# Manual positioning
|
|
|
|
## Dynamic element types
|
|
|
|
This is only recommended for elements inside `gui.Container` (see below)
|
|
outside of some rare use cases that need it, as it does not support flow's
|
|
layouting elements.
|
|
|
|
If you want to generate element types from a variable, you can use
|
|
`{type = "label", label = "Hello world!"}` instead of
|
|
`gui.Label{label="Hello world!"}`. HBoxes and VBoxes can be created
|
|
this way as well (with `type = "hbox"` and `type = "vbox"`), however other
|
|
layouting elements (such as ScrollableVBox and Spacer) won't work correctly.
|
|
|
|
An example of this is in `example.lua`.
|
|
|
|
## Manual positioning of elements
|
|
|
|
You can use `gui.Container` elements to contain manually positioned elements.
|
|
|
|
```lua
|
|
gui.VBox{
|
|
gui.Label{label = "Automatically positioned"},
|
|
gui.Container{
|
|
-- You can specify a width and height if you don't want flow to try and
|
|
-- guess at the size of the container.
|
|
-- w = 3, h = 2,
|
|
|
|
-- You may embed most formspec_ast elements inside gui.Container
|
|
{type = "box", x = 0, y = 0, w = 1, h = 1, color = "red"},
|
|
{type = "box", x = 0.3, y = 0.3, w = 1, h = 1, color = "green"},
|
|
{type = "box", x = 0.6, y = 0.6, w = 1, h = 1, color = "blue"},
|
|
|
|
{type = "label", x = 2, y = 1.1, label = "Manually positioned"}
|
|
},
|
|
}
|
|
```
|
|
|
|
Note that you cannot nest layouted elements (like `gui.VBox`) inside
|
|
`gui.Container`.
