Root Properties

Not used by the Root object.

Not used by the Root object.

Handle of current callback's object. This property contains the handle of the object whose callback routine is currently executing. If no callback routines are executing, this property contains the empty matrix [ ]. See also the gco command.

This property has been superseded by the getframe command.

This property has been superseded by the getframe command.

Handles of child objects. A vector containing the handles of all nonhidden Figure objects. You can change the order of the handles and thereby change the stacking order of the Figures on the display.

Clipping has no effect on the Root object.

The Root does not use this property.

Handle of the current Figure window, which is the one most recently created, clicked in, or made current with the statement:

figure(h)

set(0,'CurrentFigure',h)

get(0,'CurrentFigure')

This property is not used since you cannot delete the Root object

Diary file mode. When this property is on, MATLAB maintains a file (whose name is specified by the DiaryFile property) that saves a copy of all keyboard input and most of the resulting output. See also the diary command.

Diary filename. The name of the diary file. The default name is diary.

Script echoing mode. When Echo is on, MATLAB displays each line of a script file as it executes. See also the echo command.

Text of last error message. This property contains the last error message issued by MATLAB.

Output format mode. This property sets the format used to display numbers. See also the format command.

• short - Fixed-point format with 5 digits.
• shortE - Floating-point format with 5 digits.
• shortG - Fixed- or floating-point format displaying as many significant figures as possible with 5 digits.
• long - Scaled fixed-point format with 15 digits.
• longE - Floating-point format with 15 digits.
• longG - Fixed- or floating-point format displaying as many significant figures as possible with 15 digits.
• bank - Fixed-format of dollars and cents.
• hex - Hexadecimal format.
• + - Displays + and - symbols.
• rat - Approximation by ratio of small integers.

Output format spacing (see also format command).

• compact -- Suppress extra line feeds for more compact display.
• loose -- Display extra line feeds for a more readable display.

System environment setting.

Handle of parent object. This property always contains the empty matrix, as the Root object has no parent.

Current location of pointer. A vector containing the x- and y-coordinates of the pointer position, measured from the lower-left corner of the screen. You can move the pointer by changing the values of this property. The Units property determines the units of this measurement.

Handle of window containing the pointer. MATLAB sets this property to the handle of the Figure window containing the pointer. If the pointer is not in a MATLAB window, the value of this property is 0. A callback routine querying the PointerWindow can get the wrong window handle if you move the pointer to another window before the callback executes. This error results from delays in callback execution caused by competition for system resources.

M-file profiler on or off. Setting this property to on activates the profiler when you execute the M-files named in ProfileFile. The profiler determines what percentage of time MATLAB spends executing each line of the M-file. See also the profile command.

M-file to profile. Set this property to the full path name of the M-file to profile.

Profiler output. This property is a n-by-1 vector, where n is the number of lines of code in the profiled M-file. Each element in this vector represents the number of times the profiler found MATLAB executing a particular line of code. The ProfileInterval property determines how often MATLAB profiles (i.e., determines which line is executing).

Time increment to profile M-file. This property sets the time interval at which the profiler checks to see what line in the M-file is executing.

Number of nested M-file calls. This property sets a limit to the number of nested calls to M-files MATLAB will make before stoping (or potentially running out of memory). By default the value is set to a large value. Setting this property to a smaller value (something like 150, for example) should prevent MATLAB from running out of memory and will instead cause MATLAB to issue an error when the limit is reached.

Screen depth. The depth of the display bitmap (i.e., the number of bits per pixel). The maximum number of simultaneously displayed colors on the current graphics device is 2 raised to this power.

Screen size. A four-element vector,

[left,bottom,width,height]

This property has no effect on the Root level.

This property has no effect on the Root level.

Show or hide handles marked as hidden. When set to on, this property disables handle hiding and exposes all object handles, regardless of the setting of an object's HandleVisibility property. When set to off, all objects so marked remain hidden within the graphics hierarchy.

User-specified object label. The Tag property provides a means to identify graphics objects with a user-specified label. While it is not necessary to identify the Root object with a tag (since its handle is always 0), you can use this property to store any string value which you can later retrieve using set.

Hide graph window command. This property specifies the escape sequence that MATLAB issues to hide the graph window when switching from graph mode back to command mode. This property is used only by the terminal graphics driver. Consult your terminal manual for the correct escape sequence.

One window terminal. This property indicates whether there is only one window on your terminal. If the terminal uses only one window, MATLAB waits for you to press a key before it switches from graphics mode back to command mode. This property is used only by the terminal graphics driver.

Size of default terminal. This property defines the size of the terminal.

Type of terminal. This property tells MATLAB what type of terminal you are using. Specify tek401x for terminals that emulate Tektronix 4010/4014 terminals. Specify tek410x for terminals that emulate Tektronix 4100/4105 terminals. If you are using X Windows and MATLAB can connect to your X display server, this property is automatically set to x.

Display graph window command. This property specifies the escape sequence that MATLAB issues to display the graph window when switching from command mode to graph mode. This property is only used by the terminal graphics driver. Consult your terminal manual for the appropriate escape sequence.

Class of graphics object. For the Root object, Type is always 'root'.

This property has no effect on the Root level.

Unit of measurement. This property specifies the units MATLAB uses to interpret size and location data. All units are measured from the lower-left corner of the screen. Normalized units map the lower-left corner of the screen to (0,0) and the upper right corner to (1.0,1.0). inches, centimeters, and points are absolute units (one point equals 1/72 of an inch).

User specified data. This property can be any data you want to associate with the Root object. MATLAB does not use this property, but you can access it using the set and get functions.

Object visibility. This property has no effect on the Root object.
