Parent JPanel - How to listen to the events generated by components of a Child JPanel? [duplicate]

眉间皱痕 提交于 2019-12-06 09:12:29
This question already has answers here : Adding ActionListener to a Panel - Panel implements ActionListener vs Panel HAS A ActionListener (2 answers) Closed 6 years ago . I made a JPanel Child which contains a couple of radio buttons in it. Whenever a radio button is clicked i want an ActionEvent to be generated from the Child also. This action event should "contain" a reference to the button which actually generated an event. This Child will be used as a component inside another JPanel Parent which will listen to the events from the Child, instead of listening to the individual radio buttons.

Detect mouse being held down

问题 I am trying to be able to detect when a mouse is held down instead of clicked. This is what I have, but instead of a click count I want to be able to detect the mouse being held down. -(void)mouseDown:(NSEvent *)event; { //instead of clickCount I want my if statement to be // if the mouse is being held down. if ([event clickCount] < 1) { } else if ([event clickCount] > 1) { } } 回答1: Presumably you want to detect whether the mouse is being held down for a certain period of time. This is pretty

Block code and wait for event handler to fire?

问题 I'm writing an application that uses a 3rd party library to process some data. In a very simplified example, I have a method which runs as a task like this: private void ProcessListOfItems(List<string> items) { while (items.Count > 0) { 3rdPartyLibObject.Process(items[0]); items.Remove(0); } } As you can see, the way my code is currently written, I remove each item from the list as soon as the Process() method returns. But it's possible that the processing of an item could fail and I need to

Is it possible to add an event handling to ZeroMQ to act when data is received/sent?

I have created two unrelated daemon processes in C in Linux Ubuntu. These processes are in the sleeping mode, they only wake up when the data is received, and perform the action implemented in the signal handler and again sleep. I have implemented this communication using SIGNAL IPC and message queue. Before sending the message, I send the signal SIGUSR1 and then send the data, and I wrote the signal handler for SIGUSR1 to perform required action. I would like to implement the same way of communication using ZeroMQ and I have been reading their guide to find out, whether ZeroMQ has any kind of

问题 Is it possible to set instance of XYChart.Series to act on setOnMouseEntered? It seems to me that one precondition to make it work would be to implement EventTarget interface.

Occasionally connected CQRS systems - Client and Server Commands - Task based screens

最后都变了- 提交于 2019-12-06 06:19:06
Premise: It is recommended that in CQRS+DDD+ES style applications use task based screens, these screens guide the user and capture intent. These task screens can also be referred to as Inductive User Interface . Some examples of UI design guidelines that can help you create mondern, user-friendly apps: Microsoft Inductive User Interface Guidelines and, Index of UX guidelines The way I understand it, the tasks , generally speaking, should line up with Commands or Functions waiting on the Server. For example, if the User makes a change to the Customer's [first name], generally speaking this

jquery datatables multiple calls to event handler with live function

时光怂恿深爱的人放手 提交于 2019-12-06 06:12:42
I am using jquery datatables to display some data. Each row has an edit button for which I register a click handler with live(), so that it works with pagination. I am doing it by class since I have to do it for every row. Something like: Datatables with live click event function This works fine. But the problem happens when user does a search again and I do an ajax request to fetch a new set of results. I just replace the existing table in the dom with a new one. Now when I click on row 1 it pops up the edit dialog for row 1. I click on row 2 it pops up the edit dialog for row 1. I click on
