[Help] I'm a little stumped here...

I am having trouble getting some combo boxes to work.

The problem is that the ListBoxTextItems are not being added to the damn combo boxes! I click the right side (the drop down arrow) of the top combo box (the only one I'm working with right now), and nothing happens. If I set the combo box to readonly=false, I can type in the combo box... hovering over the drop down arrow makes it light up... so internal events are working and reacting to keyboard and mouse stuff...

So why aren't these items being added to the list?

Posted below is the code, so feel free to take a look and tell me what I may be doing wrong.

The code has been messed around with a lot, so it's not all that optimized, so forgive me for that.

The window itself looks like this when it's created and shown:



(the font is too big, but ignore that)

The combo boxes are to the right of their labels as you can see.

Private WithEvents cmbDisciplines As Combobox
Private WithEvents cmbSkills As Combobox

''' I will redim those zero arrays as needed

cmbClasses = WM.CreateCombobox(Combobox, Name)
cmbClasses.SetSize(cbSize)
cmbClasses.setReadOnly(True)
cmbClasses.SetPosition(rAlign, Y)
cmbClasses.SubscribeEvents()
''' Mywindow = the skills window...
MyWindow.AddChildWindow(cmbClasses)

lbiClasses(0) = New ListboxTextItem("Common", Convert.ToUInt32(VermundData.Vermund.Data.Classes.Common), IntPtr.Zero, False, False)
cmbClasses.addItem(lbiClasses(0))
lbiClasses(1) = New ListboxTextItem("Elementalist", Convert.ToUInt32(VermundData.Vermund.Data.Classes.Elementalist), IntPtr.Zero, False, False)
cmbClasses.addItem(lbiClasses(1))
lbiClasses(2) = New ListboxTextItem("Rogue", Convert.ToUInt32(VermundData.Vermund.Data.Classes.Rogue), IntPtr.Zero, False, True)
cmbClasses.addItem(lbiClasses(2))
lbiClasses(3) = New ListboxTextItem("Scholar", Convert.ToUInt32(VermundData.Vermund.Data.Classes.Scholar), IntPtr.Zero, False, True)
cmbClasses.addItem(lbiClasses(3))
lbiClasses(4) = New ListboxTextItem("Warrior", Convert.ToUInt32(VermundData.Vermund.Data.Classes.Warrior), IntPtr.Zero, False, True)
cmbClasses.addItem(lbiClasses(4))
lbiClasses(5) = New ListboxTextItem("Worker", Convert.ToUInt32(VermundData.Vermund.Data.Classes.Worker), IntPtr.Zero, False, True)
cmbClasses.addItem(lbiClasses(5))


That's about it... I only pasted the stuff relevant to the top combo box...

FYI: I have WM set equal to WindowManager as sort of an alias...

This code works for me:


class CEGUIApplication : ExampleApplication
{
protected OgreCEGUIRenderer mGuiRenderer = null;
protected GuiSystem mGuiSystem = null;
protected Window mBackgroundWindow = null;
protected Window mEditorWindow = null;
protected PushButton mQuitButton = null;
protected Editbox mEditbox = null;
protected Log mLog = null;
protected Combobox mComboBox = null;
protected ListboxTextItem mListboxTextItem1 = null;
protected ListboxTextItem mListboxTextItem2 = null;

protected override void CreateScene()
{
mLog = LogManager.Singleton.createLog("DemoCEGUI.log", false, false );
mLog.LogMessage("My new Log. Hells yeah!");

base.mSceneManager.AmbientLight = Color.FromArgb(125,125,125,125);
base.mSceneManager.SetSkyDome(true, "Examples/CloudySky", 5, 8);

mGuiRenderer = new OgreCEGUIRenderer( base.mRenderWindow );
mGuiRenderer.Initialise();
mGuiSystem = new GuiSystem(mGuiRenderer);

Logger.Instance.setLoggingLevel(LoggingLevel.Insane);

SchemeManager.Instance.LoadScheme("TaharezLook.scheme");
mGuiSystem.SetDefaultMouseCursor("TaharezLook", "MouseArrow");
mGuiSystem.DefaultFontName = "Tahoma-12";

mBackgroundWindow = WindowManager.Instance.CreateWindow("DefaultWindow", "BackgroundWindow");
mGuiSystem.GUISheet = mBackgroundWindow;

mEditorWindow = WindowManager.Instance.CreateWindow("TaharezLook/FrameWindow", "TestWindow");
mBackgroundWindow.AddChildWindow( mEditorWindow );
mEditorWindow.SetSize(0.9f, 0.9f);
mEditorWindow.SetPosition(0.05f, 0.05f);
mEditorWindow.Text = "CeguiDotNet Demo";
mEditorWindow.SubscribeEvents();

mQuitButton = WindowManager.Instance.CreatePushButton("TaharezLook/Button", "QuitButton");
mQuitButton.Text = "Quit";
mQuitButton.SetPosition(0.1f,0.1f);
mQuitButton.SetSize(0.8f,0.2f);
mQuitButton.SubscribeEvents();
mQuitButton.Clicked += new WindowEventDelegate(QuitClicked);
mEditorWindow.AddChildWindow(mQuitButton);

mEditbox = WindowManager.Instance.CreateEditbox("TaharezLook/Editbox", "Editbox");
mEditbox.Text = "Editbox";
mEditbox.SetPosition(0.1f, 0.4f);
mEditbox.SetSize(0.8f, 0.2f);
mEditbox.setReadOnly(false);
mEditbox.SubscribeEvents();
mEditorWindow.AddChildWindow(mEditbox);

mComboBox = WindowManager.Instance.CreateCombobox("TaharezLook/Combobox", "Combobox");
mComboBox.SetPosition(0.1f,0.6f);
mComboBox.SetSize(0.8f,0.2f);

mListboxTextItem1 = new ListboxTextItem("One",0,IntPtr.Zero,false,false);
mComboBox.addItem(mListboxTextItem1);

mListboxTextItem2 = new ListboxTextItem("Two",1,IntPtr.Zero,false,false);
mComboBox.addItem(mListboxTextItem2);

mComboBox.SubscribeEvents();
mEditorWindow.AddChildWindow(mComboBox);

mEditorWindow.Show();
}


Try incresing the height of the combobox (http://www.ogre3d.org/phpBB2/viewtopic.php?t=11074&highlight=listboxtextitem

are the indexes correct 0, 1, 2... 5 ?
add code to log the Convert.ToUInt32(VermundData.Vermund.Data.Classes.Common) and so on.

I'll try your suggestions, thanks.

Okay, that's the key right there.

The "height" of the box is the height of the entire thing, drop-down area included.

So I had it set to be the height of just the top part, so there was no room to drop down. I set it to a .8 relative height of the window, and sure 'nuff, it was .8 of the entire window when dropped down, but the TOP part was still the same size...

Undocumented feature I suppose...

I would think there would be a base height, and a drop-down list height... or you could set the drop down list to auto-resize based on the number of entries.

What I did was I created a small function to do approximately that:

Private Function ResizeBox(ByRef Mybox As Combobox)
If Convert.ToSingle(Mybox.getItemCount) < 8 Then
Mybox.setHeight(Convert.ToSingle(cmbClasses.getItemCount) * 0.1)
Else
Mybox.setHeight(0.8)
End If
End Function
