Question

So my software is displaying a flextable (the data is grabbed and displayed from a database) with users allowing to click on a checkbox to select a data.

//users is the flextable object.
userCheck = new ClickHandler() {
        public void onClick(ClickEvent event) {
            CheckBox src = (CheckBox) event.getSource();
            for (int i = 1, n = users.getRowCount(); i < n; i++) {
                CheckBox box = (CheckBox) users.getWidget(i, 0);

                if (!box.equals(src)) {
                    box.setValue(false, false);
                }
            }
            removeUserButton.setEnabled(src.getValue());
            editUserButton.setEnabled(src.getValue());

        }
    };

The code above works, but now I’m trying to implement an action where instead of the user clicking on the checkbox, I want the user to click on a row (which ever cell of the table) and make the whole row (where the user have selected) to be highlighted. So I implemented this code below but so far it doesn’t work (like the mouseclick won’t register, I’ve yet to implement the color stuff yet.. 🙁 ). Any suggestions?

userRowCheck = new ClickHandler() {
        public void onClick(ClickEvent event) {
            Cell src = users.getCellForEvent(event);
            int rowIndex = src.getRowIndex();
            System.out.println("Cell Selected: userRowCheck Handler, rowIndex: " + rowIndex);
            //This is just to check if this method is even called out. And well, it doesn't.
        }
    };

Thanks very much!!!!

If you added userRowCheck to the FlexTable : myFlexTable.addClickHandler(userRowCheck); it should work. Just make sure you test src for null, because if you didn’t put a widget in a cell and the user clicks on that cell it returns null.
