[BUG] LabelType::Multi causes segmentation fault

[crumblingstatue]

Setting the label type of a widget to LabelType::Multi causes segmentation fault.

Here is code to reproduce:

use fltk::{app::*, window::*, frame::*};

fn main() {
	let app = App::default();
	let mut win = Window::default().with_size(400, 400);
	let mut f = Frame::default().with_label("hi").size_of(&win);
	f.set_label_type(LabelType::Multi);
	win.show();
	app.run().unwrap();
}

Expected behavior
I have no idea what Multi label type does, I was just experimenting.

Meta info

• OS: Arch Linux x86_64
• FLTK Version 0.14.5

I’ll have to check when I get home.

Are the other label types also causing issues?
A multilabel supports an image and text at the same time.

Edit: the implementation on FLTK’s side appear more involved. It requires an Fl_Multi_Label class, setting the image and text then setting the label. I think I’ll remove it for now until I create a MultiLabel struct and impl.

I have disabled LabelType::Multi in master. To combine an image with text, one can override the WidgetBase::draw call.

Edit: The changes were published in the 0.15 version.
