Is there a way to add some buttons to the selected ListBoxItem by adding these buttons to a style which is being used for the selected item?
I didn't yet find a suitable style FMX uses to display the selected item.
My goal is to have some buttons on the selected item with context based functionality. While I can do this by reparenting a TButton created in code in the OnPaint event of the ListBox, this works for Android but not for Win32 as it is being overpainted by the selection.
Other solutions like doing this in OnItemClick or OnClick are sluggish or only work properly on Win32 but not on Android and would need to be put into a timer fired on click.
