Class AbstractViewTabDisplayerUI

java.lang.Object

      org.netbeans.swing.tabcontrol.TabDisplayerUI
          org.netbeans.swing.tabcontrol.plaf.AbstractViewTabDisplayerUI

public abstract class AbstractViewTabDisplayerUI
extends TabDisplayerUI

Basic UI class for view tabs - non scrollable tabbed displayer, which shows all tabs equally sized, proportionally. This class is independent on specific L&F, acts as base class for specific L&F descendants.

XXX eventually this class should be deleted and a subclass of BasicTabDisplayer can be used; currently this is simply a port of the original code to the new API. Do not introduce any new subclasses of this.

getExactTabIndication

public Polygon getExactTabIndication(int index)

Description copied from class: TabDisplayerUI

Get a shape representing the exact outline of the numbered tab. The implementations in the package will return instances of EqualPolygon from this method; other implementations may return what they want, but for performance reasons, it is highly desirable that the shape object returned honor equals() and hashCode(), as there are significant optimizations in NetBeans' drag and drop support that depend on this.

Specified by:

getExactTabIndication in class TabDisplayerUI

---

getInsertTabIndication

public Polygon getInsertTabIndication(int index)

Description copied from class: TabDisplayerUI

Get a shape representing the area of visual feedback during a drag and drop operation, which represents where a tab will be inserted if a drop operation is performed over the indicated tab.

The implementations in the package will return instances of EqualPolygon from this method; other implementations may return what they want, but for performance reasons, it is highly desirable that the shape object returned honor equals() and hashCode(), as there are significant optimizations in NetBeans' drag and drop support that depened on this.

Specified by:

getInsertTabIndication in class TabDisplayerUI

Returns:

Shape representing feedback shape

---

createImageOfTab

public Image createImageOfTab(int index)

Paints the rectangle occupied by a tab into an image and returns the result

Overrides:

                            Rectangle destination)

Description copied from class: TabDisplayerUI

Configure the passed rectangle with the shape of the tab at the given index.

Specified by:

getTabRect in class TabDisplayerUI

---

tabForCoordinate

public int tabForCoordinate(Point p)

Description copied from class: TabDisplayerUI

Returns the index of the tab at the passed point, or -1 if no tab is at that location. Note that this method may return -1 for coordinates which are within a tab as returned by getTabRect(), but are not within the visible shape of the tab as the UI paints it.

Specified by:

tabForCoordinate in class TabDisplayerUI

---

createRepaintPolicy

protected int createRepaintPolicy()

---

isAttention

protected boolean isAttention(int tab)
