问题描述
我正在使用Gxt。我需要将焦点设置为页面上第一个启用的字段。但是我有很多页面,我想集中这种行为。在Gxt中缺少文档,所以我想知道是否有人遇到了这样的问题,可以帮助我。现在每个组件的类都是这样的
protected void resetFocus(){
combobox.focus();
@Override
public void show(){
super.show();
resetFocus();
}
我找到了com.extjs.gxt.ui.client。 aria.FocusManager ,但绝对不清楚,我该如何使用它。或者也许也可以根据焦点在组件上进行连接。我可以将 resetFocus 方法移动到父类。
这样的行为
<$ (){$ b $ getFocusChain()。get(0).focus(); *
}
protected void resetFocus >
基于最后一个响应,我通过执行以下操作在GXT3窗口中工作: / p>
@Override
public void show(){
super.show();
Scheduler.get()。scheduleDeferred(new Scheduler.ScheduledCommand(){
@Override
public void execute(){
field.focus();
}
});
$ b 这种方式当窗口打开时,字段有焦点,你可以开始输入。
I am working with Gxt. I need to set focus to the first enabled field on the page. But I have a lot of pages and I want to centralize that behaviour. There is a lack of documentation in Gxt so I wonder if somebody has met such a problem and can help me.
Now it goes like that in each component's class
protected void resetFocus() {
combobox.focus();
}
@Override
public void show() {
super.show();
resetFocus();
}
I have found com.extjs.gxt.ui.client.aria.FocusManager but is absolutely unclear how can I use it. Or maybe It is also possible to get chain of fields as they go on the component according to the focus. And I can move resetFocus method to the parent class.
Smth like that
protected void resetFocus() {
*getFocusChain().get(0).focus();*
}
解决方案 Based on the last response, I got this to work in a GXT3 window by doing the following:
@Override
public void show() {
super.show();
Scheduler.get().scheduleDeferred(new Scheduler.ScheduledCommand() {
@Override
public void execute() {
field.focus();
}
});
}
This way when the window opens, the field has focus and you can begin typing.
