UI_PICT_PUSHCHECKBUTTON{2} with boolean array?

[Karl Wir_n]

I'm trying to use UI_PICT_PUSHCHECKBUTTON{2} to set values in a 3-dimensional boolean array. This doesn't work correctly. When switching to a 1-dimensional array it works as expected. Is there a limitation that is not mentioned in the GDL Reference Guide?

What is a 3-dimensional Array in GDL ?
Array[1][1][1] ist not available in GDL, only 2-dimensional.

Sorry, I meant 2-dimensional. The question remains though.

I just tested it and it seems to work fine for me.

For a quick test, I created a boolean parameter "bTest" and made it bTest[4][4]

UI Script ;

dim testTxt[4][4]
for i = 1 to 4
	for j = 1 to 4
		testTxt = "Dim1 =" + str(i, 1, 0) + ", Dim2 =" + str(j, 1, 0)
	next j
next i

!-----------------------------------------------
! Try changing i and j below
i = 1	! Use value between 1 to 4
j = 1	! Use value between 1 to 4
!-----------------------------------------------

UI_PICT_PUSHCHECKBUTTON{2} bTest, testTxt, "",         
	1, 10, 40, 120, 120

Yeah I just ran into this problem too, it seems that the second array dimension isn't taken into account.

For example Parameter[3][1] will actually change Parameter[3][3], like wise for [2][1] changing [2][2].

It's basically turning a 2 dimension array into a 1 dimension array down the diagonal.

Pretty frustrating.

And while on the topic, none of the written pushbutton options for boolean parameters respond to the UI_STYLE settings.

I'm afraid, guys, UI_PICT_PUSHCHECKBUTTON{2} is working with boolean only, that can be only 1 or 0. Without any arrays.
My advice - create necessary variable for the button (I often user UI-prefix for such variables) and if there is dependency between arrays in the script and this button variable - use PARAMETERS in parameter script to set the value.
I have learned, that sometimes just re-organising the algorithm of the script differently can solve almost unsolvable parts.
