Class TabState

java.lang.Object
  org.netbeans.swing.tabcontrol.plaf.TabState

Direct Known Subclasses:: BasicTabDisplayerUI.BasicTabState

public abstract class TabState
extends Object
extends Object

Used by BasicTabDisplayerUI and its subclasses. Tracks and manages the state of tabs, mainly which one currently contains the mouse, if the mouse is in the close button, if the tab is adjacent to a selected tab, if it is leftmost, rightmost, active, etc. This class hides most of the complexity of deciding what mouse events should trigger a repaint of what areas in an optimized way. It provides setters which a mouse listener can call to indicate that the mouse has, say, moved into a tab, or from one tab to another, or the selection has changed, etc.

Essentially, this class is fed indices of tabs that have various states (selected, contains mouse, etc.), figures out if this affects one tab, two tabs (a different tab had the state, such as the mouse moving from one tab to another) or all tabs (activated). It determines a change type, and consults a repaint policy (an integer bitmask) to decide if one, both, all or no tabs should be repainted.

The typical use case is to implement a subclass, and override getState() to mix in bitmasks for things like whether a tab is clipped, etc. - things the base implementation can't know about.

Subclasses implement the repaintTab() method to do the actual repainting, and implement getRepaintPolicy(). The repainting will be called if an event happens that changes the state in a way that the repaint policy bitmask indicates should cause a repaint.

BasicTabDisplayerUI implements a mouse listener which will call the appropriate methods when the mouse enters/exits tabs, etc.

Details

State is composed as an integer bitmask which covers all of the supported states of a tab that may affect the way they paint. These are also the values that are passed to the methods of a TabCellRenderer to tell it how to paint itself. Two other integer bitmasks are used: The changeType, which indicates whether a change was from one tab to another tab, one tab to no tab (i.e. selection set to -1), one tab to the same tab (i.e. the mouse moved out of the tab control, and so the tab with the mouse in it is now no tab). RepaintPolicy is an integer bitmask composed of conditions under which the control should repaint one or all tabs, and determines what types of changes actually trigger repaints.

Subclasses are expected to override getState() to provide information about non-mouse-or-focus related states, such as clipping of scrollable tabs. Predefined states for tabs are: CLIP_RIGHT, CLIP_LEFT, ARMED, PRESSED, SELECTED, ACTIVE, NOT_ONSCREEN, LEFTMOST, RIGHTMOST, CLOSE_BUTTON_ARMED, BEFORE_SELECTED, AFTER_SELECTED, MOUSE_IN_TABS_AREA, MOUSE_PRESSED_IN_CLOSE_BUTTON. Subclasses must handle returning the following states if they wish to, which are not handled directly in TabState: LEFTMOST, RIGHTMOST, CLIP_LEFT, CLIP_RIGHT, NOT_ONSCREEN.

Most of the states are fairly self-explanatory; NOT_ONSCREEN is useful as an optimization so that no work is done for events that would try to produce a repaint for something not visible; CLIP_* refers to the case in scrollable tab UIs, in which a tab may only be partially visible; MOUSE_PRESSED_IN_CLOSE_BUTTON is distinct because the CLOSE_BUTTON_ARMED state will be reset if the mouse moves out of the close button area, but UIs should perform a close action if the mouse was pressed over the close button, moved away from the close button and then back to it, so this state preserves the information that the originating location of a mouse press was in the close button.

Constructor Detail

TabState

public TabState()

Method Detail

getState

public int getState(int tab)

Get the state of a given tab. Subclasses are expected to override this to provide information about states such as clipping which can only be found out via layout information, such as LEFTMOST, RIGHTMOST, CLIP_LEFT and CLIP_RIGHT. The state is used by tab renderers to determine how they should paint themselves.

Parameters:: tab - The index of the tab
Returns:: The state

clearTransientStates

public void clearTransientStates()

Clear all mouse position related state information. This should be done following events in the model that alter the state sufficiently that the cached information is probably wrong.

setPressed

public final int setPressed(int i)

Set the index of the tab over which a mouse button has been pressed.

