NAME

       ImportCmd - import a graphical component

SYNOPSIS

       #include <Unidraw/Commands/import.h>

DESCRIPTION

       ImportCmd  imports a graphical image from a file into the drawing being edited.	ImportCmd supports the following file formats: TIFF; Post-
       Script generated by pgmtops and ppmtops; X bitmap format; and Unidraw format.

PUBLIC OPERATIONS

       ImportCmd(ControlInfo*, FileChooser* = nil)
       ImportCmd(Editor* = nil, FileChooser* = nil)
	      Create a new ImportCmd instance, optionally supplying the FileChooser that will prompt the user  to  specify  the  file  to  import.
	      After  the user specifies the file, ImportCmd reads it, creates an appropriate graphical component, and pastes it into the component
	      being edited in the enclosing editor.

       static GraphicComp* Import(const char*)
       static GraphicComp* TIFF_Image(const char*)
       static GraphicComp* PGM_Image(const char*)
       static GraphicComp* PPM_Image(const char*)
       static GraphicComp* XBitmap_Image(const char*)
	      Operations for reading data from various file formats and creating  an  appropriate  graphical  component.   TIFF_Image,	PGM_Image,
	      PPM_Image,  and  XBitmap_Image assume that the specified file is in the corresponding format.  Import is more general: it determines
	      the format from the file and then calls one of the other functions.

PROTECTED OPERATIONS

       void Init(FileChooser*)
	      Specify the FileChooser instance (stored in the _dialog protected member) explicitly.  This operation does not delete  the  existing
	      instance, if any.

       GraphicComp* PostDialog()
	      Post the FileChooser and return the graphical component created from the user-specified file, if any.

NAME

       BackCmd, FrontCmd, GroupCmd, UngroupCmd - commands for modifying components structurally

SYNOPSIS

       #include <Unidraw/Commands/struct.h>

DESCRIPTION

       BackCmd,  FrontCmd,  GroupCmd, and UngroupCmd are purely interpretive commands for altering the structure of their editor's component.  All
       redefine their Execute and Unexecute operations to let the editor's component interpret them as it wishes.

BACKCMD PUBLIC OPERATIONS

       BackCmd(ControlInfo*)
       BackCmd(Editor* = nil)
	      Construct a new BackCmd.

FRONTCMD PUBLIC OPERATIONS

       FrontCmd(ControlInfo*)
       FrontCmd(Editor* = nil)
	      Construct a new FrontCmd.

GROUPCMD PUBLIC OPERATIONS

       GroupCmd(ControlInfo*, GraphicComp* = nil)
       GroupCmd(Editor* = nil, GraphicComp* = nil)
	      Create a new GroupCmd, optionally specifying the component into which components will be grouped.

       virtual void Execute()
       virtual void Unexecute()
	      Execute will set the value of the _executed protected member variable to true as a side effect if anything was grouped.	Similarly,
	      Unexecute will set reset the value to false as a side effect the operation was undone.

       GraphicComp* GetGroup()
       void SetGroup(GraphicComp*)
	      Get or set the component into which components will be grouped.  SetGroup will not delete the old value.

UNGROUPCMD PUBLIC OPERATIONS

       UngroupCmd(ControlInfo*)
       UngroupCmd(Editor* = nil)
	      Construct a new UngroupCmd.

       virtual void Execute()
       virtual void Unexecute()
	      Execute  will  set  the  value of the _executed protected member variable to true as a side effect if anything was ungrouped.  Simi-
	      larly, Unexecute will set reset the value to false as a side effect the operation was undone.

       Clipboard* GetKids()
       void SetKids(Clipboard*)
	      Explicitly set and get a clipboard containing the child components that were ungrouped, which is stored in the _kids protected  mem-
	      ber.   UngroupCmd  does not initialize this member; it merely provides the storage as a convenience to components that interpret the
	      command and need a place to store the ungrouped children to support reverse execution.  However, UngroupCmd  deletes  the  clipboard
	      (if it exists) in ~UngroupCmd. SetKids will not delete the old value.
