Legacy theme in MPR
By default the theme used with MPR is "valo"
and this can be changed with
adding the MprTheme
annotation with the wanted theme name to your AppShellConfigurator
configuration class.
Note
| Runtime changing of the theme isn’t supported |
@MprTheme("reindeer")
public class Configuration implements AppShellConfigurator {
}
public class MainLayout extends Div implements RouterLayout {
}
@Route(value = "", layout = MainLayout.class)
public class RootTarget extends Div {
public RootTarget() {
LegacyWrapper addressbookWrapper = new LegacyWrapper(
new AddressbookLayout());
add(addressbookWrapper);
}
}
The theme can be a old legacy styles.css
theme or a styles.scss
theme.
With a Sass-based theme, on-the-fly compilation works out of the box without any changes.
Using your custom theme
Using your own Vaadin legacy theme remains the same as it was. Create your theme by following the instructions in the themes documentation for Vaadin 7 or Vaadin 8.
Then add the @MprTheme
annotation with your theme name on the
AppShellConfigurator
instance and your theme is used for the legacy
framework part.
Note
|
Legacy theme is applied only when a view has legacy components
Styles for non-legacy components shouldn’t be included in the legacy theme.
