Hi everybody, I'm using Delphi 12 on Windows for Desktop applications. I've an FMX project done in single threaded mode (classical without threads) with timers and I have a problem with animation of objects inside frames! The project is structured like that : A main form with 2 timers and 3 layouts (Top, Main, Bottom). 1 - The first timer is in charge to display successively TFrames regarding a process inside the layouts 2 - The second one is in charge of the standby mode management A second form with 5 timers in charge of the communication with a PLC 1 - The 5 timers have different frequencies in order to read different values of the PLC (500 ms, 1s, 1.5s, etc) In the main form, on specifics frames, I've some objects (like TArc or TRectangle, etc.) that are animated by using TFloatAnimation. My problem is that these animations are lagging. Trying to analyse the problem I made a try without timers and it seems to work smoothly but it is hard to conclude if it is only the timers! I would like to create some threads to eliminate the timers and my idea is to create one thread by frequency of reading. But when I will call the method to read from the "Execute" function of the thread, the method called will be located inside the second form in a specific class (but the method is not located in a visual component of the FMX library). So my questions are: Should I use "Synchronize" even if the method called is not a visual component ? I'm afraid of the fact that it could slow down the application as before by the timers if each thread is all the time Synchronizing to make the different read methods calls! To replace the 2 timers of the main thread, I imagined the use of 2 more threads to send events to the main form to let it know when it is needed to change of frame or going in standby mode. Is there a good idea? Is there really the good approach? I'm a little bit lost never stopping to think to do it in the better way. Many thanks to all in advance for your contributions.

I want to rotate a TLine(Shape group) but not all the shape, I want to rotate only the top, so to looks like a niddle swing right and left, I'm using Tanimate as well. Any help please 🙏

Hello members! I started learning delphi few months ago and recently i discovered that we can make really beautiful user interfaces with delphi FMX styles. I saw on the internet this animation demo ( This is just a design ) and I wanted to implement it in delphi: https://thumbs.gfycat.com/ShamelessConfusedAmbushbug-mobile.mp4 I was thinking to use ListView component in FMX for this with ItemApperance -> DynamicApperance. Everything was cool but i faced one problem. Problem is that I am not sure that TlistViewItem can perform animation when it is been added to the ListView. From my understandings i can only animate "Text1" and other items if i add them -> https://i.imgur.com/Y3SWIsT.jpg There is no option ( or I dont know how to find it ) To animate whole TListItemView when is added to a ListView. **WORKAROUND THAT I HAVE ON MY MIND** I was thinking to drop a ListBox and to add on it "TListBoxItem", after that i would right click it and Go on edit custom style, and try to make it look as i want. I tested this tutorial for editing the look of "TListBoxItem" and it is working nicely: https://www.experts-exchange.com/articles/10054/Implementing-a-ListView-in-Firemonkey.html For animation i planned to use this resources ( not tested, i dont know if it will work ) : So what is my question actually, well i would like to achieve similar design and effect from gif that i showed to you. I would like to use ListView with DynamicApperance. I would like to someone confirm me if that is possible and to give me some references or resource material where i could read more about it.. Also if there is someone who would like to give me a code example i would appreciate a lot. From my tests that i performed ( loop 1000 times, and add 1000 items on ListView and ListBox ) I can say that ListBox performed a lot slower so I would prefer ListView for this, also i think that using ListView here is better practice since ListView is more suitable for this situation based on this post: http://www.delphigroups.info/2/8f/544471.html At the end I just want to point out that im using FMX ONLY because i found it easier to make styles, this program is for Windows only platform. I am using Delphi Rio community ( Free version ). I would also like to add that option " Pull to refresh " that you see on that gif is not needed. Thank you for your answers and help! 🙂
