25 // A TGDockableFrame is a frame with handles that allow it to be //
26 // undocked (i.e. put in a transient frame of its own) and to be docked //
27 // again or hidden and shown again. It uses the TGDockButton, which is //
28 // a button with two vertical bars (||) and TGDockHideButton, which is //
29 // a button with a small triangle. The TGUndockedFrame is a transient //
30 // frame that on closure will put the frame back in the dock. //
