            }
            event.stopPropagation();
        }
    }, ClickEvent.getType());
    /* Don't start moving the window when clicking close button */
    closeButton.addDomHandler(new MouseDownHandler() {

        @Override
        public void onMouseDown(MouseDownEvent event) {
            event.preventDefault();

        }
    }, MouseDownEvent.getType());
    MouseHandler mouseHandler = new MouseHandler();
    header.addDomHandler(mouseHandler, MouseDownEvent.getType());
    header.addDomHandler(mouseHandler, MouseUpEvent.getType());
    header.addDomHandler(mouseHandler, MouseMoveEvent.getType());
}

Example 2 with MouseDownHandler

use of com.google.gwt.event.dom.client.MouseDownHandler in project rstudio by rstudio.

the class ModifyKeyboardShortcutsWidget method addHandlers.

private void addHandlers() {
    table_.addCellPreviewHandler(new CellPreviewEvent.Handler<KeyboardShortcutEntry>() {

        @Override
        public void onCellPreview(CellPreviewEvent<KeyboardShortcutEntry> preview) {
            Handle shortcutsHandler = shortcuts_.disable();
            int column = preview.getColumn();
            if (column == 0)
                onNameCellPreview(preview);
            else if (column == 1)
                onShortcutCellPreview(preview);
            else if (column == 2)
                onNameCellPreview(preview);
            shortcutsHandler.close();
        }
    });
    table_.addColumnSortHandler(new ColumnSortEvent.Handler() {

        @Override

            List<KeyboardShortcutEntry> data = dataProvider_.getList();
            if (event.getColumn().equals(nameColumn_))
                sort(data, 0, event.isSortAscending());
            else if (event.getColumn().equals(shortcutColumn_))
                sort(data, 1, event.isSortAscending());
            else if (event.getColumn().equals(typeColumn_))
                sort(data, 2, event.isSortAscending());
            updateData(data);
        }
    });
    // Fix a bug where clicking on a table header would also
    // select the cell at position [0, 0]. It seems that GWT's
    // DataGrid over-aggressively selects the first cell on the
    // _first_ mouse down event seen; after the first click,
    // cell selection occurs only after full mouse clicks.
    table_.addDomHandler(new MouseDownHandler() {

        @Override
        public void onMouseDown(MouseDownEvent event) {
            Element target = event.getNativeEvent().getEventTarget().cast();
            if (target.hasAttribute("__gwt_header")) {
                event.stopPropagation();
                event.preventDefault();
            }
        }
    }, MouseDownEvent.getType());
