Populate huge data dynamically in SWT widget table
.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ height:90px;width:728px;box-sizing:border-box;
}
I want to populate huge data in SWT Table. After searching the internet, I found the below code. But this code populates the hardcode data.
public static void main( String args ) {
Display display = new Display();
Shell shell = new Shell( display );
shell.setLayout( new FillLayout() );
final Table table = new Table( shell, SWT.VIRTUAL );
table.setItemCount( 10000 );
table.addListener( SWT.SetData, new Listener() {
public void handleEvent( Event event ) {
TableItem item = (TableItem)event.item;
item.setText("Item" + table.indexOf( item ) ); // should be replaced
// by below for loop
}
} );
shell.setSize( 300, 500 );
shell.open();
while( !shell.isDisposed() ) {
if( !display.readAndDispatch() ) {
display.sleep();
}
}
display.dispose();
}
I want to populate something like below inside the table.addListener handle event. Please help me in this. Thanks in advance!
for (int i = 0; i < informationList.size(); i++) {
TableItem item = new TableItem(informationTable, SWT.CENTER);
item.setText(1, informationList.get(i).getName());
item.setText(2, "");
item.setText(3, "");
item.setText(4, ""+informationList.get(i).getId());
}

A virtual table asks via the listener for the contents of the currently visible rows. That's what the virtual table is all about: "Don't call us, we'll call you!"
table.addListener(SWT.SetData, new Listener() {
public void handleEvent( Event event ) {
TableItem item = (TableItem)event.item;
int index = table.indexOf(item);
item.setText(1, informationList.get(index).getName());
item.setText(2, "");
item.setText(3, "");
item.setText(4, "" + informationList.get(index).getId());
}
});
See also Javadoc of the Table widget which also contains an example (highlighting by me):
Style
VIRTUALis used to create a Table whose TableItems are to be
populated by the client on an on-demand basis instead of up-front.
This can provide significant performance improvements for tables that
are very large or for which TableItem population is expensive (for
example, retrieving values from an external source).
