## Detailed Description

This is a plugin that can handle keyboard input and display it on an associated console.

The plugin has a command history and when user presses 'Enter' can call some callback function to execute the entered command.

WARNING Do NOT use the event handler that may (or may not) be implemented by the console and register that to the event queue. This doesn't work properly. Instead register your own event handler and call HandleEvent() from that.

Main creators of instances implementing this interface:

- Standard input console plugin (crystalspace.console.input.standard)

- csQueryRegistry()

## Member Function Documentation

virtual void iConsoleInput::Bind | ( | iConsoleOutput * | console | ) | `[pure virtual]`

Bind to an output console.

Parameters:

  | console |

virtual void iConsoleInput::Clear | ( |  | ) | `[pure virtual]`

| Clear the history buffer.

virtual int iConsoleInput::GetBufferSize | ( |  | ) | const`[pure virtual]`

| Retrieve the size of the history buffer.

virtual int iConsoleInput::GetCurLine | ( |  | ) | const`[pure virtual]`

| Return the current input line number.

virtual iConsoleExecCallback* iConsoleInput::GetExecuteCallback | ( |  | ) | `[pure virtual]`

| Get the command execution callback.

virtual const char* iConsoleInput::GetText | ( | int | line = `-1` | ) | const`[pure virtual]`

Return a line from the input buffer.

Parameters:

  | line | is the line number to get or -1 (default) for current line.

virtual bool iConsoleInput::HandleEvent | ( | iEvent & |  | ) | `[pure virtual]`

| Handle a console-related event. Do NOT use the event handler that may (or may not) be implemented by the console and register that to the event queue. This doesn't work properly. Instead register your own event handler and call HandleEvent() from that.

virtual void iConsoleInput::SetBufferSize | ( | int | size | ) | `[pure virtual]`

Set the size of the history buffer.

Parameters:

  | size | is the size in lines of the history buffer.

virtual void iConsoleInput::SetExecuteCallback | ( | iConsoleExecCallback * | callback | ) | `[pure virtual]`

Set the command execution callback.

Parameters:

  | callback | will be called whenever the user presses enter so the application can then perform the command that was entered.

virtual void iConsoleInput::SetPrompt | ( | const char * | prompt | ) | `[pure virtual]`

| Set the prompt string.
