Grid Helpers Add-on is written by Flowing Code S.A.
The class GridHelper
provides several static methods that receive a Grid
or Column
as the first parameter:
grid.setSelectionMode(SelectionMode.MULTI);
grid.addThemeName(GridHelper.DENSE_THEME);
GridHelper.setSelectOnClick(grid, true);
GridHelper.setArrowSelectionEnabled(grid, true);
GridHelper.setSelectionColumnHidden(grid, true);
Column<Person> firstNameColumn = grid.addColumn(Person::getFirstName).setHeader("First name");
GridHelper.setHidingToggleCaption(firstNameColumn, "First name");
If you use Project Lombok, you can benefit from the extension method feature:
@ExtensionMethod(GridHelper.class)
public class LombokDemo extends Div {
public LombokDemo() {
Grid<Person> grid = new Grid<>();
grid.setSelectionMode(SelectionMode.MULTI);
grid.setSelectionColumnHidden(true);
grid.setSelectOnClick(true);
grid.setSelectionFilter(Person::isActive);
grid.addColumn(Person::getFirstName)
.setHeader("First name")
.setHidingToggleCaption("First name");
add(grid);
}
}
By default, Vaadin Flow only includes com/vaadin/flow/component
to be always scanned for UI components and views. For this reason, the add-on might need to be whitelisted in order to display correctly.
To do so, just add com.flowingcode
to the vaadin.whitelisted-packages
property in src/main/resources/application.properties
, like:
vaadin.whitelisted-packages = com.vaadin,org.vaadin,dev.hilla,com.flowingcode
More information on Spring whitelisted configuration here.
