Support
#1

Hi,
is it possibile to add Vaadin TreeGrid to a View ?
Using Jmix UI ?
I can add it from code on View Controller

‘’’
import com.vaadin.flow.component.treegrid.TreeGrid;
import com.vaadin.flow.component.button.Button;

    public void buildDemo() {
    final Button btn = new Button("Save");
    btn.addThemeVariants(ButtonVariant.LUMO_ERROR);
    final TreeGrid treeGrid = new TreeGrid<GeoTreeNodeEntity>();
    mainFlexLayout.add(btn);
    mainFlexLayout.add(treeGrid);
   }

‘’’

Is there a way to add any Vaadin standard compoent to a View
using Jmix UI?
Might it be useful to have all the standard Vaadin components in the Jmix UI ?

Hi, Stefano!

There is TreeDataGreed component in Jmix.
https://docs.jmix.io/jmix/flow-ui/vc/components/treeDataGrid.html

Does it solve your problem?

Thanks.

I solved "partially using TreeDataGreed " and post a solution here
#How to select row on click on row in tree datagrid - #3 by scarfagna72

but i dont like it because I’ve to create a
TreeDataGreed need to create a JmixEntiy but id dont need to save it .

The best solution is to use a native Vaadin tree and Pojo or Dto.
I can do it from ViewController and code as I shown (look at the link) .

But could be nice to have a Jmix UI tool showing native Vaadin component to add to the View.

Hi, Stefano!

You can use Jmix DTO with TreeDataGrid
https://docs.jmix.io/jmix/data-model/entities.html#dto

Is there any reasons not to use it?

Thanks, Pavel.
