Reimplemented from TObject.

Reimplemented in TSystemDirectory.

Definition at line 69 of file TSystemFile.cxx.

◆ Copy() [1/2]

inlinevirtual

Delete this object.

Typically called as a command via the interpreter. Normally use "delete" operator when object has been allocated on the heap.

Reimplemented from TObject.

Definition at line 57 of file TSystemFile.h.

◆ DrawClass()

void TSystemFile::DrawClass ( ) const

inlinevirtual

Draw class inheritance tree of the class to which this object belongs.

If a class B inherits from a class A, description of B is drawn on the right side of description of A. Member functions overridden by B are shown in class A with a blue line crossing-out the corresponding member function. The following picture is the class inheritance tree of class TPaveLabel:

TObject * TSystemFile::DrawClone ( Option_t * option ) const

inlinevirtual

Draw a clone of this object in the current selected pad for instance with: gROOT->SetSelectedPad(gPad).

virtual

dump this file

Reimplemented from TObject.

◆ Edit()

void TSystemFile::Edit ( )

Invoke text editor on this file.

Reimplemented in TSystemDirectory.

Definition at line 78 of file TSystemFile.cxx.

◆ GetIconName()

const char * TSystemFile::GetIconName ( ) const

inlinevirtual

Returns mime type name of object.

Used by the TBrowser (via TGMimeTypes class). Override for class of which you would like to have different icons for objects of the same class.

Reimplemented from TObject.

Definition at line 46 of file TSystemFile.h.

◆ Inspect()

void TSystemFile::Inspect ( ) const

virtual

inspect this file

Reimplemented from TObject.

virtual

move this file

Reimplemented in TSystemDirectory.

Definition at line 125 of file TSystemFile.cxx.

virtual

rename this file

Definition at line 162 of file TSystemFile.cxx.

◆ SetDrawOption()

void TSystemFile::SetDrawOption ( Option_t * option )

inlinevirtual

Set drawing option for object.

This option only affects the drawing style and is stored in the option field of the TObjOptLink supporting a TPad's primitive list (TList). Note that it does not make sense to call object.SetDrawOption(option) before having called object.Draw().

Reimplemented from TObject.

Definition at line 54 of file TSystemFile.h.

void TSystemFile::SetName ( const char * name )

inlinevirtual

Set the name of the TNamed.

WARNING: if the object is a member of a THashTable or THashList container the container must be Rehash()'ed after SetName(). For example the list of objects in the current directory is a THashList.

Reimplemented from TNamed.

Definition at line 55 of file TSystemFile.h.

◆ SetTitle()

void TSystemFile::SetTitle ( const char * title )

inlinevirtual

Set the title of the TNamed.
