Constructor Details

Thumbnail

public Thumbnail()

Constructor to be called on the EDT.

Method Details

setImageIcon

public void setImageIcon(@NotNull
 @NotNull ImageIcon icon)

sets the image the Thumbnail. If we are not on the EDT this is submitted to the EDT.

Parameters:

icon - The ImageIcon that should be displayed

setVisible

public void setVisible(boolean visibility)

Overridden method to allow the setting of the size when not visible. This was a bit problematic as the Component which is showing the Thumbnails was not adjusting to the new image size. The revalidate() cured this.

Overrides:

setVisible in class JComponent

Parameters:

visibility - true for visible, false for non visible.

setFactor

public void setFactor(float thumbnailSizeFactor)

This method sets the scaling factor for the display of a thumbnail. 0..1

Parameters:

thumbnailSizeFactor - factor

setThumbnailSize

public void setThumbnailSize(int thumbnailSize)

Sets the maximum Thumbnail size

Parameters:

thumbnailSize - the maximum thumbnail size

getThumbnailSize

public int getThumbnailSize()

Returns the maximum thumbnail size

Returns:

the thumbnail size

getThumbnailDimension

public Dimension getThumbnailDimension()

Returns the maximum thumbnail dimension

Returns:

the thumbnail dimension

getPreferredSize

public Dimension getPreferredSize()

Returns the preferred size for the scaled Thumbnail as a Dimension using the thumbnailSize as width and height.

Overrides:

getPreferredSize in class JComponent

Returns:

Returns the preferred size for the scaled Thumbnail as a Dimension using the thumbnailSize as width and height.

getMaximumSize

public Dimension getMaximumSize()

Returns the maximum (scaled) size for the Thumbnail as a Dimension using the thumbnailSize as width and height.

Overrides:

getMaximumSize in class JComponent

Returns:

maximum size for the Thumbnail

setQueueIcon

public void setQueueIcon()

Sets an icon of a clock to indicate being on a queue

setLargeFolderIcon

public void setLargeFolderIcon()

Sets an icon showing a large yellow folder

drawOfflineIcon

public void drawOfflineIcon(boolean flag)

Indicates to the Thumbnail that it should or should not draw its Offline Status. Calls repaint()

Parameters:

flag - true if the little CD-rom icon should be drawn, false if not.

drawMailIcon

public void drawMailIcon(boolean flag)

indicates whether the mail icon should be drawn or not and calls repaint()

Parameters:

flag - true if it should be drawn, false if not

setSelected

public void setSelected()

Tells the thumbnail to render itself as a selected thumbnail

setUnSelected

public void setUnSelected()

Tells the thumbnail to stop rendering itself as a selected thumbnail

setTimestamp

public void setTimestamp(String timestamp)

Set the timestamp string to the supplied String. To suppress the timestamp set it to the empty String ""

Parameters:

timestamp - the new timestamp string.

paintComponent

public void paintComponent(Graphics graphics)

we are overriding the default paintComponent method, grabbing the Graphics handle and doing our own drawing here. Essentially this method draws a large white rectangle. A drawImage is then painted doing an affine transformation on the image to position it so the desired point is in the middle of the Graphics object.

Overrides:

paintComponent in class JComponent

Parameters:

graphics - Graphics
