help with listbox's

[orion]

Hi All

been trying to sort this out for a while and if i had hair to loose yup its gone

so i did work in v7 of cegui and porting it over to v8 ran into a prob what i'am trying to do is fill a listbox from a .ini file
if i step though the code i get the description form the ini file just fine but nothing appears in the item listbox and i mean nothing nada cilch
used to be ok with .getWindow old way i know so i'm pretty sure it has to with the tlist part but unsure what it is
"LIST" is the itemlistbox name in the book.layout file
anyways here the code any help kindly recived

Code: Select all

CEGUI::WindowManager& winMgr = CEGUI::WindowManager::getSingleton();
    CEGUI::FrameWindow* pb = static_cast<CEGUI::FrameWindow*>( winMgr.loadLayoutFromFile( "book.layout" ) );


   
    entry= Book->GetCurrentPtr();

    while ( entry )
    {
        CEGUI::ItemListbox* tlist = static_cast<CEGUI::ItemListbox*>(winMgr.createWindow("TaharezLook/ItemListbox", "LIST" ));
        pb->getChild("LIST");
        // create new list item
         CEGUI::ItemEntry* pitem = static_cast<CEGUI::ItemEntry*>(winMgr.createWindow("TaharezLook/ListboxItem"));

         
         tlist->addItem(pitem);
                 // set text on this item to whatever name's are in the ini file
        pitem->setText( entry->description );


       pitem->setSelected( true );

       tlist->invalidate();
        tlist->show();
    }

Have you looked at the sample code for comparison? There are many examples of Listbox usages afaik, and if it works there it must work for you too (or at least we can compare what's different and figure this out)

[orion]

Hi Ident,

thanks for getting back to me

indeed i have looked though the samples and threads here aswell and as far as i can tell it should be ok

i've set up some break points aswell and it says it is populating the listbox fine but just dont show anything at all same with editbox aswell btw

in code i set up the editbox like so

Code: Select all

CEGUI::WindowManager& winMgr = CEGUI::WindowManager::getSingleton();
    CEGUI::FrameWindow* bk = static_cast<CEGUI::FrameWindow*>(winMgr.loadLayoutFromFile("bk.layout"));
CEGUI::Editbox* con = static_cast<CEGUI::Editbox*>(bk->getChild("connection"));
con->setText("DOES THIS WORK");

but nada still empty box just like the listbox so i'm missing something here i'm sure of it
i've triued is Active and show but no go aswell

the layout gets loaded fine i.e i can see the framewindow and all the widgets

[Ident]

The looknfeel and scheme files are updated? Do editboxes ever work?

[orion]

ok so the way i understand now in 8.7 is

load the layout
then getChild is the widgets from the layout

Code: Select all

<Window type="TaharezLook/FrameWindow" name="bookwindow_" >

so child would be anything below that ?

soo at moment i have a button on the root that loads a framewindow this dispalys fine but then thats where my problems come in to play

should i be recalling

Code: Select all

 CEGUI::System::getSingleton().getDefaultGUIContext().getRootWindow()

[Ident]

Yes you attach your loaded layout to that root and then you modify it through that hierarchy. Does that help?

[orion]

Sort of yeah

i added that CEGUI::System::getSingleton().getDefaultGUIContext().getRootWindow()->getChild(bk);

but still no go here i can manually add text in all the editboxes when its dispalyed in UI so there all active ok but damn if i can see where i'm going wrong here with populating them with the code it's going to be something so stupid i can see it coming

[orion]

hmm just a quick one

CEGUI::ListboxTextItem* list_item

do i need to add this as a child of the listbox ?


just so you can see it should be populating the boxes



i alsotried con->notifyScreenAreaChanged(); but that didnt work :{

[Ident]

Have you run the samples and tried to copy over what they do piece by piece to eliminate the difference between what you do and what the sample does?

[orion]

how do you run the samples ?

i build CEGUI and all went fine but no where do i see for example demo6.exe or anything ?

i have just been looking though the .cpp files to help me this far

[orion]

ok so i started the code from fresh using the widgetDemo for refrence


code as it is now looks

Code: Select all

CEGUI::WindowManager& winMgr = CEGUI::WindowManager::getSingleton();
    CEGUI::FrameWindow* pk = static_cast<CEGUI::FrameWindow*>( winMgr.loadLayoutFromFile( "book.layout" ) );
   
    CEGUI::Listbox* list = dynamic_cast<CEGUI::Listbox*>(pk->getChild("LIST"));
   
       MyListItem* item = new MyListItem( "PLEASE WORK");
         // add this item to the listbox
         list->addItem(item);           

    list->isActive();
    list->show();
    list->notifyScreenAreaChanged();

and the class

Code: Select all

class MyListItem : public CEGUI::ListboxTextItem
{
public:
    MyListItem(const CEGUI::String& text, CEGUI::uint item_id = 0) :
        ListboxTextItem(text, item_id)
    {
        setSelectionBrushImage("TaharezLook/ListboxSelectionBrush");
    }
};

but still nothing shows

[Ident]

standard cmake config should build the samplebrowser, which contains all samples, run the samplebrowser and check out if things work there please.

it is really difficult to distant diagnose "doesnt work" "doesnt show" issues, i feel kind of blind here so far i could only point you to things you can investigate, now i suggest to check if it ever works at all and then compare from there. it is what i d do

[orion]

Yeah i understand the distance diagnosing problem appreciate the help thus far though

ok i can see the samplebrouser datafiles but in the bin directory i dont see the samplebrowser.exe i do have the sampleframework.exe ones but they complain of missing dll's which seems strange as i build the deps and cegui as per requirements and in right order so not sure on that one

thing is i'm porting the code over which makes it even harder as it used to work fine lol so i just have to understand what i doing wrong and slap myself when it gets resolved because i know its going to be something stupid on my end

[orion]

okay getting closer

i had to pass the framewindow diffrently from the button and it now loads the data into the listbox yippee

but gave me a new prob
when i add

Code: Select all

item->setSelected(true);

it sets both items to the select state bahhh and the next one is if i click on one of the items using

Code: Select all

list->subscribeEvent(CEGUI::ItemEntry::EventSelectionChanged,
       CEGUI::Event::Subscriber(&pk::Select, pb));

it dosnt pass the select state so that the select never passes to the

Code: Select all

select(item->getID(), pk);

part

Code: Select all

MyListItem* item = (MyListItem* )(( const CEGUI::WindowEventArgs& )args ).window;
        if ( item->isSelected() )
        {
           select(item->getID(), pk);
        }
