Custom tags in UiBinder files

When using a <g:LayoutPanel> in UiBinder.ui.xml files, you can specify <g:layer> tags. Some other Google-built widgets have special tags like that as well - <g:tab> even has a sub-tag, <g:header>.

How can I specify these for my own widgets?

Solution

  • The new answer to this question, after some GWT improvements, is at https://stackoverflow.com/a/11785903/439317 . Copied below to avoid moderator deletion (maybe?).

    You can use @UiChild to declare special functions in your widgets accessible in UiBinders.

    for example,

    class MyPanel extends AbsolutePanel {

    @UiChild
    public void addAt(Widget w, String parameter1, String parameter2) {
         ....

    Then, in your uiBinder, you can say

    <custom:MyPanel>
    <custom:at parameter1="HI" parameter2="Anything you like!">
        <g:AnySingleWidget />
    </custom:at>
</custom:MyPanel>
