IHeaderCtrl::GetColumnWidth method (mmc.h)

Retrieves the width, in pixels, of the column.

Syntax

HRESULT GetColumnWidth(
  [in]  int nCol,
  [out] int *pWidth
);

Parameters

[in] nCol

A zero-based index of the column from which the width is to be retrieved.

[out] pWidth

A pointer to width, in pixels, of the column. This parameter must not be NULL.

Return value

This method can return one of these values.

Remarks

This method can be called successfully even if items are already in the list.

If the column is currently hidden, GetColumnWidth returns 0 (zero) as the column width. However, because a column can have a (0) zero width without being hidden, a return value of (0) zero does not mean that the column is hidden. Therefore, the snap-in should call IColumnData::GetColumnConfigData to identify which columns are hidden.
