I have a Swing app with a main frame and some other forms loaded inside it. I Need to implement a general method to set the hand cursor for all buttons on any form. This is similar of what we do with css on web pages ( input[type=button] { cursor:pointer; } ) Walking the tree like @Madprogrammer suggested is the method if you want to change the cursor dynamically and/or on a particular form. Just for fun (and to show-off SwingX again :) - if you want to install that cursor globally and then don't care about, install a ui-delegate which takes care of it. In SwingX, it's as simple as

The title mostly explains what I need. I have a textbox that I continuously examine for data validity using the _keypress procedure. If the user enters ( then I auto-fill it for them by typing the closing parenthesis ) . The result is () and the cursor is at the end of the textbox. My question is, how can I push the cursor back one step to put it between the two parenthesis?

Then I read somewhere to queue this action like this : myListView.post(new Runnable() { public void run() { myListView.scrollTo(0, 0); } }); but this doesn't work either. How can I keep the ListView at the top when its content changes? EDIT: Just for try, I added a button and called scrollTo() in its

cursor.fetchone()与cursor.fetchall()的区别： cursor.fetchone()：只能显示一个数据 cursor.fetchall()：才能显示查出来的所有数据 Pymsql的其他常用方法 import pymysql #连接数据库 db = pymysql.connect("localhost","admin","Cesare@qq","dbpymysql") #使用cursor()方法创建一个游标对象 cursor = db.cursor() #使用execute()方法执行SQL语句 cursor.execute("SELECT * FROM order_info") # 使用fetchone() 获取一条结果数据 result = cursor.fetchone() # 只显示一行结果 #使用fetall()获取全部结果数据 data = cursor.fetchall() #关闭游标和数据库的连接 cursor.close() db.close() # 更新SQL cursor.execute(sql) db.commit() 来源： https://www.cnblogs.com/CesareZhang/p/11846883.html
