### Question:
DropDownTextField extends JTextField implements GComponent { JList<T> getJList() { return list; } DropDownTextField(DropDownTextFieldDataModel<T> dataModel);  DropDownTextField(DropDownTextFieldDataModel<T> dataModel, int updateMinDelay); @Override void setText(String text); boolean isMatchingListShowing(); void setConsumeEnterKeyPress(boolean consume); void setIgnoreEnterKeyPress(boolean ignore); void setMatchingWindowHeight(int height); void addDropDownSelectionChoiceListener(DropDownSelectionChoiceListener<T> listener); void addCellEditorListener(CellEditorListener listener); void removeCellEditorListener(CellEditorListener listener); T getSelectedValue(); void setSelectedValue(T value); void closeDropDownWindow();  }### Answer:
@Test public void testClickingList() { typeText("d", true); assertMatchingWindowShowing(); int index = 1; JList<String> list = textField.getJList(); Point clickPoint = list.indexToLocation(index); String clickedItem = list.getModel().getElementAt(index); int clickCount = 1; clickMouse(list, MouseEvent.BUTTON1, clickPoint.x, clickPoint.y, clickCount, 0); assertMatchingWindowShowing(); assertNoSelectedListItem(); clickCount = 2; clickMouse(list, MouseEvent.BUTTON1, clickPoint.x, clickPoint.y, clickCount, 0); assertMatchingWindowHidden(); assertNoSelectedListItem(); assertSelectedValue(clickedItem); }
