Overview: In Master Slide View, attempting to delete a text box that was not manually added causes a message to be displayed stating that the function cannot be run with the selected objects. Version: libreoffice-impress.x86_64 1:24.8.4.2-2.fc41 Reproducible: Always Steps to Reproduce: 1. Open a new slide presentation in LibreOffice Impress. 2. Go to View > Master Slide. 3. Select any existing text box. 4. Attempt to delete the text box. Actual Results: A message is displayed stating the following: "This function cannot be run with the selected objects." Expected Results: The text box should be deleted.
From upstream: --- The master slide has no "text box" but "Area for Autolayout". The purpose of these is to set the position and size of title object, subtitle object and outline object. And you can style these object there, although the latter is possible and better done in sidebar Styles > Presentation Styles. Whether these objects are shown on a slide is determined by the layout of the individual slide. LibreOffice (and the underlying ODF standard) use a different approach than MS Office (and the underlying OOXML standard). In MS Office the layout is bound to a master slide, but in LibreOffice you can combine any master slide with any layout. So it is not a bug that the "Area for Autolayout" objects cannot be deleted. There exists requests to specify a way to bound a layout to a master slide, see bug 155774 or bug 62332. You might want to add you to CC there. Further related bugs are bug 164877, bug 142512, bug102318 and bug 93087. The objects "Data Area", "Footer Area" and "Slide Number Area" are different. You can delete them or make them invisible in menu Insert > Header and Footer in master view. ---
