IUP 2.x are not compatible with screen readers. The reason is the
excessive usage of Canvas Draw. I did a large number of tests with IUP
and Lua and I can assure IUP 3.1 and 3.2, the last version, are very
good so in Linux as in Windows. For this reason, I would like to
translate IUP 3.2.
Ok, then I'll concentrate on IUP 3.
Yes, we can find lots of "define", but I find a problem seeming to be
more complicated.
See this declaration in C:
ihandle* IupVbox(ihandle *child, ...)
IupVbox is a vertical container wich can encompass several objects, so
it's not possible to know how many arguments it will contain.
Ok... you can translate this with FreePascal, but you must do it by hand
(so you need to comment (//...) the functions in the C header).
Here's the translation (I herby assume that a type "Pihandle = ^ihandle"
and a constant "libiup='libiup.so'" are defined):
Variant a:
Declaration:
function IupVbox(child: Pihandle; args: array of const): Pihandle;
cdecl; external libiup;
Calling:
IupVbox(Iuplabel("Label 1"), [hbox1, Nil]);
Variant b:
Declaration:
function IupVbox(child: Pihandle): Pihandle; cdecl; varargs; external
libiup;
Calling:
IupVbox(Iuplabel("Label 1"), hbox1, Nil);
The compiler won't do any checks on the arguments.
