I am trying to edit the Text of the textfield in Vaadin. I created a file (\WebContent\VAADIN\themes\loginthemes\style.css) with ONLY the following information:
textstyle {
font-family: HelveticaRounded;
font-size: 40px;
font-style: bold;
}
And inside my java file I have the following:
TextField username = new TextField("Username: ");
username.setStyleName("style");
// I also tried username.setStyleName("loginthemes");
The text for the textfield stays the same.
As Jan Galinski said, you should define a proper theme.
For one named "logintheme" you should create VAADIN/theme/logintheme/style.scss as :
#import "../reindeer/reindeer.scss";
.logintheme {
#include reindeer;
.textstyle {
font-family: HelveticaRounded;
font-size: 40px;
font-style: bold;
}
}
Tell the UI to use it:
#Theme("logintheme")
public class MyUI extends UI {
}
Also, your usage of setStyleName() is incorrect: the parameter is the name of your CSS class, not the name of the theme.
So in your case, it should be:
TextField username = new TextField("Username: ");
username.setStyleName("textstyle");
You must specify the theme on your UI class.
#Theme("logintheme")
public class MyUI extends UI {
}
also, you should reference an existing theme via #import, else your theme will look very "reduced".

Is there a way to edit a custom css class of mind to enable these css style rules
http://www.gwtproject.org/javadoc/latest/com/google/gwt/user/client/ui/MenuBar.html
I currenly created my MenuBar through code like :
MenuBar menuButton = new MenuBar();
menuButton.addStyleName(masterPanel.getmenuBar());
Using the interface to get the css class:
interface Style extends CssResource {
String menuBar();
String action();
}
I have a css class that can ONLY edit my menu bar:
.menuBar {
cursor: default;
text-align: center;
background: transparent;
border: none;
color: white;
text-shadow: none;
font-size: 16px;
}
Is there a way i can access styles like:
.gwt-MenuBar-horizontal
.gwt-MenuBar-vertical
.gwt-MenuBar .gwt-MenuItem
.gwt-MenuBar .gwt-MenuItem-selected
.gwt-MenuBar .gwt-MenuItemSeparator
.gwt-MenuBar .gwt-MenuItemSeparator .menuSeparatorInner
.gwt-MenuBarPopup .menuPopupTopLeft
First i added your css snippet to the .css of the project and added it to the menu bar with menuButton.setStyleName("menuBar"). Then i added the following to the project css class (as an example) :
.gwt-MenuItem-selected
{
color:red !important;
}
Now the first menuBar style is enabled and the additional style is set, too. Its necessary to use the !important to override the default properties.
I want to generate a Cell for a CellWidget with the UiBinder (UiRenderer). What I did to generate the cell is in MyCell.java:
public class MyCell implements AbstractCell<MyDto> {
public interface Resources extends ClientBundle {
#Source({Css.DEFAULT_CSS })
Css css();
}
public interface Css extends CssResource {
String DEFAULT_CSS = "test/MyStyle.css";
String test();
}
interface MyUiRenderer extends UiRenderer {
void render(SafeHtmlBuilder sb, String name, SafeStyles styles);
}
private static MyUiRenderer renderer = GWT.create(MyUiRenderer.class);
Resources resources = GWT.create(Resources.class);
#Override
public void render(SafeHtmlBuilder safeHtmlBuilder, MyDto model) {
SafeStyles style = SafeStylesUtils.fromTrustedString(resources.css().test().toString());
renderer.render(safeHtmlBuilder, model.getName(), style);
}
}
My MyCell.ui.xml file looks like this:
<!DOCTYPE ui:UiBinder SYSTEM "http://dl.google.com/gwt/DTD/xhtml.ent">
<ui:UiBinder xmlns:ui='urn:ui:com.google.gwt.uibinder'>
<ui:with field="name" type="java.lang.String" />
<ui:with field='styles' type='com.google.gwt.safecss.shared.SafeStyles'/>
<div style="{styles}"><ui:text from="{name}" /></div>
</ui:UiBinder>
MyStyle.css:
.test {
background-color: red;
font-size: 20px;
display: flex;
...
}
When I run my code I get the following error:
[DEBUG] [mobile] - Rebinding test.client.app.MyCell.MyUiRenderer
[DEBUG] [mobile] - Invoking generator com.google.gwt.uibinder.rebind.UiBinderGenerator
[ERROR] [mobile] - java.lang.String required, but {styles} returns com.google.gwt.safecss.shared.SafeStyles: <div style='{styles}'> (:9)
[ERROR] [mobile] - Deferred binding failed for 'test.client.app.MyCell.MyUiRenderer'; expect subsequent failures
[ERROR] [mobile] - (GWT.java:72) 2014-06-08 17:15:05,214 [FATAL] Uncaught Exception:
Then I tried to this:
<ui:with field="styles" type="java.lang.String" />
in my UiBinder but it does not work.
How can I use css style from a CssResource in my UiRenderer?
<div style="{styles}">
Two problems here. First, in order to change the style of an element, you have two options, setting the style attribute to include specific properties, or set the class attribute to point to a class you’ve defined in CSS somewhere. So, you really want to set class here, not style.
