Got it!
1) Create new TextField and repalce by one below
2)_ I have only
i ) overwriten ----- public Metrics getPreferredSize(int preferredWidth)
ii changed -------- protected String getDisplayedText()
iii added utili method --------- private int getMaxSizeWidth() {
3) to specify min size for text
i) on the xmal <textfield style="min-size:200 0; ......." />
ii) or on the css textfield { min-size: 160 0; }
4) To specify maxsize
i) use ither only the min size above as min and max .
ii )or use only the xml maxsize an as min and max. <textfield style="..." maxsize="10"/>
iii) or use both to specify min and max <textfield style="min-size:80 0; ......." maxsize="20"/>
Please note tha above specifies min as 10 (8*10) chars and max as 20 chars.
Enjoy,
