Show/hide secure frame on keybind?

[another]

If I want to implement such stuff as show/hide frames of addon for example on Button3 keybind click, like via Binding.xml

<Bindings>
	<Binding name="TEB_SHOWHIDE" default="CTRL-BUTTON3">
		SomeShowHideHandler()
	</Binding>
</Bindings>

but I have several frames with buttons shown by RegisterStateDriver - what should I do? Can I use secure functions like RegisterStateDriver/UnregisterStateDriver in SomeShowHideHandler (is this like secure snippet)? Get/SetAttribute? Access to frames through FrameRef? What should I type as state string - "show" or "hide"? Or maybe something else to show/hide without touching state driver?

Thanks.

If you just want to toggle a frame, do this:

frame:SetShown(not frame:IsShown())

otherwise I don't understand.

[elcius]

CreateFrame("BUTTON","MyToggler",UIParent,"SecureHandlerClickTemplate");
MyToggler:SetAttribute("_onclick",[[
    local frame = self:GetFrameRef("MyToken");
    if frame:IsShown() then
        frame:Hide()
    else
        frame:Show();
    end
]])
MyToggler:SetFrameRef("MyToken",TargetFrame);

/click MyToggler
SetBinding("x","CLICK MyToggler:LeftButton");

Since TBC things are much more complicated for secure frames like buttons able to cast spells (see "Iriel's Field Guide to Secure Handlers"). You can't Show/Hide such frames while in combat in insecure way.


Thanks to elcius, final code slightly more complicated but it works. In case someone find it useful (as is):

somewhere in Init before creating frames

	CreateFrame("BUTTON", "TEB_Toggler", UIParent, "SecureHandlerClickTemplate")
	TEB_Toggler:SetAttribute("_onclick", TEB_ToggleSnippet)
	TEB_Toggler:SetAttribute("toggle_enabled", false)
	SetBinding("CTRL-BUTTON3", "CLICK TEB_Toggler:LeftButton")

snippet

local TEB_ToggleSnippet = [=[
	--print("TEB_ToggleSnippet")
	local count = self:GetAttribute("FramesCount")
	--print("FramesCount", count)
	
	local toggle_enabled = self:GetAttribute("toggle_enabled")
	toggle_enabled = not(toggle_enabled)
	self:SetAttribute("toggle_enabled", toggle_enabled)
	
	if count then
		for i = 1, count do
			local bf = self:GetFrameRef("TEB_ButtonFrame"..i)
			--print("bf", bf)
			if bf then
				--print(bf:GetName())
				if toggle_enabled then
					--print("Hide")
					UnregisterStateDriver(bf, "visibility")
					bf:Hide()
				else
					--print("Show")
					bf:Show()
					local DriverString = bf:GetAttribute("StateDriverString")
					if DriverString then
						RegisterStateDriver(bf, "visibility", DriverString)
					end
				end
			end
		end
	end
]=]

on creating frame affected by all that stuff

function TEB_ButtonFrame_New(id, parent)
	local bf = _G[parent:GetName().."ButtonFrame"..id]
	if not(bf) then
		bf = CreateFrame("Frame", parent:GetName().."ButtonFrame"..id, UIParent, "TinyExtraBarsButtonFrameTemplate")

		local count = TEB_Toggler:GetAttribute("FramesCount")
		if not(count) then
			count = 1
		else
			count = count + 1
		end
		TEB_Toggler:SetAttribute("FramesCount", count)
		TEB_Toggler:SetFrameRef("TEB_ButtonFrame"..count, bf)
	end
...

on updating visibility driver

...
	local customText = self.visibility["Custom"]
	if (customText ~= "") then
		RegisterStateDriver(self, "visibility", text..customText)
		self:SetAttribute("StateDriverString", text..customText)
	else
		if (text ~= "") then
			RegisterStateDriver(self, "visibility", text.."show")
			self:SetAttribute("StateDriverString", text.."show")
		else
			UnregisterStateDriver(self, "visibility")
			self:SetAttribute("StateDriverString", "")
		end
	end
