Constructor Detail

BasicScrollingTabDisplayerUI

public BasicScrollingTabDisplayerUI(TabDisplayer displayer)

Creates a new instance of BasicScrollingTabDisplayerUI

Method Detail

createLayoutModel

protected final TabLayoutModel createLayoutModel()

Description copied from class: AbstractTabDisplayerUI

Create an instance of TabLayoutModel which will provide coordinates for tabs

Specified by:

createLayoutModel in class AbstractTabDisplayerUI

---

createTabState

protected TabState createTabState()

Description copied from class: BasicTabDisplayerUI

Create a TabState instance. TabState manages the state of tabs - that is, which one contains the mouse, which one is pressed, and so forth, providing methods such as setMouseInTab(int tab). Its getState() method returns a bitmask of states a tab may have which affect the way it is painted.

Usage: It is expected that UIs will subclass TabState, to implement the repaint methods, and possibly override getState(int tab) to mix additional state bits into the bitmask. For example, scrollable tabs have the possible states CLIP_LEFT and CLIP_RIGHT; BasicScrollingTabDisplayerUI's implementation of this determines these states by consulting its layout model, and adds them in when appropriate.

Overrides:

createTabState in class BasicTabDisplayerUI

Returns:

An implementation of TabState

See Also:

BasicTabDisplayerUI.BasicTabState, BasicScrollingTabDisplayerUI.ScrollingTabState

---

createHierarchyListener

protected HierarchyListener createHierarchyListener()

Overrides:

createHierarchyListener in class AbstractTabDisplayerUI

---

makeTabVisible

public void makeTabVisible(int tab)

Description copied from class: TabDisplayerUI

Instruct the UI to ensure that the tab at the given index is visible. Some UIs allow scrolling or otherwise hiding tabs. The default implementation is a no-op.

Overrides:

makeTabVisible in class TabDisplayerUI

Parameters:

tab - The index of the tab that should be made visible, which should be within the range of 0 to the count of tabs in the model

---

getTabsAreaWidth

protected final int getTabsAreaWidth()

Returns the width of the tabs area

---

getTabAreaInsets

public Insets getTabAreaInsets()

Description copied from class: BasicTabDisplayerUI

Return a set of insets defining the margins into which tabs should not be painted. Subclasses that want to paint some controls to the right of the tabs should include space for those controls in these insets. If a bottom margin under the tabs is to be painted, include that as well.

Specified by:

getTabAreaInsets in class BasicTabDisplayerUI

---

getLastVisibleTab

protected final int getLastVisibleTab()

Description copied from class: BasicTabDisplayerUI

Scrollable implementations will override this method to provide the last visible (even if clipped) tab. The default implementation returns 0 if there is at least one tab in the data model, or -1 to indicate the model is completely empty

Overrides:

getLastVisibleTab in class BasicTabDisplayerUI

---

getFirstVisibleTab

protected final int getFirstVisibleTab()

Description copied from class: BasicTabDisplayerUI

Scrollable implementations will override this method to provide the first visible (even if clipped) tab. The default implementation returns 0 if there is at least one tab in the data model, or -1 to indicate the model is completely empty

Overrides:

getFirstVisibleTab in class BasicTabDisplayerUI

---

install

protected void install()

Description copied from class: BasicTabDisplayerUI

Overridden to initialize the tabState and defaultRenderer.

Overrides:

install in class BasicTabDisplayerUI

---

uninstall

protected void uninstall()

Description copied from class: AbstractTabDisplayerUI

Called after uninstalling the mouse listener and selection model, but before references to that or the layout model or displayer have been nulled. Subclasses may use this method to do any cleanup they need to do at uninstall time.

Overrides:

uninstall in class BasicTabDisplayerUI

---

createLayout

protected LayoutManager createLayout()

---

getControlButtons

protected Component getControlButtons()

Returns:

A component that holds control buttons (scroll left/right, drop down menu) that are displayed to right of the tab area.

---

createComponentListener

protected ComponentListener createComponentListener()

Description copied from class: AbstractTabDisplayerUI

Create a ComponentListener that may be needed to handle resize, show, hide, etc. Returns null by default.

Overrides:

createComponentListener in class AbstractTabDisplayerUI

---

modelChanged

protected void modelChanged()

Overrides modelChanged() to clear the transient information in the state model, which may now contain tab indices that don't exist, and also to clear cached width/last-visible-tab data in the layout model, and ensure that the selected tab is visible.

Overrides:

modelChanged in class BasicTabDisplayerUI

---

installControlButtons

protected void installControlButtons()

---

getMinimumSize

public Dimension getMinimumSize(JComponent c)

Overrides:

getMinimumSize in class ComponentUI

---

scroll

protected final ScrollingTabLayoutModel scroll()

Convenience getter for the layout model as an instance of ScrollingTabLayoutModel

---

processMouseWheelEvent

protected void processMouseWheelEvent(MouseWheelEvent e)

Overridden to update the offset of the ScrollingTabLayoutModel on mouse wheel events

Overrides:

processMouseWheelEvent in class BasicTabDisplayerUI

---

getOffscreenGraphics

public static Graphics2D getOffscreenGraphics()

Provides an offscreen graphics context so that widths based on character size can be calculated correctly before the component is shown

---

getControlButtonsRectangle

protected Rectangle getControlButtonsRectangle(Container parent)

Returns:

Bounds for the control buttons in the tab displayer container.
