Method Detail

getDefaultFontIncrease

public static int getDefaultFontIncrease()

Preferred font size increase if none is specified.

Returns:

current value of defaultFontIncrease

getDefaultSizeIncrease

public static int getDefaultSizeIncrease()

Preferred control size increase if none is specified.

Returns:

current value of defaultSizeIncrease

getDefaultSkin

public static java.lang.String getDefaultSkin()

Preferred default skin if none is specified.

Returns:

current value of defaultSkin

getIsDesktop

public static boolean getIsDesktop()

Is the application running in a desktop browser? This is true if isTablet and isHandset are both false.

Returns:

current value of isDesktop

getIsHandset

public static boolean getIsHandset()

Is the application running on a handset-sized device, with a typical screen width of around 3-4 inches?

This typically implies that the application will be working with only 300-400 pixels.

Returns:

current value of isHandset

getIsTablet

public static boolean getIsTablet()

Is the application running on a tablet device (e.g. iPad, Nexus 7)?

Smart GWT can correctly determine whether the device is a tablet in most cases. On any uncommon device for which this variable is incorrect, you can define the isc_isTablet global with the correct value, and Smart GWT will use isc_isTablet for Browser.isTablet instead of its own detection logic. Alternatively, you can use setIsTablet() to change this global variable before any components are created.

The value of this variable is only meaningful on touch devices.

Returns:

current value of isTablet

getIsTouch

public static boolean getIsTouch()

Is the application running on a touch device (e.g. iPhone, iPad, Android device, etc.)?

Smart GWT's auto-detected value for isTouch can be overridden via setIsTouch().

Returns:

current value of isTouch

getSupportsFlatSkins

public static boolean getSupportsFlatSkins()

Whether browser is capable of rendering flat skins (e.g. Tahoe).

Returns:

current value of supportsFlatSkins

setIsDesktop

public static void setIsDesktop(boolean isDesktop)

Setter for isDesktop to allow this global variable to be changed at runtime. This advanced method is provided to override Smart GWT's detection of devices, since the framework can only detect devices that existed at the time the platform was released. Any changes to isDesktop, isHandset, or isTablet must be made before any component is created; it is an application error to attempt to change isDesktop, isHandset, or isTablet after components have been created.

Note that setting Browser.isDesktop might affect the values of isHandset and isTablet.

Parameters:

isDesktop - new setting for Browser.isDesktop.

setIsHandset

public static void setIsHandset(boolean isHandset)

Setter for isHandset to allow this global variable to be changed at runtime. This advanced method is provided to override Smart GWT's detection of devices, since the framework can only detect devices that existed at the time the platform was released. Any changes to isDesktop, isHandset, or isTablet must be made before any component is created; it is an application error to attempt to change isDesktop, isHandset, or isTablet after components have been created.

Note that setting Browser.isHandset might affect the values of isDesktop and isTablet.

Parameters:

isHandset - new setting for Browser.isHandset.

setIsTablet

public static void setIsTablet(boolean isTablet)

Setter for isTablet to allow this global variable to be changed at runtime. This advanced method is provided to override Smart GWT's detection of devices, since the framework can only detect devices that existed at the time the platform was released. Any changes to isDesktop, isHandset, or isTablet must be made before any component is created; it is an application error to attempt to change isDesktop, isHandset, or isTablet after components have been created.

Note that setting Browser.isTablet might affect the values of isDesktop and isHandset.

Parameters:

isTablet - new setting for Browser.isTablet.

setIsTouch

public static void setIsTouch(boolean isTouch)

Setter for isTouch to allow this global variable to be changed at runtime. This advanced method is provided to override Smart GWT's auto-detection logic, since the framework can only detect touch devices that existed at the time the platform was released. Any change to isTouch must be made before any component is created; it is an application error to attempt to change isTouch after components have been created.

Note that setting Browser.isTouch might affect the values of isDesktop, isTablet, and/or isHandset.

Parameters:

isTouch - new setting for Browser.isTablet.
