Styling a GWT StackPanel for a Unique Look

I'm facing some difficulty with styling a stackpanel in my app. I've tried different methods, but none seem to work as expected.

The first method involves applying CSS directly to the stackpanel elements:

.gwt-StackPanel .gwt-StackPanelItem {
    font-weight: normal;
    font-size: 8pt;
    width: 100%;
    background: green;
}


.gwt-StackPanel .gwt-StackPanelItem-selected {
    background-color: red;
}

However, even after adding these styles, the default styles still show up when I test it in Firefox.

The second method I attempted was encapsulating the styles in my CSS file and using the @external attribute. This caused the GWT compiler to raise an issue with obfuscated styles. Despite resolving this, the changes still don't reflect in the stackpanel's appearance.

If anyone has any insights on how to successfully style a stackpanel in GWT, I would greatly appreciate it!

Answer №1

Although my response may be tardy, it could prove helpful to any future visitors stumbling upon this thread. If you're facing issues with your CSS being overridden by the gwt theme, chances are the gwt theme is given higher priority in your module file (.gwt.xml). To rectify this, consider incorporating your own CSS file into your module file after the gwt theme.

Here's an example of what you might find in your module file:

<!-- You have the ability to modify the theme of your GWT application by -->
<!-- selecting one of the following lines. -->
<!-- <inherits name='com.google.gwt.user.theme.standard.Standard'/> -->
<!-- <inherits name='com.google.gwt.user.theme.chrome.Chrome'/> -->
<!-- <inherits name='com.google.gwt.user.theme.dark.Dark'/> -->
<inherits name='com.google.gwt.user.theme.clean.Clean' />

After this section, simply insert a statement for your custom css file:

<!-- Including CSS Style Sheet -->
<stylesheet src="<pathToYourCSSFile>.css" />

By positioning your file after the gwt style, your styles will now take precedence over the gwt!

Answer №2

Whenever I work with the xml file of this module, I make sure to comment out the following line:

<inherits name='com.google.gwt.user.theme.standard.Standard'/>

After that, you have the freedom to apply your own styles by adding class names to widgets (such as stackPanel.setStyle...). If you still want to use a default style from GWT, you can simply duplicate it from gwt-user.jar

com.google.gwt.user.theme.standard.Standard.public.gwt.standard.standard.css
into your own css file.
