4.2.1.10

showSubMenu

The

gui.showSubMenu

method instructs the OHV300 to display the specified menu on

the OHV300 display as a standard

gui

object (section 4.2.3).

Format:

gui.showSubMenu(yourMenu, parentMenu);

Where:

yourMenu

– menu object to show on the display. The object must be a

gui.Menu

object

(section 4.2.3.6).

parentMenu

– parent menu to display in response to

gui.backSoftkey

Note: This method does not return a value.

To insert a caption into the status bar, set the

yourMenu.caption

property.

This method sets the left software programmable key to

gui.selectSoftkey

(section

4.2.4.4).

This method sets the right software programmable key to

gui.backSoftkey

(section

4.2.4.1) and sets the menu object’s

onCancel

property to a function that shows the parent

menu.

4.2.1.11

splash and clearSplash

The

gui.splash

method displays an image on the OHV300 screen. The

gui.splash

function should be used in conjunction with the

setTimeout

function. The

setTimeout

function will suspend execution for a provided timeout value. Once the timeout specified in
the

setTimeout

function expires, it will call the function specified in the

setTimeout

continue execution.

Format:

gui.splash(imageName, stringText);

setTimeout(func, timeout_ms);

Where:

imageName

– string; the name of the image file to display (section 4.2.3.4).

stringText – string; the text string to be displayed below the image in the softkey area of the
display.

func

– function; the name of the function to be called after timeout.

timeout_ms

– number; the number of milliseconds to wait before timeout of the splash

display.
