Real Wait Cursor? [message #98751]

Hello!

By default, RWT will show a wait cursor on long running events which
doesn't avoid mouse clicks (background activity mouse cursor).

Is there a possibility to switch to a real wait cursor, which avoids mouse
clicks and therefore doesn't allow user input until background activity
has ended up?

Or as an alternative: Is there any chance to block user input in general
while event handling is running? (imho W4T had the ability to show a popup
(e.g. a GIF) which blocks any user input)

Regards,
Andre Weber

We don't block user input during requests as this would lead to a
sluggish user experience. There are a lot of cases where the user issues
multiple clicks or key events in a sequence. Examples are keyboard
navigation in a Table, increasing the value of a Spinner or even typing
into a Text with a ModifyListener attached. The user would always have
to wait a little while between sequential actions.

You can open a modal Shell to block user input. The shell can be
invisible by leaving it empty, borderless (SWT.NONE) and transparent
(Shell#setAlpha).

Hope that helps,
Ralf

Thanks for reply!

We will think about the modal dialog solution, although it desires a major
application design intervention.

Hi all!

We have a similar or connected problem.

We have an Eclipse RCP application and in case of server disconnection we would like that the cursor changes to HOURGLASS. It works ok for a normal frame, but if a dialog is active, then in dialog the cursor remains ARROW.

Any idea?
