ContextClick handler for group summaries

[admin@seacomp.cz]

Hello Iso,

we have encountered a difficulty showing a context menu for group summaries.
In short, when either rowContextClickHandler or cellContextClickHandler are added to a listGrid they do not fire when a group summary row is 'context'-clicked whereas clicking a regular record (row/cell) fires respective event.

TestCase can be made easily by taking https://www.smartclient.com/smartgwt...tured_category and attaching either contextClickHandler to the grid.

 listGrid.addRowContextClickHandler(event -> {          
   listGrid.getField(event.getColNum()).setTitle("Clickyclick");          
   listGrid.refreshFields();
 });  

listGrid.addCellContextClickHandler(event -> {          
   listGrid.getField(event.getColNum()).setTitle("Clickyclick2");          
   listGrid.refreshFields();
 });

This way you can see that clicking a regular record fires the event but is ignored by the summary record.

Is this intentional?

Hello Isomorphic,

could I get a confirmation that this behaviour really is intentional?

Thanks

The Grid summaryRow is not a true record in the grid, but a separate ListGrid (the Grid's summaryRow autoChild), so the rowContextClick handler isn't fired because it's not applied to the summaryRow-grid.

You can do that with this code:

        ListGrid sRow = new ListGrid();
        sRow.addRowContextClickHandler(new RowContextClickHandler() {
            @Override
            public void onRowContextClick(RowContextClickEvent event) {
                SC.say("rowContextClick");
            }
        });
        listGrid.setAutoChildProperties("summaryRow", sRow);

Group summaryRows are considered disabled, and that's why they don't fire this handler (or others) - we're looking at whether to expose the handler that would let you override this (SmartClient API, cellIsEnabled()) - we'll update here when we have more information.

By way of a quick follow-up - note that we'll add a CellIsEnabled customizer to the upcoming release, 12.0.

In the meantime, you can install the handler we noted previously onto the summaryRow autoChild to deal with Grid-level summaries, and install a regular ContextClickHandler on the grid, in which you call getRecord(getEventRow()) to retrieve the record under the mouse, including Group-level summary-rows.
