Digital Workshop

I have downloaded the free calculator from DW website and I have been trying to link the display number (a text object called DisplayString in the original calculator) to a page variable called price_right , by ticking the text input option “Allow user...” , so when I click a button if price_right is, let's say 55, it will add 1 to my score.

I have done this before with other text input objects, but with this from the calculator it doesn't work. Also by ticking the text input option, the format of the numbers displayed changes with shadow or flare.

I have attached an example in case someone have a solution without scripting.

It won't work because the text box doesn't contain a variable. It uses the replace string functionality to update the display and therefore making the text box editable will have no effect as Opus doesn't know that the value has changed.

Thanks Mack,

So, If there any simple scrip for an action button to recognise the number that show the calculator?

Something like

if
DisplayString= 55
then
add 1 to right_ factory (This would be a page variable)

the idea is to add points to a page variable if the calculator shows the right number.

Hi Isma,

It handles the update of the display in a slightly odd way depending on whether it's performing an operation or entering a value but if you swap the UpdateDisplay function in the Main Script with this version - it will get the last value on screen and store it in your price_right variable:

function UpdateDisplay()
{
var style=new Object;
style.justification="right"

DisplayString.SetSelectionParagraphStyle(style)

DisplayString.SetSelection(0,-1)
if(bStringDisplay){
DisplayString.ReplaceSelection(DISPLAY_STRING)
} else {
DisplayString.ReplaceSelection(DISPLAY_NUMBER)
}

DisplayString.SetSelection(0,-1)
price_right = DisplayString.GetSelectionText()
DisplayString.SetSelection(-1)

}

I've just hacked the three lines in red to the bottom of the function that simply selects the textbox contents and copies the text to the price_variable and then deselects the text.
