    • Method Detail

      • getVisibleColumns

        public Object[] getVisibleColumns()

        Gets the array of visible column id:s, including generated columns.

        The columns are show in the order of their appearance in this array.

        Returns:

        an array of currently visible propertyIds and generated column ids.

      • setVisibleColumns

        public void setVisibleColumns​(Object... visibleColumns)

        Sets the array of visible column property id:s.

        The columns are show in the order of their appearance in this array.

        Parameters:

        visibleColumns - the Array of shown property id:s.

      • getColumnHeaders

        public String[] getColumnHeaders()

        Gets the headers of the columns.

        The headers match the property id:s given by the set visible column headers. The table must be set in either COLUMN_HEADER_MODE_EXPLICIT or COLUMN_HEADER_MODE_EXPLICIT_DEFAULTS_ID mode to show the headers. In the defaults mode any nulls in the headers array are replaced with id.toString().

        Returns:

        the Array of column headers.

      • setColumnHeaders

        public void setColumnHeaders​(String... columnHeaders)

        Sets the headers of the columns.

        The headers match the property id:s given by the set visible column headers. The table must be set in either COLUMN_HEADER_MODE_EXPLICIT or COLUMN_HEADER_MODE_EXPLICIT_DEFAULTS_ID mode to show the headers. In the defaults mode any nulls in the headers array are replaced with id.toString() outputs when rendering.

        Parameters:

        columnHeaders - the Array of column headers that match the getVisibleColumns() method.

      • setColumnWidth

        public void setColumnWidth​(Object propertyId,
                           int width)

        Sets columns width (in pixels). Theme may not necessarily respect very small or very big values. Setting width to -1 (default) means that theme will make decision of width.

        Column can either have a fixed width or expand ratio. The latter one set is used. See @link setColumnExpandRatio(Object, float).

        Parameters:

        propertyId - columns property id

        width - width to be reserved for columns content

        Since:

        4.0.3

      • setColumnExpandRatio

        public void setColumnExpandRatio​(Object propertyId,
                                 float expandRatio)

        Sets the column expand ratio for given column.

        Expand ratios can be defined to customize the way how excess space is divided among columns. Table can have excess space if it has its width defined and there is horizontally more space than columns consume naturally. Excess space is the space that is not used by columns with explicit width (see setColumnWidth(Object, int)) or with natural width (no width nor expand ratio).

        By default (without expand ratios) the excess space is divided proportionally to columns natural widths.

        Only expand ratios of visible columns are used in final calculations.

        Column can either have a fixed width or expand ratio. The latter one set is used.

        A column with expand ratio is considered to be minimum width by default (if no excess space exists). The minimum width is defined by terminal implementation.

        If terminal implementation supports re-sizable columns the column becomes fixed width column if users resizes the column.

        Parameters:

        propertyId - columns property id

        expandRatio - the expandRatio used to divide excess space for this column

      • getColumnExpandRatio

        public float getColumnExpandRatio​(Object propertyId)

        Gets the column expand ratio for a column. See setColumnExpandRatio(Object, float)

        Parameters:

        propertyId - columns property id

        Returns:

        the expandRatio used to divide excess space for this column

      • getColumnWidth

        public int getColumnWidth​(Object propertyId)

        Gets the pixel width of column

        Parameters:

        propertyId -

        Returns:

        width of column or -1 when value not set

      • getPageLength

        public int getPageLength()

        Gets the page length.

        Setting page length 0 disables paging.

        Returns:

      • setPageLength

        public void setPageLength​(int pageLength)

        Sets the page length.

        Setting page length 0 disables paging. The page length defaults to 15.

        If Table has height set (AbstractComponent.setHeight(float, Unit) ) the client side may update the page length automatically the correct value.

        Parameters:

        pageLength - the length of one page.

      • setCacheRate

        public void setCacheRate​(double cacheRate)

        This method adjusts a possible caching mechanism of table implementation.

        Table component may fetch and render some rows outside visible area. With complex tables (for example containing layouts and components), the client side may become unresponsive. Setting the value lower, UI will become more responsive. With higher values scrolling in client will hit server less frequently.

