That is not supported by default (at least not on Win). Since you switch to another window/process usually this should not be intercepted/prevented by an application. But it is doable using a hook: http://stackoverflow.com/questions/1161053/capturing-keystrokes-without-focu... http://stackoverflow.com/questions/1346689/how-do-i-trap-windows-key-alttab-... Bye T.

I wasn’t able to find something like that.

There is MorphLostFocus, bit is not triggered by World. And not triggered when Pharo loose focus.

Did World trigger a keyboard focus lost announcement?

Hi guys,

I am trying to detect when a user switches her focus from Pharo to another app.

In short I’d like to know when the user switches (i.e., atl+tab) from the Pharo application to another application, losing focus from the development.

I looked into Morphic and I was able to tell when the mouse goes outside the Pharo window. Unfortunately this technique does not work when the user uses alt+tab to switch to another app, since the last mouse event is not outside the Pharo window.

Any suggestion where to look?

Thanks in advance, R

Thanks Igor, Could u please ping me when you manage to have this doable from the image? Thanks in advance! Cheers, R On Jan 13, 2014, at 7:40 PM, Igor Stasenko <siguctua@gmail.com> wrote:

FYI: Right now we're working with Ronie to replace that in VM, so you can handle this kind of events from image.

Thanks in advance, R
