interface XGridColumnModel
Base Interfaces XGridColumnModel
┣ ::com::sun::star::lang ::XComponent
┣ ::com::sun::star::container ::XContainer
┗ ::com::sun::star::util ::XCloneable
::com::sun::star::lang ::XComponent
Description implements life time control for the component
::com::sun::star::container ::XContainer
Description allows to register listeners to be notified when columns are inserted or removed
::com::sun::star::util ::XCloneable
Description allows cloning the complete column model
Description An instance of this interface is used by the UnoControlGrid to
retrieve the column structure that is displayed in the actual control.
If you do not need your own model implementation, you can also use the DefaultGridColumnModel .
Since OOo 3.3
Methods' Details
getColumnCount
Description Returns the number of columns.
Returns the number of columns.
createColumn
Description creates a new column for use with the column model.
The newly created column is not yet inserted into the column container, you need to call addColumn
after you initialized the column object.
addColumn
Description Adds a column to the model.
You should use the createColumn member to create a new column. This gives
implementations of the XGridColumnModel interface the possibility to provide own column
implementations which extend the basic GridColumn type.
As soon as the column has been inserted into the model, the model takes ownership of it. This means when the
column is removed, or when the column model is disposed, the grid column is disposed as well.
Parameter column the column to add to the model.
Returns the index of new created column.
Throws ::com::sun::star::lang::IllegalArgumentException
if the given column is not a valid element for the column container, or if it is NULL .
removeColumn
Description removes a column from the model
The column object will be disposed upon removal.
Parameter ColumnIndex denotes the index of the column to remove
Throws ::com::sun::star::lang::IndexOutOfBoundsException
if ColumnIndex does not denote a valid column index.
getColumns
Description Returns all columns of the model.
Returns all columns associated with the model in a sequence of XGridColumn .
getColumn
Description Returns a specific column.
Parameter index the position of the requested column.
Returns the requested column.
setDefaultColumns
void
setDefaultColumns ([in] long
elements );
Description Fills the model with the given number of default columns
Existing columns will be removed before adding new columns. Listeners at the column model will
be notified one ::com::sun::star::container ::XContainerListener ::elementRemoved event
for each removed column, and one ::com::sun::star::container ::XContainerListener ::elementInserted
event for each insertion.
Parameter elements the number of default columns that should be set.
