## Padding, spacing, and backgrounds
|
|
|
|
All elements can have a `padding` value, which will add the specified amount of
|
|
padding around the element. The "root" element of the form (the one returned by
|
|
`build_func`) has a default padding of 0.3, everything else has a default
|
|
padding of 0.
|
|
|
|
`HBox` and `VBox` have a `spacing` field which specifies how much spacing there
|
|
is between elements inside the box. If unspecified, `spacing` will default to
|
|
0.2.
|
|
|
|
Container elements (HBox and VBox) can optionally have `bgimg` and `bgimg_middle`
|
|
parameters that specify a background for the container. The background will be
|
|
drawn behind any padding that the container has.
|
|
|
|
Example:
|
|
|
|
```lua
|
|
gui.VBox{
|
|
padding = 0.5,
|
|
spacing = 0.1,
|
|
|
|
-- bgimg can be used without bgimg_middle
|
|
bgimg = "air.png",
|
|
bgimg_middle = 2,
|
|
|
|
gui.Button{label="Button 1"},
|
|
gui.Button{label="Button 2"},
|
|
}
|
|
```
|
|
|
|
|
|
|
|
The padding around the VBox is 0.5 and the spacing between the buttons inside
|
|
it is 0.1.
