Tells whether this CDockable can be minimized by the user.

Returns:

true if this element can be minimized

isMaximizable

boolean isMaximizable()

Tells whether this CDockable can be maximized by the user.

Returns:

true if this element can be maximized

isExternalizable

boolean isExternalizable()

Tells whether this CDockable can be externalized by the user.

Returns:

true if this element can be externalized

isNormalizeable

boolean isNormalizeable()

Tells whether this CDockable can be normalized by the user. Usually this method should return true for any dockable, as "normalizing" is the default mode.
Clients should not override this method.

Returns:

true, unless a subclass requires very special behavior.

isStackable

boolean isStackable()

Tells whether this CDockable can be combined with another Dockable to create a stack.

Returns:

true if this element can be combined with another Dockable, normally true should be the answer.

isCloseable

boolean isCloseable()

Tells whether this CDockable can be closed by the user. A close-button has to be provided by the CDockable itself. The best way to do that is to instantiate a CloseActionSource and include this source in the array that is returned by CommonDockable.getSources().

Returns:

true if this element can be closed

isResizeLockedVertically

boolean isResizeLockedVertically()

Tells whether the height of this CDockable should remain the same when its parent changes the size. This has only effect if the parent can choose the size of its children. A lock is no guarantee for staying with the same size, the user still can resize this CDockable.

Returns:

true if the height of this CDockable should remain the same during resize events of the parent.

isResizeLockedHorizontally

boolean isResizeLockedHorizontally()

Tells whether the width of this CDockable should remain the same when its parent changes the size. This has only effect if the parent can choose the size of its children. A lock is no guarantee for staying with the same size, the user still can resize this CDockable.

Returns:

true if the width of this CDockable should remain the same during resize events of the parent.

getAndClearResizeRequest

RequestDimension getAndClearResizeRequest()

Gets the preferred size of this CDockable. The preferred size will be used to resize this CDockable when CControl.handleResizeRequests() is called. There are no guarantees that the request can be granted, or will be handled at all.
Calling this method should delete the request, so calling this method twice should have the effect, that the second time null is returned.

Returns:

the next requested size or null

setVisible

void setVisible(boolean visible)

Shows or hides this CDockable. If this CDockable is not visible and is made visible, then the framework tries to set its location at the last known position.
Subclasses should call CControlAccess.show(CDockable) or CControlAccess.hide(CDockable).

Parameters:

visible - the new visibility state

Throws:

IllegalStateException - if this dockable can't be made visible

See Also:

isVisible()

isVisible

boolean isVisible()

Tells whether this CDockable is currently visible or not. Visibility means that this CDockable is in the tree structure of DockingFrames and has a parent. Being in the structure does not imply being visible on the screen: If some JFrame is not shown, or some DockStation not properly added to a parent component, then a visible CDockable can be invisible for the user. For CDockables that are also root-CStation this method will always return true.
Clients interested in whether the user can actually see this dockable should call isShowing().
Subclasses should return the result of CControlAccess.isVisible(CDockable).

Returns:

true if this CDockable can be accessed by the user through a graphical user interface.

See Also:

hasParent(), isShowing()

hasParent

boolean hasParent()

Tells whether this CDockable has a root station as parent. Having a root station as parent implies isVisible(). For root-CStation this method will return false if they do not have a parent, they are not considered to be parents of themselves.
Subclasses should return the result of CControlAccess.hasParent(CDockable).

Returns:

true if this dockable has a parent and is in the tree

isDockableVisible

@Deprecated
@Todo(compatibility=BREAK_MAJOR,
      priority=ENHANCEMENT,
      target=VERSION_1_1_3,
      description="remove this method")
boolean isDockableVisible()

Deprecated. this method gets replaced by isShowing(), which offers the exact same information. This method will be removed in a future release

Tells whether this CDockable is currently visible to the user. A CDockable which is not visible, is not dockable visible either. The method does not take into account that a frame may be positioned such that it is not entierly visible on the screen. Neither does the method take into account, that a frame may be minimized.

Returns:

true if the user should be able to see this item

isShowing

boolean isShowing()

Tells whether this CDockable is currently visible to the user. A CDockable which is not visible, is not showing either. The method does not take into account that a frame may be positioned such that it is not entierly visible on the screen. The method may or may not take into account, that a frame may be minimized.
Clients interested in monitoring this property can add a CDockableLocationListener to this dockable.

Returns:

true if the user should be able to see this item

See Also:

CDockableLocationListener, addCDockableLocationListener(CDockableLocationListener)

setLocation

void setLocation(CLocation location)

Sets the location of this CDockable. If this CDockable is visible, than this method will take immediately effect. Otherwise the location will be stored in a cache and read as soon as this CDockable is made visible.
Note that the location can only be seen as a hint, the framework tries to fit the location as good as possible, but there are no guarantees.
Subclasses should call CControlAccess.getLocationManager() and CLocationModeManager.setLocation(bibliothek.gui.Dockable, CLocation).

Parameters:

location - the new location, null is possible, but will not move the CDockable immediately

See Also:

getBaseLocation()

setLocationsAside

void setLocationsAside(CDockable dockable)

Sets the location of this CDockable aside dockable in all ExtendedModes. If this Dockable is visible, then it may or may not change its location and ExtendedMode. Note that dockable and this must not be the same object, and that both CDockables must be registered at a CControl.

Parameters:

dockable - the item whose locations should be copied

Throws:

IllegalArgumentException - if dockable is null, not registered, the same as this, or has a different working area

IllegalStateException - if this is not registered at the same CControl as dockable

setLocationsAside

boolean setLocationsAside(Filter<CDockable> filter)

Traverses the history of focused CDockables, and selects the newest item with focus and matching filter for calling setLocationsAside(CDockable).

Parameters:

filter - to select a CDockable which did have the focus

Returns:

true if an old focused Dockable was found, false if not

setLocationsAsideFocused

boolean setLocationsAsideFocused()

Searches for the last focused CDockable with the same working area as this, and calls setLocationsAside(CDockable) with it.
Note that if this dockable is visible, then it may or may not change its location. This method should be called before making the dockable visible.

Returns:

true if the last focused CDockable was found, false otherwise. If false then no action was performed

getBaseLocation

CLocation getBaseLocation()

Gets the location of this CDockable. If this CDockable is visible, then a location will always be returned. Otherwise a location will only be returned if it just was set using setLocation(CLocation).

Returns:

the location or null

getAutoBaseLocation

CLocation getAutoBaseLocation(boolean noBackwardsTransformation)

Tries to find out at which location this CDockable may appear if it would be made visible. The default implementation of this method has severe limitations:

• Random placements are not considered and the result will be null
• Placeholders are not considered, if this CDockable is associated with a placeholder, then the placeholder information will be completely lost.
• This CDockable must not be visible and it must be registered at a CControl.

To be more precise: the location returned by this method may not be the actual location where this dockable appears because this method does not consider all circumstances.
Clients can make use of this method in two ways:

• They can find out whether the dockable has a location, or will be placed randomly (in which case the result of this method is null)
• They can override this method in which case the CDockable will appear at the exact location that is returned by this method ignoring any other settings.

Parameters:

noBackwardsTransformation - if true, then this method should not convert any DockableProperty back to a CLocation, instead it should return null if such a conversion would be necessary. This way the method does return null in any case where information (e.g. placeholders) could be lost due to the limitations of CLocation

Returns:

The expected location of this invisible CDockable, this may either be the location that was set by calling setLocation(CLocation), the last location of this dockable when it was visible, the default location of the CControl or the default location for the normalized extended mode. A value of null is returned if this CDockable would appear at a random location, is not registered at a CControl or is already visible.

setExtendedMode

void setExtendedMode(ExtendedMode extendedMode)

Sets how and where this CDockable should be shown. Conflicts with isExternalizable(), isMaximizable() and isMinimizable() will just be ignored. Implementations should call LocationModeManager.setMode(Dockable, ExtendedMode).
If this dockable is not visible, then it will be made visible in order to apply the extendedMode.

Parameters:

extendedMode - the size and location

getExtendedMode

ExtendedMode getExtendedMode()

Gets the size and location of this CDockable. Implementations should return LocationModeManager.getMode(Dockable).

Returns:

the size and location or null if this CDockable is not part of an CControl. May be null if this dockable is not visible.

getGrouping

DockableGrouping getGrouping()

Gets an algorithm that tells how this CDockable attempts to group itself automatically with other Dockables. The algorithm is able to rewrite the location of this CDockable everytime when it is moved to a new location, assuming that no stronger mechanism, or the user, already defined a location.

Returns:

the grouping behavior, or null

setWorkingArea

void setWorkingArea(CStation<?> area)

Sets the parent of this CDockable. This method can be called by the client or indirectly through setLocation(CLocation).

Parameters:

area - the new parent or null
