问题描述
我找到了一个如何在GWT上的TextArea上捕获Paste事件的例子,但它不起作用。
public MyTextArea(){
super();
sinkEvents(Event.ONPASTE);
}
@Override
public void onBrowserEvent(Event event){
super.onBrowserEvent(event);
switch(event.getTypeInt()){
case Event.ONPASTE:
System.out.println(Paste Pastected);
Window.alert(Paste Works !!! Yippie !!!);
休息;
$ b $ p
$ b 问题是我从来没有进入onBrowserEvent ..任何建议?
Thnx
解决方案
public class Starter implements EntryPoint {
$ b $ @Override
public void onModuleLoad(){
RootPanel.get()。add(new MyTextArea ());
}
class MyTextArea extends TextArea {
public MyTextArea(){
super();
sinkEvents(Event.ONPASTE);
}
@Override
public void onBrowserEvent(Event event){
super.onBrowserEvent(event);
switch(event.getTypeInt()){
case Event.ONPASTE:
System.out.println(Paste Pastected);
Window.alert(Paste Works !!! Yippie !!!);
休息;
}
}
}
}
开你在测试什么浏览器?
I found an example of how to catch the Paste event on a TextArea on GWT but it doesn't work.
public MyTextArea() {
super();
sinkEvents(Event.ONPASTE);
}
@Override
public void onBrowserEvent(Event event) {
super.onBrowserEvent(event);
switch (event.getTypeInt()) {
case Event.ONPASTE:
System.out.println("Paste Detected");
Window.alert("Paste Works!!! Yippie!!!");
break;
}
}
The problem is that I never enter to onBrowserEvent ... Any suggestion ? Thnx
解决方案
Works for me as intended:
public class Starter implements EntryPoint {
@Override
public void onModuleLoad() {
RootPanel.get().add(new MyTextArea());
}
class MyTextArea extends TextArea {
public MyTextArea() {
super();
sinkEvents(Event.ONPASTE);
}
@Override
public void onBrowserEvent(Event event) {
super.onBrowserEvent(event);
switch (event.getTypeInt()) {
case Event.ONPASTE:
System.out.println("Paste Detected");
Window.alert("Paste Works!!! Yippie!!!");
break;
}
}
}
}
On what browser are you testing it?
