由 断了今生、忘了曾经 提交于 2019-12-31 05:28:10

Unable to use wx.NotificationMessage properly with wxPython

由 那年仲夏 提交于 2019-12-30 06:33:21
问题 I recently upgraded to the development release of wxPython (wxPython 2.9.2.4) since I needed the functionality of wx.NotificationMessage within my application. I have been trying unsuccessfully to create notification bubbles on certain user events due to something I think might be a possible bug. Before submitting such bug, I wanted to go ahead and ask the people of the mailing list what they think might be the problem and hopefully find a solution from within my code. Here is the code I have

How to change boilerplate “Sent from my iPhone” text in MFMailViewController message body?

由 和自甴很熟 提交于 2019-12-30 05:54:28
问题 I'm using the MFMailComposeViewController to send an email from within an iPhone v3.0 application. I programmatically create the message body text and display it before showing the picker. At the bottom of my message body text is the string "Sent from my iPhone." Is there anyway to modify this text or prevent it from appearing? A cursory review of the MFMailComposeViewController Class Reference and quick Googling doesn't turn up anything. Thanks in advance. 回答1: As far as I know, this is a

Python - I can't see my what my error is because the window disappears immediately

问题 I am pretty new to Python and I have been pretty annoyed with this problem. I am not sure if this matters, but I run my .py file with Python 2.7.6 with python installed on my computer, not using it on any online thing or other program. Every time I come across an error, my program works fine until it comes to the error, but the window disappears right before I can possibly read whatever the error said it was... Anyways, I haven't been able to find out what is wrong with my programming, and I

JSF converter resource bundle messages

由 会有一股神秘感。 提交于 2019-12-28 13:35:15
问题 Does anyone know where I can get a list of the converters used by JSF so I can set a custom message for them in the resource bundle? 回答1: You can find them all in chapter 2.5.2.4 of the JSF specification. Here's an extract of relevance: javax.faces.component.UIInput.CONVERSION -- {0}: Conversion error occurred javax.faces.converter.BigDecimalConverter.DECIMAL={2}: ''{0}'' must be a signed decimal number. javax.faces.converter.BigDecimalConverter.DECIMAL_detail={2}: ''{0}'' must be a signed

socket.io private message

由 北战南征 提交于 2019-12-28 03:23:11
问题 I've beeen scouring the Net with no luck. I'm trying to figure out how to send a private message from one user to another. There are lots of snippets, but I'm not sure about the client/server interaction. If I have the ID of the socket I want to send to, how do I send it to the server, and how do I ensure the server only sends the message to that one receiver socket? Is there a tutorial or walkthrough that anyone knows of? 回答1: No tutorial needed. The Socket.IO FAQ is pretty straightforward

Use case for Akka PoisonPill

由 孤街醉人 提交于 2019-12-25 15:50:20
问题 According to the Akka docs for PoisonPill : You can also send an actor the akka.actor.PoisonPill message, which will stop the actor when the message is processed. PoisonPill is enqueued as ordinary messages and will be handled after messages that were already queued in the mailbox. Although the usefulness/utility of such a feature may be obvious to an Akka Guru, to a newcomer, this sounds completely useless/reckless/dangerous. So I ask: What's the point of this message and when would one ever
