List of all members.


Detailed Description

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.
