ListHeader::getSortSegment Exception

[TheBren]

I'm getting an exception when I try to add an item to a MultiColumnList:

ListHeader::getSortSegment - Sort segment was NULL! (No segments are attached to the ListHeader?)

It happens when I call MultiColumnList::insertRow().

I tried calling MultiColumnList::setSortColumn(0), same error.

I have no idea what I'm doing really. Just sorta feeling my way along. Are there any docs or samples for MultiColumnList? Anyone have any suggestions?

Thanks!

Here's what I do. First, set up your columns:

Code: Select all

float fTotalWidth = 0.99f;
float fDivider = 0.70f;
m_pSettings->addColumn("Setting", COLUMN_NAME, fDivider);
m_pSettings->addColumn("Value", COLUMN_VALUE, (fTotalWidth-fDivider));
m_pSettings->setSelectionMode(CEGUI::MultiColumnList::RowSingle);


Then, add your elements:

Code: Select all

void AddSetting(int a_iIndex, const utf8* a_szName, const utf8* a_szValue, bool a_bChangedColour)
{
  uint32 iRow = m_pSettings->addRow();
   
  static uint32 s_iNormalColour = MakeXRGB(200, 200, 200);
  static uint32 s_iChangedColour = MakeXRGB(200, 255, 255);
   
  CEGUI::ListboxTextItem* pName = ANew_Gui CEGUI::ListboxTextItem(a_szName, a_iIndex);
  pName->setSelectionBrushImage("TaharezLook", "ListboxSelectionBrush");
  pName->setTextColours(CEGUI::colour(s_iNormalColour));
  m_pSettings->setItem(pName, COLUMN_NAME, iRow);
   
  CEGUI::ListboxTextItem* pValue = ANew_Gui CEGUI::ListboxTextItem(a_szValue, a_iIndex);
  pValue->setSelectionBrushImage("TaharezLook", "ListboxSelectionBrush");
  pValue->setTextColours(CEGUI::colour(a_bChangedColour ? s_iChangedColour : s_iNormalColour));
  m_pSettings->setItem(pValue, COLUMN_VALUE, iRow);
}

I was using CELayoutEditor to create the parent MultiColumnList and then trying to add the headers/list to the XML manually. I should probably have mentioned this.

So now I have the MultiColumnList in XML and add the columns through code as you suggested, and it works fine. Thanks!

How do I apply my own scheme? It appears to be using WindowsLook by default.
