Create Dynamic Buttons

[crugh]

Hi,

Is it possible to load an external file with questions and answer choices that the MMF2 application reads and then dynamically creates the number of buttons with relation to the number of questions on the file?

If the user makes a quiz with 5 questions then there are 5 buttons created along the bottom for each question. For example, when the user clicks button 2 then the 2nd question with the choices is shown.

I am trying to create a quiz application in MMF2 that I originally created in flash.

Thanks in advance.

Yes, it is possible. I'd use INIs and loops, and determine which button is which by their X position.

Do you want a variable amount of possible answers or, for example, have four (differing) choices for every question?

Thanks for the reply. I would have four choices per question.

I think I understand your approach- load the INI file and loop through it adding a button for each question until the end of the file. Then determine which button by the x (y) position on mouseover or when clicked to display the question with the 4 choices.

Exactly. You could also use the Y position if you had multiple rows.

All you need is to make one button and use the "duplicate" facility. This should mean that all buttons have a determinable X/Y if you take into account the distance and the offset. You can then do a loop to populate the buttons with the correct title and to determine which button it is. Use str$() to convert a number (e.g. loop step) into an string.

Oh, and the easiest way to do it would be to have one INI group per question, and an item in a seperate group (or no group) which contains the amount of questions. Alternatively, you could have it keep going to the next group (1,2,3,etc) until it finds one with a blank item for the question field. A loop told to run -1 times should run until stopped.

Thank you for the details to get started.

I am new to MMF2 and this really helps. The application may have multiple rows depending how many questions were created.
