NSTableColumn objects represent columns in
|
|
NSTableViews.

|
<h3><a name ="cont-1">The Column Identifier</a></h3>
|
|
<p>
|
|
|
|
Each NSTableColumn object is identified by an object,
|
|
called the column identifier. The reason is that,
|
|
after a column has been added to a table view, the user
|
|
might move the columns around, so there is a need to
|
|
identify the columns regardless of their position in
|
|
the table.
|
|
</p>
|
|
<p>
|
|
|
|
The identifier is typically a string describing the
|
|
column. This identifier object is never displayed to
|
|
the user ! It is only used internally by the program to
|
|
identify the column - so yes, you may use a funny
|
|
string for it and nobody will know, except people
|
|
reading the code.
|
|
</p>
|
|
<h3><a name ="cont-2">
|
|
Information Stored in an NSTableColumn Object
|
|
</a></h3>
|
|
<p>
|
|
|
|
An NSTableColumn object mainly keeps information about the
|
|
width of the column, its minimum and maximum width;
|
|
whether the column can be edited or resized; and the
|
|
cells used to draw the column header and the data in
|
|
the column. You can change all these attributes of the
|
|
column by calling the appropriate methods. Please note
|
|
that the table column does not hold nor has access to
|
|
the data to be displayed in the column; this data is
|
|
maintained in the table view's data source, as
|
|
described in the NSTableView documentation. A last
|
|
hint: to set the title of a table column, ask the table
|
|
column for its header cell, and set the string value
|
|
of this header cell to the desired title.
