Description
Link the TBX initialization to the SWT ProgressDialog at start up.
At this moment, the progression bar of the dialog "Loading corpora" does not reflect the real tasks executed by the TBX (potentially problematic when having a lot of corpus and partitions).
A temporary workaround would be to switch ProgressDialog to "indeterminate" mode to show to the user that TXM is not hanging up.
A better solution would be to implement Observer pattern with a thread cyclically checking the TBX activity, e.g. numbers of corpus loaded, number of partitions created, and updating the progress bar every x ms or x seconds.
Solution 1¶
- add an initialization level variable in org.txm.toolbox/src/java/org/txm/Toolbox.java
- increment this level according to the steps of initialization, e.g.: 1 = loading properties, 2 = starting corpus engine, 2 = starting statistic engine, etc.
- use this TBX level variable to update the IProgressMonitor state in org.txm.rcpapplication.ApplicationWorkbenchAdvisor.initializeUI(JobHandler)

Some prototype working code dedicated to org.txm.rcpapplication.ApplicationWorkbenchAdvisor.initializeUI(JobHandler) inspired from the solution 1:
Display.getDefault().syncExec(new Runnable() {
@Override
public void run() {
try {
IProgressService service = PlatformUI.getWorkbench().getProgressService();
service.runInUI(service, new IRunnableWithProgress() {
@Override
public void run(final IProgressMonitor monitor) throws InvocationTargetException, InterruptedException {
monitor.beginTask("Initializing TXM Tool box", 200);
if (!Toolbox.isInitialized()) {
try {
new Thread(new Runnable() {
@Override
public void run() {
try {
System.err.println("**************************************ApplicationWorkbenchAdvisor.initializeUI(...).new Runnable() {...}.run().new IRunnableWithProgress() {...}.run(...).new Runnable() {...}.run()");
// for(int i = 0; i < 999999999; i++) {
//
// }
Toolbox.initialize(getProperties());
}
catch(Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
// Initializes the charts SWT component provider
Log.info(Messages.ApplicationWorkbenchAdvisor_87);
Application.swtComponentProvider = SWTChartsComponentProvider.createChartsSWTComponentProvider(Toolbox.getChartsEngine());
}
}).start();
int stepsLevel = 0;
monitor.subTask("Loading properties");
while(!Toolbox.isInitialized()) {
//System.err.println("ApplicationWorkbenchAdvisor.initializeUI(...).new Runnable() {...}.run().new IRunnableWithProgress() {...}.run(...).new Runnable() {...}.run()");
monitor.worked(1);
// Properties loading terminated
if(!Toolbox.getProperties().isEmpty() && stepsLevel < 1) {
stepsLevel++;
monitor.subTask("Starting Corpus Engine");
}
else if(Toolbox.isSearchEngineInitialized() && stepsLevel < 2) {
stepsLevel++;
monitor.subTask("Starting Statistic Engine");
}
else if(Toolbox.isStatEngineInitialized() && stepsLevel < 3) {
stepsLevel++;
monitor.subTask("Loading corpora");
}
else if(stepsLevel == 3) {
monitor.subTask("Loading corpora: " + CorpusManager.getCorpusManager().getCorpora().get(0).getName());
}
//Display.getDefault().readAndDispatch();
// Display.getDefault().getActiveShell().redraw();
try {
Thread.sleep(100);
}
catch(InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
monitor.done();
}
}, ResourcesPlugin.getWorkspace().getRoot());
}
catch(InvocationTargetException e) {
// TODO Auto-generated catch block
e.printStackTrace();

catch(InterruptedException e) {
