How to create NSD_Text dynamically depending from a NSD_CheckBox?

Question

I want to create a Textinput for the User dynamically depending from the State of a Checkbox above it.

I tried something like this:

...

Function nsDialogsPage
     nsDialogs::Create 1018
     ${NSD_CreateCheckBox} 20u 55u 50% 20u "Download with Proxy"
     Pop $testBox
     ${NSD_OnClick} $testBox button_click
     nsDialogs::Show
FunctionEnd

Function button_click
     ${NSD_GetState} $testBox $6
     ${If} $6 == 1
     ${NSD_CreateText} 20u 75u 80% 25p "Enter your Proxy ..."
     ${Else} 
     ;Remove the Text, Set it invisible or do something like this ...
     ${EndIf}
FunctionEnd

Function nsDialogsPageLeave
     ;does something with the input
FunctionEnd 

I didn't find anything on http://nsis.sourceforge.net/Docs/nsDialogs/Readme.html and I dont know how to remove the Box or make it invisible for the User or something like this, that he can't enter anything when the CheckBox is unchecked.

Take a look at EnableWindow

${NSD_CreateText} 20u 75u 80% 25p "Enter your Proxy ..."
Pop $myText

#disable control
EnableWindow $myText 0

#enable control
EnableWindow $myText 1

#hide control
ShowWindow $myText 0

#show control
ShowWindow $myText 1
