How to display the headers of the ListBox?

[Anonymous]

In my ListBox, it has Three headers.

DGListSetHeaderItemCount(dialId, item, 3);
DGListSetHeaderFlags(dialId, item, true, false, false);
DGListSetHeaderItemFlags(dialId, item, 1, DG_IS_CENTER|DG_IS_TRUNCMIDDLE, false);
DGListSetHeaderItemText(dialId, item, 1, "ID");

DGListSetHeaderItemFlags(dialId, item, 2, DG_IS_CENTER|DG_IS_TRUNCMIDDLE, false);
DGListSetHeaderItemText(dialId, item, 2, "Length");

DGListSetHeaderItemFlags(dialId, item, 3, DG_IS_CENTER|DG_IS_TRUNCMIDDLE, false);
DGListSetHeaderItemText(dialId, item, 3, "Has");

But They can not display all.

Why??

You have to set the header item size as well with DGListSetHeaderItemSize.

Hope this helps,

When creating class-based list box with header, the list box is not created. Also when HasHeader() is called, it will return false whether headerFlag is set to Header or NoHeader.

SingleSelListBox (
    const Panel &       panel,
    const Rect &        rect,
    ScrollType          scroll = VScroll,
    PartialItemType     part = PartialItems,
    HeaderFlag          headerFlag = NoHeader,   <------------------
    short               headerSize = 0
);

MultiSelListBox (
    const Panel &       panel,
    const Rect &        rect,
    ScrollType          scroll = VScroll,
    PartialItemType     part = PartialItems,
    HeaderFlag          headerFlag = NoHeader,   <------------------
    short               headerSize = 0);
