I just wanted to update on the Drop Down List Box,
GWT Incubator
Drop Down List BoxNot planned at this time, but some people use a vertical
MenuBar<http://google-web-toolkit.googlecode.com/svn/javadoc/latest/com/google/gwt/user/client/ui/MenuBar.html>
to
achieve the same effect
While trying to achieve the above I managed to get a drop down or drop up
list in a different way, with popup ups and menuBar. Hope this helps if you
are looking to achieve something similar. While I tried to use a MenuBar
instead of a Popup it always lists down which I didn't want. It is
definitely nicer when it lists up !! There are other options as well. You
can use labels instead of a the menubar. You just have to add the labels in
the PopupPanel in a vertical Panel, and define a clickHandler for each
Label. Please do update if you have a better solution.
// below PopUp panel to show the options that the user can
click
PopupPanel mainPopup = new PopupPanel(true, true);
// Commands to be executed when user clicks the option
Command option1 = new Command() {
@Override
public void execute() {
Window.alert("Option 1");
select.setText("Option 1");
}
};
Command option2 = new Command() {
@Override
public void execute() {
Window.alert("Option 2");
select.setText("Option 1");
}
};
// MenuBar that will contain the options
MenuBar options = new MenuBar(true);
options.addItem("Option 1", option1);
options.addItem("Option 2", option2);
// A Label that triggers the PopUp
Label select = new Label("Select");
// Click handler for the Label
select.addClickHandler(new ClickHandler() {
@Override
public void onClick(ClickEvent event) {
if (!mainPopup.isShowing()) {
mainPopup.showRelativeTo(select);
} else {
mainPopup.hide();
}
}
});
// finally we add the options to the popup
mainPopup.add(options);
}
** I wish there was a code box widget here :-) so that I can easily show the
code I want in a preformatted way. ***
