## Detailed Description

Adds methods to set the column attributes to wxHeaderColumn.

This class adds setters for the column attributes defined by wxHeaderColumn. It is still an abstract base class and needs to be implemented before using it with wxHeaderCtrl.

## Member Function Documentation

void wxSettableHeaderColumn::ChangeFlag | ( | int | flag,
|  | bool | set
| ) |  |

Set or clear the given flag.

Parameters

  flag | The flag to set or clear.
  set | If true, set the flag, i.e. equivalent to calling SetFlag(), otherwise clear it, as ClearFlag().

See also
  SetFlags()

void wxSettableHeaderColumn::ClearFlag | ( | int | flag | ) |

Clear the specified flag for the column.

See also
  SetFlags()

virtual void wxSettableHeaderColumn::SetAlignment | ( | wxAlignment | align | ) |

pure virtual

Set the alignment of the column header.

Parameters

  align | The text alignment in horizontal direction only or wxALIGN_NOT to use the default alignment, The possible values here are wxALIGN_CENTRE, wxALIGN_LEFT or wxALIGN_RIGHT with wxALIGN_CENTRE_HORIZONTAL being also supported as synonym for wxALIGN_CENTRE for consistency (but notice that GetAlignment() never returns it).

Implemented in wxHeaderColumnSimple.

virtual void wxSettableHeaderColumn::SetBitmap | ( | const wxBitmap & | bitmap | ) |

pure virtual

Set the bitmap to be displayed in the column header.

Notice that the bitmaps displayed in different columns of the same control must all be of the same size.

Implemented in wxHeaderColumnSimple.

void wxSettableHeaderColumn::SetFlag | ( | int | flag | ) |

Set the specified flag for the column.

See also
  SetFlags()

virtual void wxSettableHeaderColumn::SetFlags | ( | int | flags | ) |

pure virtual

Set the column flags.

This method allows setting all flags at once, see also generic ChangeFlag(), SetFlag(), ClearFlag() and ToggleFlag() methods below as well as specific SetResizeable(), SetSortable(), SetReorderable() and SetHidden() ones.

Parameters

  flags | Combination of wxCOL_RESIZABLE, wxCOL_SORTABLE, wxCOL_REORDERABLE and wxCOL_HIDDEN bit flags.

Implemented in wxHeaderColumnSimple.

virtual void wxSettableHeaderColumn::SetHidden | ( | bool | hidden | ) |

virtual

Hide or show the column.

By default all columns are shown but some of them can be completely hidden from view by calling this function.

Equivalent to ChangeFlag(wxCOL_HIDDEN, hidden).

virtual void wxSettableHeaderColumn::SetMinWidth | ( | int | minWidth | ) |

pure virtual

Set the minimal column width.

This method can be used with resizable columns (i.e. those for which wxCOL_RESIZABLE flag is set in GetFlags() or, alternatively, IsResizeable() returns true) to prevent the user from making them narrower than the given width.

Parameters

  minWidth | The minimal column width in pixels, may be 0 to remove any previously set restrictions.

Implemented in wxHeaderColumnSimple.

virtual void wxSettableHeaderColumn::SetReorderable | ( | bool | reorderable | ) |

virtual

Allow changing the column order by dragging it.

Equivalent to ChangeFlag(wxCOL_REORDERABLE, reorderable).

virtual void wxSettableHeaderColumn::SetResizeable | ( | bool | resizable | ) |

virtual

Call this to enable or disable interactive resizing of the column by the user.

By default, the columns are resizable.

Equivalent to ChangeFlag(wxCOL_RESIZABLE, resizable).

virtual void wxSettableHeaderColumn::SetSortable | ( | bool | sortable | ) |

virtual

Allow clicking the column to sort the control contents by the field in this column.

By default, the columns are not sortable so you need to explicitly call this function to allow sorting by the field corresponding to this column.

Equivalent to ChangeFlag(wxCOL_SORTABLE, sortable).

virtual void wxSettableHeaderColumn::SetSortOrder | ( | bool | ascending | ) |

pure virtual

Sets this column as the sort key for the associated control.

This function indicates that this column is currently used for sorting the control and also sets the sorting direction. Notice that actual sorting is only done in the control associated with the header, this function doesn't do any sorting on its own.

Don't confuse this function with SetSortable() which should be used to indicate that the column may be used for sorting while this one is used to indicate that it currently is used for sorting. Of course, SetSortOrder() can be only called for sortable columns.

Parameters

  ascending | If true, sort in ascending order, otherwise in descending order.

Implemented in wxHeaderColumnSimple.

virtual void wxSettableHeaderColumn::SetTitle | ( | const wxString & | title | ) |

pure virtual

Set the text to display in the column header.

Implemented in wxHeaderColumnSimple.

virtual void wxSettableHeaderColumn::SetWidth | ( | int | width | ) |

pure virtual

Set the column width.

Parameters

  width | The column width in pixels or the special wxCOL_WIDTH_DEFAULT (meaning to use default width) or wxCOL_WIDTH_AUTOSIZE (size to fit the content) value.

Implemented in wxHeaderColumnSimple.

void wxSettableHeaderColumn::ToggleFlag | ( | int | flag | ) |

Toggle the specified flag for the column.

If the flag is currently set, equivalent to ClearFlag(), otherwise – to SetFlag().

See also
  SetFlags()

void wxSettableHeaderColumn::ToggleSortOrder | ( |  | ) |

Inverses the sort order.

This function is typically called when the user clicks on a column used for sorting to change sort order from ascending to descending or vice versa.

See also
  SetSortOrder(), IsSortOrderAscending()

void wxSettableHeaderColumn::UnsetAsSortKey | ( |  | ) |

Don't use this column for sorting.

This is the reverse of SetSortOrder() and is called to indicate that this column is not used for sorting any longer.
