[solved] How to get display the selected text of an uilistbox somewhere else?

[iceleben]

As the title says how do I get the selected text of an Uilistbox displayed somewhere else? The funny thing is that an Ui Label with the “display last selected modulator” checked shows it so it has to be accessible somehow. I can only get the value or the complete List but not the individual selected text…

Hi,
I have implemented that in my Pro 2 librarian (soon to be published). I’m using Lua methods to copy the selected item of a uiListbox into a uiLabel.
I’ll also describe it extensively in the Step by Step guide 2.0.

If you know the item that has been clicked (I can also give you the code and logic for that), you can use the following statement:
txtSource:getComponent():setPropertyString ("uiLabelText", L(lbDisk1:getTextForValue(iLastSelectedProgram)))

where

• txtSource is your label modulator. I defined txtSource = panel:getModulatorByName(“txtSource”) during panel initialization
• lbDisk1 is your list box. I defined lbDisk1 = panel:getListBox(“Disk1”) during panel initialization
• iLastSelectedProgram is your item number in the list box

Let me know if you need more hints…

[iceleben]

Hi Goodweather,

Ahhhh me stupid it I get it….iLastSelectedProgram is not a value by Default but one you defined

xu=panel:getModulatorByName(“FactoryBank1”):getModulatorValue()
lbDisk1 = panel:getListBox(“FactoryBank1”):getTextForValue(xu)

panel:getComponent(“LCD10”):setPropertyString (“uiLabelText”,lbDisk1)
end

works fine

Thx so much Goodweather – Ctrlr is getting better Each day I work with it! But then I want to Change a lot of stuff I did before 😉

Nice to read!
Yes, iLastSelectedProgram is a variable containing the selected Item.
In my Pro 2 implementation, I’m doing the complete management based on mouse clicks. You don’t need to select an actual value with a modulator but just clicking on the program you want to load.
But that’s another story 🙂

[iceleben]

is there an easy way to convert the lbDisk1 Data from the above example to a string if I have the
panel:getComponent(“LCD10″):setPropertyString (“uiLabelText”,lbDisk1) set to
panel:getComponent(“LCD10″):setPropertyString (“uiLabelText”,string.format(“%s”,lbDisk1))

[goodweather]

What do you want to do? I don’t follow you.
The whole content of a uiListBox is already a string…
You set it with setPropertyString (“uiListBoxContent”, “Your content”) and you get it with getPropertyString (“uiListBoxContent”).

You can assemble the content of a uiListBox with a loop like:

for i=0, 98 do
	if i==0 then
		sListBoxContent = sListBoxContent..string.format("%s", "P1 "..sTemp)
	else
		sListBoxContent = sListBoxContent..string.format("\n%s", "P"..tostring(i+1).." "..sTemp)
	end
end

The first program should not have a return before all the other ones well.
sTemp is the name of each program (I have removed here the way I’m getting it and you need to replace by your own stuff).

[iceleben]

What I’d like to do is – I already have an ui LCD Modulator that is showing some stuff

panel:getComponent(“ComScreen”):setPropertyString (“uiLabelText”,string.format(“%s %s %s %s %s %s”,lors,ramrom,bnkscreen,bnr,pot,ToneNbr))

and in the “pot variable” I’d like to show the clicked selected box text. At the moment with the above example I get the error “string expected got userdata”

[goodweather]

Always easier when you know the goal 🙂

Create a method that you can call BankItem_OnClick with type uiListBoxItemClicked.
When using it, the variable “value” will contain the number of the selected item.
So, in that method you can update your LCD with the code:

panel:getComponent(“ComScreen”):setPropertyString (“uiLabelText”,string.format(“%s %s %s %s %s %s”,lors,ramrom,bnkscreen,bnr,value,ToneNbr))

Compile the method then select your listbox and set the property “Called when Item is clicked” (somewhere at the bottom of the properties list) to BankItem_OnClick

Should work fine…

[iceleben]

Hi Goodweather,

thx again, I tried it with:
BankItem_OnClick=function(uiListBoxItemClicked,value)
panel:getComponent(“LCD10”):setPropertyString (“uiLabelText”,string.format(“%s”,value))
end
but then again I get the number displayed but not the text from the List box

