So I thought I d try XCB instead but there seems to be some kotlinlang #kotlin-native

So I thought I'd try XCB instead, but there seems to be some problem with structs, so that's not working either. 😫 @olonho Did you see the thing I pasted? Any hints?

yes, we see the problem and try to fix it soon.

We have fixed returning structs by value in master branch. Could you please try XCB again?

It's working now, thanks! 👍 Now I'm just having some trouble filling in the array of structs (xcb_rectangle_t) that needs to be passed to the drawing function. I can do "r = allocArray<xcb_rectangle_t>", access the struct with "r[0]", and successfully fill in the fields... but the last of the fields seems to be ignored somehow.

Where by ignored I mean that my rectangle gets a position and a width, but no height. But also something more weird: the fields are all shorts, and when I try to assign ints to them the compiler complains – but not for the last field! If I assign a String to the last field the compiler says it requires a Short, but if i assign an Int it compiles without complaints. 🤔

Does it work correctly if you assign shorts to last fields?

No, the rectangle still doesn't get a height (i.e. it's drawn as a line).

Maybe there's a better way to create it? The C documentation says: xcb_rectangle_t rectangles[] = {{ 10, 50, 40, 20}, { 80, 50, 10, 40}};

Currently there is no way better than manually filling struct fields. Of course it is still possible to hide this in a method 🙂

No, the rectangle still doesn't get a height (i.e. it's drawn as a line).

Could you please provide a sample?

Well.... 😅 I made a minimal sample and it worked perfectly. It turns out I had misspelled the parameter name as "heigth", so "this.height = height" was just reassigning itself to itself! My bad. (The compiler even warned me about it, but it got lost among the spurious "failed to obtain inline function declaration" warnings.)
