Is it possible to write something in a specific line in a uilistbox?

Hi as the title says is it possible to easy fill a line in an UiList Box?
like
replace=panel:getListBox(“RAM1ToneBank”):setPropertyString(“uiListBoxContent”,”word”)
and lets say and want that in line 8?

Thx

No, you can only replace the entire string.

Best way is create a table to hold each line. Update the relevant table entry.

When you need to update the list is content call a method that cycles through each table element concatenating with /N and then write the resulting string to the list is.

There’s an example in the miniak panel for the program list.

Without knowing it was in another panel, I have also used that technique: rebuilding and replacing the full string of names.
This is faster and easier than searching in the content string and replacing a piece (you need to store what is before and what is after) of it.

I put this in a separate method that I can call for any listbox: RefreshListBoxContent(memoryblock). So, only one program but re-used several times 🙂
It is based on a memory block in my case as I have sound banks as memory blocks and I extract the program names from the bank (20 char string).

Here is the code you can get inspired from:

RefreshBankListBox = function(mbBank)

	FileSize = mbBank:getSize()

	if FileSize == 116622 then
		sListBoxContent = ""
		for i=0, 98 do
			UnpackedTempData = utils.unpackDsiData(mbBank:getRange (438+i*1178, 24))
			sTemp = trim(UnpackedTempData:getRange (0, 20):toString())	-- Remove blanks
			sTemp = sTemp:gsub("'", " ")	-- Replace ' by a space as it gives issues in the listbox
			sTemp = sTemp:gsub("\"", " ")	-- Replace " by a space as it gives issues in the listbox
			if i==0 then
				sListBoxContent = sListBoxContent..string.format("%s", "P1 "..sTemp)
			else
				sListBoxContent = sListBoxContent..string.format("\n%s", "P"..tostring(i+1).." "..sTemp)
				--sListBoxContent = sListBoxContent..", \""..sTemp.."\""
			end
		end
		return sListBoxContent
	else
		utils.warnWindow("Refresh bank list box", "Error: bank data not of correct size. Should be 116622 and is "..FileSize.." bytes.")
	end

end

To use it:
lbUser1:setPropertyString ("uiListBoxContent", RefreshBankListBox(mbUser1))

With lbUser1 being a uiListBox declared as:
lbUser1 = panel:getListBox("User1")