But finally after a lot of ” I am groot” moments I found a solution that works and might be interesting for userdata Problems

TextTestDisplay=function()
xu=panel:getModulatorByName(“FactoryBank1”):getModulatorValue()
lbDisk1 = panel:getListBox(“FactoryBank1″):getTextForValue(xu)
xyz=lbDisk1+”” –this little sucker converts userdata to a string
panel:getComponent(“LCD10”):setPropertyString (“uiLabelText”,string.format(“%s”,xyz))
end

My Brain hurts 😉

[goodweather]

Well… different things

• Your method must be (type it exactly like this): BankItem_OnClick = function(–[[ CtrlrModulator –]] modulator, –[[ number –]] value)
• within the method code, “value” is the number of the item clicked. If you want to display it, use console(tostring(value)). tostring() is much easier than string.format
• if you need the text corresponding to the “value” then use L(lbBank1:getTextForValue(value))

Good luck!

[iceleben]

Goodweather, youre the Scripting hero!
works fine:
BankItem_OnClick = function(–[[ CtrlrModulator –]] modulator, –[[ number –]] value)
xyz=L(panel:getListBox(“FactoryBank1”):getTextForValue(value))
panel:getComponent(“LCD10”):setPropertyString (“uiLabelText”,string.format(“%s”,xyz))
end
So if I understand correctly in the function line there is the reference for modulator with its value being made.
And then in the xyz…line the Modulator is ” panel:getListBox(“FactoryBank1″):” with the value being converted to the the Text…what exactly does the L stand for?

Good 🙂

BankItem_OnClick is a callback function this means that it will be called each time you click on an item if you assign that function to your uiListbox property “Called when Item is clicked”. Basically, this is what you want to do: refresh your LCD each time an item is clicked…

I see you are using panel.getComponent(“LCD10”). Did you initialize all your modulators somewhere? In fact you should create a method containing all your modulators initialization like xyz = panel.getModulatorByName(“Bank1”) and you assign that method to your panel property “Called when panel is loaded”.
Then in all your methods, you don’t need to refer to the actual name of the modulator and the performance will be better as Ctrlr doesn’t need to go through the list of modulators to search their names (explained by Atom somewhere in the forum).
So, in your methods you simply use: xyz.getComponent().setPropertyString… to reach the component part within the Bank1 modulator.
In my Pro 2 panel I define things like lblLCD10 = panel.getModulatorByName(“LCD10”) to indicate it is a label that the user cannot change. I have also modSomething for all buttons; the Something being the same as the actual name of the modulators. Advantage is that I always know what type of component I’m handling (as long as I respect my own rule…).

About the L() function, I got the tip from dasfaker who had a similar problem. It is a string conversion function that must be used sometimes when comparing string objects.
Quote from Atom:

I think this might be a Lua issue in it’s core you are comparing a object of type String() and a string, getLuaName() is an alias to getName() and they both return a String()

so in order to compare the actual String() content you should do something like

m = panel:getModulatorByName (“very fucked up modulator”)
console (m:getName())
if L(m:getName()) == “very fucked up modulator” then
console (“Yup i got that modulator i needed”)
else
console (“Nope couldn’t get it”)
end
That is put the modulator:getName() in a L() function, this changes the String() object to a std::string object that is known to Lua as an object that has a string inside it.

Forgot to say: very nice panel! Congrats!
Keep the good work!
On my side, I’m now finishing the Pro 2 panel and will soon release it for testing (busy with the logic of the Load/Save on main panel and the librarian manipulations).
Best regards!

[iceleben]

Thx so much Goodweather,
I tried to declare the Modulators in a called when the Panel has finished loading method but then I stumbled in the same Problems you had, tried the timer but still ist Buggy so for now I dropped it, if I see in your Panel how you managed that I’ll implement that as well 😉
While you are at the librarian manipulater – maybe you can help me again with something,again with the UiList Box. If I want to change the text from an UIListBox row (e.g. the one being clicked) with something I typed in a Ui Label what would be the Best way to do that? And is it possible to just Show 8 entries from an UiListBox that contains more then that?
Cant await your Panel and as well the new Manual, without you I think I had allready given up..

