我已经创建了基于GWT的组件
组件状态
package com.game.quest.ui.gwt;
import com.vaadin.shared.AbstractComponentState;
import java.util.ArrayList;
import java.util.List;
public class LinePlotState extends AbstractComponentState {
public List<DataSeries> series = new ArrayList<>();
public static class DataSeries {
public String label;
public String color;
public List<Float> data;
}
}
组件连接器
package com.game.quest.ui.gwt;
import ca.nanometrics.gflot.client.DataPoint;
import ca.nanometrics.gflot.client.SeriesHandler;
import ca.nanometrics.gflot.client.SimplePlot;
import com.game.quest.ui.gwt.LinePlotState.DataSeries;
import com.google.gwt.core.client.GWT;
import com.google.gwt.user.client.ui.Widget;
import com.vaadin.client.communication.StateChangeEvent;
import com.vaadin.client.ui.AbstractComponentConnector;
import com.vaadin.shared.ui.Connect;
@Connect(LinePlot.class)
public class LinePlotConnector extends AbstractComponentConnector {
@Override
public LinePlotState getState() {
return (LinePlotState) super.getState();
}
@Override
public SimplePlot getWidget() {
return (SimplePlot) super.getWidget();
}
@Override
protected Widget createWidget() {
return GWT.create(SimplePlot.class);
}
@Override
public void onStateChanged(StateChangeEvent stateChangeEvent) {
super.onStateChanged(stateChangeEvent);
getWidget().getModel().clear();
for (DataSeries ds : getState().series) {
SeriesHandler s = getWidget().getModel().addSeries(ds.label, ds.color);
for (int i = 0; i < ds.data.size(); i++) {
s.add(new DataPoint(i, ds.data.get(i)));
}
}
getWidget().redraw();
}
}
零件
package com.game.quest.ui.gwt;
import com.game.quest.ui.gwt.LinePlotState.DataSeries;
import com.vaadin.ui.AbstractComponent;
import java.util.Arrays;
public class LinePlot extends AbstractComponent {
public LinePlot() {
}
public LinePlotState getState() {
return (LinePlotState) super.getState();
}
public void addSeries(String label, String color, Float[] fs) {
DataSeries ds = new DataSeries();
ds.label = label;
ds.color = color;
ds.data = Arrays.asList(fs);
getState().series.add(ds);
}
}
我已经创建了
widgetset.gwt.xml<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE module PUBLIC "-//Vaadin//DTD Vaadin 7//EN" "https://raw.github.com/vaadin/gwt/master/distro-source/core/src/gwt-module.dtd">
<module>
<inherits name="com.vaadin.terminal.gwt.DefaultWidgetSet" />
<inherits name="ca.nanometrics.gflot.GFlot" />
</module>
我将此文件放在项目的
resources文件夹中。我使用
gradle-vaadin-plugin进行编译我的
build.gradle看起来像这样apply plugin: 'com.bmuschko.tomcat'
apply plugin: 'java'
apply from: 'http://plugins.jasoft.fi/vaadin-groovy.plugin'
repositories {
maven { url mavenRepoUrl }
maven { url vaadinAddonsRepoUrl }
}
buildscript {

jcenter()

}
vaadin {
version vaadinVersion
widgetset 'Widgetset'
}
[tomcatRun, tomcatRunWar]*.configure {
httpPort = 9080
stopPort = 9081
}
但是当我尝试编译它时，我遇到了这个错误

我使用
vaadinVersion=7.5.0。有什么问题？据我所知，它与
GWT有关？
最佳答案
我遇到了同样的问题，并通过增加gwt版本解决了它。
<dependency>
<groupId>com.google.gwt</groupId>
<artifactId>gwt-user</artifactId>
<version>2.7.0</version>
</dependency>
关于gwt - vaadin小部件集编译期间发生错误，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/31133280/
