<function name="DefineControl" parent="derma" type="libraryfunc"> <description> Defines a new Derma control with an optional base. This calls <page>vgui.Register</page> internally, but also does the following: * Adds the control to <page>derma.GetControlList</page> * Adds a key "Derma" - This is returned by <page>derma.GetControlList</page> * Makes a global table with the name of the control (This is technically deprecated and should not be relied upon) * If reloading (i.e. called this function with name of an existing panel), updates all existing instances of panels with this name. (Updates functions, calls <page>PANEL:PreAutoRefresh</page> and <page>PANEL:PostAutoRefresh</page>, etc.) </description> <realm>Client and Menu</realm> <file line="99-L127">lua/derma/derma.lua</file>⤶ <args> <arg name="name" type="string">Name of the newly created control</arg> <arg name="description" type="string">Description of the control</arg> <arg name="tab" type="table">Table containing control methods and properties</arg> <arg name="base" type="string">Derma control to base the new control off of</arg> </args> <rets> <ret name="" type="table">A table containing the new control's methods and properties</ret> </rets> </function> <example> <description>Defines a new control based off of DTextEntry that prints to the console whenever it is changed</description> <code> local PANEL = {} function PANEL:OnChange() print(self:GetValue()) end derma.DefineControl("MyTextEntry", "Printing text entry control", PANEL, "DTextEntry") </code> </example>
