构造器详细资料

ImagePreviewPane

public ImagePreviewPane()

方法详细资料

getImage

public java.awt.Image getImage()

Return image

getImageWithSuffix

public ImageWithSuffix getImageWithSuffix()

Return ImageWithSuffix

setImageWithSuffix

public void setImageWithSuffix(ImageWithSuffix image)

Set image.

指定者:

setImageWithSuffix 在接口中 ImagePreviewer

参数:

image - the new image.

showLoading

public void showLoading()

从接口复制的说明: ImagePreviewer

显示正在加载

指定者:

showLoading 在接口中 ImagePreviewer

getPreferredSize

public java.awt.Dimension getPreferredSize()

Paint component.

覆盖:

getPreferredSize 在类中 javax.swing.JComponent

addChangeListener

public void addChangeListener(javax.swing.event.ChangeListener changeListener)

Add change listener.

getPreferredScrollableViewportSize

public java.awt.Dimension getPreferredScrollableViewportSize()

Returns the preferred size of the viewport for a view component. This is implemented to do the default behavior of returning the preferred size of the component.

指定者:

getPreferredScrollableViewportSize 在接口中 javax.swing.Scrollable

返回:

the preferredSize of a JViewport whose view is this Scrollable

getScrollableUnitIncrement

public int getScrollableUnitIncrement(java.awt.Rectangle visibleRect,
                             int orientation,
                             int direction)

Components that display logical rows or columns should compute the scroll increment that will completely expose one new row or column, depending on the value of orientation. Ideally, components should handle a partially exposed row or column by returning the distance required to completely expose the item.

The default implementation of this is to simply return 10% of the visible area. Subclasses are likely to be able to provide a much more reasonable value.

指定者:

getScrollableUnitIncrement 在接口中 javax.swing.Scrollable

参数:

visibleRect - the view area visible within the viewport

orientation - either SwingConstants.VERTICAL or SwingConstants.HORIZONTAL

direction - less than zero to scroll up/left, greater than zero for down/right

返回:

the "unit" increment for scrolling in the specified direction

抛出:

java.lang.IllegalArgumentException - for an invalid orientation

另请参阅:

JScrollBar.setUnitIncrement(int)

getScrollableBlockIncrement

public int getScrollableBlockIncrement(java.awt.Rectangle visibleRect,
                              int orientation,
                              int direction)

Components that display logical rows or columns should compute the scroll increment that will completely expose one block of rows or columns, depending on the value of orientation.

The default implementation of this is to simply return the visible area. Subclasses will likely be able to provide a much more reasonable value.

指定者:

getScrollableBlockIncrement 在接口中 javax.swing.Scrollable

参数:

visibleRect - the view area visible within the viewport

orientation - either SwingConstants.VERTICAL or SwingConstants.HORIZONTAL

direction - less than zero to scroll up/left, greater than zero for down/right

返回:

the "block" increment for scrolling in the specified direction

抛出:

java.lang.IllegalArgumentException - for an invalid orientation

另请参阅:

JScrollBar.setBlockIncrement(int)

getScrollableTracksViewportWidth

public boolean getScrollableTracksViewportWidth()

Returns true if a viewport should always force the width of this Scrollable to match the width of the viewport. For example a normal text view that supported line wrapping would return true here, since it would be undesirable for wrapped lines to disappear beyond the right edge of the viewport. Note that returning true for a Scrollable whose ancestor is a JScrollPane effectively disables horizontal scrolling.

Scrolling containers, like JViewport, will use this method each time they are validated.

指定者:

getScrollableTracksViewportWidth 在接口中 javax.swing.Scrollable

返回:

true if a viewport should force the Scrollables width to match its own

getScrollableTracksViewportHeight

public boolean getScrollableTracksViewportHeight()

Returns true if a viewport should always force the height of this Scrollable to match the height of the viewport. For example a columnar text view that flowed text in left to right columns could effectively disable vertical scrolling by returning true here.

Scrolling containers, like JViewport, will use this method each time they are validated.

指定者:

getScrollableTracksViewportHeight 在接口中 javax.swing.Scrollable

返回:

true if a viewport should force the Scrollables height to match its own

setImageStyle

public void setImageStyle(Style imageStyle)

从接口复制的说明: ImagePreviewer

设置图片样式(平铺,拉伸)

指定者:

setImageStyle 在接口中 ImagePreviewer

参数:

imageStyle - 样式

setImage

public void setImage(java.awt.Image image)

从接口复制的说明: ImagePreviewer

设置图片

指定者:

setImage 在接口中 ImagePreviewer

参数:

image - 图片

getImageStyle

public Style getImageStyle()
