<div class="textblock"><p>Represents a column header in controls displaying tabular data such as <a class="el" href="classwx_data_view_ctrl.html" title="wxDataViewCtrl is a control to display data either in a tree like fashion or in a tabular form or bot...">wxDataViewCtrl</a> or <a class="el" href="classwx_grid.html" title="wxGrid and its related classes are used for displaying and editing tabular data.">wxGrid</a>. </p>
<p>Notice that this is an abstract base class which is implemented (usually using the information stored in the associated control) by the different controls using <a class="el" href="classwx_header_ctrl.html" title="wxHeaderCtrl is the control containing the column headings which is usually used for display of tabul...">wxHeaderCtrl</a>. As the control only needs to retrieve the information about the column, this class defines only the methods for accessing the various column properties but not for changing them as the setters might not be needed at all, e.g. if the column attributes can only be changed via the methods of the main associated control (this is the case for <a class="el" href="classwx_grid.html" title="wxGrid and its related classes are used for displaying and editing tabular data.">wxGrid</a> for example). If you do want to allow changing them directly using the column itself, you should inherit from <a class="el" href="classwx_settable_header_column.html" title="Adds methods to set the column attributes to wxHeaderColumn.">wxSettableHeaderColumn</a> instead of this class.</p>
<p>Finally, if you don't already store the column information at all anywhere, you should use the concrete <a class="el" href="classwx_header_column_simple.html" title="Simple container for the information about the column.">wxHeaderColumnSimple</a> class and <a class="el" href="classwx_header_ctrl_simple.html" title="wxHeaderCtrlSimple is a concrete header control which can be used directly, without inheriting from i...">wxHeaderCtrlSimple</a>.</p>
