Method Detail

paint

public void paint(java.awt.Graphics g,
                  int x,
                  int y,
                  int w,
                  int h,
                  Drawable d)

Paints the render using a given width and height. The location where the view has to be painted is determined with x and y coordinates. This abstract method has to be implmented to define a "face" for the view.

Overrides:

paint in class LwTextRender

Parameters:

g - the specified context to be used for painting.

x - the x coordinate.

y - the y coordinate.

w - the width of the view.

h - the height of the view.

d - the owner component.

calcPreferredSize

protected java.awt.Dimension calcPreferredSize()

Calculates and returns the render preferred size. The method doesn't use the view insets to compute the preferred size.

Overrides:

calcPreferredSize in class LwTextRender

Returns:

a "pure" preferred size of the view.

paintPage

protected void paintPage(java.awt.Graphics g,
                         int x,
                         int y,
                         int w,
                         int h,
                         Drawable d)

Paints the border for the view. The border type depends on a page tab orientation that can have following values: Alignment.TOP, Alignment.BOTTOM, Alignment.LEFT, Alignment.RIGHT.

Parameters:

g - the specified context to be used for painting.

x - the x coordinate.

y - the y coordinate.

w - the width of the view.

h - the height of the view.

d - the owner component.
