Where to find information about Structure Attributes?

Targets Windows
1

Hello,

I use many declares in my programs, and there are times when I like/need to use attributes of a structure, such as StructureAlignment. Are there more undocumented features that were described in the post: structure-alignment ?

When I right-mouse-click on the Attributes line, the options that appear are:
DefaultEvent
Deprecated
Hidden
HideFromLibrary
StructureAlignment

I have used the undocumented padding structure underscore for conversion of C++ structures to C structures. Are there any other bits and pieces of information about Xojo Structure Attributes available? I have looked and may have missed it, and is there a link that might have more information from Xojo about these Attributes?

Thanks!

Advanced OOP features — Xojo documentation about 3/4 the way down under Special Attributes

I too use the undocumented _ “feature” to hide padding entries and never use StructureAlignment but prefer to pad them manually due to <https://xojo.com/issue/48449> and <https://xojo.com/issue/51124> after manually checking the size and padding in VS for both 32 and 64bit.

Thank you Julian,

I am glad that there is some documentation on it, and thanks for pointing me in the right direction.

Warm regards.
