Basic Event Handling
The code listing below shows how basic events can be handled. When calling the MapForceControl’s open method, or when trying to open a file via the menu or Project tree, the onOpenedOrFocused event is sent to the attached event handler. The basic handling for this event is opening the file by calling the MapForceDocumentControl’s open method.
01 // Open the Marketing file when button is pressed
02 btnMarkExp.addActionListener( new ActionListener() {
03 public void actionPerformed(ActionEvent e) {
04 try {
05 // Instruct the Document control to open the file - avoid calling the open method of MapForceControl (see help)
06 mapForceDocument.open( strExamplesFolder + "MarketingExpenses.mfd" );
07 mapForceDocument.requestFocusInWindow();
08 } catch (AutomationException e1) {
09 e1.printStackTrace();
10 }
11 }
12 } );
13 public void onOpenedOrFocused( String i_strFileName, boolean i_bOpenWithThisControl, boolean i_bFileAlreadyOpened ) throws AutomationException
14 {
15 // Handle the New/Open events coming from the Project tree or from the menus
16 if ( !i_bFileAlreadyOpened )
17 {
18 // This is basically an SDI interface, so open the file in the already existing document control
19 try {
20 MapForceContainer.mapForceDocument.open( i_strFileName );
21 MapForceContainer.mapForceDocument.requestFocusInWindow();
22 } catch (Exception e) {
23 e.printStackTrace();
24 }
25 }
26 }
