[Lua] Transparency of CE via slider
Posted: Wed Aug 25, 2021 9:30 pm
This snippet creates a form and allows the user to set the transparency value in percentage, based on the slider position. It also shows how to create and set components and their options programmatically.
Can be used for the Lua Engine form also, just decomment the appropriate lines.

tSettings.Width = ce.Width
tSettings.Height = 100
tSettings.Left = ce.Left + 5
tSettings.Top = ce.Top + (ce.Height + ((tSettings.Height / 2) - 15))
local tb = createTrackBar(tSettings)
