getComponentback to summary
public JComponent getComponent()

Implements sun.swing.LightweightContent.getComponent.

Doc from sun.swing.LightweightContent.getComponent.

The client application overrides this method to return the JComponent instance which the JLightweightFrame container will paint as its lightweight content. A hierarchy of components contained in this component should not contain any heavyweight objects.

imageBufferResetback to summary
public void imageBufferReset(int[] data, int x, int y, int width, int height, int linestride)

Overrides default sun.swing.LightweightContent.imageBufferReset.

Doc from sun.swing.LightweightContent.imageBufferReset.

The default implementation for #imageBufferReset uses a hard-coded value of 1 for the scale factor. Both the old and the new methods provide default implementations in order to allow a client application to run with any JDK version without breaking backward compatibility.

imageBufferResetback to summary
public void imageBufferReset(int[] data, int x, int y, int width, int height, int linestride, double scaleX, double scaleY)

Overrides default sun.swing.LightweightContent.imageBufferReset.

Doc from sun.swing.LightweightContent.imageBufferReset.

JLightweightFrame calls this method to notify the client application that a new data buffer has been set as a content pixel buffer. Typically this occurs when a buffer of a larger size is created in response to a content resize event.

The method reports a reference to the pixel data buffer, the content image bounds within the buffer and the line stride of the buffer. These values have the following correlation. The width and height matches the layout size of the content (the component returned from the getComponent method). The x and y is the origin of the content, (0, 0) in the layout coordinate space of the content, appearing at data[y * scaleY * linestride + x * scaleX] in the buffer. A pixel with indices (i, j), where (0 <= i < width) and (0 <= j < height), in the layout coordinate space of the content is represented by a scaleX * scaleY square of pixels in the physical coordinate space of the buffer. The top-left corner of the square has the following physical coordinate in the buffer: data[(y + j) * scaleY * linestride + (x + i) * scaleX].

imageReshapedback to summary
public void imageReshaped(int x, int y, int width, int height)

Implements sun.swing.LightweightContent.imageReshaped.

Doc from sun.swing.LightweightContent.imageReshaped.

JLightweightFrame calls this method to notify the client application that the content image bounds have been changed within the image's pixel buffer.

imageUpdatedback to summary
public void imageUpdated(int dirtyX, int dirtyY, int dirtyWidth, int dirtyHeight)

Implements sun.swing.LightweightContent.imageUpdated.

Doc from sun.swing.LightweightContent.imageUpdated.

JLightweightFrame calls this method to notify the client application that a part of the content image, or the whole image has been updated. The method reports bounds of the rectangular dirty region. The dirtyX and dirtyY is the origin of the dirty rectangle, which is relative to the origin of the content, appearing at data[(y + dirtyY] * linestride + (x + dirtyX)] in the pixel buffer (see imageBufferReset). All indices data[(y + dirtyY + j) * linestride + (x + dirtyX + i)] where (0 <= i < dirtyWidth) and (0 <= j < dirtyHeight) will represent valid pixel data, (i, j) in the coordinate space of the dirty rectangle.

maximumSizeChangedback to summary
public void maximumSizeChanged(int width, int height)

Implements sun.swing.LightweightContent.maximumSizeChanged.

Doc from sun.swing.LightweightContent.maximumSizeChanged.

JLightweightFrame calls this method to notify the client application that the content maximum size has changed.

minimumSizeChangedback to summary
public void minimumSizeChanged(int width, int height)

Implements sun.swing.LightweightContent.minimumSizeChanged.

Doc from sun.swing.LightweightContent.minimumSizeChanged.

JLightweightFrame calls this method to notify the client application that the content minimum size has changed.

paintLockback to summary
public void paintLock()

Implements sun.swing.LightweightContent.paintLock.

Doc from sun.swing.LightweightContent.paintLock.

JLightweightFrame calls this method to notify the client application that it acquires the paint lock. The client application should implement the locking mechanism in order to synchronize access to the content image data, shared between JLightweightFrame and the client application.

paintUnlockback to summary
public void paintUnlock()

Implements sun.swing.LightweightContent.paintUnlock.

Doc from sun.swing.LightweightContent.paintUnlock.

JLightweightFrame calls this method to notify the client application that it releases the paint lock. The client application should implement the locking mechanism in order to synchronize access to the content image data, shared between JLightweightFrame and the client application.

public void preferredSizeChanged(int width, int height)

Implements sun.swing.LightweightContent.preferredSizeChanged.
