Description
Interface Summary | |
Adjustable | The interface for objects that have an adjustable numeric value constrained within a bounded range of values. |
ItemSelectable | The interface for objects that contain a set of items, one or more of which can be selected. |
LayoutManager | Defines the interface for classes that know how to lay out Containers. |
LayoutManager2 | Defines an interface for classes that know how to lay out a Container based on a layout-constraints object. |
Scrollable | The interface for objects that can be contained in a ScrollPane and scrolled within a Viewport. |
Class Summary | |
BorderLayout | A concrete implementation of LayoutManager that lays out its components around its edges. |
Color | A class used to represent the color values available on a text terminal. |
ColorPair | This class is used to represent a color-pair (a combination of a foreground color and a background color). |
Component | Component is the abstract superclass of all the other CHARVA widgets. |
Container | Container is the abstract superclass of Window and Panel. |
Dialog | The Dialog class is similar to a Frame but includes a blank area around the border frame. |
Dimension | Encapsulates the width and height of a component in a single object. |
EventQueue | The EventQueue class queues "AWT" events, which are used to trigger drawing actions. |
FlowLayout | A concrete implementation of LayoutManager that lays out its components left-to-right. |
Font | The Font class in the CHARVA package exists for "compatibility" with AWT; the only useful information it holds is whether the style is BOLD or not. |
Frame | A Frame is a top-level window with a title and a border. |
GridBagConstraints | This class defines constraints used for laying out components in the GridBagLayout layout manager. |
GridBagLayout | This is an approximation of the AWT GridBagLayout layout manager. |
Insets | The Insets class specifies the blank space that must be left around the inside of the edges of a Container. |
PlaybackThread | This class reads a scriptfile line by line, parses each line into a keystroke-specifier and a time-interval, and fires the specified keystroke after the specified delay. |
Point | Represents a point in (x,y) coordinate space, with integer precision. |
Rectangle | The Rectangle class respresents a rectangular area of the screen; the boundaries are INCLUSIVE (i.e. the _right instance variable refers to the rightmost column that is included in the rectangular area, and the _bottom instance variable refers to the bottom row that is included in the rectangle. |
ShutdownHook | This class is used to clean up the ncurses environment and restore the terminal settings when the application terminates, whether the program exits intentionally or because of a signal such as SIGTERM, SIGHUP etc. |
Toolkit | The Toolkit class provides the interface to the "ncurses" library functions. |
Window | The Window class represents a "toplevel" window with no decorative frame. |
Exception Summary | |
IllegalComponentStateException | This exception is thrown when a CHARVA component is in an illegal state for the requested operation. |
TerminfoCapabilityException | This exception is thrown by the Toolkit class when it cannot find a requested capability in the terminfo database (or when it finds the requested capability but it is of the wrong type). |
Provides the base classes and interfaces for the CHARVA Text User Interface.
