Mix builds?

Hi - is it possible to use both the Lite and Pro version at the same time? I'm working in Rad Studio 10.3 (Rio) and i'm trying to avoid the memory leak that is still present (introduced at v2017.22 - http://bugs.teechart.net/show_bug.cgi?id=2243). The Lite version that ships with Rad Studio covers 9...

Re: memory leak on iOS with teechart (FMX, C++)

By modifying the "19.0" key as here: https://www.steema.com/support/viewtopic.php?t=17086&start=15, i was able to run the installer without any errors. However, i still just have the "TeeChart Lite FMX Components", no Pro. So, looks like still need help installing this older Pro build for use with R...

Re: memory leak on iOS with teechart (FMX, C++)

Hi Yeray, I just now purchased the Pro version so i can create polar plots. I downloaded that older version (v2017.21) to avoid this memory leak. When i install i get an error message, "TeeChart files to AUTO install cannot be found." I click OK and it finishes, but i don't get the Pro features in R...

Re: memory leak on iOS with teechart (FMX, C++)

Hi Yeray,

Did you have a chance to try building and testing with v2016.17.160129 to see if it runs without memory leak?

thank you,
russ

Re: memory leak on iOS with teechart (FMX, C++)

Ok, this looks like a memory leak bug introduced sometime AFTER TeeChart Standard version v2016.17.160129. This is the lite version that comes free with Rad Studio 10.3.2. I uninstalled my licensed copy of TeeChart Standard VCL/FMX released May 30, 2019 - Build 2019.27.190530. Then, uninstalled/rein...

Re: memory leak on iOS with teechart (FMX, C++)

I've tested and the memory leak is not in ScrollBox, it is in the TChart. In the attached project (zip) i simply added a timer that moves the TChart up and down every 0.1 seconds. After 2-3 minutes it crashes on memory error on iOS with no user input after clicking Button1. On Win32 memory is stable...

Re: Access violations C++ Builder Rio and Android

Hi Yeray, I've spent the day on a memory leak error (the minor Android issues i'll get back to). I can create one or more TeeChart's on a TScrollBox in my FMX app (i have a nice template chart that i just clone and add series to). It works fine - except, if i start scrolling up/down or left/right to...

Re: Access violations C++ Builder Rio and Android

Hi Marc, Sorry, just now saw your reply. No, the simple code above caused the access violation. In fact, I've had quite a few problems - including one now that i can't figure how to stop. After i've created several charts - the app will spontaneously crash. I'm putting the charts in a TScrollBox so ...

Access violations C++ Builder Rio and Android

Hi, I have a resize function that adjusts chart height/width and position on form, it works fine. Today i tried to add ability to toggle bottom axis labels on/off. ChartName->BottomAxis->Labels = true; (or = false) causes an access violation on Android. Works fine on iOS. Is this a known bug? The on...
