java.lang.Objectorg.bounce.FormLayout
public class FormLayout
A Layout manager that can be used to layout 2 columns of components.
The alignment and fill type of the columns can be set by using the
FormConstraint class.
A couple of predefined FormConstraint objects have been defined:
Field Summary | |
---|---|
static FormConstraints |
FULL
A constraint that allows the component to use the total width of the form. |
static FormConstraints |
FULL_FILL
A constraint that allows the component to use the total width of the form and resizes the component to fill the whole width. |
static FormConstraints |
LEFT
A constraint that adds the component to the left side of the form. |
static FormConstraints |
RIGHT
A constraint that adds the component to the right side of the form. |
static FormConstraints |
RIGHT_FILL
A constraint that adds the component to the right side of the form and resizes the component to fill the whole available width. |
Constructor Summary | |
---|---|
FormLayout()
Constructs a default FormLayout without any horizontal or vertical gaps. |
|
FormLayout(int hGap,
int vGap)
Constructs a FormLayout with the specified horizontal and vertical gap. |
Method Summary | |
---|---|
void |
addLayoutComponent(Component component,
Object constraints)
Adds the specified component to the layout, using the specified constraint object. |
void |
addLayoutComponent(String name,
Component comp)
Not used, components cannot be added without a constraint. |
int |
getHgap()
Returns the horizontal gap between the left column and the right column. |
float |
getLayoutAlignmentX(Container target)
Returns the alignment along the x axis. |
float |
getLayoutAlignmentY(Container target)
Returns the alignment along the y axis. |
int |
getVgap()
Returns the vertical gap between the rows. |
void |
invalidateLayout(Container target)
Invalidates the layout, indicating that if the layout manager has cached information it should be discarded. |
void |
layoutContainer(Container parent)
Lays out the components on the specified container. |
Dimension |
maximumLayoutSize(Container target)
Returns the maximum size of this component. |
Dimension |
minimumLayoutSize(Container parent)
Calculates the minimum size dimensions for the specified panel given the components in the specified parent container. |
Dimension |
preferredLayoutSize(Container parent)
Calculates the preferred size dimensions for the specified container given the components in the specified parent container. |
void |
removeLayoutComponent(Component component)
Removes the specified component and constraints from the layout. |
void |
setConstraints(Component component,
Object constraint)
Adds the specified component to the layout, using the specified constraint object. |
void |
setHgap(int hGap)
Sets the horizontal gap between the left column and the right column. |
void |
setVgap(int vGap)
Returns the vertical gap between the rows. |
