[SOLVED]Listbox won't allow selection of multiple items

[DepletedCache]

Hello,

I have a project using CEGUI with OpenGL via SDL, running on Windows 7 Pro SP1 64-bit and using Visual Studio 2010 Ultimate.
Everything seems to be working fine except one odd issue I haven't had any luck in finding the answer to.

I have a Listbox that I want to be able to select multiple items from, however no matter what I have tried the Listbox will only have one Item selected at a time.
The Listbox is defined, as a child window of a root DefaultWindow, in an XML layout as the following:

Code: Select all

..
<Window Type="TaharezLook/Listbox" Name="TextureListbox" >
            <Property Name="Sort" Value="True" />
            <Property Name="AlwaysOnTop" Value="True" />
            <Property Name="MultiSelect" Value="True" />
            <Property Name="UnifiedAreaRect" Value="{{0.2,0},{0.2,0},{0.8,0},{0.8,0}}" />
</Window>
..


Notice that MultiSelect is set to True, and I have also checked during run-time, via the isMultiselectEnabled() method of the Listbox, that Multiselect is indeed enabled.

Here is the relevant code dealing with populating the Listbox:

Code: Select all

..
//Create the new ListboxItem with a given text(std::string texName) and a given ID(unsigned int indexID)
CEGUI::ListboxTextItem *newItem = new CEGUI::ListboxTextItem(texName, indexId);

//Set the selection overlay color to be green
newItem->setSelectionColours(CEGUI::colour(0.0, 1.0, 0.0, 0.5));

//Use the default TaharezLook Listbox Selection Brush Image
newItem->setSelectionBrushImage("TaharezLook", "ListboxSelectionBrush");

//Add the new item to the Listbox
listbox->addItem(newItem);


Here is my CEGUI.log, in its entirety:

Another thing to note is that I do have all the mouse/keyboard input being injected into CEGUI, which is evident by being able to click on and select/highlight an Item in the Listbox, type into an Editbox, click a Pushbutton, etc.

Any assistance is greatly appreciated.

[Jamarr]

A couple of things to check: did you subscribe any event handlers, and if so are they preventing multi-selection? are you injecting MouseUp events? are you sure you enabled multi-select on the correct listbox?

And just for curiosity sake, is there any particular reason why you choose /Listbox over /ItemListbox? The /Listbox widget is deprecated (we should really add a warning to the CEGUI log when using this), as it does not support window-based items; whereas /ItemListbox does.

Thank you for the reply.

I do have event handlers subscribed for some Pushbuttons, but not for the Listbox.
Both injectMouseButtonDown(..) and injectMouseButtonUp(..) are being appropriately called for the three mouse buttons (LeftButton, RightButton, MiddleButton).
Currently I only have this one Listbox in my project, so I am sure that multiselect is enabled on the correct Listbox.

And just for curiosity sake, is there any particular reason why you choose /Listbox over /ItemListbox? The /Listbox widget is deprecated (we should really add a warning to the CEGUI log when using this), as it does not support window-based items; whereas /ItemListbox does.

Interesting, I was unaware that Listbox was deprecated.
I just updated my code to use an ItemListbox and ItemEntrys instead, but still have the problem of only one item being able to be selected at a time.

Another oddity I just noticed after switching to ItemListbox from Listbox is that, after an initial call to getFirstSelectedItem(),
the first call to getNextSelectedItem() returns a pointer to the same item as getFirstSelectedItem() did, causing a single selected item to be processed twice,
unless I add some simple code to check for duplicates(which I did). When I was using Listbox, getFirstSelectedItem() and getNextSelected() worked together as expected though.
The code where this occurs:

Code: Select all

CEGUI::ItemListbox *listbox = static_cast<CEGUI::ItemListbox*>(CEGUI::WindowManager::getSingleton().getWindow("TextureListbox"));
CEGUI::ItemEntry *tmp = NULL;
CEGUI::ItemEntry *last = NULL;
CEGUI::ItemEntry *curItem = listbox->getFirstSelectedItem();
while(curItem != NULL)
{
   if(curItem != last)
   {
      if(map->removeTexture(curItem->getID()))
      {
         last = tmp = curItem;
         curItem = listbox->getNextSelectedItem();
         listbox->removeItem(tmp);
      }
   }
   else
      curItem = listbox->getNextSelectedItem();
}


Here is the updated definition in the XML layout(not much different):

Code: Select all

..
    <Window Type="TaharezLook/ItemListbox" Name="TextureListbox" >
                <Property Name="AlwaysOnTop" Value="True" />
                <Property Name="MultiSelect" Value="True" />
                <Property Name="UnifiedAreaRect" Value="{{0.2,0},{0.2,0},{0.8,0},{0.8,0}}" />
    </Window>
..


The updated code for populating the ItemListbox:

Code: Select all

CEGUI::ItemEntry *newItem = NULL;
..
newItem = static_cast<CEGUI::ItemEntry*>(CEGUI::WindowManager::getSingleton().createWindow("TaharezLook/ListboxItem", texName));
newItem->setText(texName);
newItem->setID(indexId);
newItem->setSelectable(true);

listbox->addItem(newItem);


The CEGUI.log hasn't changed at all after the transition.

Thanks again.

In hopes this might help identify the issue, I've uploaded a short video demonstrating it:

[Kulik]

Very strange, are you sure you are injecting CTRL properly? Does it work in other areas? It is possible that this has been broken, I will try to test it sometime soon.

[DepletedCache]

Well I feel foolish, that was exactly the issue.

For some reason, my SDL to CEGUI input mapping function was missing only the control and shift buttons.
I fixed that and sure enough I can select multiple items and the behavior is as expected.

I'll mark this thread solved, but I am still curious as to why the ItemListbox would return the same item twice when iterating through its selected list.
Now that I can select multiple items, I see that each item that gets selected is returned exactly twice when querying/stepping through the selected list using
getFirstSelectedItem() and getNextSelectedItem().

A big thank you to everyone who posted, your assistance was much appreciated.

Honestly I wonder how it works at all. To me it looks like this code would just return the same item over and over, so long as the item at d_nextSelectionIndex is already selected. I think findSelectedItem should set d_nextSelectionIndex = i + 1?

I just made that change, setting d_nextSelectionIndex to i+1 instead of just i, recompiled CEGUI and it does fix the issue of each selected item being returned twice.
However, it seems it must be incremented elsewhere, because that caused it to occasionally return only n-1 of n selected items.

Strange. Which of the selected items is it not returning? item-last-selected, last-selected-item, or something else?

If the built-in iteration approach is not working, you could just perform the iteration in client code using ItemListbox::isItemSelected(size_t index) and just iterate from index=0; note that I did not see a method for returning the number if items in the list, so you may need to track that manually. This is essentially what the built-in code does. However, It is a bit inefficient and scales poorly although it does get the job done. If efficiency is important you can always implement a custom-solution that tracks items as they are selected, avoiding the need to iterate the entire list later; and of course it would be nice if such a solution could be incorporated into the CEGUI code

I would at least suggest creating a mantis ticket and linking to this thread so that the CEGUI developers can look into fixing the issues with this class.
