Sparta Docked Form Editor and Qt5
« on: January 20, 2018, 07:37:09 pm »
Has anyone else been able to successfully use the Sparta Docked Form Editor under Qt5? I've tried with Lazarus 1.8 and 1.9 (trunk, today), and every time I add the docked form editor and load an application with a form, Lazarus freezes, then crashes.

If I uninstall the docked form editor package, then everything works fine.

My system is runnign Ubuntu 17.10 x86_64. Unfortunately, I'm trying to rebuild the Qt5 version again using fpcupdeluxe, and even after cleaning up all of the files from a previous build, I'm getting an "Got an unexpected exception ... don't know what to do unfortunately." error message when trying to build fpc and lazarus trunk. I'm sort of new at working with bleeding edge fpc / lazarus.

Follow-up. Was able to build fpc and lazarus trunk again by building them separately (building them at the same time seemed to cause an exception somewhere with fpcupdeluxe). After applying the patch your referenced, the docked form designer no longer crashes lazarus on execution. I'll test it some more in the next few days.

Thanks much for the assistance!
