                               ValueCallback callback)

Show a modal dialog with a text entry box, asking the user to enter a value.

As with other convenience methods that show Dialogs, such as #warn(String, String, BooleanCallback) , the dialog is shown and the function immediately returns. When the user responds, the provided callback is called.

If the user clicks OK, the value typed in is passed to the callback (including the empty string ("") if nothing was entered. If the user clicks cancel, the value passed to the callback is null.

A default value for the text field can be passed via properties.defaultValue

Keyboard focus is automatically placed in the text entry field, and hitting the enter key is the equivalent of pressing OK.

Parameters:

message - message to display

callback - Callback to fire when the user clicks a button to dismiss the dialog. This has the single parameter 'value', indicating the user entry, or null if cancel was pressed or the window closed

dismissCurrentDialog

public static void dismissCurrentDialog()

If a dialog triggered via say(String), ask(String, BooleanCallback), warn(String), confirm(String, BooleanCallback) or askforValue(String, ValueCallback) is currently visible, it will be dismissed. The callback passed to the relevant method will never fire.

Note this is a rarely used API with very few valid use cases. As an example, perhaps some kind of periodic (non-user triggered) event would cause an entire area of the UI to be removed (such as a tab) and the system wants to ensure that no modal dialogs are currently showing from that part of the UI. In this case, while dismissCurrentDialog could be used to ensure the part of the UI being removed didn't leave behind a modal dialog.

To clear a modal prompt shown by showPrompt(String), use clearPrompt() instead.

showPrompt

public static void showPrompt(java.lang.String message)

Show a modal prompt to the user. This method will display the message using the Dialog.Prompt singleton object.

Note: if this prompt is to be shown to the user during some slow logic, we advise calling this method, then using DeferredCommand to kick off the slow logic in a separate thread. This ensures that the prompt is showing before the lengthy execution begins.

Parameters:

message - message to display

Returns the current stack trace, from a JavaScript perspective. This should provide meaningful JS stack frames for Java code in Super Development Mode, and in Production Mode, if GWT compilation has been configured with options such as "‑optimize 0" and/or "‑style PRETTY" to disable obfuscation. Frames corresponding to the native SmartClient Framework will be obfuscated unless the GWT project is configured for debugging.

In Classic DevMode, this API will provide very limited information - stack frames corresponding to Java code will likely be displayed as anonymous functions, and many or most such frames will be missing. For DevMode, it's preferable to use GWT-supported Java APIs to capture the stack, such as for example:

     Throwable t = new Throwable();

     String stack = "";
     for (StackTraceElement element : t.getStackTrace()) {
         stack += element + "\n";
     }

     SC.logDebug("Current location: " + stack);
 

Grabbing Java StackTraceElements in Super Development Mode or Production Mode will work, but won't provide any added benefit as in DevMode.

Debugging

setEnableJSDebugger

public static void setEnableJSDebugger(boolean useDebugger)

Setting this to true will result in the IE / Firebug / Safari debugger being invoked when a JavaScript error is encountered. This is done by the execution of the commend "debugger;" when the error occurs. Setting this to true is useful for debugging any javascript errors.

Parameters:

useDebugger - default is false

logEchoAll

public static void logEchoAll(Canvas canvas,
                              java.lang.String message)

Parameters:

canvas - canvas to echo

message - the message to log

setScreenReaderMode

public static void setScreenReaderMode(boolean newState)

Enables full screen reader mode. Must be called before any components are created. See Accessibility.

Parameters:

new - state for screen reader mode (true for enabled, false for disabled)

isMethodSupported

public static boolean isMethodSupported(java.lang.String className,
                                        java.lang.String methodName)

Returns true if the method is supported by the class, meaning that it is not null and was not replaced by markUnsupportedMethods(String, String, String[]).

Parameters:

className - className to check

methodName - methodName to check

Returns:

boolean true if the method is not null and is not an unsupported method; false otherwise.

markUnsupportedMethods

public static void markUnsupportedMethods(java.lang.String className,
                                          java.lang.String messageTemplate,
                                          java.lang.String[] methodNames)

Replaces each of the methods named in methodNames with a new implementation that simply logs a warning the first time the method is called, and nothing else. This can be used to mark methods of derived classes which do not support certain parent class methods as unsupported.

The messageTemplate parameter is a template for the warning message logged when the unsupported method is first called. The following variables in the template are substituted as follows:

Variable	Substitution
$class	The +link{getClassName(),class name}.
$method	The name of the method.

If you want the literal string of a substitution variable to appear in the warning message, you can escape it by prefixing with a dollar sign. For example, to include "$class" in the warning message, use "$$class" in the template.

Parameters:

className - className containing methods to mark

messageTemplate - template for the warning message logged when first called. If null, the default template string "$class does not support the $method() method." is used.

methodNames - the method names to mark as unsupported.

traceLogMessage

public static void traceLogMessage(java.lang.String messagePattern)

Causes a stack trace to be logged any time a message containing the provided pattern is logged. This can help figure out the origin of warnings or other mysterious logs in a large complex application.

The passed messagePattern is interpreted as a JavaScript regular expression.

Parameters:

messagePattern -
