background color of RecentFileListBox

I think you ask about white background of ListBox. I have seen this and it is very annoying on Dark themes. Unfortunately I can't find reason. This even not always can be reproduced but often. I will add this to our tasks/bugs database.

I found a bit more information:

the first time you select an office theme that is a different version of office from the current theme, the BackstageListBox theme is wrong (e.g. change from one of the office 2010 themes to one of the office 2013 themes). But then if you select another variant from the same office version (e.g. after selecting office 2013 white, select office 2013 grey), then the BackstageListBox does adopt the correct theme.

Please teach me how to change the background color of CXTPRecentFileListBox.

I want to change the color from white to theme color.

Hi,

I tried how to edit ini(Office2016PowerPointColorful.ini).

[CommandBars.Gallery]

Back = 255 0 0

But the color did'nt change.

Hello hiro-ta,

Maybe your RecentFileList is transparent ?
see implementation of CXTPControlGalleryOffice2013Theme::FillControl()

[CommandBars.Gallery] "Back" is CXTPControlGalleryOffice2013Theme::m_clrBack

Hello hiro-ta,

You need to set breakpoint in method CXTPControlGalleryOffice2013Theme::FillControl() and see what conditions work and what color is used there.

you need to call SetTransparent(FALSE) for gallery control.
If you use CXTPRibbonBackstagePageRecent then see implementation of CXTPRibbonBackstagePageRecent::SetTheme(). It calls

m_wndList.GetGallery()->SetTransparent(FALSE);
before change theme.

By default this option is false, see constructor CXTPControlGallery::CXTPControlGallery().

Set breakpoint in CXTPControlGallery::SetTransparent() or data breakpoint for CXTPControlGallery::m_bTransparent to see where it is changed.

you can change CXTPControlGalleryOffice2013Theme::m_clrBack right after changing theme or hardcode desired color in INI file like described above.

You need to edit and rebuild Office2016.dll (Source\Styles\Office2016\)

Edit desired INI files in section [CommandBars.Gallery] change property "Back"

You did this before but your Recent File List was transparent.

You can change our library, add public setter/getter for that property and rebuild lib.
