This behavior is expected - unfortunately it is not possible to detect mouse events over Java applets as they are never fired by the browser in the first place. That is why the RadSplitBar never receives the mouseup event and thus you cannot release it over the applet.
The plugin browser architecture works in the following manner:
- A rectangular portion of the page is "given" to the plugin to display a document.
- All events are managed by the plugin and no event communication or propagation occurs from the plugin area to the browser.
The RadSplitter control supports a property LiveResize
, and if you set it to true
and test it, you will see that when moving the mouse slowly, everything seems to work. But a fast move over the applet would cause the events to get 'lost'.
