Basalt 1.7 Update

- New Objects (Flexbox, Graph, Treeview)
- Pluginsystem to add/remove functionality
- Reworked the entire Object system, instead of one big Object Class we have multiple classes: Object, VisualObject, ChangeableObject
- Instead of one big Frame Class we have multiple Frame Classes: BaseFrame, Frame, MovableFrame, ScrollableFrame, MonitorFrame, Flexbox
- Removed the Animation Object, and added a animation plugin instead
- Removed the Graphic Object and merged it's functionality with the image object
- Updated currently existing objects

Here I want to explain to you how you would create a button with the default color gray, and as long as the user is clicking on the button it will change its color to black (the default frame-background is lightGray).
To make this possible the button needs 1 onClick event, 1 onClickUp event and 1 onLoseFocus event.
Very interesting sidetip: events can hold multiple functions!<br>
**Example snippet:**
```lua
local function buttonColoring()
-- here you can add some coloring for your button
end
local function buttonLogic()
-- here you can add some logic for your button
end
local button = mainFrame:addButton("ExampleButton"):show()
button:onClick(buttonColoring):onClick(buttonLogic) -- yes this would work, if not its a bug!
```
This means you can create a function wich handles only the coloring side of your button, and if your button also needs some logic you just create your own unique function for that and add it to your button.
With this knowledge we create now a function where we pass a button-object as parameter and this will setup the coloring of our button:
**Example snippet:**
```lua
local basalt = dofile("basalt.lua")
local mainFrame = basalt.createFrame("mainFrame"):show()
local button = mainFrame:addButton("firstButton"):setPosition(3,3):setSize(12,3):setText("Click me"):setBackground(colors.gray):setForeground(colors.black):show()
local button2 = mainFrame:addButton("secondButton"):setPosition(25,3):setSize(16,3):setText("Another Btn"):setBackground(colors.gray):setForeground(colors.black):show()
local function setupButtonColoring(btn)
btn:onClick(function() btn:setBackground(colors.black) btn:setForeground(colors.lightGray) end)
btn:onClickUp(function() btn:setBackground(colors.gray) btn:setForeground(colors.black) end)
btn:onLoseFocus(function() btn:setBackground(colors.gray) btn:setForeground(colors.black) end)
end
setupButtonColoring(button)
setupButtonColoring(button2)
basalt.autoUpdate()
```
Now you've got a function which sets your buttons up.

Hello! This page contains some tips on how to create cool designs with Basalt
To understand this page, it is recommended to familiarize yourself with [Animations](../objects/Animation.md) as animations are important for creating complex designs
Let us begin with simple things:
## Recolor objects
Let's create a Button:
```lua
local basalt = require("Basalt")
local mainFrame = basalt.createFrame():setBackground(colors.black):show()
local aButton = mainFrame:addButton():setSize(10, 3):setText("Beautiful"):setBackground(colors.gray):show()
```
Here lets make use of the event system:<br>
```lua
local function changeButtonColor(self,event,typ,x,y)
if(event=="mouse_click")then
self:setBackground(colors.lightGray)
end
if(event=="mouse_up")then
self:setBackground(colors.gray)
end
end
local function buttonLogic()
-- here you can do some logic when button gets the mouse_up event
end
aButton:onClick(changeButtonColor) -- button color change on click
aButton:onClickUp(changeButtonColor) -- button color change on click up
aButton:onClickUp(buttonLogic) -- button logic on click up
aButton:onLoseFocus(function(self) self:setBackground(colors.gray) end) -- if user is clicking on the button and dragging out of button size this event will change the bg color back to gray
```
## Fade In/Out Objects
instead of recoloring we are also able to slowly reposition the button, something like fade in:<br>
```lua
local buttonAnimation = mainFrame:addAnimation()
local function fadeButtonIn(btn)
if(btn.x < 5)then
btn:setPosition(1,0,"r")
else
buttonAnimation:cancel() -- here you cancel the loop
end
end
buttonAnimation:wait(0.1):add(function() fadeButtonIn(aButton) end):play(true) -- with play(true) you will create a infinite loop
```
This is also possible with entire frames and its children objects. So keep that in mind if you want to create something like a bigger panel to the right or a menu bar
## How To use XML
Here is a example on how to create a cool looking frame by using xml:
```xml
<frame width="parent.w/2" bg="gray" scrollable="true" importantScroll="true">
<button x="2" y="2" width="parent.w-2" bg="black" fg="lightGray" text="Example Button 1!"/>
<button x="2" y="6" width="parent.w-2" bg="black" fg="lightGray" text="Example Button 2!"/>
<button x="2" y="10" width="parent.w-2" bg="black" fg="lightGray" text="Example Button 3!"/>
<button x="2" y="14" width="parent.w-2" bg="black" fg="lightGray" text="Example Button 4!"/>
<button x="2" y="18" width="parent.w-2" bg="black" fg="lightGray" text="Example Button 5!"/>
<button x="2" y="22" width="parent.w-2" bg="black" fg="lightGray" text="Example Button 6!"/>
<button x="2" y="26" width="parent.w-2" bg="black" fg="lightGray" text="Example Button 7!"/>
</frame>
<frame x="parent.w/2+1" width="parent.w/2+1" bg="black">
<textfield bg="gray" x="2" y="2" width="parent.w-2">
<lines>
<line>This is line 1.</line>
<line>And this is line 2.</line>
</lines>
</textfield>
<label anchor="bottomLeft" x="2" y="0" text="I love labels!" fg="lightGray"/>
</frame>
```
in your lua code you just have to add this layout to your frame:
```lua
local basalt = require("Basalt")
basalt.createFrame():addLayout("example.xml")
basalt.autoUpdate()
```

