I am not sure if what you are looking for is like TButtonEdit in LCL. It 
anchors a TSpeedButton to the TEdit. It is not the ideal solution, but 
it works. Some of the disadvantages are:

- The need for glue code that handles anchoring, freeing, visibility, 
readonly, etc...
- The width/height of the component are those of the TEdit itself
- The needed button's events must be explicitly exposed

Maybe a special component anchor control can be devised to provide the 
functionality?
