How do I disable tooltips in Books Detail pane?

[karlfranz]

I have a macro that grabs the book subtitle via OCR from the image of the book cover in the Book Details pane. However, sometimes the large tooltip window with the message "Double click to open the Book details window" (along with the book's file path and cover size in pixels), gets in the way of the OCR.

Is there a way to disable it?

Note: the option: Preferences|Look & feel|Main interface|Show tooltips in the book list does not control this.

No there is no option to control it, why are you getting the cover from the book details panel anyway? calibr eincludes an extensive suite of command line utilities you can use to extract data including covers in scripts.

To clarify: I'm not trying to get the covers themselves. I am using the cover image to retrieve subtitles that are often not found in the metadata downloaded from sources like Goodreads or Amazon or is not in the format I prefer. I use Apple's OCR technology to grab this data from cover image. It is very good at recognizing text regardless of fonts and layouts (e.g. vertical or diagonal text, text in an arch, etc.).

My macro allows me to draw a quick selection rectangle around the text on the book cover and it automatically creates my book title in the proper format.

You can right click and open the cover in an image editor which is one extra step but not too onerous.

I could...

I just wondered, since there was an option to hide the tooltips in the book list, if there was a similar option for the book details hiding somewhere and just I couldn't see it.

A more hackish approach would be to run Calibre from source using an edited book_details.py (full path is C:\somefolder\calibre-master\src\calibre\gui2\book_details.py)

I was able to reduce the tooltip to an empty rectangle using this:

def update_tooltip(self, current_path):
        try:
            sz = self.pixmap.size()
        except:
            sz = QSize(0, 0)
        self.setToolTip(
            '<p>'+_('') 
        )

    # }}}

instead of:

def update_tooltip(self, current_path):
        try:
            sz = self.pixmap.size()
        except:
            sz = QSize(0, 0)
        self.setToolTip(
            '<p>'+_('Double click to open the Book details window') +
            '<br><br>' + _('Path') + ': ' + current_path +
            '<br><br>' + _('Cover size: %(width)d x %(height)d pixels')%dict(
                width=sz.width(), height=sz.height())
        )

    # }}}

You can open the cover with a custom keystroke, viz:



On Windows, I've used the IrfanView Tesseract plugin to extract titles, straplines, and author names from covers. Should be easy enough to do something similar with MacOS.
