How do I modify theme of an object, that is added with function OpenUserObject(), like this:

uo_StaticText luo_StaticText
THIS.OpenUserObject(luo_StaticText, 270, 380)

 

I've made a custom theme-custom.json file in my theme folder, it looks something like this:

{
"meta-info":
{
"version":"190"
},
"w_themestest_main$statictext":
{
"drawing":false
},
"w_themestest_main$userobject":
{
"drawing":false
}
}

It does disable theme for objects that are added via IDE, but I can't figure out how to modify object added with OpenUserObject().

Please see attached sample project.

I also tried "w_themestest_main$uo_statictext" and "uo_statictext", does not work either...

Any ideas?

Hi Valdis;

  Unfortunately, that is theme feature is not supported as even when you create an over-riding theme extension, the object name and it's parent have to be known before the Theme is enabled. In your case, the OpenUserObject() is using a dynamic pointer. However, it even gets worse as you progress into a full dynamic class name user object instantiation, for example:

  • DragObject lo_open
  • string       ls_name
  • ls_name = sle_user.Text
  • THIS.OpenUserObject (lo_open, ls_name, 100, 200)

  In both cases, this would (AFAIK) require an enhancement to the PBVM (runtime) as say something like for example a new Theme.Refresh() command that the PB App could call after a visible dynamic object(s) are created (ie OpenUserObject, OpenTabPage, etc).

Regards ... Chris

But if I modify main theme.json file and set "statictext":{"drawing":false} then it works, why override theme extension does not?

Yes, that would work as it affects *any* class of type "static text" regardless of the current instantiated name.