Second, you created a css class called "test", but are assigning here just the whole interface, styles. Instead, reference styles.test:
<div class="{styles.test}" />
Edit: one final piece you may be missing (but since "This does not work" is so vague I don't know if this is your actual problem): I don't see any call to ensureInjected() in your example. Make sure you call this on your Css instance before using it.
you have to put .asString after styles in the xml:
<div style="{styles.asString}"><ui:text from="{name}" /></div>
I have little issue with CssResource in GWT. I want to change styles of AbsolutePanel and label, but it doestnt run. When I add style class with setStyleName method, nothing is happend.
In this snippet of code I use a resource :
public CustommerView() {
MyResource cssResource = GWT.create(MyResource.class);
MyCss myCss = cssResource.css();
AbsolutePanel basePanel = new AbsolutePanel();
initWidget(basePanel);
basePanel.setStyleName(myCss.rootPanel());
Label label = new Label();
label.setText("Im label");
label.setStyleName(myCss.label());
basePanel.add(label);
}
This is my interface which extends CssResource:
public interface MyCss extends CssResource {
/**
* Method for return command button class name
* #return command button class name
*/
public String rootPanel();
public String label();
}
This is my css file, which is next to MyCss interface on filesystem :
.rootPanel {
position:absolute !important;
top:0px;
left:0px;
background-color:yellow !important;
height: 20px !important;
width: 18px !important;
}
.label {
color:red;
}
Custommer view is GWT Composite. When I want to move on view, i call simply RootPanel.get("mainArea").add(view.asWidget) in presenter. mainArea is div element.
When I pasted css class in css file in web inf, everything run ok. Can someone give me the point how to solve this issue? Thanks.
The ensureInjected() call is missing.
How to update the style of a JSF component at runtime, I must clarify that I want to change the position of the component and in some cases hide it.
<ui:define name="reverso" id="reverso" >
<!-- Logo Estado Próspero -->
<p:graphicImage value="./resources/oficiales/prospero.png" style="width: 90px; height: 50px;position: relative; left: 150px" />
<h:form id="dataRfc">
<h:outputText id="display_rfc" rendered="true" value="#{IDWizard.rfc}" binding="#{IDWizard.outRfc}" style="color: #333333;text-align:center;margin-top: 30px" />
</h:form>
</ui:define>
public void setNoPersonal(String noPersonal) {
this.noPersonal = noPersonal;
this.outNombre.setValue(this.noPersonal);
this.outNombre.setRendered(true);
this.outRfc.setStyle("text-align:left;color:red;margin-top:2px");
//component.getAttributes().put("style", "color:red");
this.outRfc.setRendered(true);
}
You can just use EL expressions in the style and styleClass attributes. You can use the conditional operator ?: in EL to print different strings based on a boolean condition.
E.g.
<h:someComponent styleClass="#{bean.show ? 'show' : 'hide'}" />
with this getter
public boolean isShow() {
return show;
}
and this CSS
.show {
display: block;
}
.hide {
display: none;
}
Note that the above still renders the component to the client side, so you would be able to toggle the visibility using plain JavaScript.
Or, if you actually want to show/hide it entirely server side, then you could use the rendered attribute for this instead. It also just accepts EL expressions:
<h:someComponent rendered="#{bean.show}" />
You only need to keep in mind that when this evaluates false, then this component is not present in the client side at all, so you won't be able to show it again using plain JavaScript or Ajax. When showing it using Ajax, you need to re-render its parent component instead.
Update based on your new code snippet, this is not the right way. You should not bind the component to the bean for this. You should also define CSS styles in its own .css file which is much easier to maintain and keeps your bean and view from specific CSS clutter.
E.g. (I randomly guess that the styles are dependent on some kind of error/success state)
<h:outputText id="display_rfc" value="#{IDWizard.rfc}" rendered="#{IDWizard.show}"
styleClass="#{IDWizard.success ? 'success' : 'error'}" />
with those getters
public boolean isShow() {
return show;
}
public boolean isSuccess() {
return success;
}
and this CSS
.success {
text-align: center;
color: #333333;
margin-top: 30px;
}
.error {
text-align: left;
color: red;
margin-top: 2px;
}
You just have to set those booleans accordingly in bean's (post)constructor or action(listener) method.
saveButton.setStylePrimaryName("jtyfj");
If I do that to a button, it removes the default "gwt-button' class and replaces it with 'jtyfj'. My question is, is there a way to apply this yo all buttons by default. I'd really rather not have any default gwt-styles being referenced.
Also, is there a way to do it with a ClientBundle CSSResource?
Why don't you just use another class that extends Button and set the style in the constructor?
public class StyleButton extends Button {
public StyleButton() {
this.setStylePrimaryName("jtyfj");
}
}
Whenever you create an instance of StyleButton it will have the style you want.
I you want the style to be applied to ALL the buttons in your app. You may as well customize the GWT Standard Theme css and replace the desired style with your own:
.gwt-Button {
/* Replace the following properties with your own */
margin: 0;
padding: 3px 5px;
text-decoration: none;
font-size: small;
cursor: pointer;
cursor: hand;
background: url("images/hborder.png") repeat-x 0px -27px;
border: 1px outset #ccc;
}
It will avoid creating a new control for each widget you want to customize.
