About

ATFlatToolbar is component which creates row of ATButton's on it, this looks like toolbar.

It don't support creating toolbar in IDE design time. You need to call methods:

AddButton: to add usual button (with caption or not)
AddDropdown: to add button with attached drop-down menu
AddChoice: to add button which acts like a combobox, with Items and ItemIndex
AddSep: to add button which looks like "|" separator line
UpdateControls: this updates buttons placement, you must call it after changes (also after ImageList size is changed)

Use props ButtonCount and Buttons[i] to get ATButton's from component.
Use Buttons[i].Free to delete buttons.
To make vertical toolbar, set prop KindVertucal to True. In the vertical mode, don't add buttons of kind "dropdown arrow only", they won't paint ok, and it makes no sence.
