eSWT, or embedded Standard Widget Toolkit, is a component of the embedded Rich Client Platform (eRCP), and a subset of desktop SWT API. For deployment adaptability the API is divided into two packages: Core eSWT, containing the base function and simple widgets and Expanded eSWT, containing more complex widgets (Table, Tree, WebBrowser) and additional layouts and dialogs.
Gorkem Ercan, an Eclipse committer for Eclipse Webtools (WTP) and the eRCP projects, opines that eSWT should be available for midlets. He gives the reason for the same:
eSWT is a great UI toolkit with features beyond mobile UI toolkits, that are compatible to desktop UI toolkits
It requires only CLDC
CLDC+MIDP is the most common java ME configuration
An advanced UI toolkit is(or was) a big missing piece on CLDC+MIDP if not all java ME space
Availability of eSWT on midlets makes it easier for the applications to transition to eRCP
He adds that though there is no bug report for this, and the post was mainly to gauge the general opinion, which by the looks for it, seems to be a resounding yes!
