Differences between SWT and DWT

Package and Module renames

packages rename: "org.eclipse.swt" to "dwt"
packages rename: "org.eclipse" to "dwtx" for all non-swt packages (jface,...)
Renamed every "SWT" to "DWT".

Examples:

"org.eclipse.swt.widgets.Button" becomes "dwt.widgets.Button",
"org.eclipse.swt.SWT" becomes "dwt.DWT".

Widget getData, setData

All SWT widgets have the possibility to set and get a data values that are passed as Objects. DWT extends those for Strings explicitly and adds:

public void setDataStr( String value );
public void setDataStr( String key, String value );
public String getDataStr();
public String getDataStr( String value );

Strings passed as an argument can be null in DWT

Many of the SWT methods do accept the empty string, but not the null string. In D there is no such difference. This is the same for arrays of other type. This is, why many methods in DWT are made to accept the null argument. This is made by simply deactivating this check. If the error was documented in the associated JavaDoc, it is removed in DWT.

This looks typically like this:

// DWT extension: allow null for zero length string
//if (string is null) DWT.error (DWT.ERROR_NULL_ARGUMENT);

Things added or changed in DWT:

MessageBox can have null as parent to allow a MessageBox without a Shell
There are five new static methods in MessageBox:
- showMessageBox
- showInfo
- showInformation (an alias to showInfo)
- showWarning
- showError
dwt.dwthelper.Runnable has a dgRunnable template function to use delegates and to buffer arguments.
dwt.widgets.Listener has a dgListener template function to use delegates and to buffer arguments.
