Is there an "Undo Script" Tool for drawing tablets?

Not tested this, but you could try this. Save it as LK_Undo.lua in your tools folder. If it works you can also create a redo button next to it, just change all instances of 'undo' into 'redo'

Code: Select all

-- **************************************************
-- Provide Moho with the name of this script object
-- **************************************************

ScriptName = "LK_Undo"

-- **************************************************
-- General information about this script
-- **************************************************

LK_Undo = {}

function LK_Undo:Name()
	return "Undo"
end

function LK_Undo:Version()
	return "0.1"
end

function LK_Undo:Description()
	return "Undo"
end

function LK_Undo:Creator()
	return "Lukas Krepel, Frame Order"
end

function LK_Undo:UILabel()
	return "Undo"
end

function LK_Undo:IsEnabled(moho)
	return true
end

function LK_Undo:IsRelevant(moho)
	return true
end

function LK_Undo:ColorizeIcon(moho)
	return true
end


-- **************************************************
-- The guts of this script
-- **************************************************
function LK_Undo:Run(moho)
	moho.document:Undo()
end

Thanks! I tried but it doesn't work. It shows an "unknown" icon in "Other" tools panel but when clicked, no response.

Ah I see

Code: Select all

ScriptName = "Undo"

should have been:

Code: Select all

ScriptName = "LK_Undo"

I updated the previous post, it should run now

Thank you very much!

No problem!

You know what, here's both undo and redo with icons, I see how this would be useful for tablets:

LK_UndoRedo.zip

Here's a zip file with the LUA, PNG icons, Read Me, and Moho document...

That's funny! We were thinking the same thing. I made new icons though.

Ha

nice

I renamed the "Undo" files, so that the Undo icon shows before the Redo icon in Moho. It's "LK_1_Undo" now.

Actually, you can quite easy edit the order the tools are shown in by editing the _tools_list.txt file in the tools folder. So you don't have to change the names to re-order them.

Also, you can have the icons be greyed out if there's nothing to undo/redo by changing the IsEnabled function to this:

Code: Select all

function LK_Undo:IsEnabled(moho)
	if moho.document:IsUndoable() then
		return true
	end
	return false
end

(I updated/reuploaded my .zip)

The recommended way is to use the GUI: Edit > Preferences > Tool Layout (even though it is painful if you want to move a lot of stuff around!).
