Opening a Grid Editor via Button (Getting Selected Row Number)

[TheUserRyan]

Here's my really hacky approach to creating an external "Edit" button that activates the editable fields of the selected record of a grid.

private int lastSelectedRecord;

ToolStripButton editButton = new ToolStripButton("Edit");
editButton.addClickHandler(new ClickHandler() {
    @Override
    public void onClick(ClickEvent event) {
        grid.startEditing(lastSelectedLocationRecord);
    }
});

ListGrid grid = new ListGrid();

grid.addRowMouseUpHandler(new RowMouseUpHandler() {
    @Override
    public void onRowMouseUp(RowMouseUpEvent event) {
        lastSelectedRecord = event.getRowNum();
    }
});

Is there really no way to lookup the selected record(s) and then call grid.startEditing() against those? For whatever reason:

• startEditing() with no argument just starts editing the first record--ignoring my selection.
• ListGrid doesn't seems to support retrieval of selected record *numbers*--just ListGridRecord objects.
• startEditing() only accepts record *numbers* as input

I'm sure this issue has been asked already, but I havne't figured out the right search terms. :/

getRecordIndex() goes from a Record instance to its index, so this problem has a less-than-one-line solution.
