Bug ID: 163436
Summary: Impress: deleted text in placeholder textbox fails to
create an undo action
Product: LibreOffice
Version: Inherited From OOo
Hardware: All
OS: All
Status: UNCONFIRMED
Severity: minor
Priority: medium
Component: Impress
Assignee: libreoffice-bugs@lists.freedesktop.org

When deleting placeholder text (for titles or text content for example), there
is no ability to undo the deleted text.
Steps to reproduce:
1.) open attachment 159314 (Paint.odp)
2.) Select all the title text "Header" and delete it. (Note that there is an
textbox-undo entry "Delete")
3.) change focus by clicking on the slide itself above the title box. (Note
that the title box changes to the default placeholder text "Click to add
Title". Note the problem this bug report is complaining about - that there is
no slide-undo entry for the changed textbox content.)
The same thing is true for the text content placeholder.
Already true in OOo 3.3. (There, an undo step is created, but it does
nothing...)
The do-nothing undo entry for the title stopped being created in 7.2 with
commit f582670131dc211e472960ecff1826f7b133b083

Use value comparison here
This was always comparing pointers, ever since commit
cb07ed8c74d71de9ef512c7a3568c7ee85585cef. They could only
happen to be not different if they are both nullptr. But
the uses of the function seem to expect value comparison
(see SdrObjEditView::ImpChainingEventHdl,
SdrObjEditView::SdrEndTextEdit).
Reviewed-on: https://gerrit.libreoffice.org/c/core/+/109284
The do-nothing undo entry for the text content is too indeterminate to
bibisect. Under certain steps (or perhaps timing) I can occasionally get an
undo step being created.
