Class PanelSplitter

All Implemented Interfaces:

public class PanelSplitter

extends Control

You should not use this directly except to set properties such as the thickness and arrow direction. Instead use a SplittablePanel to get two empty CellPanels with a splitter between them. Then you can configure how the panel operates using SplittablePanel.setSplitter().

Method Detail

setOpenCloseTypes

public PanelSplitter setOpenCloseTypes(int openType,
                                       int closeType)

doOpenClose

public void doOpenClose(boolean open)

Open or close the splitter. Opening is a movement to the right or downwards. The limits of the open or close is defined by the openType and closeType values.

Parameters:

open - if this is true then an open will be performed, otherwise a close will be performed.

calculateSizes

public void calculateSizes()

Description copied from class: Control

Override this to calculate the preferred, minimum and maximum size of your control. This is only called once unless the modifier flag AlwaysRecalculateSizes is true. During the calculation you will set the variables preferredWidth, preferredHeight, etc. directly.

Overrides:

calculateSizes in class Control

doPaint

public void doPaint(Graphics g,
                    Rect area)

Overrides:

doPaint in class Control

changeIt

public void changeIt(int change)

checkLimits

protected void checkLimits()

penPressed

public void penPressed(Point where)

Description copied from class: Control

Called when the Pen or Mouse button is pressed on the control. This is called by the onPenEvent(PenEvent ev) method.

Within this method you can use the Control.currentPenEvent value to find out more about the PenEvent that caused this - including any modifiers (e.g. SHIFT keys) or determine if the left or right mouse button was pressed.

Overrides:

penPressed in class Control

Parameters:

where - The point on the Control where the pen was pressed.

showPreferredSize

public void showPreferredSize(Control ex)

resize

public void resize(int toWhat)

penClicked

public void penClicked(Point where)

Description copied from class: Control

Called if the Pen or Mouse button is quickly pressed and released. This is called by the onPenEvent(PenEvent ev) method.

Within this method you can use the Control.currentPenEvent value to find out more about the PenEvent that caused this - including any modifiers (e.g. SHIFT keys) or determine if the left or right mouse button was pressed.

By default this method simply calls the penReleased() method.

Overrides:

penClicked in class Control

Parameters:

where - The point on the Control where the pen was clicked.

startDragging

public void startDragging(DragContext dc)

Description copied from class: Control

This is called to indicate the start of a pen/mouse drag operation. This will only get called if the WantDrag modifier has been set for this control. Within this method you can call startDragAndDrop() or tryDragAndDrop() to begin a data DragAndDrop operation.

Overrides:

startDragging in class Control

Parameters:

dc - A DragContext indicating information about the dragging.

stopDragging

public void stopDragging(DragContext dc)

Description copied from class: Control

Called when the pen was released during a drag operation. This will only be called if a data DragAndDrop was not initiated and if the cancelled member of the DragContext was not set true during the operation.

Overrides:

stopDragging in class Control

Parameters:

dc - The DragContext for the dragging operation.

dragged

public void dragged(DragContext dc)

Description copied from class: Control

This is called during the drag operation. It is also called by default by the startDragging() method if you do not override it.

Overrides:

dragged in class Control

Parameters:

dc - The DragContext for the dragging operation.
