how to set focus (to an editor) ?

hello,

I'm using a Scintilla editor to show the active code in a simulation.
Now I'm not familiar with Scintilla at all,
and as for the moment I use just a few options of Scintilla,
and the manual is so huge ...
... I can't find a method to keep focus on the editor.

So in general is there a command to set focus to a visual component ?

And specific for Scintilla,
I use these settings
   Code_Editor.SetCaretLineBack("BLUE")
   Code_Editor.SetCaretLineVisible(True)
   Code_Editor.GotoLine(Active_LineNumber)
and as long as the editor (and application) has focus, the active line is nicely highlighted.
From Delphi I'm used, that most components can keep the active highligting, even when object / application looses focus,
by setting a special flag of that component.
But I can't find such a flag within Scintilla.
I've tried
      STCFocus(True)
      GetSTCFocus()
but both of them crashes.
Anyone has a good idea ?

cheers,

Does it crash or just give an exception? Using SetSTCFocus seems to be working for me. Combining that with some handlers for EVT_KILL_FOCUS and EVT_SET_FOCUS should do the trick.

You can also specify a marker that instead of drawing a symbol in the margin does a line highlight. You could then use that to highlight lines, once the marker has been set for a line it will stay there regardless of focus until you remove it.

Thanks Robin,

SetSTCFocus works (I used STCFocus),
dont know the difference, but that's of no importance at this moment.

One is a function and one is a property.
