Constructor Detail

TextDisplay

public TextDisplay(int x,
                   int y,
                   Color textColor)

Constructs a TextDisplay to display text at the specified coordinates in the specified color. If the text is to be drawing inside a box (see setBoxVisible(), x and y mark the top left corner of this box. If the text is not drawn inside a box then x and y mark the position of the baseline of left-most character in the first string to be drawn.

Parameters:

x - the x coordinate

y - the y coordinate

textColor - the color to draw the text and box

                   int x,
                   int y,
                   Color textColor)

Constructs a TextDisplay to display text at the specified coordinates in the specified color. If the TextDisplay is the first Display added to a DisplaySurface then width and height must be specified. If the text is to be drawing inside a box (see setBoxVisible(), x and y mark the top left corner of this box. If the text is not drawn inside a box then x and y mark the position of the baseline of left-most character in the first string to be drawn.

Parameters:

width - the width of the display

height - the height of the display

x - the x coordinate

y - the y coordinate

textColor - the color to draw the text and box
