To allow the time zone of the clock widgets to be changed, a drop-down box (known as Combo) as well as a Button will be added to the view. The Combo will be created from a set of ZoneId instances.
Create a
timeZonesfield in theClockViewclass:private Combo timeZones;
At the end of the
createPartControlmethod, add this snippet to create the drop-down list:public void createPartControl(Composite parent) { ... timeZones = new Combo(parent, SWT.DROP_DOWN); timeZones.setVisibleItemCount(5); for (String zone : ZoneId.getAvailableZoneIds()) { timeZones.add(zone); } }Run the target Eclipse and open the Clock View again; a list of time zone names will be shown in a drop-down:
It's conventional to set the focus on a particular widget when a view is opened. Implement the appropriate call in the
ClockViewmethodsetFocus:public void setFocus() { timeZones.setFocus(); }Run Eclipse and show the Clock View; the time zone drop-down widget will be focused...
