The Calendar, Memos and Tasks views use to do D-Bus calls to the backends on the main (UI) thread, which could result in UI freezes, until the operation was done on the backend (and server) side. This commit fixes that by invoking the operations in a dedicated thread. It has few additional advantages too: - operations can be cancelled - proper error reporting to a user - less code duplication between the views for common operations There had been fixed some performance issues when selecting/unselecting sources in the source selector as well.

|
* automatically for each subclass and shared across

|
|
* for each subclass and shared across all instances
|

|
|
* @get_search_name: Class method to obtain a suitable name for the
|
|
* current search criteria. Subclasses should rarely
|
|
* need to override the default behavior.
|
|
* @toggled: Class method for the #EShellView::toggled signal.
|
|
* Subclasses should rarely need to override the
|
|
* default behavior.
|
|
* @clear_search: Class method for the #EShellView::clear-search
|
|
* signal. The default method sets the
|
|
* #EShellView:search-rule to %NULL and then emits
|
|
* the #EShellView::execute-search signal.
|
|
* @custom_search: Class method for the #EShellView::custom-search
|
|
* signal. This is emitted prior to executing an
|
|
* advanced or saved search. The default method sets

|
* the #EShellView:search-rule property and then emits
|
|
* the #EShellView::execute-search signal.
|
|
* @execute_search: Class method for the #EShellView::execute-search
|
|
* signal. There is no default behavior; subclasses
|
|
* should override this.
