SpkToolbar requires 24-bit Bitmaps
lazarus / 5-Lazarus Extra Components

When I compile and run the demo program that comes with SpkToolbar
exceptions are thrown in SpkGuiTools; the polish error message seems
to say that 24-bit bitmaps are required; when the exception occurs
TSpkToolbar.FBuffer is a 32bit-Bitmap. However, when I look at the
source this bitmap format is never generated. Does anybody have an
idea how to solve this?

I must have had a version mixup: after deleting my Lazarus profile the
SpkToolbar works fine again.

This is a nice component, but really slow the last time I've tested
it. I've tried with no results to do one with BGRABitmap, the complex
thing is not the graphics, for me is 'focusing' a group of components
and then focus one particulary (like in Office 2010). The rest
basically can be done with panels and buttons, and to skin the other
components with CustomDrawn for example.

So far I can live with the speed, maybe I should go to an older PC for
a more detailed test...

I have added checkboxes and radiobuttons to the component and fixed
some issues with the interaction with TAction. I will post the
component here once I'm finished with the design code, see the
attachment as an appetizer.

Does SpkToolbar support BiDiMode and RightToLeft drawing?

Very good! Waiting to see the final product.
