Text PropertiesNote that setting the root FixedWidthFontName property causes an immediateupdate of the display to use the new font.FontSizesize in FontUnitsFont size. An integer specifying the font size to use for text, in units determinedby the FontUnits property. The default point size is 10 (1 point = 1/72 inch).FontWeightlight | {normal} | demi | boldWeight of text characters. MATLAB uses this property to select a font fromthose available on your particular system. Generally, setting this property tobold or demi causes MATLAB to use a bold font.FontUnits {points} | normalized | inches |centimeters | pixelsFont size units. MATLAB uses this property to determine the units used by theFontSize property. Normalized units interpret FontSize as a fraction of theheight of the parent axes. When you resize the axes, MATLAB modifies thescreen FontSize accordingly. pixels, inches, centimeters, and points areabsolute units (1 point = 1/72 inch).HandleVisibility{on} | callback | offControl access to object’s handle by command-line users and GUIs. Thisproperty determines when an object’s handle is visible in its parent’s list ofchildren. HandleVisibility is useful for preventing command-line users fromaccidentally drawing into or deleting a figure that contains only user interfacedevices (such as a dialog box).Handles are always visible when HandleVisibility is on.Setting HandleVisibility to callback causes handles to be visible fromwithin callback routines or functions invoked by callback routines, but not fromwithin functions invoked from the command line. This provides a means toprotect GUIs from command-line users, while allowing callback routines tohave complete access to object handles.Setting HandleVisibility to off makes handles invisible at all times. Thismay be necessary when a callback routine invokes a function that mightpotentially damage the GUI (such as evaluating a user-typed string), and sotemporarily hides its own handles during the execution of that function.2-514
