Macro column_layout

macro_rules! column_layout {
    ($bounds:expr, $gravity:expr, $(padding: $padding:expr,)? $(spacing: $margin:expr,)? views: $($views:expr),+ $(,)?) => { ... };
}

Update the position multiple views to be in a column if gravity is

• Left - then only the top_left of bounds is used
• Center - then only the center of bounds is used
• Right - then only the bottom_right of bounds is used

padding is used to offset views from the relevant position

spacing is space between views

Usage

 let button1 = Button::new("Button", ...);
 let button2 = Button::new("Button", ...);
 let button3 = Button::new("Button", ...);
 column_layout!(Rect::new((16,16),(16,16)), ColumnGravity::Left, padding: 2, spacing: 8,  views: button3, button1, button2);
 // button3 top left will be (18, 18)
 // button1 top left will be (18, 18 + 8 + button3.height)
 // button2 top left will be (18, 18 + 8 + button3.height + 8 + button2.height)
