Isn't there a way to enable this again?
I'm indeed building an Eclipse plug-in where I added a number of widgets
(StyledText's among other) to my custom editor that is derived from
TextEditor.
Basically, I'm doing this in the createSourceViewer method, where I
create widgets that have the Composite handed to me as the first
parameter of createSourceViewer as parent. One of the things I also do
in createSourceViewer is creating a SourceViewer derived class, which I
ultimately return in this method.
Al the widgets I create show up and behave as expected except that, like
I said, cut, copy, paste don't work.
I now circumvented this problem by overiding doOperation and
canDoOperation, and manually relaying ITextOperationTarget's CUT, COPY
and PASTE commands to my child widgets. This is quite a lot of work,
since especially for the canDoOperation I also need to track whether
each of my widgets has a text selection.
(as a side note: I run into another problem here, and that is that Text
does not seem to fire SelectionListener events when any content is
selected. I'm using a TextCellEditor now, and these DO fire on selection
but it's a different event: PropertyChangedEvent. Is this a bug? I
looked into the source of TextCellEditor and it seems to confirm this.)
The entire aproach seems a bit over the top. Does anyone knows how I can
add widgets to an editor and have cut/copy/paste work automatically?
(i.e. to re-enable it again).