for the 2nd question I found a solution:
newwritetest=function(–[[ CtrlrModulator –]] modulator, –[[ number –]] value)

xvx=L(panel:getListBox(“FactoryBank1”):getTextForValue(0))
xvy=L(panel:getListBox(“FactoryBank1”):getTextForValue(1))
xvz=L(panel:getListBox(“FactoryBank1″):getTextForValue(2))
xtext=tostring(xvx..”\n”..xvy..”\n”..xvz)
panel:getComponent(“FactoryBank1old”):setPropertyString (“uiListBoxContent”,xtext)
end
works, but I´m sure you have a better one 🙂 Still stuck with the first question

Well, not sure I follow you…
Q1: to replace the content of one line, there are different approaches depending on other possibilities of your panel.
On the Pro 2, I implemented a librarian and I can manage full banks or single programs belonging to banks. I took a lazy but easy approach to replace one line: I rebuilt the whole listbox content based on the new content of the bank.
Each bank contains 99 programs having the same 1178 bytes structure. This is stored in a Memoryblock and I know precisely where to find the name of each program.
So it is simply a matter to have a loop reading the 99 names and putting them after each other separated by \n

lbDisk1:setPropertyString ("uiListBoxContent", RefreshBankListBox(mbDisk1))

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

trim is not a standard function. DSI data is packed so before reading the name I must first unpack the data and hopefully Atom provided a function in Ctrlr to do it.

Another approach is to search for the n-1 and n “\n”, cut your string (string.sub()) and add your new string in between. I tested this and it works fine.
Look at http://www.lua.org/manual/5.1/manual.html#5.4 for string manipulation and use Google for searching for code examples. Don’t take complex code. Often not needed.

Q2: show only 8 names? Do you mean you have a bank of 100 names for example but for some reason you want only to show 8 of them? Well, you can either make a loop and search for the 8th “\n” then take the part of the string until that position or you can rebuild from 1 to 8.
Lua is strong in string manipulation.
I often test small piece of code at http://www.lua.org/demo.html.
Use “print(some_value)” to see some output.

You will learn a lot by reading (take a lot of time) the end of the .cpp files in https://sourceforge.net/p/ctrlrv4/code/HEAD/tree/nightly/Source/Lua/ and in the different folders including in the parent one.
Also by reading things in the Juce API at https://www.juce.com/doc/classes
and in the forum, the different panels made by users and the DEMO panels provided by Atom.
You can also open the Lua console and type in the bottom part what(some_object or variable) to see all functions it can have.
Try with your listbox! what(FactoryBank1)

I add also issues myself in many things but then left it for a few days then came back, read a bit everywhere and solved the issues or found some workaround.

[iceleben]

Got it:
newwritetest=function(–[[ CtrlrModulator –]] modulator, –[[ number –]] value)

textable={}
xvt=panel:getComponent(“RenameTxt2”):getProperty(“uiLabelText”)
xvn=panel:getListBox(“FactoryBank1”):getLastRowSelected()+1

xv0=L(panel:getListBox(“FactoryBank1”):getTextForValue(0)) textable[1]=xv0
xv1=L(panel:getListBox(“FactoryBank1”):getTextForValue(1)) textable[2]=xv1
xv2=L(panel:getListBox(“FactoryBank1”):getTextForValue(2)) textable[3]=xv2
xv3=L(panel:getListBox(“FactoryBank1”):getTextForValue(3)) textable[4]=xv3
xv4=L(panel:getListBox(“FactoryBank1”):getTextForValue(4)) textable[5]=xv4
xv5=L(panel:getListBox(“FactoryBank1”):getTextForValue(5)) textable[6]=xv5
xv6=L(panel:getListBox(“FactoryBank1”):getTextForValue(6)) textable[7]=xv6
xv7=L(panel:getListBox(“FactoryBank1″):getTextForValue(7)) textable[8]=xv7

textable[xvn]=xvt
TestDat=table.concat(textable,” “..”\n”,1,8)

xvtest=console(tostring(TestDat))

panel:getComponent(“FactoryBank1old”):setPropertyString (“uiListBoxContent”,TestDat)
end

oh I see you replied…have to read that
the MKS doesnt have any Tone or patchnames at all( I’m lucky I can skip that part :))but I thought it’ll be nice to have some reference in the Panel
the MKS also works with 8 Banks with 8 tones and patches each thats why I went for 8 first..
