You should rather encapsulate your context menu logic in a PopupMenu or
ContextMenu class. Something like this may help:
public class ContextMenu extends PopupPanel {
private final ClickListener closeListener = new ClickListener() {
public void onClick(final Widget sender) {
hide();
}
};
private final MouseListener rolloverListener
= new MouseListenerAdapter() {
public void onMouseEnter(final Widget sender) {
for(final Widget widget : items) {
if(widget == sender) {
widget.addStyleDependantName("Hover");
} else {
widget.removeStyleDependantName("Hover");
}
}
}
};
private final VerticalPanel items = new VerticalPanel();
public ContextMenu() {
super(true, false);
setWidget(items);
addStyleName("ContextMenu");
}
public SourcesClickEvents addItem(final String displayText) {
final Label label = new Label(displayText);
label.setStylePrimaryName("ContextMenu-Item");
label.addClickListener(closeListener);
label.addMouseListener(rolloverListener);
items.add(label);
return label;
}
public void show(final Widget parent, final int x, final int y) {
setPopupPositionAndShow(new PositionCallback() {
public void setPosition(
final int width, final int height) {
int px = parent.getAbsoluteLeft() + x;
int py = parent.getAbsoluteTop() + y;
if(px + width > Window.getClientWidth()) {
px = Window.getClientWidth() - width;
}
if(py + height > Window.getClientHeight()) {
py = Window.getClientHeight() - height;
}
ContextMenu.this.setPosition(px, py);
}
});
}
}
The above class adds Labels with a ClickListener to close the PopupPanel and a
MouseListener to handle rollover (Hover) styles. You can use
addItem("Delete This").addClickListener(new ClickListener() {
public void onClick(Widget sender) {
currentItem.delete();
}
});
to add your actual handling ClickListener to the Labels.
Hope that helps a bit.
