Configuration changes event ?

[Vince]

Hello,

Is there a configuration changes event emitted ?

My use case is to detect proxy settings changes in order to rebuild plugin http client according to this new settings.

Hi Vincent,
We do not have such callbacks, does the client change the HTTP proxy configuration from inside Oxygen or from the operating system?

Hi Radu,

Our plugin load the HTTP proxy configuration from inside Oxygen.
If the settings are modified from preferences pages, we need to restart oXygen to force rebuild the HTTP client and load the new settings.
If an event or callback was sent, we could intercept it to rebuild the client without restarting oXygen.

Thx

Hi,

Maybe you can try something like:

Code: Select all

        PluginWorkspaceProvider.getPluginWorkspace().addGlobalOptionListener(new OptionListener() {
          @Override
          public void optionValueChanged(OptionChangedEvent event) {
            if(event.getOptionKey() != null && event.getOptionKey().startsWith("http.proxy")) {
              //Proxy setting changed
            }
          }
        });

Hi,

Could you tell me exactly what setting you changed in the Oxygen Preferences->"Network Connection Settings / Proxy" page to see if change events are received in the plugin? I could try to test this on my side.

In proxy settings page, I changed from direct connection to manual proxy configuration.
I set Web proxy http address and port.
Finally, i saved preferences.

Hi Vincent,

I tested on my side and the code should look something like this:

Code: Select all

      String[] proxyKeys = new String[] {
	  "http.proxy.direct",
          "http.proxy.system",
          "http.proxy.set",
          "http.proxy.manual",
          "http.proxy.port",
          "http.proxy.host",
          "http.proxy.user",
          "http.proxy.password",
      };
      for (int i = 0; i < proxyKeys.length; i++) {
        PluginWorkspaceProvider.getPluginWorkspace().addGlobalOptionListener(new OptionListener(proxyKeys[i]) {
          @Override
          public void optionValueChanged(OptionChangedEvent event) {
            System.err.println(event.getOptionKey());
          }
        });
      }

So you need to add a separate option listener for each Oxygen specific option key related to the proxy.
If you change multiple fields in the preferences, you will receive notifications for each of the changed values.
