Refresh Button in java
- by lakshmi
I need to make a simple refresh button for a gui java program I have the button made but its not working properly. I just am not sure what the code needs to be to make the button work. Any help would be really appreciated.I figured the code below
`
public class CompanySample extends Panel {
DBServiceAsync dbService = GWT.create(DBService.class);

sm.addListener(new RowSelectionListenerAdapter() {
public void onRowSelect(RowSelectionModel sm, int rowIndex,
Record record) {
formPanel.getForm().loadRecord(record);
}
});
gridPanel.setSelectionModel(sm);
gridPanel.doOnRender(new Function() {
public void execute() {
sm.selectFirstRow();
}
}, 10);
