Method Detail

createFontUIResource

public static FontUIResource createFontUIResource(String name,
                                                  int style,
                                                  int size)

createFont

public static Font createFont(String name,
                              int style,
                              int size)

Creates font. If there is no permission to access font file, it will try to create the font directly from font file that is bundled as part of jar.

Parameters:

name - the font name.

style - the font style.

size - the font size.

Returns:

the font.

getProperty

public static String getProperty(String key,
                                 String defaultValue)

Gets the system property.

Parameters:

key - the property key

defaultValue - the default value for the property.

Returns:

the system property.

isAWTEventListenerDisabled

public static boolean isAWTEventListenerDisabled()

Checks if AWTEventListener is disabled. This flag can be set by user. If false, JIDE code will read the value and not use AWTEventListener. The reason we need this flag is because AWTEventListener needs a special security permission. If applet, it will throw security if the user policy doesn't have the correct permission.

Returns:

true if AWTEventListener is disabled.

setAWTEventListenerDisabled

public static void setAWTEventListenerDisabled(boolean AWTEventListenerDisabled)

Enables or disables the usage of AWTEventListener. If you want to change it, you should change the value at the beginning of your main method.

Parameters:

AWTEventListenerDisabled - true or false.

isTranslucentWindowFeatureDisabled

public static boolean isTranslucentWindowFeatureDisabled()

Checks if the translucent window feature is disabled. It is disabled by default if the JDK version is less than JDK6 u10 or theOS is not Windows.

Returns:

true or false.

setTranslucentWindowFeatureDisabled

public static void setTranslucentWindowFeatureDisabled(boolean translucentWindowFeatureDisabled)

Disables or enables the usage of the translucent window feature available since JDK6u10. This feature is used in Alert for fading animation.

Parameters:

translucentWindowFeatureDisabled - true or false.
