constrain

public static final void constrain(java.awt.Container container,
                                   java.awt.Component component,
                                   int grid_x,
                                   int grid_y,
                                   int grid_width,
                                   int grid_height,
                                   int fill,
                                   int anchor,
                                   double weight_x,
                                   double weight_y,
                                   int top,
                                   int left,
                                   int bottom,
                                   int right)

adds component with constraints to the container

Parameters:

container - the container to which the component will be added

component - the component/widget which will be added to the container

grid_x - the x grid position of the component

grid_y - the y grid position of the component

grid_width - the width of the component in grid cells

grid_height - the height of the component in grid cells

fill - which dimensions of the component will grow

anchor - specifies how the component will be displayed if smaller than cells

weight_x - specifies how extra space in x will be distributed

weight_y - specifies how extra space in y will be distributed

top - the top margin

left - the left margin

bottom - the bottom margin

right - the right margin

add1component

public static final int add1component(java.awt.Container cont,
                                      java.awt.Component c1,
                                      int yrow)

adds one component stretches over 2 xgrids and returns the next row number

Parameters:

cont - the container to add the component to

c1 - the component to add

yrow - the ygrid row in which to add the component; xgrid is 0

add2components

public static final int add2components(java.awt.Container cont,

adds two components side-by-side in the row and returns the next row number

Parameters:

cont - the container to add the components to

c1 - left most component to add; at xgrid of 0

c2 - right most component to add; at xgrid of 1

yrow - the ygrid row in which to add the component

addcomponentinrow
