[Estimated Reading Time: 5 minutes] A comment from Kevin P brought a build automation tool to my attention this evening, called Train. Train is a JavaScript based build automation tool from a little company called RemObjects. It is written in Oxygene but the API provides specific support for Delphi. It’s an open source project and free (as in beer). So I decided to check it out.
[Estimated Reading Time: 4 minutes] Here in Aotearoa there is a beer company called “Tui”, named in turn for a native bird. As well as a series of TV ads voiced by the great Tom Baker, Tui are famous here for their “Yeah, right!” billboard ads. I felt compelled to make one for Delphi.
[Estimated Reading Time: 3 minutes] A while ago Marco Cantu posted about an issue with implementing ShowModal in FireMonkey, specifically with reference to the difficulties this entailed on iOS and Google Android platforms. Chris Rolliston recently picked this same topic up and highlighted some problems that still remain in the FireMonkey “solution”. Both Marco and Chris however have missed a key point. Neither Google nor Apple are stupid.
[Estimated Reading Time: 6 minutes] Sometimes when you launch a thread you don’t know when it will complete whatever processing it is tasked with. Sometimes you do. Sometimes it may never complete and will require that you expressly terminate it. Usually any given thread will have a lifecycle that is at least consistently one or the other, but sometimes you will come across an awkward thread which is not so straightforward. Sometimes you will be creating a thread on behalf of somebody else who is making these decisions.
[Estimated Reading Time: 3 minutes] In a comment on my previous post, David Heffernan noted that the IDE messes around with other parts of the application DPR in addition to the uses list. He is right. Another area that the IDE likes to muck about with is the code in the DPR begin .. end itself ! Fortunately there is a simple way to avoid that also.
[Estimated Reading Time: 3 minutes] Over on stackoverflow, Ann Gossard had a question about using an $ifdef in the project (DPR) uses list to use one unit in preference over another, specifically in debug builds. In this situation, it immediately occurred to me that unit aliases might be creatively deployed. What follows is a slightly expanded version of the answer I posted to that question.
[Estimated Reading Time: 4 minutes] Francois Piette recently posted a solution to obtaining the screen position of a menu item involving using a “hacker” class. There is however a safer, more direct mechanism which I hope Francois won’t mind me sharing and a far less safe related hacking technique that his post brought to mind.
[Estimated Reading Time: 6 minutes] Although I am using Oxygene a lot these days, Delphi remains my tool of choice for Win32 (and x64) development, together with the VCL. Hence this post. A long time ago, in a galaxy far far away, Delphi was a Windows only development tool. 16 was the number of the bits with which it was concerned, and 1 was the number of threads in the process (though it was not called a thread). It was a simpler time. Then the bits were doubled and the number of threads did multiply, but it was important still that some things happened only on the original thread, though for a time a blinded eye could be turned since – no matter the plurality of threads – with only one piece of silicon to share, only one thread could be running at any one time. Yet lo, TThread.Synchronize() was conceived.
[Estimated Reading Time: 4 minutes] Last week I picked up a Nokia 520 Windows Phone for what I consider to be an absolute bargain price (well under the NZ$299 RRP) specifically as a development handset to allow me to explore the Windows Phone support offered by Oxygene. I’ve only just started down this road but have already come across a couple of things that might help people who might be scratching their heads (as I was) when getting started.
