Frames are like groups or windows. You can add objects on them and if you move the frame, all its children objects will also be moved. Frames also have
some special functionality to create very advanced programs.
[Object](objects/Object.md) methods also apply for frames.

This is how you would implement frames via xml:
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
```lua
local myFrame = basalt.createFrame("myFirstFrame")
```
## addFrame
Creates a child frame on the frame, the same as [basalt.createFrame](https://github.com/Pyroxenium/Basalt/wiki/Frame#basaltcreateframe) 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.<br>
#### Usage:
* Create a new main frame and adds a child frame to it
```lua
local mainFrame = basalt.createFrame()
local myFrame = mainFrame:addFrame()
```
```xml
<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
2. `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.
```lua
frame:setBar("My first Frame!", colors.black, colors.lightGray)
```
* Store the frame, use the named frame variable after assigning.
```lua
local mainFrame = basalt.createFrame()
local myFrame = MainFrame:addFrame()
myFrame:setBar("My first Frame!")
```
* This abuses the call-chaining that Basalt uses.
```lua
local mainFrame = basalt.createFrame()
local myFrame = mainFrame:addFrame():setBar("My first Frame!")
```
```xml
<frame barText="My first Frame!" barBG="black" barFG="lightGray"></frame>

<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

monitorFrame:setBar("Monitor 1"):showBar()
```
```xml
<frame monitor="right"></frame>
```
## setMirror
mirrors this frame to another peripheral monitor object.
#### Parameters:

```
## 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
```lua
local aButton = myFrame:addButton()
myFrame:setFocusedObject(aButton)

* Creates a frame with id "myFirstFrame" and makes it movable
```lua
local myFrame = basalt.createFrame():setMovable(true)
```
```xml
<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
```lua
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)
```lua
local myFrame = basalt.createFrame():setOffset(5, -5)
```
```xml
<frame xOffset="5" yOffset="-5"></frame>
```
## addLayout
Adds a new XML Layout into your frame.
#### Parameters:

```xml
<frame layout="mainframe.xml"></frame>
```
## addLayoutFromString
Adds a new XML Layout as string into your frame.
#### Parameters:
1. `string` xml

* Creates a new base frame and adds the mainframe.xml layout
```lua
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](https://github.com/Pyroxenium/Basalt/blob/master/Basalt/theme.lua) for how it could look like.
#### Parameters:

```lua
local myFrame = basalt.createFrame():setTheme({
ButtonBG = colors.yellow,
ButtonText = colors.red,
})

## Examples
Here are some examples on how you can use frames to create very advanced programs. Because of the screen size limitation of CC:Tweaked frames can become very useful in almost every scenario. You will find some examples here on how you could implement them.
### Menubar for switching frames
This is a example on how you can create a menubar which switches your frames (without animation).
<details>
<summary>Click here to show code</summary>
```lua
local basalt = require("basalt") -- we need basalt here
local main = basalt.createFrame():setTheme({FrameBG = colors.lightGray, FrameFG = colors.black}) -- we change the default bg and fg color for frames
local sub = { -- here we create a table where we gonna add some frames
main:addFrame():setPosition(1, 2):setSize("parent.w", "parent.h - 1"), -- obviously the first one should be shown on program start
main:addFrame():setPosition(1, 2):setSize("parent.w", "parent.h - 1"):hide(),
main:addFrame():setPosition(1, 2):setSize("parent.w", "parent.h - 1"):hide(),
}
local function openSubFrame(id) -- we create a function which switches the frame for us
if(sub[id]~=nil)then
for k,v in pairs(sub)do
v:hide()
end
sub[id]:show()
end
end
local menubar = main:addMenubar():setScrollable() -- we create a menubar in our main frame.
:setSize("parent.w")
:onChange(function(self, val)
openSubFrame(self:getItemIndex()) -- here we open the sub frame based on the table index
end)
:addItem("Example 1")
:addItem("Example 2")
:addItem("Example 3")
-- Now we can change our sub frames, if you want to access a sub frame just use sub[subid], some examples:
sub[1]:addButton():setPosition(2, 2)
sub[2]:addLabel():setText("Hello World!"):setPosition(2, 2)
sub[3]:addLabel():setText("Now we're on example 3!"):setPosition(2, 2)
sub[3]:addButton():setText("No functionality"):setPosition(2, 4):setSize(18, 3)
basalt.autoUpdate()

