Button

Buttons are objects, which execute function by clicking on them

Here is a example of how to create a standard button:

````lua
local mainFrame = basalt.createFrame("myFirstFrame"):show()
local aButton = mainFrame:addButton("myFirstButton"):show()
````

This will create a default button with the size 5 width and 1 height on position 1 1 (relative to its parent frame), the default background is colors.lightBlue, the default text color is colors.black and the
default zIndex is 5. The default vertical and horizontal text aligns are "center" - but there is no default text.

Here are all possible functions available for buttons. Remember button inherit from [object](https://github.com/NoryiE/basalt/wiki/Object):

## setText
Sets the displayed button text
````lua
local mainFrame = basalt.createFrame("myFirstFrame"):show()
local aButton = mainFrame:addButton("myFirstButton"):setText("Click"):show() -- you could also use :setValue() instead of :setText() - no difference
````
**args:** text<br>
**returns:** the object<br>

# Examples
Add a onClick event:
````lua
local mainFrame = basalt.createFrame("myFirstFrame"):show()
local aButton = mainFrame:addButton("myFirstButton"):setText("Click"):onClick(function(self,event,button,x,y)
if(event=="mouse_click")and(button==1)then
basalt.debug("Left mousebutton got clicked!")
end
end):show()
````
