Specified by:

getFontHeight in class GraphicalTerminalImplementation

Returns:

Terminal font height in pixels

getFontWidth

protected int getFontWidth()

Description copied from class: GraphicalTerminalImplementation

Used to find out the font width, in pixels

Specified by:

getFontWidth in class GraphicalTerminalImplementation

Returns:

Terminal font width in pixels

getHeight

protected int getHeight()

Description copied from class: GraphicalTerminalImplementation

Used when requiring the total height of the terminal component, in pixels

getHeight in class GraphicalTerminalImplementation

Returns:

Height of the terminal component, in pixels

getWidth

protected int getWidth()

Description copied from class: GraphicalTerminalImplementation

Used when requiring the total width of the terminal component, in pixels

getWidth in class GraphicalTerminalImplementation

Returns:

Width of the terminal component, in pixels

getFontForCharacter

protected Font getFontForCharacter(TextCharacter character)

Description copied from class: GraphicalTerminalImplementation

Returning the AWT font to use for the specific character. This might not always be the same, in case a we are trying to draw an unusual character (probably CJK) which isn't contained in the standard terminal font.

Specified by:

isTextAntiAliased in class GraphicalTerminalImplementation

Returns:

true if anti-aliasing is enabled, false otherwise

repaint

protected void repaint()

Description copied from class: GraphicalTerminalImplementation

Called by the GraphicalTerminalImplementation when it would like the OS to schedule a repaint of the window

Specified by:

repaint in class GraphicalTerminalImplementation

readInput

public KeyStroke readInput()

Description copied from interface: InputProvider

Returns the next Key off the input queue or blocks until one is available. NOTE: In previous versions of Lanterna, this method was not blocking. From lanterna 3, it is blocking and you can call pollInput() for the non-blocking version.

Specified by:

readInput in interface InputProvider

Specified by:

readInput in interface IOSafeTerminal

Overrides:

readInput in class GraphicalTerminalImplementation

Returns:

Key object which represents a keystroke coming in through the input stream
