layout loding problem

[Ninja]

Hi Guys

been experimenting with loading a window with the xml way

i have a push button that calls

Code: Select all

bool HandleButtonSetUp(const CEGUI::EventArgs& e)
{
   Window* Menu = WindowManager::getSingletonPtr()->loadWindowLayout("art/Setup/SetUp.xml");
   
   return true;   
}

at first press this inserts into the cegui log

(InfL1) ---- Successfully completed loading of GUI layout from 'art/Setup/SetUp.xml' ----

but no window appears on screen if i press the button a 2nd time i get an error and in cegui log

Error) Exception: WindowManager::createWindow - A Window object with the name 'SetUP' already exists within the system.
05/09/2006 19:06:04 (Error) Exception: GUILayout_xmlHandler::startElement - layout loading has been aborted since Window named 'SetUP' already exists.
05/09/2006 19:06:04 (Error) WindowManager::loadWindowLayout - loading of layout from file 'art/Setup/SetUp.xml' failed.

the xml file has only this in

Code: Select all

<?xml version="1.0" ?>
<GUILayout>
            <Window Type="TaharezLook/FrameWindow" Name="SetUP">
            <Property Name="RelativeMinSize" Value="w:320 h:320" />
            <Property Name="RelativeMaxSize" Value="w:320 h:320" />
            <Property Name="Position" Value="x:0 y:0" />
            <Property Name="Size" Value="w:320 h:320" />
            <Property Name="Text" Value="Test Window" />
            <Property Name="CloseButtonEnabled" Value="true" />
            <Property Name="FrameEnabled" Value="true" />
          </Window>
</GUILayout>

where did i go wrong please

TIA

From Widget Galore

Code: Select all

// Retrieve the window manager
WindowManager& winMgr = WindowManager::getSingleton();

// Load the TaharezLook scheme and set up the default mouse cursor and font
SchemeManager::getSingleton().loadScheme("TaharezLookSkin.scheme");
System::getSingleton().setDefaultMouseCursor("TaharezLook", "MouseArrow");
FontManager::getSingleton().createFont("Commonwealth-10.font");

// Set the GUI Sheet
Window* sheet = winMgr.createWindow("DefaultWindow", "root_wnd");
System::getSingleton().setGUISheet(sheet);

// Load a layout
Window* guiLayout = winMgr.loadWindowLayout("WidgetGalore.layout");
sheet->addChildWindow(guiLayout);


You're probably missing the GUI sheet creation and the call to sheet->addChildWindow(guiLayout)

The first call to loadWindowLayout creates the window but since you do not attach it to the sheet it is not displayed. Pressing the button once more attempts to reload the layout but since it is already loaded you receive the duplicate names error.

heya

Thanks for the reply this opens a new window but loses the original window that has the background and buttons on it

what i'am attempting to do is have a child window open on top the main window if possible

ie have the main ui with buttons bg image then on button press this opens the window from the .layout file on top of the main screen

also how would you use the CloseButtonEnabled function using this way

TIA

Hi Ninja,

if you have a pointer to your main window, just say "MainWindow->AddChildwindow(Menu);" Changing the GuiSheet indeed removes all current windows (at least visually).

For closing, use the RemoveChildWindow method the same way.

About the other question in your first reply: window names must be unique. You can do multiple loadings of one layout by using the second parameter to give a prefix.

Good luck!

heya
thanks for all the patiance with me n00b showing i guess

ok from my button press i call

Code: Select all

bool HandleButtonSetUp(const CEGUI::EventArgs& e)
{   
   using namespace CEGUI;
   // Retrieve the window manager
WindowManager& winMgr = WindowManager::getSingleton();

// Set the GUI Sheet
Window* child = winMgr.createWindow("DefaultWindow", "Setup_wnd");
System::getSingleton().setGUISheet(child);

// Load a layout
Window* setup = winMgr.loadWindowLayout("art/Setup/SetUp.layout");
child->addChildWindow(setup);

   return true;   
}

this works ok but as i said loads a new window and removes the main one
where all i need it to is load

Code: Select all

<?xml version="1.0" ?>
<GUILayout>
           <Window Type="DefaultWindow" Name="setup_wnd">

        <Window Type="TaharezLook/FrameWindow" Name="testwindow">
            <Property Name="RelativeMinSize" Value="w:0.2 h:0.2" />
            <Property Name="RelativeMaxSize" Value="w:0.8 h:0.8" />
            <Property Name="Position" Value="x:0.2 y:0.2" />
            <Property Name="Size" Value="w:0.5 h:0.5" />
            <Property Name="Text" Value="Test Window" />
            <Property Name="CloseButtonEnabled" Value="True"  />
        </Window>
    </Window>
</GUILayout>

over the top if i hardcode the window this works fine with it being visable on load up (not ideal) but i have the closebuttonenabled working via the

Code: Select all

textwnd->subscribeEvent(FrameWindow::EventCloseClicked, Event::Subscriber(handleCloseButton));

which pulls

Code: Select all

bool handleCloseButton(const CEGUI::EventArgs& e)
{
static_cast<const CEGUI::WindowEventArgs&>(e).window->hide();    
   return true;
}

but cant seem to get this working with the layout way

TIA

From my own code. When initializing the game I create the sheet:

Code: Select all

CEGUI::WindowManager& winMgr = CEGUI::WindowManager::getSingleton();
Window* guiSheet = winMgr.createWindow("DefaultWindow", "guiSheet");
CEGUI::System::getSingleton().setGUISheet(guiSheet);


Afterward I pre-load multiple windows onto that existing sheet, which you could do from your button:

Code: Select all

CEGUI::Window* chatBox = winMgr.loadWindowLayout("ChatBox.layout");
guiSheet->addChildWindow(chatBox);

CEGUI::Window* cargo = winMgr.loadWindowLayout("Cargo.layout");
guiSheet->addChildWindow(cargo);

CEGUI::Window* merchant = winMgr.loadWindowLayout("Merchant.layout");
guiSheet->addChildWindow(merchant);


The problem could be that you have a sheet for your buttons and when you press on the setup button you use a new sheet whereas you seem to want to reuse the same sheet.
