Get current value of combobox

Hi,
I'm trying to retreive the index of the selected item in a combobox. However I cannot find this function in the API reference. Is there something like "simUI.getComboboxSelectedIndex" available?
Workaround I currently use is registering change events, but this is cumbersome.

You can use simUI.getComboboxSelectedIndex to get the selected index, and simUI.getComboboxItemText to get the text at that index.
simUI.getComboboxSelectedIndex has been added on 5th June, so it may not be contained in the V-REP release.
Use the git repository

Good to know the function is available. I prefer to use the official releases (so customers can download the tried and tested player).
Do you know when the next release is scheduled?

I have no idea about the date of next release, sorry.
If you want your code to work without the simUI.getComboboxSelectedIndex, you should use the "on-change" attribute of the combobox element, and store the new index in the event handler:
Code: Select all
function combo_changed(ui,id,idx)
combo_index=idx
end
function button_click(ui,id)
sim.addStatusbarMessage('combobox index: '..combo_index)
end
function sysCall_init()
combo_index=0
ui=simUI.create([[<ui>
<combobox on-change="combo_changed">
<item>one</item>
<item>two</item>
<item>three</item>
</combobox>
<button on-click="button_click" text="Click me" />
</ui>]])
end

Thanks for your support; this is the method that I was using.
Maybe someone from Coppelia can tell us more about the release schedule?

Happy to see that simUI.getComboboxSelectedIndex is available in v3.6.0! (just a note: the online documentation does not mention the function)
