Constructor Detail

MeasureWidget

public MeasureWidget()

Construct a new measure widget

Method Detail

setFood

public void setFood(Food f)

Set the measure to display weights for a particular food.

setMeasure

public void setMeasure(Measure w,
                       double mult)

Set the weight to display

Parameters:

w - the type of measure

mult - the multiplier for that measure

updateMeasure

public void updateMeasure()

Update the widget after a weight change has occurred. Called when weight menu is changed or edited

getMultiplier

public double getMultiplier()

Get the multiplier for the current weight and mult settings.

Returns:

a multiple of the standard nutrient value (x per 100g)

getGrams

public double getGrams()

Get the number of grams in this measure

Returns:

the number of grams in this state

getSelectedMeasure

public Measure getSelectedMeasure()

focus

public void focus()

Focus the component, selecting the text field and giving it keyboard focus.

addChangeListener

public void addChangeListener(javax.swing.event.ChangeListener l)

addRemoveListener

public void addRemoveListener(javax.swing.event.ChangeListener l)

fireChangeEvent

public void fireChangeEvent()

itemStateChanged

public void itemStateChanged(java.awt.event.ItemEvent e)

Called if the weight menu state is changed

Specified by:

itemStateChanged in interface java.awt.event.ItemListener

actionPerformed

public void actionPerformed(java.awt.event.ActionEvent arg0)

Called when the text field is set

Specified by:

actionPerformed in interface java.awt.event.ActionListener

keyTyped

public void keyTyped(java.awt.event.KeyEvent arg0)

Specified by:

keyTyped in interface java.awt.event.KeyListener

keyPressed

public void keyPressed(java.awt.event.KeyEvent arg0)

Specified by:

keyPressed in interface java.awt.event.KeyListener

keyReleased

public void keyReleased(java.awt.event.KeyEvent arg0)

Called when the text field is edited

Specified by:

keyReleased in interface java.awt.event.KeyListener

isLinked

public boolean isLinked()

If linked, changing a weight will update the multiplier to keep the grams constant. Otherwise, the multiplier is left unchanged.

Returns:

true if the multiplier is linked to the weight

setLinked

public void setLinked(boolean linked)

If linked, changing a weight will update the multiplier to keep the grams constant. Otherwise, the multiplier is left unchanged.
