public class LimitControlPanel
extends javax.swing.JPanel
implements InputObject, Tieable, Limits, java.awt.event.ActionListener

A LimitControlPanel has four input boxes for specifying the xmin, xmax, ymin, and ymax of a CoodinateRect. You can actually add more than one CoordinteRect to the LimitControlPanel. This will synchronize the coordinate systems on the all the CoordinateRects that is controlls.

A LimitControlPanel can also contain a number of standard buttons, such as buttons for zooming the coordinates in and out. The buttons are specfied using constants defined in this class. It is possible to obtain standard buttons so that they can be displayed outside the LimitControlPanel. Furthermore, it is also possible to add other components to the panel, using the addRange(), addComponent(), and addComponentPair() methods. (The standard add() method from the Component class is overridded to call addComponent().) Any VariableInput added to the LimitControl Panel will appear with its name as a label, just above the input box.

Ordinarily, all the components are just stacked up vertically. However, if you set the useTwoColumnsIfPossible property to true, then they will be in two columns, unless the width of the Panel is too small for two columns. Pairs of items added with addRange() or addComponentPair() will appear on the same row. An item added with addComponent() will appear on a row by itself. As for the standard buttons, the following pairs will appear together, IF they are added at the same time: SET_LIMITS and EQUALUIZE; ZOOM_IN and ZOOM_OUT; SAVE and RESTORE.

A LimitControlPanel can have an error reporter, which is used to report any errors that are found in the input boxes for xmin, xmax, ymin, ymax (or other VariableInputs added with addRange()). Except for these input boxes, other coponents are NOT checked for errors.

useTwoColumnsIfPossible - If this is true, then the components in the panel will be arranged into two columns instead of one (assuming that there is room).

LimitControlPanel

public LimitControlPanel(java.lang.String xminName,
                         java.lang.String xmaxName,

Method Detail

addCoords

public void addCoords(CoordinateRect coords)

Add a CoordinateRect to be controlled by this LimitControlPanel. When the user changes the limits in this LimitControlPanel, the limits are also changed on the CoordinateRect to match. If the limits on the CoordinateRect change for some other reason, then the limits in the panel are changed to match. If multiple CoordinateRects are added, the limits on all the CoordinateRects will be synchronized with each other and with the limits in the panel.

Parameters:

coords - the CoordinateRect to be controlled

addCoords

public void addCoords(DisplayCanvas canvas)

Add the first CoordinateRect from the canvas to be controlled by this LimitControlPanel. (Just calls addCoords(canvas.getCoordinateRect()).)

Parameters:

canvas - the DisplayCanvas to get the CoordinateRect from

setErrorReporter

public void setErrorReporter(ErrorReporter rep)

Set the ErrorReporter that is used to report errors in the user's input. Note that only the input boxes for xmin, xmax, ymin, and ymax and any VariableInputs added with the addRange() method are checked.

Parameters:

rep - the error reporter to use

getErrorReporter

public ErrorReporter getErrorReporter()

Get the ErrorReporter that is used to report errors in the user's input. Note that only the input boxes for xmin, xmax, ymin, and ymax and any VariableInputs added with the addRange() method are checked.

Returns:

the error reporter being used

setUseTwoColumnsIfPossible

public void setUseTwoColumnsIfPossible(boolean two)

Set to true if you want the components to be shown in two columns (provided the panel is wide enough).

Parameters:

two - true or false

getUseTwoColumnsIfPossible

public boolean getUseTwoColumnsIfPossible()

Get the value of the "useTwoColumnsIfPossible" property of this panel.

Returns:

true or false

addAnimator

public void addAnimator(Animator animator)

pkhg 050430

Parameters:

animator -

addComponent

public void addComponent(javax.swing.JComponent c)

Add a component to the panel. If two-column format is used, it will be shown on a line by itself. Note that the component shouldn't be too wide, or it will make the Panel stretch. This component is NOT checked for input errors. If it is an input object or a computable, it should be added to a Controller. For an input object, some Controller should be set up to be notified when the value changes. (You have to do this by hand, even if you use WcmPanels!!)

Parameters:

c - component to add to panel

addComponentPair

public void addComponentPair(javax.swing.JComponent c1,
                             javax.swing.JComponent c2)

Add two components to the panel. If two-column format is used, they will be shown on the same row. Note that the components shouldn't be too wide, or they will make the Panel stretch. These components are NOT checked for input errors. If they are input objects or computables, they should be added to another Controller. For an input object, some Controller should be set up to be notified when the value changes. (You have to do this by hand, even if you use JCMPanels!!)

Parameters:

c1 - component to add to panel

c2 - component to add to panel

addRange

public void addRange(VariableInput v1,
                     VariableInput v2)

Add two VariableInputs to the panel. These ARE checked for input when the user presses return or clicks the SET_LIMITS button. Furthermore, it is checked that the value in the second input box is greater than the value in the first, and an error is reported if it is not. This method is used to add the xmin, xmax, ymin, and ymax boxes. It could possibly be used to add tmin and tmax boxes for the limits on the parameter of a parametric curve, for example.

Parameters:

v1 - VariableInput to add to panel

v2 - VariableInput to add to panel

addButtons

public void addButtons(int buttonSet)

Add the buttons in buttonSet to the panel, if they are not already there. buttonSet should be formed by or-ing together some of the constants SET_LIMITS, ZOOM_IN, etc.

Parameters:

buttonSet - buttons to add to panel

getButtonOptions

protected int getButtonOptions()

Get the button options; meant to be used only by WCMLimitControlPanelBean

Returns:

the buttons (encoded in an int)

getButton

public javax.swing.JButton getButton(int buttonCode)

Get a Button corresponding to one of the six button types defined by the constants SET_LIMITS, EQUALIZE, ZOOM_IN, ZOOM_OUT, SAVE, and RESTORE in this class. The button can be added to a different panel, but it will still affect this LimitControlPanel in the usual way. It is possible to change the name of the button, and it will still work correctly. Each call to this method creates a new button, even if multiple buttons of the same type are created.

Parameters:

buttonCode - one of the constants from this class (SET_LIMITS, EQUALIZE, etc.) specifying one of the types of button for controlling limits. If the parameter is not one of these constants, and IllegalArgumentException will be thrown.

Returns:

the desired button

add

Redefine this method from the JComponent class to make it a synonym for addComponent(c);

Parameters:

c - component to add

Returns:

the component added
