h.delete
delete(h)
h.delete releases all interfaces derived from the specified COM server or control, and then deletes the server or control itself. This is different from releasing an interface, which releases and invalidates only that interface.
delete(h) is an alternate syntax.
COM functions are available on Microsoft Windows systems only.
Create a Microsoft Calendar application. Then create a TitleFont interface and use it to change the appearance of the font of the calendar's title:
f = figure('position',[300 300 500 500]);
cal = actxcontrol('mscal.calendar', [0 0 500 500], f);
TFont = cal.TitleFont
MATLAB software displays information similar to:
TFont = Interface.Microsoft_Forms_2.0_Object_Library.Font
Make the following changes and observe the results:
TFont.Name = 'Viva BoldExtraExtended'; TFont.Bold = 0;
When you're finished working with the title font, release the TitleFont interface:
TFont.release;
Now create a GridFont interface and use it to modify the size of the calendar's date numerals:
GFont = cal.GridFont
MATLAB displays:
GFont = Interface.Microsoft_Forms_2.0_Object_Library.Font
Make the following changes and observe the results:
GFont.Size = 16;
When you're done, delete the cal object and the figure window. Deleting the cal object also releases all interfaces to the object (for example, GFont):
cal.delete; delete(f); clear f;
Note that, although the object and interfaces themselves have been destroyed, the variables assigned to them still reside in the MATLAB workspace until you remove them with clear:
whos
MATLAB displays (in part):
Name Size Bytes Class GFont 1x1 0 handle TFont 1x1 0 handle cal 1x1 0 handle
release, save (COM), load (COM), actxcontrol, actxserver
