DlgListBox.GetSelected return only the last selected item

[Olivier Chivet]

Hi all,

First I'm new with TrueUpdate and LUA language.

I just downloaded the TrueUpdate 3.0 Trial version and try to use a ListBox in a dialog.
So I added a DlgListBox from the screen gallery in the wizard, changed the Style to "Checklist Box" and checked the "Multi select" option.
In the "On Next" action tab, I just want to display (for debug checking) the name of all selected items.

To do this, I added this code :
--------------------------------------
local Selected = DlgListBox.GetSelected(CTRL_LIST_BOX);
local index;
local value;

for index,value in Selected do
Dialog.Message( "Selection ", index..value, MB_OK, MB_ICONINFORMATION, MB_DEFBUTTON1);
end
--------------------------------------
Even if I selected more than one Item, the GetSelected function always returned only the last item I selected.
Moreover, If I display the existing variable "nSelectedCount" (result of "DlgListBox.GetSelectedCount") it always display "1".

Could someone help me to obtain the complete list of selected items ?

Thanks a lot.

Hello,

DlgListBox.GetSelected returns a table only if the ListBox is not set to Checklist Box. See this instead:


for i = 1, DlgListBox.GetCount(CTRL_LIST_BOX) do
tProperties = DlgListBox.GetItemProperties(CTRL_LIST_BOX, i);
if (tProperties.Checked) then
Dialog.Message( "Selection ", i .."=" .. tProperties.Text, MB_OK, MB_ICONINFORMATION, MB_DEFBUTTON1);
end
end

Hello upeters,

Thank you for your code, It works fine.

And sorry for my misunderstanding between "(Get)Selected" and "Checked".

It's not completly true. You can select more than one line in a ListBox with "Multi Select" option even if it has the "CheckList Box" style. Then the "GetSelected" function returns the correct list of item, checked or not.

Best regards.
