Lua Scripting

This component supports executing a script function when its value changes. The current value can be obtained by using GetValue() method and changed using SetValue(), for example here is a function that could be used to maintain the sum of two sliders values constant:

Lua:

function OnSlider(slider, event) local value = slider:GetValue(); local slider2 = okUI:FindPanel("panel1"):FindSlider("slider2") slider2:SetValue(255 - value) end
Code language: JavaScript (javascript)

Assuming the panel contains the following elements:

XML:

<object class="okSlider"> <position>15,15</position> <size>200,30</size> <style>HORIZONTAL</style> <minvalue>0</minvalue> <maxvalue>255</maxvalue> <value>0</value> <functionname>OnSlider</functionname> </object> <object class="okSlider" name="slider2"> <position>15,50</position> <size>200,30</size> <minvalue>0</minvalue> <maxvalue>255</maxvalue> <value>255</value> </object>
Code language: HTML, XML (xml)

All XML components that support Lua scripting also inherit from the Control class. Please refer to the FrontPanel Scripting documentation for more information on this class.
