在GWT中以编程方式调用click（）函数 [英] call click() function as programmatically in GWT

问题描述

我想在GWT中调用Button的Click事件函数...
我尝试了这段代码，但它不工作..

 按钮btnAddField = new Button（）; 
 btnAddField.setText（Add）; 
 btnAddField.setWidth（225px）; 
 btnAddField.addClickHandler（new btnAddFieldButtonClickListener（））; 
 
 
 private class btnAddFieldButtonClickListener implements ClickHandler {
 public void onClick（ClickEvent event）{
 Window.alert（Called Click Event）; 
 
 
 
 
 $ b $ p 
 $ b 
这个函数在点击按钮
但调用此函数时不调用 btnAddField.click（） 
解决方案
使用这段代码解决这个问题 
 
 
  btnAddField.fireEvent（new ButtonClickEvent（））
 
 private class ButtonClickEvent extends ClickEvent {
 / *为用户点击按钮的程序化等效函数调用click（）函数* / 
} 
  
现在工作正常。

I solve that problem by using this code
btnAddField.fireEvent(new ButtonClickEvent ())

private class ButtonClickEvent extends ClickEvent{
        /*To call click() function for Programmatic equivalent of the user clicking the button.*/
    }
It is working fine now.
