SmartGWT has this property for a TreeGrid object:

employeeTreeGrid.setSelectionAppearance(SelectionAppearance.CHECKBOX);

This by default ‘prepends’ every nodes (including root) with checkbox.
(Just making myself clear.)

Also, I am aware of this similar solved question:
GWT tree with checkbox:How to get all checked tree items?

However, I do not seek this kind of solution..
What I’m looking for is a more efficient way, where I don’t have to loop through 1000 items.

Is there any way to do this, if possible, using the widget I am using now?
If not, is there any other way, using other widget?

Thank you very much!

    I think as you use SelectionAppearance.CHECKBOX you tell to the grid that the selected records are marked by the checkbox field value. So every time you check one you select a record.
    You can get the set of selected records by either getSelection() method or getSelectedRecords(boolean) because of deprecation of the previuous one.
    You can have a look at the code of this example of the smartgwt showcase.