## Short way of adding functions to events
Not everyone knows that a function (or in other words a method) does not need to have a name. Instead of a function name you are also able to add the function itself as a argument.
Both do the exact same thing:
```lua
local function clickButton()
basalt.debug("I got clicked!")
end
button:onClick(clickButton)
```
```lua
button:onClick(function()
basalt.debug("I got clicked!")
end)
```
## Using isKeyDown for shortcuts
there is also a function with which you can check if the user is holding a key down, it is called `basalt.isKeyDown()`. It's especially useful for click events.
Let us say you want a button to execute something, but if you are holding ctrl down, something in the execution should get changed. This is how you would
achieve that:
```lua
button:onClick(function()
if(basalt.isKeyDown(keys.leftCtrl)then
basalt.debug("Ctrl is down!")
else
basalt.debug("Ctrl is up!")
end
end)
```
Make sure to always use the available `keys` table: https://computercraft.info/wiki/Keys_(API)

You question yourself how you can execute your own logic while basalt is also active? There are multiple ways of doing that:
## Method 1:
Using parallel.waitForAll
```lua
local basalt = dofile("basalt.lua")
local mainFrame = basalt.createFrame("mainFrame"):show()-- lets create a frame and a button without functionality
mainFrame:addButton("aButton"):onClick(function() end):show()
local function yourCustomHandler()
while true do
-- add your logic here
os.sleep(1) -- you need something which calls coroutine.yield(), yes os.sleep does that os.pullEvent() aswell
end
end
parallel.waitForAll(basalt.autoUpdate, yourCustomHandler) -- here it will handle your function (yourCustomHandler) and basalts handlers at the time
```
You can read [here (tweaked.cc)](https://tweaked.cc/module/parallel.html) what exactly parallel.waitForAll() does
## Method 2:
Using threads
```lua
local basalt = dofile("basalt.lua")
local mainFrame = basalt.createFrame("mainFrame"):show()-- lets create a frame, a button without functionality and a thread
mainFrame:addButton("aButton"):onClick(function() end):show()
local thread = mainFrame:addThread("customHandlerExecutingThread")
local function yourCustomHandler()
while true do
-- add your logic here
os.sleep(1) -- you need something which calls coroutine.yield(), yes os.sleep does that os.pullEvent() aswell
end
end
thread:start(yourCustomHandler) -- this will create a coroutine and starts the coroutine, os.sleep does the rest, so you just have to call start once.
```
## Method 3:
Using timers
```lua
local basalt = dofile("basalt.lua")
local mainFrame = basalt.createFrame("mainFrame"):show()-- lets create a frame, a button without functionality and a timer
mainFrame:addButton("aButton"):onClick(function() end):show()
local timer = mainFrame:addTimer("customHandlerExecutingTimer")
local function yourCustomHandler()
-- add your logic here
end
timer:onCall(yourCustomHandler):setTime(1, -1):start() -- this will call your function every second until you :cancel() the timer
```
