Option to truncate text in Label

[AlanRace]

Label currently ignores the max size when adding via add_sized. This only seems to be taken into account when wrap is set to true. I would ideally like to set a maximum size for the label and then simply have it not display any text that doesn't fit in the specified width (possibly replacing it with ... to indicate the full label is not being displayed).

ui.horizontal(|ui| {
    ui.add_sized([100.0, 10.0], egui::Label::new("My very long description"));
    ui.button("Remove");
}

Regardless of the specified width in add_sized, the label is displayed in full.

As a proposed solution, perhaps an API similar to the below:

/// Describes how to handle exceeding allocated size for the widget (label)
enum ExceedDimension {
     /// Force extend the dimension (e.g. width/height) of the label so that all text is displayed
     Extend,
     /// Wrap the text so that it fits within the specified width, but 
     /// potentially extends the height past the requested size
     Wrap,
     /// Truncate text so that it fits within the specified bounds
     Truncate,
}

// ...

ui.horizontal(|ui| {
    ui.add_sized(
        [100.0, 10.0], 
        egui::Label::new("My very long description").on_exceed_width(ExceedDimension::Truncate)
    );
    ui.button("Remove");
}

Alternatively, maybe there is a different way to achieve what I am trying to achieve - essentially as in the example above, I would like to always have the button visible at the cost of the full description. This appears in a SidePanel so I want the width to be tied to the current width of the SidePanel (minus the width of the button) so that the button always appears at the very right of the screen/panel.

Truncating with … would be a nice option to have.

I concur, I would really like to have this feature :)
