BUILDING APPLICATIONS WITH VISUAL JAVABEANS
8. Compile and run the application to confirm that the GUI has been laid out as
shown:
A standard Java layout manager (BorderLayout) has been used to position the
components. It manages the layout and sizes of the components for you. You
should be able to resize the window and see that the components get updated
appropriately without requiring any explicit resizing code.
Loading map documents
1. Now that the components have been added, you can load map documents into
the controls. To do this, add the following imports to MapViewerFrame.java:
For cross-platform compatibility, the filenames
and pathnames used to store data must be
lowercased for Solaris and Linux.
import com.esri.arcgis.beans.pagelayout.IPageLayoutControlEventsAdapter;
import
com.esri.arcgis.beans.pagelayout.IPageLayoutControlEventsOnPageLayoutReplacedEvent;
2. Add the following code to the end of the buildAndShow method, just before
the call to this.setVisible.
public void buildAndShow() throws IOException {
. . .
. . .
addEventListeners();

// Load a preauthored map document into the PageLayout bean.
String documentPath = new java.io.File("../../../../../../data/
arcgis_engine_developer_guide/gulf of st. lawrence.mxd").getAbsolutePath();
if (pageLayout.checkMxFile(documentPath))
pageLayout.loadMxFile(documentPath,null);
this.setVisible(true);
2. When the document is loaded into the pageLayout bean, an
onPageLayoutReplaced event is generated. You will add code to load the same
map document in the map component in response to this event. In the
addEventListeners() method, add the event listener to the pageLayout component
for the onPageLayoutReplaced event, as an anonymous inner class, using
IPageLayoutControlEventsAdapter.
