Constructor Detail

AdjustableLayout

public AdjustableLayout(int orientation)

Method Detail

updateLayout

public void updateLayout(java.awt.Rectangle parent,

                         LayoutContext child)

Overrides:

updateLayout in class Layout

setValues

public void setValues(int value,

                      int visible,

                      int min,

                      int max)

scroll

public void scroll(int pixels)

Moves the value by the requested number of pixels. Pixels that fall out of range are ignored. This method asumes that the ratio of pixels to increments has not changed since the lst call to updateLayout(..).

Parameters:

pixels - the number of pixels to move from the current value

incrementBlock

public void incrementBlock(int i)

incrementUnit

public void incrementUnit(int i)

getOrientation

public int getOrientation()

Gets the orientation of the adjustable object.

Specified by:

getOrientation in interface java.awt.Adjustable

setMinimum

public void setMinimum(int min)

Sets the minimum value of the adjustable object.

Specified by:

setMinimum in interface java.awt.Adjustable

Parameters:

min - the minimum value

getMinimum

public int getMinimum()

Gets the minimum value of the adjustable object.

Specified by:

getMinimum in interface java.awt.Adjustable

setMaximum

public void setMaximum(int max)

Sets the maximum value of the adjustable object.

Specified by:

setMaximum in interface java.awt.Adjustable

Parameters:

max - the maximum value

getMaximum

public int getMaximum()

Gets the maximum value of the adjustable object.

Specified by:

getMaximum in interface java.awt.Adjustable

setUnitIncrement

public void setUnitIncrement(int u)

Sets the unit value increment for the adjustable object.

Specified by:

setUnitIncrement in interface java.awt.Adjustable

Parameters:

u - the unit increment

getUnitIncrement

public int getUnitIncrement()

Gets the unit value increment for the adjustable object.

Specified by:

getUnitIncrement in interface java.awt.Adjustable

setBlockIncrement

public void setBlockIncrement(int b)

Sets the block value increment for the adjustable object. A block increment less than 1 will reset the block to the visible amount.

Specified by:

setBlockIncrement in interface java.awt.Adjustable

Parameters:

b - the block increment

getBlockIncrement

public int getBlockIncrement()

Gets the block value increment for the adjustable object.

Specified by:

getBlockIncrement in interface java.awt.Adjustable

Specified by:

setValue in interface java.awt.Adjustable

Parameters:

v - the current value

getValue

public int getValue()

Gets the current value of the adjustable object.

Specified by:

getValue in interface java.awt.Adjustable
