Constructor Detail

AbstractSplitPanel

public AbstractSplitPanel()

Method Detail

addComponent

public void addComponent(Component c)

Add a component into this container. The component is added to the right or under the previous component.

Specified by:

addComponent in interface ComponentContainer

Overrides:

addComponent in class AbstractComponentContainer

Parameters:

c - the component to be added.

See Also:

ComponentContainer.addComponent(Component)

setFirstComponent

public void setFirstComponent(Component c)

Sets the first component of this split panel. Depending on the direction the first component is shown at the top or to the left.

Parameters:

c - The component to use as first component

setSecondComponent

public void setSecondComponent(Component c)

Sets the second component of this split panel. Depending on the direction the second component is shown at the bottom or to the left.

Parameters:

c - The component to use as first component

getFirstComponent

public Component getFirstComponent()

Gets the first component of this split panel. Depending on the direction this is either the component shown at the top or to the left.

Returns:

the first component of this split panel

getSecondComponent

public Component getSecondComponent()

Gets the second component of this split panel. Depending on the direction this is either the component shown at the top or to the left.

Returns:

the second component of this split panel

removeComponent

public void removeComponent(Component c)

Removes the component from this container.

Specified by:

removeComponent in interface ComponentContainer

Overrides:

removeComponent in class AbstractComponentContainer

Parameters:

c - the component to be removed.

See Also:

ComponentContainer.removeComponent(Component)

getComponentIterator

public Iterator<Component> getComponentIterator()

Description copied from interface: HasComponents

Gets an iterator to the collection of contained components. Using this iterator it is possible to step through all components contained in this container.

Returns:

the component iterator.

getComponentCount

public int getComponentCount()

Gets the number of contained components. Consistent with the iterator returned by getComponentIterator().

Returns:

the number of contained components (zero, one or two)

replaceComponent

public void replaceComponent(Component oldComponent,
                             Component newComponent)

Description copied from interface: ComponentContainer

Replaces the component in the container with another one without changing position.

This method replaces component with another one is such way that the new component overtakes the position of the old component. If the old component is not in the container, the new component is added to the container. If the both component are already in the container, their positions are swapped. Component attach and detach events should be taken care as with add and remove.

Parameters:

oldComponent - the old component that will be replaced.

newComponent - the new component to be replaced.

setSplitPosition

public void setSplitPosition(float pos)

Moves the position of the splitter.

Parameters:

pos - the new size of the first region in the unit that was last used (default is percentage). Fractions are only allowed when unit is percentage.

setSplitPosition

public void setSplitPosition(float pos,
                             boolean reverse)

Moves the position of the splitter.

Parameters:

pos - the new size of the region in the unit that was last used (default is percentage). Fractions are only allowed when unit is percentage.

reverse - if set to true the split splitter position is measured by the second region else it is measured by the first region

setSplitPosition

public void setSplitPosition(float pos,
                             Sizeable.Unit unit)

Moves the position of the splitter with given position and unit.

Parameters:

pos - the new size of the first region. Fractions are only allowed when unit is percentage.

unit - the unit (from Sizeable) in which the size is given.

setSplitPosition

public void setSplitPosition(float pos,
                             Sizeable.Unit unit,
                             boolean reverse)

Moves the position of the splitter with given position and unit.

Parameters:

pos - the new size of the first region. Fractions are only allowed when unit is percentage.

unit - the unit (from Sizeable) in which the size is given.

reverse - if set to true the split splitter position is measured by the second region else it is measured by the first region

getSplitPosition

public float getSplitPosition()

Returns the current position of the splitter, in getSplitPositionUnit() units.

Returns:

position of the splitter

getSplitPositionUnit

public Sizeable.Unit getSplitPositionUnit()

Returns the unit of position of the splitter

Returns:

unit of position of the splitter

setLocked

public void setLocked(boolean locked)

Lock the SplitPanels position, disabling the user from dragging the split handle.

Parameters:

locked - Set true if locked, false otherwise.

isLocked

public boolean isLocked()

Is the SplitPanel handle locked (user not allowed to change split position by dragging).

Returns:

true if locked, false otherwise.

addListener

public void addListener(AbstractSplitPanel.SplitterClickListener listener)

removeListener

public void removeListener(AbstractSplitPanel.SplitterClickListener listener)

getState

public AbstractSplitPanelState getState()

Description copied from class: AbstractComponent

Returns the shared state bean with information to be sent from the server to the client. Subclasses should override this method and set any relevant fields of the state returned by super.getState().

Specified by:

getState in interface Connector

Specified by:

getState in interface Component

Overrides:

getState in class AbstractComponent

Returns:

updated component shared state