### Sidebar with buttons to switch frames
Here we will find out how to create a sidebar (which are also just frames) - the sidebar should have buttons to opens the frames for us.
<details>
<summary>Click here to show code</summary>
```lua
local basalt = require("basalt") -- we need basalt here
local main = basalt.createFrame():setTheme({FrameBG = colors.lightGray, FrameFG = colors.black})
--[[
Here we create the sidebar, on focus it should change the position to parent.w - (self.w-1) which "opens the frame"
when the focus gets lost we simply change the position to "parent.w"
As you can see we add :setZIndex(25) - this makes sure the sidebar frame is always more important than our normal sub frames.
:setScrollable just makes the sidebar frame scrollable (in case you're adding more frames)
]]
local sidebar = main:addFrame():setBackground(colors.gray):setPosition("parent.w", 1):setSize(15, "parent.h"):setZIndex(25):setScrollable()
:onGetFocus(function(self)
self:setPosition("parent.w - (self.w-1)")
end)
:onLoseFocus(function(self)
self:setPosition("parent.w")
end)
-- Once again we add 3 frames, the first one should be immediatly visible
local sub = {
main:addFrame():setPosition(1, 1):setSize("parent.w", "parent.h"),
main:addFrame():setPosition(1, 1):setSize("parent.w", "parent.h"):hide(),
main:addFrame():setPosition(1, 1):setSize("parent.w", "parent.h"):hide(),
}
--This part of the code adds buttons based on the sub table.
local y = 2
for k,v in pairs(sub)do
sidebar:addButton():setText("Example "..k) -- creating the button and adding a name k is just the index
:setBackground(colors.black)
:setForeground(colors.lightGray)
:setSize("parent.w - 2", 3)
:setPosition(2, y)
:onClick(function() -- here we create a on click event which hides ALL sub frames and then shows the one which is linked to the button
for a, b in pairs(sub)do
b:hide()
v:show()
end
end)
y = y + 4
end
sub[1]:addButton():setPosition(2, 2)
sub[2]:addLabel():setText("Hello World!"):setPosition(2, 2)
sub[3]:addLabel():setText("Now we're on example 3!"):setPosition(2, 2)
sub[3]:addButton():setText("No functionality"):setPosition(2, 4):setSize(18, 3)

### Movable frames with a program object
In this example you will see how you can add movable frames with a program object in it. It also shows you how you dynamically add new frames.
<details>
<summary>Click here to show code</summary>
```lua
local basalt = require("basalt")
local main = basalt.createFrame():setTheme({FrameBG = colors.lightGray, FrameFG = colors.black})
local id = 1
local processes = {}
local function openProgram(path, title, x, y, w, h)
local pId = id
id = id + 1
local f = main:addFrame()
:setMovable()
:setSize(w or 30, h or 12)
:setPosition(x or math.random(2, 12), y or math.random(2, 8))
f:addLabel()
:setSize("parent.w", 1)
:setBackground(colors.black)
:setForeground(colors.lightGray)
:setText(title or "New Program")
f:addProgram()
:setSize("parent.w", "parent.h - 1")
:setPosition(1, 2)
:execute(path or "rom/programs/shell.lua")
f:addButton()
:setSize(1, 1)
:setText("X")
:setBackground(colors.black)
:setForeground(colors.red)
:setPosition("parent.w", 1)
:onClick(function()
f:remove()
processes[pId] = nil
end)
processes[pId] = f
return f
end
openProgram("rom/programs/fun/worm.lua")
main:addButton():setPosition("parent.w - 16", 2):setText("Open"):onClick(function()
openProgram()
end)
basalt.autoUpdate()
```

### Resizable frames
If you want to make your frames resizeable, there is no way offered by basalt - so you would have to do it yourself. However such a implementation is very simple as you can see here.
<details>
<summary>Click here to show code</summary>
```lua
local basalt = require("basalt")
local main = basalt.createFrame():setTheme({FrameBG = colors.black, FrameFG = colors.lightGray})
local sub = main:addFrame():setSize(25, 12):setPosition(3, 3)
local function makeResizeable(frame, minW, minH, maxW, maxH)
minW = minW or 4
minH = minH or 4
maxW = maxW or 99
maxH = maxH or 99
local btn = frame:addButton()
:setPosition("parent.w", "parent.h")
:setSize(1, 1)
:setText("/")
:setForeground(colors.blue)
:setBackground(colors.black)
:onDrag(function(self, event, btn, xOffset, yOffset)
local w, h = frame:getSize()
local wOff, hOff = w, h
if(w+xOffset-1>=minW)and(w+xOffset-1<=maxW)then
wOff = w+xOffset-1
end
if(h+yOffset-1>=minH)and(h+yOffset-1<=maxH)then
hOff = h+yOffset-1
end
frame:setSize(wOff, hOff)
end)
end
makeResizeable(sub, 8, 4)
sub:addLabel():setText("Hello World")
basalt.autoUpdate()
```

### Scrollable frames
Another important feature of frames is the possibility to make them scrollable. Basalt only provides vertical scrolling for frames. If you want to make horizontal scrolling possible, you need to do it yourself. Also, if you're using :setScrollable() the amount to scroll is based on the object's y-position + height - you can change this by using :setScrollAmount(amount). Only count's for the basalt implementation of scrollable frames.
<details>
<summary>Click here to show code</summary>
```lua
local basalt = require("basalt")
local main = basalt.createFrame():setTheme({FrameBG = colors.black, FrameFG = colors.lightGray})
-- Vertical scrolling is pretty simple, as you can tell:
local sub1 = main:addFrame():setScrollable():setSize(20, 15):setPosition(2, 2)
sub1:addLabel():setPosition(3, 2):setText("Scrollable")
sub1:addLabel():setPosition(3, 12):setText("Inside")
sub1:addLabel():setPosition(3, 20):setText("Outside")
-- Here we create a custom scroll event as you can see we dont add a :setScrollable() method to our frame, instead we add a custom scroll event
local objects = {}
local sub2 = main:addFrame():setPosition(23, 2):setSize(25, 5):onScroll(function(self, event, dir)
local maxScroll = 0
for k,v in pairs(objects)do -- here we iterate trough every object and get their x position + width this way we can find out what's the maximum allowed value to scroll
local x = v:getX()
local w = v:getWidth()
maxScroll = x + w > maxScroll and x + w or maxScroll -- if you don't understand this line, http://lua-users.org/wiki/TernaryOperator
end
local xOffset = self:getOffset()
if(xOffset+dir>=0 and xOffset+dir<=maxScroll-self:getWidth())then
self:setOffset(xOffset+dir, 0)
end
end)
-- Because we need to iterate the objects, we add them into a table.
table.insert(objects, sub2:addButton():setPosition(2, 2):setText("Scrollable"))
table.insert(objects, sub2:addButton():setPosition(16, 2):setText("Inside"))
table.insert(objects, sub2:addButton():setPosition(30, 2):setText("Outside"))
