Getting The Selected Item from a Combo

[Godlike-Productions]

Strangely I couldn't find this one over at the old forums. Lots of stuff on setting them, but nothing on getting the value.

panel:getCombo("upperProgramCombo"):getSelectedId()

Does this work?

comboId = panel:getcombo(name):getSelectedId()

If comboId == 0 then
-- do something
end

Or you have to use getSelectedItemIndex, can't remember.

That will work.

This is my entire method.

I'm not sure if there is an index method as well, because Id is essentially Index.

updatePatchName = function(--[[ CtrlrModulator --]] mod, --[[ number --]] value, --[[ number --]] source)

    local patchSelected = panel:getCombo("upperProgramCombo"):getSelectedId()
    patchNameLabel:getComponent():setPropertyString ("uiLabelText", jupiterBank[patchSelected].name)

end

But these are they!

[Ted-juh]

int getSelectedId();
int getSelectedItemIndex();
void setSelectedId(const int id, const bool dontNotify);
void setSelectedItemIndex(const int index, const bool dontNotify);

From the comboBox.h file.

Here are a few functions I use:

function returnComboSelectedItemIndex(myCombo)
	-- Your method code here
    local c = panel:getComboComponent(myCombo)
        local combo = c:getOwnedComboBox()
return combo:getSelectedItemIndex()
end

function returnComboElementCount(myCombo)
	-- Your method code here
return panel:getModulatorByName(myCombo):getProperty("modulatorMax")
end

function returnSelectedPatchNameFromCombo(myCombo)
	-- Your method code here
    local c = panel:getComboComponent(myCombo)
        local combo = c:getOwnedComboBox()
            return combo:getText() 
end

Also Atom gives some good examples of multi level combos in the DEMO - popup menu panel, which comes with ctrlr

As usual, the full list of capabilities can be found in the Juce API.
Look at: https://docs.juce.com/master/classComboBox.html
But this is also a full model and you need to check what has been ported to Ctrlr by testing the different methods/functions.

I still get confused with the c++ coding from Juce.

I can never remember if comboBox::getSelectedId() ends up as comboBox.getSelectedId or comboBox:getSelectedId, and where we end up with brackets etc in LUA, though this is more due to my lack of knowledge, than a lack of documentation.

My search strategy is

Is there an example in ctrlr?
Is there an example in LUA? Yes - will it work in 5.1? Does it rely on a module like LuaJIT?
Is it documented in Juce?
