final Text text1=new Text(shell1,SWT.BORDER);
text1.setBounds(150, 100, 150, 25);
final Text text2=new Text(shell1,SWT.BORDER);
text2.setBounds(150, 150, 150, 25);
Button bt1=new Button(shell1,SWT.NONE);
bt1.setText("管理员");
bt1.setBounds(100, 220, 60, 25);
bt1.addSelectionListener(new SelectionAdapter(){
public void widgetSelected(SelectionEvent e){
if(text1.equals("admin") && text2.equals("admin")){
Shell shell5=new Shell(display);
shell5.setText("注册");
shell5.setBounds(200, 200, 400, 400);
Label lb11=new Label(shell5,SWT.NONE);
lb11.setText("用户名");
lb11.setBounds(50, 55,100 ,25 );
shell5.open();
}
}
});
shell1.open();
while (!shell1.isDisposed()){
if(!display.readAndDispatch()){
display.sleep();
}
}
display.dispose();
}
}
如果去掉if语句就可以了 这是怎么回事儿 求请教
[解决办法]
你 Text text2的类型是Text 怎么能和字符串比较大小呢，你应该获取内容去比较啊
[解决办法]
if(text1.equals("admin") && text2.equals("admin")){改成if(text1.getText().equals("admin") && text2.getText().equals("admin")){试试
