Overview

Text controls displays text on the current window. Slab currently offers three ways to control the text. Examples of each can be found below.

Slab.BeginWindow('MyFirstWindow', {Title = "My First Window"})

Slab.Text("Hello World")

Slab.EndWindow()

Text Selectable

Selectable text will respond to user input. This is useful for building lists within the window.

Slab.BeginWindow('MyFirstWindow', {Title = "My First Window"})

for I = 1, 10, 1 do
	if Slab.TextSelectable("Selectable Text " .. I) then
		Selected = I
	end
end

Slab.Separator()

if Selected == 0 then
	Slab.Text("No item selected.")
else
	Slab.Text("Selected Text " .. Selected)
end

Slab.EndWindow()

Text Formatted

Text can also be wrapped and aligned within the contents of the window. It will automatically adjust the wrapping as the window size changes.

Slab.BeginWindow('MyFirstWindow', {Title = "My First Window", AutoSizeWindow = false})

Slab.Textf("Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut" ..
	" labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi " .. 
	"ut aliquip ex ea commodo consequat. Duis aute irure dolor in reprehenderit in voluptate velit esse cillum " ..
	"dolore eu fugiat nulla pariatur. Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum.")

Slab.EndWindow()
