Constructor Detail

DSdbJImage

public DSdbJImage()

Creates a new DSdbImage component.

DSdbJImage

public DSdbJImage(com.klg.jclass.datasource.DataModel dataModel,
                  com.klg.jclass.datasource.MetaDataModel metaDataModel,
                  String columnName)

Creates a new DSdbImage component and binds it to a particular column in a MetaDataModel.

See Also:

NodeProperties.setDataSource(java.lang.Object)

DSdbJImage

public DSdbJImage(com.klg.jclass.datasource.BindingModel binding,
                  String columnName)

Create and binding to a Binding.

Method Detail

setDataBinding

public void setDataBinding(com.klg.jclass.datasource.DataModel dataModel,
                           com.klg.jclass.datasource.MetaDataModel metaDataModel,
                           String columnName)

Sets the parameters for binding the component to a particular column in a MetaDataModel. If the MetaDataModel is the root in the DataModel's MetaDataTree, the DataTableModel is automatically set to the root DataTableModel, otherwise, the DataTableModel is set when an appropriate table becomes available.

setDataBinding

public void setDataBinding(com.klg.jclass.datasource.DataModel dataModel,
                           String metaPath)

Sets the data source to a DataModel and binds the MetaData to the MetaDataModel represented by a "path" of MetaDataModel descriptions separated by '|' (e.g. Orders|Customers).

setDataBinding

public void setDataBinding(String dataBinding)

Sets the data source to the path of DataModel, MetaDataModel descriptions and column name.

setDataBinding

public void setDataBinding(com.klg.jclass.datasource.BindingModel b,
                           String columnName)

Bind to Binding and column.

getDataBinding

public String getDataBinding()

Returns the data binding hierarchy string, starting from a JCTreeData instance name and containing full sequence of MetaDataModel levels starting from the root to the level the table is bound with.

update

public void update(Graphics gc)

Overrides:

update in class JComponent

paint

public void paint(Graphics gc)

Overrides:

paint in class JComponent

setImage

public void setImage(Object item)

Sets the image for the component. If the object is not an image, it is treated as a byte array and converted to an image using JCIconCreator.

getImageDimension

protected Dimension getImageDimension()

Returns the image dimension.

getPreferredSize

public Dimension getPreferredSize()

Returns the preferred size of the component. If no image is set, returns text string dimensions.

Overrides:

getPreferredSize in class JComponent

imageUpdate

public boolean imageUpdate(Image image,
                           int flags,
                           int x,
                           int y,
                           int width,
                           int height)

Returns the minimum size of the component. public Dimension getMinimumSize() { return getPreferredSize(); } /** Returns the minimum size of the component. public Dimension getMaximumSize() { return getPreferredSize(); }

Specified by:

imageUpdate in interface ImageObserver

Overrides:
