我想创建我的自定义TabLayoutPanel
扩展,我的代码如下:定制TabLayoutPanel在GWT
public class ExpandableTabLayoutPanel extends TabLayoutPanel {
@UiConstructor
public ExpandableTabLayoutPanel(double barHeight, Unit barUnit) {
super(barHeight, barUnit);
addExpandableBehaviour();
}
private addExpandableBehaviour(){
//...
}
}
在这里,我调用它从UiBinder的:
<a:ExpandableTabLayoutPanel barHeight="20" barUnit="PX">
<a:tab>
<a:header>header</a:header>
<a:AdvancedRichTextArea styleName="{style.area}" ui:field="area"/>
</a:tab>
</a:ExpandableTabLayoutPanel>
(我是被迫的错误消息使用a:tab
/a:header
而不是g:tab
/g:header
即使我没有在我的a:
程序包/工作区中定义的选项卡和标题,但这可能不是问题)
如果@UiConstructor
注释存在超过ExpandableTabLayoutPanel像在上市后,我得到奇怪的错误:
[ERROR] [gwtreproduce] - <a:ExpandableTabLayoutPanel barHeight='20' barUnit='PX'> missing required attribute(s): arg1 barHeight Element <a:ExpandableTabLayoutPanel barHeight='20' barUnit='PX'> (:13)
当我禁用@UiConstructor
,我发现了更奇怪的错误:
[ERROR] [gwtreproduce] - Errors in 'generated://E6338B946DFB2D28988DA492134093C7/reproduce/client/TestView_TestViewUiBinderImpl.java' : [ERROR] [gwtreproduce] - Line 33: Type mismatch: cannot convert from TabLayoutPanel to ExpandableTabLayoutPanel
我在扩展TabLayoutPanel时做了什么错误?
而侧面的问题:TabLayoutPanel
构造函数没有用@UiConstructor注释并且可以在UiBinder中使用(UiBinder如何知道要调用哪个构造函数)?
