Hi everyone,
When I make a simple CellTable, the responsiveness of the table in the
browser to mouse events (mouseOver, mouseOut) is nowhere nearly as
fast as the table in the Showcase (http://gwt.google.com/samples/
Showcase/Showcase.html#!CwCellTable). Any ideas why this might be?
My code is below. Best,
~Owen
// Data object class.
package tabletest.client;
import java.util.ArrayList;
public class InterestingThing {
public ArrayList<String> values = new ArrayList<String>();
public InterestingThing(int n) {
for (int i=0; i<n; i++) {
values.add("Value " + i);
}
}
}
// Custom CellTable class.
package tabletest.client;
import java.util.ArrayList;
import com.google.gwt.user.cellview.client.CellTable;
import com.google.gwt.user.cellview.client.TextColumn;
public class MyCellTable extends CellTable<InterestingThing> {
public MyCellTable() {
super();
int NUM_COLUMNS = 4;
int NUM_ROWS = 25;
// Create table.
for (int i=0; i<NUM_COLUMNS; i++) {
addTextColumn(i);
}
// Create data.
ArrayList<InterestingThing> data = new
ArrayList<InterestingThing>();
for (int i=0; i<NUM_ROWS; i++) {
data.add(new InterestingThing(NUM_COLUMNS));
}
// Put data into table.
setRowData(0, data);
}
private void addTextColumn(final int i) {
TextColumn<InterestingThing> newColumn = new
TextColumn<InterestingThing>() {
public String getValue(InterestingThing m) {
return m.values.get(i);
}
};
addColumn(newColumn, "Field " + i);
}
}
// Entrypoint.
package tabletest.client;
import com.google.gwt.core.client.EntryPoint;
import com.google.gwt.user.client.ui.RootPanel;
public class TableTest implements EntryPoint {
public void onModuleLoad() {
MyCellTable table = new MyCellTable();
RootPanel.get().add(table);
}
}
