setFontForZoom

Field Detail

currentFontIndex

protected int currentFontIndex

Constructor Detail

AbstractFontManager

public AbstractFontManager()

Call this in subclasses with the super() constructor.

Method Detail

makeFonts

protected abstract void makeFonts()

Make widget-specific fonts.

getFontName

public String getFontName()

Get the font family name used in this font manager.

Returns:

the font name

setFontName

public void setFontName(String fontName)

Set the font name ('Arial', 'Times New Roman') and so on.

Specified by:

setFontName in interface IFontManager

Parameters:

fontName - name of the font to use

setFontStyle

public void setFontStyle(IFontManager.FontStyle fontStyle)

Set the font style.

Specified by:

setFontStyle in interface IFontManager

Parameters:

fontStyle - an IFontManager.FontStyle type

getFontStyle

public IFontManager.FontStyle getFontStyle()

Get the font style, defined in the IFontManager interface.

Returns:

the font style

registerFontSizeMapping

public void registerFontSizeMapping(double zoom,
                                    int size)

For a particular zoom level, register a font point-size so that this size of font will be used when the zoom is at this level.

Parameters:

zoom - the zoom level

size - the font size

getFontSizeForZoom

protected Integer getFontSizeForZoom(double zoom)

For a particular zoom, get the appropriate font size.

Parameters:

zoom - the zoom level

Returns:

an integer font size

getNumberOfFontSizes

public int getNumberOfFontSizes()

Get the number of font sizes used.

Returns:

the size of the zoom to font map

resetVirtualCounts

public void resetVirtualCounts()

Reset the virtual counts.

toMiddle

public void toMiddle()

Set the font size pointer to the middle of the range.

increaseFontSize

public void increaseFontSize()

Move the font size pointer up. If this would move the pointer past the maximum font size, track this increase with a virtual size.

decreaseFontSize

public void decreaseFontSize()

Move the font size pointer down. If this would move the pointer past the minimum font size, track this increase with a virtual size.

inRange

public boolean inRange()

Check that the font pointer is in the range (0, numberOfFonts - 1).

Returns:

true if the current font index is between 0 and |fonts| - 1

atLowerBoundary

public boolean atLowerBoundary()

Test the virtual font pointer to see if it is at the lower boundary of the font size range (0).

Returns:

true if the lower virtual count is zero

atUpperBoundary

public boolean atUpperBoundary()

Test the virtual font pointer to see if it is at the upper boundary of the font size range (|fonts| - 1).

Returns:

true if the upper virtual count is |fonts| - 1

inLower

public boolean inLower()

Test to see if the lower virtual pointer is in use.

Returns:

true if the lower virtual count is less than zero

inUpper

public boolean inUpper()

Test to see if the upper virtual pointer is in use.

Returns:

true if the upper virtual count is greater than |fonts| - 1

atMax

public boolean atMax()

Check if the font pointer is as the maximum value.

Returns:

true if the current font index is equal to |fonts| - 1

atMin

public boolean atMin()

Check if the font pointer is as the minimum value.

Returns:

true if the current font index is equal to zero
