Description

Hey,

until 3.3.5 the "emptyText" of a WInPlaceEdit wasn't rendered in the "lineEdit" widget and now it is (fear enough).

In my use case I use a XHTMLText format for the "textWidget" of the WInPlaceEdit, so that (only) the placeholder text is rendered "Italic":

    edit_ = new Wt::WInPlaceEdit();
    edit_->setButtonsEnabled(false);
    edit_->setPlaceholderText(WString("<i>not avaliable</i>"));
    edit_->textWidget()->setTextFormat(XHTMLText);

How could I ignore/remove the html tags of the "PlaceholderText" if the "lineEdit" is empty.

Regards,

Stoycho

I'm not entirely sure how to resolve this in the library. But can you not work around the issue like below?

edit_ = new Wt::WInPlaceEdit();
edit_->setButtonsEnabled(false);
edit_->setPlaceholderText(WString("<i>not avaliable</i>"));
edit_->linedEdit()->setPlaceholderText(WString::Empty);
edit_->textWidget()->setTextFormat(XHTMLText);

Hey,

In order to make this work around really work, you have to distinguish between the place holder of the WInPlaceEdit's "textWidget" and that of the "lineEdit", because in the current implementation you have a single place holders due to:

const WString& WInPlaceEdit::placeholderText() const
{
  return edit_->placeholderText();
}

The following do the trick:

...
WString textPlaceHolder_;
...
void WInPlaceEdit::setPlaceholderText(const WString& text)
{
  textPlaceHolder_ = text;
  edit_->setPlaceholderText(text);
  if (empty_)
    text_->setText(text);
}

const WString& WInPlaceEdit::placeholderText() const
{
  return textPlaceHolder_;
}

regards,

Stoycho