Parameters:: i - The tab which is pressed, or -1 to clear PRESSED from the state of the previously pressed tab
Returns:: Index of the tab which previously had the state PRESSED, or -1

setContainsMouse

public final int setContainsMouse(int i)

Set the index of the tab which currently contains the mouse cursor.

Parameters:: i - The tab which contains the mouse cursor, or -1 to clear ARMED from the state of the tab
Returns:: Index of the tab which previously had the state ARMED, or -1

setCloseButtonContainsMouse

public final int setCloseButtonContainsMouse(int i)

Set the index of the tab whose close button contains the mouse cursor.

Parameters:: i - The index of the tab whose close button contains the mouse cursor, or -1 to clear CLOSE_BUTTON_CONTAINS_MOUSE from the state of the tab which previously had it
Returns:: Index of the tab which formerly had the state CLOSE_BUTTON_CONTAINS_MOUSE, or -1

setMousePressedInCloseButton

public final int setMousePressedInCloseButton(int i)

Set the index of the tab in which the mouse button has been pressed in the close button. This is distinct from the combination of CLOSE_BUTTON_ARMED and PRESSED, since the user may press the close button and then drag away from the close button (clearing the CLOSE_BUTTON_ARMED state) to abort closing a tab.

Parameters:: i - The tab in which the mouse was pressed while over the close button
Returns:: Index of the tab which previously had the state MOUSE_PRESSED_IN_CLOSE_BUTTON, or -1

setSelected

public final int setSelected(int i)

Set the index of the tab which is currently selected. Note that users of this class must ensure that this value stays up to date when changes occur in the model such as inserting tabs before the selected one.

Parameters:: i - The tab index which is selected
Returns:: Index of the tab which previously was selected, or -1 if none

setMouseInTabsArea

public final boolean setMouseInTabsArea(boolean b)

Set the condition for all tabs of the mouse being in the tabs area.

Parameters:: b - Whether the mouse is in the tabs area or not
Returns:: The previous state with regard to the mouse being in the tabs area

setActive

public final boolean setActive(boolean b)

Set the condition for all tabs of the component being activated.

Parameters:: b - Whether or not the component is activated
Returns:: The previous state with regard to the component being activated

addAlarmTab

public final void addAlarmTab(int alarmTab)

Add a tab to the list of those which should "flash" or otherwise give some notification to the user to get their attention

removeAlarmTab

public final void removeAlarmTab(int alarmTab)

Remove a tab to the list of those which should "flash" or otherwise give some notification to the user to get their attention

possibleChange

protected void possibleChange(boolean prevVal,
                              boolean currVal,

public String toString()

Overrides:: toString in class Object

change

protected void change(int lastTab,
                      int currTab,
                      int type,
                      int changeType)

Called when a setter for a tab index has produced a change in a state-affecting property, such as which tab contains the mouse. Fetches the repaint policies, and if the change is one that the policy says should produce a repaint, calls repaintTab for the appropriate tabs.

Parameters:: lastTab - The tab previously holding the state which has changed, or -1; currTab - The tab currently holding the state which has changed, or -1; type - The thing that changed. This will be one of the state constants.; changeType - This is one of the defined change types such as ALL_TABS, TAB_TO_TAB, etc.

maybeRepaint

protected void maybeRepaint(int tab,
                            int type)

repaintTab

protected abstract void repaintTab(int tab)

repaintAllTabs

protected abstract void repaintAllTabs()

getRepaintPolicy

public abstract int getRepaintPolicy(int tab)

Get the repaint policy that will be used to determine what tabs to repaint, based on state changes. The default implementation in BasicTabDisplayerUI simply ignores the tab argument and returns a single policy for all tabs created in BasicTabDisplayerUI.createRepaintPolicy()

Parameters:: tab - Index of tab in question
Returns:: Type of repaint policy for given tab
