Hi,
i would like to use multi-workspace by user for save preferences, e.g.:
my_application/workspace/user1/.metadata
my_application/workspace/user2/.metadata
etc.
I have followed guide http://hexapixel.com/2009/01/12/rcp-workspaces
It is:
1. turn off default workspace
-data @noDefault
2. create custom workspace in the Aplication.java
// create dirs
File workspace = new File("workspace/" + username);
if (!workspace.exists()) workspace.mkdirs();
// create URL and set Location
URL url = new URL("file", null, workspace.getAbsolutePath());
if (url != null) {
Location instanceLoc = Platform.getInstanceLocation();
instanceLoc.set(url, false);
}
That's OK. After user login will be workspace created.
My problem:
In my application I use save preferences (e.g. show chart) in method
saveState(memento) of View this way:
Activator.getDefault().getPreferenceStore().setValue(Prefere nceConstants.SHOW_CHART,
m_chartVisible);
Before I have loaded this preferences as per description mention above,
this way has been followed:
Platform.getPreferencesService().getBoolean(Activator.PLUGIN _ID,
PreferenceConstants.SHOW_CHART, true, null);
But I started to use custome workspace the loading preferences doesn't
work anymore. When I close View these preferences are saved with any
problem into file 'xx.prefs', but after open View
preferences are not loading.
I understood the problem is because of not turn on default workspace
(@noDefault). Do I have to these preferences again somehow loaded? Am I
using for the loading correct getPreferencesService() ?
I have tried after View open loaded preferences again by:
private IPreferenceStore m_preferences =
Activator.getDefault().getPreferenceStore();
try {
m_preferences = new PreferenceStore("xx.prefs");
((PreferenceStore) m_preferences).load();
} catch (IOException e) {
e.printStackTrace();
}
m_preferences.getBoolean(PreferenceConstants.UPDATE_VAR);
It gets better but doesn't work for default values.
How to use loading preferences into workspace? What am I doing wrong?
Thanks!
Martin
