Method Detail

previewTab

public void previewTab(javax.swing.JTabbedPane tabPane,
                       int tabIndex,
                       java.awt.Graphics g,
                       int x,
                       int y,
                       int w,
                       int h)

Draws a tab preview on the specified graphics.

Parameters:

tabPane - Tabbed pane.

tabIndex - tabIndex Tab index for the preview paint.

g - Graphics context.

x - X coordinate of the preview area.

y - Y coordinate of the preview area.

w - Width of the preview area.

h - Height of the preview area.

hasPreview

public boolean hasPreview(javax.swing.JTabbedPane tabPane,
                          int tabIndex)

Checks whether the specified tab component is previewable.

Parameters:

tabPane - Tabbed pane.

tabIndex - Tab index for the preview paint.

Returns:

true if the specified tab component is previewable, false otherwise.

isSensitiveToEvents

public boolean isSensitiveToEvents(javax.swing.JTabbedPane tabPane,
                                   int tabIndex)

Checks whether the specified tab component is sensitive to events. Overriding implementation may decide that disabled tabs do not respond to mouse and keyboard events, thus not allowing selecting the corresponding tab.

Parameters:

tabPane - Tabbed pane.

tabIndex - Tab index.

Returns:

true if the specified tab component is sensitive to events, false otherwise.

getPreviewDialogScreenBounds

public java.awt.Rectangle getPreviewDialogScreenBounds(javax.swing.JTabbedPane tabPane)

Returns the screen bounds of the tab preview dialog window.

Parameters:

tabPane - Tabbed pane.

Returns:

Screen bounds of the preview dialog window of the specified tabbed pane.

getModalOwner

public javax.swing.JFrame getModalOwner(javax.swing.JTabbedPane tabPane)

Returns the owner of the overview dialog of the specified tabbed pane. If this function retuns a non-null value, the overview dialog will be modal for the corresponding frame.

Parameters:

tabPane - Tabbed pane.

Returns:

If not null, the overview dialog for the specified tabbed pane will be modal for the corresponding frame.

hasOverviewDialog

public boolean hasOverviewDialog(javax.swing.JTabbedPane tabPane)

Checks whether the specified tabbed pane has an overview dialog.

Parameters:

tabPane - Tabbed pane.

Returns:

true if the specified tabbed pane has an overview dialog, false otherwise.

hasPreviewWindow

public boolean hasPreviewWindow(javax.swing.JTabbedPane tabPane,
                                int tabIndex)

Checks whether the specified tabbed pane has a preview window for the specified tab.

Parameters:

tabPane - Tabbed pane.

tabIndex - Tab index.

Returns:

true if the specified tabbed pane has a preview window for the specified tab, false otherwise.

getPreviewWindowDimension

public java.awt.Dimension getPreviewWindowDimension(javax.swing.JTabbedPane tabPane,
                                                    int tabIndex)

Returns the dimension for the tab preview window.

Parameters:

tabPane - Tabbed pane.

tabIndex - Tab index.

Returns:

Dimension of the tab preview window for the specified tab in the specified tabbed pane.

getPreviewWindowExtraDelay

public int getPreviewWindowExtraDelay(javax.swing.JTabbedPane tabPane,
                                      int tabIndex)

Returns extra delay (in milliseconds) for showing the tab preview window. The base delay is 2000 milliseconds (2 seconds). This function must return a non-negative value.

Parameters:

tabPane - Tabbed pane.

Returns:

Update cycle length in milliseconds for the thumbnail preview of the specified tabbed pane.

getOverviewKind

public LafConstants.TabOverviewKind getOverviewKind(javax.swing.JTabbedPane tabPane)
