まず、MigLayoutはJXLayerと互換性がないようです。両方を使用している場合、MigLayoutを使用するパネルのコンポーネントは予測できない動作をします。
元のpbjar JXLayerでは、レイヤーペインの中央にコンポーネントを配置することしかできません。 Pbjarソースはon githubをダウンロードできます。これは公式のPiet Blokリポジトリではないことに注意してください。
Iが見出さ溶液はTransformLayoutを変更することで、TransformUI、及びTranformModelクラス：
Alignment列挙は、層中の成分のための可能な整列を与えます。
TransformLayoutで
public enum Alignment {
TOP,
BOTTOM,
LEFT,
RIGHT,
CENTER
}
：
TransformUIで
@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);
}
：
TransformModelで
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;
}
：
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;
}
あなたは今設定でズーム可能なパネルを作成することができます調整可能なアライメント：
TransformModel model = new TransformModel(Alignment.LEFT, Alignment.TOP);
TransformUI ui = new TransformUI(model, Alignment.LEFT, Alignment.TOP);
new JXLayer((Component)component, (LayerUI)ui)
これはクイックフィックスです。それはおそらく改善することができます。
