@davidking, can you be more specific about where exactly "Compiler Defines" is located. I'm using Codesys v3.5 SP21 Patch2 and cannot find this Compiler Defines option. In the menu Project -> Project Settings there are Compiler options and Compiler warnings, but that is not it.

Hello Tim, I am using CODESYS Visu V4.8.1.0. It works when I turn off the "Support client animation and overlay of native elements". But if I do that, dialog box moving and other options are also disabled so it is a bit problematic. Thank you for helping.

Post by dekelec on TrueType font problem ^{CODESYS Forge talk (Post)}
Initially I had the same problem in CoDeSys when selecting a newly installed TTF font, while CoDeSys was running. I solved it by closing Codesys and running it again to restart the initialization process. After that, using the new font did not pop up errors. I also had cases with files that had a ttf extension, but were actually not TrueType.

Post by beavel on Customizing FileOpenSave Dialog and Keypad Integration in Visualization ^{CODESYS Forge talk (Post)}
Hi all, I'm looking to adjust the visualization of the FileOpenSave dialog. Is there a library or visualization file associated with this dialog that can be extracted, customized, and re-imported into the project — similar to how the user management dialogs can be handled? Alternatively, is there a supported way to replace or override the default dialog with a custom one? Also, is it possible to configure the FileOpenSave dialog to use a custom keypad for text input? The rest of the project uses a custom keypad due to readability concerns (the default one is too small), and this inconsistency is now quite noticeable. Any guidance or workarounds would be greatly appreciated. Thanks in advance! @thk @eschwellinger @sheberle

I have found a work around. I have written a python scripts that runs on user login (entry in .bashrc) which overwrites the webvisu.htm and webvisu.cfg.json file with the configuration for the B&R T30 panel (resolution and disable scaling). First I tried to add this setting to the the CODESYSControl.cfg, but that does not work following the big CODESYS Control V3 Manual.

Post by micik on PLCOpenXML Export/Import with Visualisation ^{CODESYS Forge talk (Post)}
I have noticed that Codesys doesn't provide option to Export any Visualization objects even though there is option to check to export VISU_TASK, which is strange because when Import in another empty project, user will end up with build errors. I understand that probable reason for this is that PLCOpenXML specification includes only "PLC" parts of the project (POU, PRG, variable lists, device ....), but not sure about it. Perhaps, there is some option to include visu objects also in the plcopen xml export list??

Post by nathant on Some visualization objects disappear when user is logged in? ^{CODESYS Forge talk (Post)}
I am deploying a webvisu on Codesys 3.5 SP 19.2 with legacy user management. I noticed that when a user logs in, some text and a rectangle I have (for aesthetics) both disappear. I made sure that none of the objects in question are linked to a state variable. Anyone know the cause/solution to this? Nothing crucial to the machine's function is lost, but it is a little annoying.

Post by thomasrohnerch on Color Change for Symbols not working ^{CODESYS Forge talk (Post)}
I have some Symbols from the Visualization Toolbox on my Target Visu on the Computer. I tried many Symbols, mainly Arrows. I'm able to control the visibility with condition e.g. "GVL.actual_testvalues.speed <= 0" But I can't do "Toggle color" with boolean GVL.b_toggle_color. Neither "TRUE" nor "FALSE" does change anything. Is this a known issue? I'm using CODESYS V3.5 SP19 Patch 5 + (64-bit). See attached file with more Version-Info. I'm currently using Style 6, Gradient axial 2, 3.5.12.0. I had the same issue with Default 3.5.16.0.

When I run the soft PLC the my visualization screen appears full screen, I would like to be able to set the size of the visualization screen so I can display other software on the monitor. Is it possible to set the width/height of the targetVisu? Anyone try something similar? I would like to avoid having to put it on a Virtual Machine. Thank you

Post by taywinkel on Virtual Keyboard Support on Login Page ^{CODESYS Forge talk (Post)}
I am in the process of getting a visualization to work with the codesys keyboard. I created a custom keyboard which works fantastic for all input fields in the main visualization. I created a user management for my runtime, which gave me the standard blue login page. The codesys keyboard does not show up when trying to enter the usernam or password. I have tried every setting: changing the keyboard back to the standard codesys keyboard, and changing various settings on the visualization manager with no success. I can only use a physical keyboard connected to the device to enter the password. I did try removing the keyboard to no success either. I even tried creating my own login page so I could guarantee the keyboard showed up. This ended in disaster as I could not figure out the very complicated VisuUserManagement and VisuUserManagementDialog library, and documentation is contradictory or lacking. I imagine that an on screen keyboard is essential for many people's projects when using touchscreen panels, so I am wondering what others are doing. I would rather not use an external virtual keyboard (external to codesys) because this causes its own complications (I am working on a linux build with high securities).
