Class PercentLayout

java.lang.Object
  com.l2fprod.common.swing.PercentLayout

All Implemented Interfaces:

java.awt.LayoutManager, java.awt.LayoutManager2

Direct Known Subclasses:

BasicOutlookBarUI.TabLayout

public class PercentLayout
extends java.lang.Object
implements java.awt.LayoutManager2

PercentLayout.
Constraint based layout which allow the space to be splitted using percentages. The following are allowed when adding components to container:

• container.add(component);
  in this case, the component will be sized to its preferred size
• container.add(component, "100");
  in this case, the component will have a width (or height) of 100
• container.add(component, "25%");
  in this case, the component will have a width (or height) of 25 % of the container width (or height)
  
• container.add(component, "*");
  in this case, the component will take the remaining space. if several components use the "*" constraint the space will be divided among the components.

Field Summary

static int	HORIZONTAL Useful constant to layout the components horizontally (from left to right).
static int	VERTICAL Useful constant to layout the components vertically (from top to bottom).

Constructor Summary

PercentLayout()
Creates a new HORIZONTAL PercentLayout with a gap of 0.

PercentLayout(int orientation, int gap)

Method Summary

void	addLayoutComponent(java.awt.Component component, java.lang.Object constraints)
void	addLayoutComponent(java.lang.String name, java.awt.Component comp) Adds the specified component with the specified name to the layout.
com.l2fprod.common.swing.PercentLayout.Constraint	getConstraint(java.awt.Component component)

getOrientation

public int getOrientation()

getConstraint

public com.l2fprod.common.swing.PercentLayout.Constraint getConstraint(java.awt.Component component)

setConstraint

public void setConstraint(java.awt.Component component,
                          java.lang.Object constraints)

addLayoutComponent

public void addLayoutComponent(java.awt.Component component,
                               java.lang.Object constraints)

Specified by:

addLayoutComponent in interface java.awt.LayoutManager2

getLayoutAlignmentX

public float getLayoutAlignmentX(java.awt.Container target)

Returns the alignment along the x axis. This specifies how the component would like to be aligned relative to other components. The value should be a number between 0 and 1 where 0 represents alignment along the origin, 1 is aligned the furthest away from the origin, 0.5 is centered, etc.

Specified by:

getLayoutAlignmentX in interface java.awt.LayoutManager2

getLayoutAlignmentY

public float getLayoutAlignmentY(java.awt.Container target)

Returns the alignment along the y axis. This specifies how the component would like to be aligned relative to other components. The value should be a number between 0 and 1 where 0 represents alignment along the origin, 1 is aligned the furthest away from the origin, 0.5 is centered, etc.

Specified by:

getLayoutAlignmentY in interface java.awt.LayoutManager2

invalidateLayout

public void invalidateLayout(java.awt.Container target)

Invalidates the layout, indicating that if the layout manager has cached information it should be discarded.

Specified by:

invalidateLayout in interface java.awt.LayoutManager2

addLayoutComponent

public void addLayoutComponent(java.lang.String name,
                               java.awt.Component comp)

Adds the specified component with the specified name to the layout.

Specified by:

addLayoutComponent in interface java.awt.LayoutManager

Parameters:
