TouchScrolling not working on bitmaps

I could cast cell to TTMSFMXBitmapGridCell and use the Bitmap property to show bitmaps and set aligning etc. but when I enable TouchScrolling and hide both scrollbars, it seems scrolling only works when my finger is pressing on a no-bitmap-area in the cell, eg. text or blank area. if my finger is pressing on the bitmap and then want to scroll, nothing happens.

any settings missing to make this work?


The HitTest property for the bitmaps is set to true, which captures the mouse handling. Please additionally set HitTest to false on the bitmap property of type TTMSFMXBitmap to disable mouse event handling and allow touch scrolling.

Kind Regards, 

thx a lot, that really helped!
