[Resolved] GUI Controls Roadblock
« on: Aug 13, 10, 11:57:29 AM »

So, I've been fiddling around with various Controls (NumericInputField/NumericUpDownButton) for quite some time now... trying to get a pair (and eventually - several pairs) of NumericUpDownButton (or NumericUpDownDragZone) GUI Controls to modify (increment/decrement) a single, separated NumericInputField Control.

Initially, this seemed like a easy task (and probably still is), but I'm hitting a couple of roadblocks and am having a hard time figuring out a couple of things with these controls. So, here's what I want to do:

1. Have a single NumericInputField (named: "myNIF"), whose value is initially, let's say: 5.
2. Have several NumericUpDownButton Controls (named: "numUP1", "numUP2", "numDN1", etc.) that will increment/decrement the value in "myNIF".

My initial roadblock was this: "The value field in a NumericInputField Control (along with several other Controls) is a String"... therefore, arithmetic operations don't work in this case... there aren't any: "myNIF.value = myNIF.value + 1" or "myNIF.value = myNIF.value - 1" operations. So, I was curious as to how I could "easily" increment and decrement the current value of the InputField without having to do hundreds of IF/THEN statements.

My second roadblock was... "How will I know when a particular UP/DOWN button is clicked?" I tried fishing around in the methods that were available with NumericUpDownButton Controls and I saw that there was a "selected" boolean. I tried checking with: if (numUp1.selected == true), but I don't think it worked out for me either. Is there another way to check whether or not a up/down button control has been selected/clicked? Or did I check this correctly? Is "Selected" the "RIGHT" way of going about it?

I then tried to just make the NumericUpDownButton Controls into just regular Buttons and use the _OnButtonMouseClicked() function... but, this only psuedo-worked the way I wanted it to. I was forced to use/have square boxes opposed to up and down arrows (since it's inherited from _button and _button use the bounded boxes).

So, if anyone can assist me in conquering these two annoying roadblocks, I'd be extremely elated!

Thanks.

1.convert the string to an integer and increment from there
2.set the field value to the new number

for the selection of button you use the _OnButtonMouseClicked method. eg:

method _onButtonMouseClick(button as NodeRef of Class _GUIButton, args references Class GUIMouseEvent)
  when button.name
    is "numUP1"
      numField as noderef of class GUINumericField = me.getNumField()
      iValue as integer = numField .value // cast current value to integer
      iValue +=1
      numField .value = iValue
    .
    is "numUP2"
      //...
    .
    default
    .
  .
.


as for button without border, you can create your own custom one.
Just create a new prototype gui, do not select anything on the "Inherit From", and select "_GUIButton" as class.
After, in property panel, set "ignoreMouseEvent" to false.  Set some custom texture and you are set.
