setX(x) - Sets the x-coordinate of the topleft corner of the image to the coordinate specified by the word x.
setY(x) - Sets the y-coordinate of the topleft corner of the image to the coordinate specified by the word x.

META Refresh Tag

disappear() - Stops the META Refresh Tag URL from being launched.
forceHit() - META Refresh Tag will perform its "hit" method without user input. The "hit" method will invoke all href functions of the META Refresh Tag.
forceUpdate() - Forces the META Refresh Tag to call its trigger variable function immediately.
maskedValue(y) - Sends the intrinsic value associated with the META Refresh Tag to the calling widget. The calling object then uses that value, ANDed with the mask y, as its input. This method is only valid if the intrinsic value is a byte or word. The mask y can be either a byte or word. This allows a Control object to provide the input to a View Widget. This method is called from a View Widget href.
reappear() - Allows the META Refresh Tag URL to be launched. Counteracts the disappear() method.
reset() - Resets timers in the META Refresh Tag.
setValue(x) - The META Refresh Tag intrinsic value is changed to x.
setMethod(m) - Changes the method originally specified by the META Refresh Tag's URL parameter; it is only valid when the originally specified method is a single function. If the URL method uses the UART, then you must use the setUARTMethod() method.
setOnVarMethod(m) - Changes the method originally specified by the META Refresh Tag's trigger variable parameter; it is only valid when the originally specified method is a single function. If the ONVAR method uses the UART, then you must use the setOnVarUARTMethod() method.
setOnVarUARTMethod(m) - Changes the UART method originally specified by the META Refresh Tag's trigger variable parameter; it is only valid when the originally specified method is a single function. If the ONVAR method does not use the UART, then you must use the setOnVARMethod() method.
setOnVarVariableNumber(x) - Changes the variable number originally specified by the META Refresh's onVar parameter. Can be used only if the META Refresh onVar has a byte(y), word(y) or string(y). In all cases, the y gets changed to the argument specified in setOnVarVariableNumber(x).
setTrigger(x) - Changes the trigger value originally specified by the META Refresh's trigger, trigger.gt or trigger.lt parameter to the byte value x.
setUARTMethod(m) - Changes the UART method originally specified by the META Refresh Tag's URL parameter; it is only valid when the originally specified method is a single function. If the URL method does not use the UART, then you must use the setMethod() method.
setUpdateRate(f) - Changes the update rate originally specified by the META Refresh Tag, the argument being a floating point number, specifying time in seconds.
setVariableNumber(x) - Changes the variable number originally specified by the META Refresh's URL parameter. Can be used only if the META Refresh URL has a byte(y), word(y) or string(y). In all cases, the y gets changed to the argument specified in setVariableNumber(x); it is only valid when the originally specified method is a single function.
value() - Sends the intrinsic value associated with the META Refresh Tag to the calling widget. The calling object then uses that value as its input. This allows a Control object to provide the input to a View Widget. This method is called from a View Widget href.

Regarding Method Parameters

Regarding x - For Control Widgets that have intrinsic values, such as lists and sliders, leave the argument field empty, since the intrinsic value of the selection will be sent out. Anchors, META Refresh Tags, Area Maps and Function/Custom Buttons should use x. The range for x is 0-255 (0x00-0xff) for a BYTE, 0-65535 (0x00-0xffff) for a WORD and strings in double quotes for STRINGs.
Regarding m - When setMethod(),setOnVarMethod(),setOnVarUARTMethod() or setUARTMethod(), is the IWC method, the argument should be the name of the method you want to set. i.e. disappear() or byte.value(). Notice when dealing with a method that relies on a type (byte, word or string) you need to include the type separated by a dot and then the method (i.e. word.value()) instead of just the method by itself.
Regarding f - For Control Widgets that have intrinsic values, such as lists and sliders, leave the argument field empty, since the intrinsic value of the selection will be sent out. Anchors, META Refresh Tags, Area Maps and Function/Custom Buttons should use f. Like the regular updateRate, use the floating point number to specify the update rate in seconds. The range for f is 0-655.35.
