : (double)layer.getHeight();
} else {
centerY = layer == null ? 0.0 : (double)layer.getHeight()/2.0;
}
AffineTransform nonScaledTransform = this.transformNoScale(centerX, centerY);
if (((Boolean)this.getValue(Type.ScaleToPreferredSize)).booleanValue()) {
scaleY = scaleX = ((Double)this.getValue(Type.PreferredScale)).doubleValue();
} else {
Area area = new Area(new Rectangle2D.Double(0.0, 0.0, view.getWidth(), view.getHeight()));
area.transform(nonScaledTransform);
Rectangle2D bounds = area.getBounds2D();
scaleX = layer == null ? 0.0 : (double)layer.getWidth()/bounds.getWidth();
scaleY = layer == null ? 0.0 : (double)layer.getHeight()/bounds.getHeight();
if (((Boolean)this.getValue(Type.PreserveAspectRatio)).booleanValue()) {
scaleY = scaleX = Math.min(scaleX, scaleY);
}
}
this.transform.translate(centerX, centerY);
this.transform.scale((Boolean)this.getValue(Type.Mirror) != false ? - scaleX : scaleX, scaleY);
this.transform.translate(- centerX, - centerY);
this.transform.concatenate(nonScaledTransform);
}
}
return this.transform;
}
는 이제 config로 줌 가능한 패널을 만들 수 있습니다 유휴 정렬 :
TransformModel model = new TransformModel(Alignment.LEFT, Alignment.TOP);
TransformUI ui = new TransformUI(model, Alignment.LEFT, Alignment.TOP);
new JXLayer((Component)component, (LayerUI)ui)
빠른 픽스입니다. 그것은 아마도 개선 될 수 있습니다.
