It has Controls property (TCollection descendant) and direction (vertical/horizontal). Every collection item has a reference to a control on the form (that can be simple control or another TControlAligner) and different properties. The main property of the item that affects the position is Cells which is either weight (equivalent of % of html tables) or pixels, and when all requirements is set and this TControlAligner is placed (or its bounds changed) it does the best it can do with all the requirements of the collections items (as with html tables where cells can require % of the width or exact pixels).

The best way to see what MiGLayout can do, is to download the demo jar file which has a lot of examples built-in, then play around with those examples. You can even right-click on each example to do live editing, or enable the debug-mode to see how the layout manager does it's calculation and layout. There was also a nice UI competition between layout managers. A UI Form was designed, and people could submit how to recreate that form using various layout managers available. MiGLayout had very little code compared to most alternatives, and the result was often more flexible too. If you read the MiGLayout white paper, you will learn some more of the advanced features which are mind blowing! The author thought of everything. Automatically managed button orders per platform (OK, Cancel vs Cancel,OK etc), automatic style defaults per platform (border sizes around components, default sizes of buttons etc), layouts can be described in any units like pixels, mm, cm, inchs, dpi independent, alignment or anchoring or resizing can be described really simple or even by using complex expressions.

The LCL developers missed that simple fact, and continue to add layout features to every single control, instead of letting the user choose layout managers from an (extensible) set of predefined layout managers.

Even if KSD or now FireMonkey supports ARM Linux this does not mean anything for Android. While Android does support native Linux applications it does not have a X server.

And you can't test this with the emulator, you need 100+ devices to make sure it works everywhere. I don't know what Qt did, but I bet it doesn't work with half of the virtual keyboards out there. qt specifies Gingerbread (2.3) afaik. I may be wrong here. Besides, it is a simple XML configuration file for the keyboard mapping and if you want to use it: JNI is inconvienient but NOT difficult. There is C++ code for IME softkeybord bindings available from the android developer website. From the platform highlights 2.3: *Native input and sensor events* Applications that use native code can now receive and process input and sensor events directly in their native code, which dramatically improves efficiency and responsiveness. Native libraries exposed by the platform let applications handle the same types of input events as those available through the framework. Applications can receive events from all supported sensor types and can enable/disable specific sensors and manage event delivery rate and queueing. 2 Action completion. In standard apps you can for example click on a video and complete the action with any installed video player, and this requires access to the SDK which is only available from the Java side or from the bindings which I built See the 2.3 platform highlights above. 3 Application lifecycle, also something different from other platforms What do you mean? It isn't.( persé). If your APK is packaged and signed correctly, an Android machine that isn't supported won't see your app in the market. If that is what you mean. I think this is rather neat/cute/wonderful and saves headaches. 4 Orientation change, the app needs to respond to it. With standard widgets it automagically works. Also lower than 2.3 issue, but you have to provide for it in code or use a browser approach, that's true. I must say I am still playing and can't say I have things working in a generic way. Just that some code that works in the emulator also works on my Android machine and in a predictable manner. ___ fpc-devel maillist - fpc-devel@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-devel

But I already foresee a difficulty in porting existing apps because the controls and fonts in Android are much bigger then in desktop platforms. Fixed-size layouts will have a hard time being ported. This could be fixed by introducing some phone-like layouts in the LCL, like the linear layouts from Android. As far as I'm currently aware of the state of LCL-fpGUI (I never tested it yet) I'll need to implement TTreeView... If you ever do, please implement it in the Custom Drawn Package from Lazarus, then we can use this TCDTreeView in both LCL-Android and LCL-fpgui =) -- Felipe Monteiro de Carvalho ___ fpc-devel maillist - fpc-devel@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-devel

In our previous episode, Dimitri Smits said: Florian, has anybody from Embarcadero approached you on this? I wonder if they know that any modifications they make to the FPC compiler must be made available as open-source? The compiler is GPL'ed after all. contrary to popular belief, it is not so that if you GPL something, everyone gets your source (ie: the community; by way of give back). If you take a open source project ((L)GPL that is, not talking about MPL/MIT/BSD/...), and you modify it, then sell it, the licence does not require you to give away the source to everyone! Only to your customers(/competitors) who bought the program! As Jonas said, those can pass it on freely. And due to the scale of an Embarcadero launch (it is not 3 or 4 private customers Embarcadero sells too) that is nearly the same. Likewise, when you take such a project with such a licence, maybe even straight GPL, and modify it, but only use it in-house, then you owe nobody anything. (since the source is handed over to the client, ie: yourself) btw, I even believe that you can devise a licence that is GPL compatible (copyleft), but that disallows redistribution/resell. Like a bit of an NDA. And what is that belief founded on? :-) Anyway, there are more gotchas. They could e.g. have stuff like linkerscripts in a external files, and since they are not GPLed, not deliver them. (as in the case of Microchip gcc, where all linker scripts and all headers for the (many) individual parts were not included). All being said, I wouldn't get my hope up. Most changes will probably be interoperability with their own toolchain. (e.g. I can imagine they change the cmdline module to be (more) dcc compat). And it is only a stopgap solution for an year. A handful of minor bugfixes is the best we can hope for. Personally I think bugreports from users themselves will be a bigger treasure than what the GPL will deliver. ___ fpc-devel maillist - fpc-devel@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-devel

I would not call bug reports treasure. Patches, maybe, but bug reports not. Especially for the iOS platform, which Apples makes very painful to develop for at a low level if you don't go the jailbreak way.

For good or worse. I haven't seen much open source spirit from them yet. b) at least the linker script example cannot happen, because Apple's linker simply does not support linker scripts I named that example because it is a GPL cirumvention case that actually happened . Not because I expect it to happen in this case. ___ fpc-devel maillist - fpc-devel@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-devel

People should be happy that there is a pretty large commercial vendor which provides an professional object pascal development environment. Even if one doesn't use it, one should be aware that it really helps to keep pascal (well, they call it Delphi ;)) a living language. ___ fpc-devel maillist - fpc-devel@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-devel

Nobody can see their compiler code. Good news is that any modifications or bug fixes they make, they will have to share. But then comes the second question, how do you monitor something like that? If someone gets access to the Embacadero supplied compiler(and some of the professional people probably will), they can run a differential test suite run for ARM and see if they fixed any of the remaining problems :) ___ fpc-devel maillist - fpc-devel@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-devel
