8.6 Properties File Customization

Each screen in the PC NC MMI may have a properties file with which it is associ-

ated. This allows the screen to have modifiable properties without code changes.

Some examples are:

• fileManager.properties - defines directory choices in file manager drop

down.

• tempSensor.properties - defines limits for CPU temperature and fan speed.

• Button parameter screens, such as Offline Mode or Utilities: PC Settings

screens - each screen is a shared instance of the same screen object but with

different properties.

Environment Variables and Directories

Many items in the properties files use environment variables instead of

directory names. Environment variables are defined in the ‘applica-

tion.properties’ file. When a environment variable is referenced in another

properties file, is flanked by ‘%’ to indicate that is an environment vari-

able. For example, the following environment variable, MMIDATABASE,

is defined in the ‘application.properties’ file as follows:

MMIDATABASE = C:\\ypcnc\\database

Now other things may be defined using this macro. For example, if the help

file is ‘C:/ypcnc/database/help.text’, a properties file entry may be:

helpFile = %MMIDATABASE%\\help.text

Macros may be defined using other macros:

MMIDRIVE = C:

MMIROOT = %MMIDRIVE%\\ypcnc

MMIDATABASE = %MMIROOT%\\database

When defining subdirectories, note that ‘\\’, not ‘/’, is required between

subdirectory names.

Properties File Entries For Menus

Some properties files have entries that are used to specify what items are

shown in a drop-down menu on a particular screen. These files all use the

1 2 ... 281 282 283 284 285 286 287 288 289 290 291 ... 300 301
