TFrameInfo / TFormInfo

TSubjectInfo = class                              // unit SubjectStand
TFrameInfo<T: TFrame> = class(TSubjectInfo)       // unit FrameStand
TFormInfo<T: TForm>   = class(TSubjectInfo)       // unit FormStand

The info is the handle of one subject on its stand. It is created by New/Use and freed by Close.

Properties

Property	Type	Description
Frame	T	The frame (TFrameInfo<T>).
FrameIsOwned	Boolean	When True, Close frees the frame. True after New, False after Use.
FrameStand	TFrameStand	The component.
Form, FormIsOwned, FormStand		The same for TFormInfo<T>.
FormContainer	TLayout	The layout holding the controls moved from the form (TFormInfo<T>).
Subject	TSubject (TFmxObject)	The subject, untyped.
SubjectIsOwned	Boolean	Untyped alias of FrameIsOwned / FormIsOwned.
SubjectStand	TSubjectStand	The component, untyped.
Stand	TControl	The clone of the stand.
StandStyleName	string	Name of the stand used.
Container	TFmxObject	Element of the stand holding the subject.
Parent	TFmxObject	Object holding the stand.
Status	TSubjectStatus	Initializing, Ready, Showing, Visible, Hiding, Hidden, Closing.
IsVisible	Boolean	Stand.Visible.
Hiding	Boolean	A Hide is in progress.
IsModal	Boolean	Shown with ShowModal and waiting for its result.
BackKeyAction	TBackKeyAction	What Back and Esc do to this subject when it is on top and is not a dialog: baNone (default), baHide, baHideAndClose, baPop (set by Push on the pages above the root). See Back and Esc.
ModalResult	TModalResult	The result of a subject shown with ShowModal: setting a value other than mrNone hides it, calls the result procedure and closes it (unless AClose = False). The first result wins. On other subjects it is only stored. See Dialog Results.

Methods

Method	Description
Show	Shows the subject: [BeforeShow], OnBeforeShow, [Show] or default show, show animations, [AfterShow], OnAfterShow.
Hide(ADelay = 0; AThen = nil): Boolean	Starts the hide animations and hides after the longest of them (or after ADelay ms, if not 0); then calls AThen and OnAfterHide. Returns False if a hide is already in progress: no new hide starts, and AThen is called when the current one completes.
HideAndClose(ADeferExecutionMS = 0; AThen = nil)	Hide, then waits DefaultHideAndCloseDeferTimeMS (or ADeferExecutionMS), then Close and AThen. Calls made while a hide or a hide-and-close is in progress close the subject once, when it completes, and call every AThen.
Close	Removes the subject, without animations: frees the stand, frees or detaches the subject, frees the info.
ShowModal(AResultProc; AClose = True)	Shows the subject as a dialog. AResultProc is a TProc<TModalResult>, or a TProc<T, TModalResult> that receives the frame (TFrameInfo<T>) or the form (TFormInfo<T>) too. It is called once, after the hide animation and before the close, with ModalResult or mrCancel. With AClose = False the subject is only hidden. See Dialog Results.
HideAndCloseAfter(ADelayMS)	HideAndClose after ADelayMS milliseconds (a snackbar); nothing happens if the subject is closed before.
StopAnimations	Stops all the show and hide animations of the stand.
DefaultShow / DefaultHide	The default show and hide, useful from your [Show] / [Hide] methods.
Show(ABackgroundTask, AOnTaskComplete, AOnTaskCompleteSynchronized): ITask	Deprecated. See Background Work.
