Field Detail

zero

private java.awt.Dimension zero

Constructor Detail

VoidComponent

public VoidComponent()

Method Detail

getHeight

public int getHeight()

Description copied from class: javax.swing.JComponent

Returns the height of this component. Prefer this method over JComponent.getBounds(java.awt.Rectangle)>JComponent.getBounds(java.awt.Rectangle) 55 or JComponent.getSize(java.awt.Dimension)>JComponent.getSize(java.awt.Dimension) 55 because it does not cause any heap allocation.

---

getMaximumSize

public java.awt.Dimension getMaximumSize()

Description copied from class: javax.swing.JComponent

Get the component's maximum size. If the JComponent.maximumSize>JComponent.maximumSize 55 property has been explicitly set, it is returned. If the JComponent.maximumSize>JComponent.maximumSize 55 property has not been set but the JComponent.ui>JComponent.ui 55 property has been, the result of ComponentUI.getMaximumSize(javax.swing.JComponent)>ComponentUI.getMaximumSize(javax.swing.JComponent) 55 is returned. If neither property has been set, the result of Container.getMaximumSize()>Container.getMaximumSize() 55 is returned.

---

getMinimumSize

public java.awt.Dimension getMinimumSize()

Description copied from class: javax.swing.JComponent

Get the component's minimum size. If the JComponent.minimumSize>JComponent.minimumSize 55 property has been explicitly set, it is returned. If the JComponent.minimumSize>JComponent.minimumSize 55 property has not been set but the JComponent.ui>JComponent.ui 55 property has been, the result of ComponentUI.getMinimumSize(javax.swing.JComponent)>ComponentUI.getMinimumSize(javax.swing.JComponent) 55 is returned. If neither property has been set, the result of Container.getMinimumSize()>Container.getMinimumSize() 55 is returned.

---

getPreferredSize

public java.awt.Dimension getPreferredSize()

Description copied from class: javax.swing.JComponent

Get the component's preferred size. If the JComponent.preferredSize>JComponent.preferredSize 55 property has been explicitly set, it is returned. If the JComponent.preferredSize>JComponent.preferredSize 55 property has not been set but the JComponent.ui>JComponent.ui 55 property has been, the result of ComponentUI.getPreferredSize(javax.swing.JComponent)>ComponentUI.getPreferredSize(javax.swing.JComponent) 55 is returned. If neither property has been set, the result of Container.getPreferredSize()>Container.getPreferredSize() 55 is returned.

---

getSize

public java.awt.Dimension getSize()

Description copied from class: java.awt.Component

Returns the size of this object.

---

getWidth

public int getWidth()

Description copied from class: javax.swing.JComponent

Returns the width of this component. Prefer this method over JComponent.getBounds(java.awt.Rectangle)>JComponent.getBounds(java.awt.Rectangle) 55 or JComponent.getSize(java.awt.Dimension)>JComponent.getSize(java.awt.Dimension) 55 because it does not cause any heap allocation.

---

paint

public void paint(java.awt.Graphics g)

Description copied from class: javax.swing.JComponent

Paint the component. This is a delicate process, and should only be called from the repaint thread, under control of the javax.swing.RepaintManager. Client code should usually call Component.repaint()>Component.repaint() 55 to trigger painting.

The body of the paint call involves calling JComponent.paintComponent(java.awt.Graphics)>JComponent.paintComponent(java.awt.Graphics) 55 , JComponent.paintBorder(java.awt.Graphics)>JComponent.paintBorder(java.awt.Graphics) 55 , and JComponent.paintChildren(java.awt.Graphics)>JComponent.paintChildren(java.awt.Graphics) 55 in order. If you want to customize painting behavior, you should override one of these methods rather than paint.

For more details on the painting sequence, see this article.

---

setSize

public void setSize(java.awt.Dimension d)

Description copied from class: java.awt.Component

Sets the size of this component to the specified value.

---

setSize

public void setSize(int w,
                    int h)

Description copied from class: java.awt.Component

Sets the size of this component to the specified width and height.

---

update

public void update(java.awt.Graphics g)

Description copied from class: javax.swing.JComponent

Call JComponent.paint(java.awt.Graphics)>JComponent.paint(java.awt.Graphics) 55 .
