Frames are like containers, but are also normal objects. In other words, you can add other objects (even frames) to a frame; if the frame itself is visible all sub-objects (if they are set as visible) are also visible. A better description will follow.

basalt.createFrame

Creates a new non-parent frame - in most cases it is the first thing you'll need.

Parameters:

1. string name (should be unique)

Returns:

1. frame | nil The frame created by createFrame, or nil if there is already a frame with the given name.

Usage:

• Create a frame with an id "myFirstFrame", stored in a variable named frame

local myFrame = basalt.createFrame("myFirstFrame")

addFrame

Creates a child frame on the frame, the same as basalt.createFrame except the frames are given a parent-child relationship automatically

Parameters:

1. string name (should be unique)

Returns:

1. frame | nil The frame created by addFrame, or nil if there is already a child frame with the given name.
   

Usage:

• Create a new main frame and adds a child frame to it

local mainFrame = basalt.createFrame()
local myFrame = mainFrame:addFrame()

<frame></frame>

setBar

Sets the text, background, and foreground of the upper bar of the frame, accordingly.

Parameters:

1. string The title text to set the bar to
2. number The background color
3. number The foreground color

Returns:

1. frame The frame being used

Usage:

• Set the title to "My first frame!", with a background of black and a foreground of light gray.

frame:setBar("My first Frame!", colors.black, colors.lightGray)

• Store the frame, use the named frame variable after assigning.

local mainFrame = basalt.createFrame()
local myFrame = MainFrame:addFrame()
myFrame:setBar("My first Frame!")

• This abuses the call-chaining that Basalt uses.

local mainFrame = basalt.createFrame()
local myFrame = mainFrame:addFrame():setBar("My first Frame!")

<frame barText="My first Frame!" barBG="black" barFG="lightGray"></frame>

setBarTextAlign

Sets the frame's bar-text alignment

Parameters:

1. string Can be supplied with "left", "center", or "right"

Returns:

1. frame The frame being used

Usage:

• Set the title of myFrame to "My first frame!", and align it to the right.

myFrame:setBar("My first Frame!"):setBarTextAlign("right")

<frame barAlign="right"></frame>

showBar

Toggles the frame's upper bar

Parameters:

1. boolean | nil Whether the frame's bar is visible or if supplied nil, is automatically visible

Returns:

1. frame The frame being used

Usage:

• Sets myFrame to have a bar titled "Hello World!" and subsequently displays it.

myFrame:setBar("Hello World!"):showBar()

<frame bar="true"></frame>

setMonitor

monitorFrame:setBar("Monitor 1"):showBar()

<frame monitor="right"></frame>

setMirror

mirrors this frame to another peripheral monitor object.

Parameters:

1. string The monitor name ("right", "left",... "monitor_1", "monitor_2",...)

Usage:

• Creates mirror of your main frame to a monitor on the left side.

local mainFrame = basalt.createFrame():setMirror("left")

<frame mirror="left"></frame>

getObject

Returns a child object of the frame

Parameters:

1. string The name of the child object

Returns:

1. object | nil The object with the supplied name, or nil if there is no object present with the given name

Usage:

• Adds a button with id "myFirstButton", then retrieves it again through the frame object

myFrame:addButton("myFirstButton")
local aButton = myFrame:getObject("myFirstButton")

removeObject

Removes a child object from the frame

Parameters:

1. string The name of the child object

Returns:

1. boolean Whether the object with the given name was properly removed

Usage:

• Adds a button with the id "myFirstButton", then removes it with the aforementioned id

myFrame:addButton("myFirstButton")
myFrame:removeObject("myFirstButton")

setFocusedObject

Sets the currently focused object

Parameters:

1. object The child object to focus on

Returns:

1. frame The frame being used

Usage:

• Creates a new button, sets the focused object to the previously mentioned button

local aButton = myFrame:addButton()
myFrame:setFocusedObject(aButton)

removeFocusedObject

Removes the focus of the supplied object

Parameters:

1. object The child object to remove focus from

Returns:

1. frame The frame being used

Usage:

• Creates a new button then removes the focus from that button when clicking on it

local aButton = myFrame:addButton():setFocus():onClick(function() 
    myFrame:removeFocusedObject(aButton)
end)

getFocusedObject

Gets the currently focused object

Returns:

1. object The currently focused object

Usage:

• Gets the currently focused object from the frame, storing it in a variable

local focusedObject = myFrame:getFocusedObject()

setMovable

Sets whether the frame can be moved. In order to move the frame click and drag the upper bar of the frame

Parameters:

1. boolean Whether the object is movable

Returns:

1. frame The frame being used

Usage:

• Creates a frame with id "myFirstFrame" and makes it movable

local myFrame = basalt.createFrame():setMovable(true)

<frame moveable="true"></frame>

setOffset

Sets the frame's coordinate offset. The frame's child objects will receive the frame's coordinate offset. For example, when using a scrollbar, if you use its value to add an offset to a frame, you will get a scrollable frame. Objects are also able to ignore the offset by using :ignoreOffset() (For example, you may want to ignore the offset on the scrollbar itself)

The function can also be supplied with negative values

Parameters:

1. number The x direction offset (+/-)
2. number The y direction offset (+/-)

Returns:

1. frame The frame being used

Usage:

• Creates a new base frame with x offset of 5 and a y offset of 3

local myFrame = basalt.createFrame():setOffset(5, 3)

• Creates with x offset of 5 and a y offset of -5 (Meaning if you added a button with y position 5, it would be at y position 0)

local myFrame = basalt.createFrame():setOffset(5, -5)

<frame xOffset="5" yOffset="-5"></frame>

addLayout

Adds a new XML Layout into your frame.

Parameters:

1. string Path to your layout

Returns:

1. frame The frame being used

Usage:

• Creates a new base frame and adds the mainframe.xml layout

local myFrame = basalt.createFrame():addLayout("mainframe.xml")

<frame layout="mainframe.xml"></frame>

addLayoutFromString

Adds a new XML Layout as string into your frame.

Parameters:

1. string xml

Returns:

1. frame The frame being used

Usage:

• Creates a new base frame and adds the mainframe.xml layout

local myFrame = basalt.createFrame():addLayoutFromString("<button x='12' y='5' bg='black' />")

getLastLayout

returns a table of all objects this frame has created via xml (useful if you'd like to access all of them for some reason)

Returns:

1. table table with objects

setTheme

Sets the default theme of that frame children objects always try to get the theme of its parent frame, if it does not exist it goes to its parent parent frame, and so on until it reaches the basalt managers theme - which is sotred in theme.lua (Please checkout theme for how it could look like.

Parameters:

1. table theme layout look into theme for a example

Returns:

1. frame The frame being used

Usage:

• Creates a new base frame and adds a new theme which only changes the default color of buttons.

    ButtonText = colors.red,
})

setScrollable

Makes the frame scrollable with mousewheel.

Parameters:

Returns:

1. frame The frame being used

Usage:

• Creates a new base frame and makes it scrollable and sets the maximum amount to 25

local myFrame = basalt.createFrame():setScrollable():setMaxScroll(25)

XML Example

*This is how you would implement frames via xml:

<frame>
    <frame width="50%" bg="red">
        <button x="2" y="2" width="17" text="Example Button!"/>
    </frame>
    <frame x="50%+1" width="50%+1" bg="black">
        <textfield bg="green" x="2" width="100%-2" />
    </frame>
</frame>
