<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">I dislike the part that exposes the "currentTextLayout()", since it exposes more API (but ok, maybe we must), and it is not flexible. For instance, ktexteditor.git has a multicursor branch, and just getting the "current" text layout is not enough. Could you change it to textLayout(int line), along with a comment that the returned pointer is possibly a nullptr?</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">PS: KateViewInternal.cpp also has a KateWrappingCursor. A proper solution would be to expose this class so that proper text navigation is available everywhere (e.g. KTextEditor::ViewCursor, just like KTextEditor::DocumentCursor).</p></pre>

Any idea how to solve that?</p></pre>

<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;"><div class="codehilite" style="background: #f8f8f8"><pre style="line-height: 125%"><span style="color: #008000; font-weight: bold">KTextEditor</span><span style="color: #666666">:</span><span style="color: #AA22FF">:KateViewCursor</span><span style="color: #666666">(</span><span style="color: #008000; font-weight: bold">KTextEditor</span><span style="color: #666666">:</span><span style="color: #AA22FF">:View</span> <span style="color: #666666">*</span> <span style="color: #008000; font-weight: bold">view</span><span style="color: #666666">);</span>
</pre></div>
</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">Then, can't we qobject_cast this view to KTextEditor::ViewPrivate ? Then we have access to our internal KateView and KateViewInternal.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">We'd need a pimpl-class, i.e. a d-pointer to store the qobject_cast<KTextEditor::ViewPrivate *>(view) as a member variable.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">In addition to this constructor, most of the API from KTextEditor::DocumentCursor [1] and what the Wrapping cursor etc can do right now.</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">Does that make sense / is that feasible?</p>

KateViewInternal is stored there as a private property, the only way would be to expose it instead of currentTextLayout().</p></pre>

I exposed KateViewInternal as I could't find another way to access it from KTE::ViewPrivate, then I had to move KateViewInternal::cache() to public functions to make it accessible in KTE::ViewCursor and now when trying to use WrappingCursor in KTE::DocumentPrivate::del() it crashes in KTE::ViewCursor::makeValid() due to calling KTE::ViewCursor::doc(). Not sure I'm willing to give this more time to implement it the way you want as I already spent a day with it. I'll back to it once I have some free time. Thanks for your help.</p></pre>

Pressing "delete" or "backspace" should remove the entire composed character and not only one base character. You can see how it should behave when using another text editor (e.g. libreoffice)</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">Can be tested with these words: ?????????? or ??????????? or ????????</p>
<p style="padding: 0;text-rendering: inherit;margin: 0;line-height: inherit;white-space: inherit;">Technical details:
I'm not really sure whether exporting current text layout is the right way to do this, I found that this is used when calling moveChar() which moves the cursor exactly by one composed character so I was trying to find a way to do it similarly.</p></pre>