        The amount of cached rows will be cacheRate multiplied with pageLength ( setPageLength(int) both below and above visible area..

        Parameters:

        cacheRate - a value over 0 (fastest rendering time). Higher value will cache more rows on server (smoother scrolling). Default value is 2.

      • unregisterComponent

        protected void unregisterComponent​(Component component)

        This method cleans up a Component that has been generated when Table is in editable mode. The component needs to be detached from its parent and if it is a field, it needs to be detached from its property data source in order to allow garbage collection to take care of removing the unused component from memory. Override this method and getPropertyValue(Object, Object, Property) with custom logic if you need to deal with buffered fields.

        Adds the new row to table and fill the visible cells (except generated columns) with given values.

        Parameters:

        cells - the Object array that is used for filling the visible cells new row. The types must be settable to visible column property types.

        itemId - the Id the new row. If null, a new id is automatically assigned. If given, the table cannot already have a item with given id.

        Returns:

        Returns item id for the new row. Returns null if operation fails.

        Throws:

        UnsupportedOperationException

      • refreshRowCache

        public void refreshRowCache()

        Discards and recreates the internal row cache. Call this if you make changes that affect the rows but the information about the changes are not automatically propagated to the Table.

        Do not call this e.g. if you have updated the data model through a Property. These types of changes are automatically propagated to the Table.

        A typical case when this is needed is if you update a generator (e.g. CellStyleGenerator) and want to ensure that the rows are redrawn with new styles.

        Note that calling this method is not cheap so avoid calling it unnecessarily.

        Since:

        6.7.2

        Subclass and override this to enable removing of rows, bypassing the normal caching and lazy loading mechanism. This is useful for e.g. TreeTable, when you need to hide certain rows as a node is collapsed. This should return true if the rows pointed to by getFirstAddedItemIndex() and getAddedRowCount() should be hidden instead of added.

        Returns:

        whether the rows to add (see getFirstAddedItemIndex() and getAddedRowCount()) should be added or hidden. For plain Table it is always false.

      • getFirstUpdatedItemIndex

      • addGeneratedColumn

        public void addGeneratedColumn​(Object id,
                               Table.ColumnGenerator generatedColumn)

        Adds a generated column to the Table.

        A generated column is a column that exists only in the Table, not as a property in the underlying Container. It shows up just as a regular column.

        A generated column will override a property with the same id, so that the generated column is shown instead of the column representing the property. Note that getContainerProperty() will still get the real property.

        Table will not listen to value change events from properties overridden by generated columns. If the content of your generated column depends on properties that are not directly visible in the table, attach value change listener to update the content on all depended properties. Otherwise your UI might not get updated as expected.

        Also note that getVisibleColumns() will return the generated columns, while getContainerPropertyIds() will not.

        Parameters:

        id - the id of the column to be added

        generatedColumn - the Table.ColumnGenerator to use for this column

      • removeGeneratedColumn

        public boolean removeGeneratedColumn​(Object columnId)

        Removes a generated column previously added with addGeneratedColumn.

        Parameters:

        columnId - id of the generated column to remove

        Returns:

        true if the column could be removed (existed in the Table)

      • getVisibleItemIds

        public Collection<?> getVisibleItemIds()

        Returns item identifiers of the items which are currently rendered on the client.

        Note, that some due to historical reasons the name of the method is bit misleading. Some items may be partly or totally out of the viewport of the table's scrollable area. Actually detecting rows which can be actually seen by the end user may be problematic due to the client server architecture. Using getCurrentPageFirstItemId() combined with getPageLength() may produce good enough estimates in some situations.

        Description copied from interface: Component

        Sets the visibility of the component.

        Visible components are drawn in the user interface, while invisible ones are not. The effect is not merely a cosmetic CSS change - no information about an invisible component will be sent to the client. The effect is thus the same as removing the component from its parent.

 readonly.setValue("You can't see this!");
 readonly.setVisible(false);
 layout.addComponent(readonly);

        A component is visible only if all of its parents are also visible. If a component is explicitly set to be invisible, changes in the visibility of its parents will not change the visibility of the component.

        Specified by:

        setVisible in interface Component

        Overrides:

        setVisible in class AbstractComponent
