Hi,

I use KDE4 and some desktop themes use focus rectangle and the others
don't. Has Lazarus some function or boolean property to detect whether
current desktop theme uses Focus Rectangle ? I need for my component -
to make its design uniform.

Thanks.

Sounds like a KDE-only feature. Lazarus or LCL don't have it. You
could try to connect to KDE API directly somehow but I don't know how.
This is a typical problem with cross-platform GUI libraries. You only
get a subset of of each target platform.

Juha, do you mean that all themes on all other (Win, GTK2 & Carbon)
widgetsets have always Focus Rectange painted ?

You don't need to know if it "uses" Focus Rectangle or not, you should
send paint via Themes, so theme will paint it or not. It's easy with
qt but don't know for others. Do you use LCLIntf.DrawFocusRect() or
something else ?

How can I send paint via Themes ? For  example I use ThemeServices for
painting button, highlighted button and so. I can use
LCLIntf.DrawFocusRect() or Canvas.DrawFocusRect() and both draw
FocusRect anyway (even if theme does not draw it).
