We are implementing an extension of ez. There we created a second window and show in this window a translation of the text in the first window. Now we want to fetch the mouse click, so that we can scroll in the second window to the correct place. In which class (we think that it should be a ..._Hit method) and method will the cursor be set, when the user clicks on a position in the text. Can you please help us.

I'm not exactly sure what you asking. If you're asking, "Where in the text object does the cursor position get set when a user clicks on some text?", the answer is textv.c:textview__Hit(). There is some code at the top of that method that sets the cursor: if (action == view_LeftDown) { mark_SetPos(self->dot, newLeftPos); mark_SetLength(self->dot, newRightPos - newLeftPos); If you're asking, "After a hit in some text, how can we get the current cursor {location,length}?, the answer is: textview_GetDotPosition(textv); textview_GetDotLength(textv); Gary Keim ATK Group

A possible way to do this is to create a new view subclass that simply puts up a textview to fill its entire area. The new view's Hit method will pass on the mouse click to the subview (textview containing the original text), then find out where the text cursor is in the subview, then signal the other part of the application (which has the translated text). Shame keystrokes don't go through some similar mechanism. Bill
