public class TrackerEntryPoint implements EntryPoint {
private EventPreview keyBoardShorcuts;
private HorizontalPanel hPanel;
public void onModuleLoad() {
hPanel = new HorizontalPanel();
keyBoardShortCut();
RootPanel.get().add(hPanel);
}
public void keyBoardShortCut() {
hPanel.sinkEvents(Event.ONKEYDOWN);
keyBoardShorcuts = new EventPreview() {
public boolean onEventPreview(Event event) {
boolean propagate = true;
int type = DOM.eventGetType(event);
if (type == Event.ONKEYDOWN ) {
int keyCode =
DOM.eventGetKeyCode(event);
switch(keyCode) {
case TrackerKeyCode.CODE_F1:
showHelp();
propagate = false;
break;
}
}
if ( !propagate) {
DOM.eventPreventDefault(event);
}
return propagate;
}
};
DOM.addEventPreview(keyBoardShorcuts);
}
private void showHelp() {
WindowPanel help = new WindowPanel("keyBoardShortCut");
VerticalPanel vPanel = new VerticalPanel();
HTML j = new HTML("J : ");
vPanel.add( j);
help.setWidget(vPanel);
help.center();
help.show();
}
}
