This approach worked.  I checked in the cset here http://hg.savannah.gnu.org/hgweb/octave/rev/f9fe8cf64e09.

Closing as fixed.

The icons generally change with the desktop theme which is probably why this wasn't spotted on Linux (which was supplying any missing icons from a deep reserve of icons).  On Windows, I guess , we need to provide all of the icons that we use.

And yes, reflecting the icon was a kluge.  The go-down icon directly from Tango has appropriate attention by a graphics designer.

Looking at the archive, flipping the icon about a horizontal line would have a different lighted portion than the tango version.  Ha, might confuse people's sense of light source.  In linux, the icons are a plain flat shade, but probably can change with the desktop theme.

I'm attaching go-down.png and go-down.svg for your convenience. I downloaded the latest version of the icon theme, verified that the other svg files matched, and used rsvg-convert to create a 128x128 png from go-down.svg.

I agree.  I'll swap in the tango production icon if this approach works.

I think it would be better to get the icon from the original source:


Inside the archive, the original source files pulled into Octave are under tango-icon-theme-0.8.90/scalable/actions.

I've made a go-down icon by reflecting the go-up icon across a vertical line.  I have to go through the full MXE build cycle to check if this works.  Stand by.

The reason must be that there is no icon in Octave's repository for go-down.xyz:

@linux ~/octave/octave/octave $ ls libgui/*/*/*go-*
libgui/src/icons/go-first.png  libgui/src/icons/go-last.svg
libgui/src/icons/go-first.svg  libgui/src/icons/go-up.png
libgui/src/icons/go-last.png   libgui/src/icons/go-up.svg

The "go-down" icon name is in this list of standard names:


I suppose on linux the resource_manager::icon ("go-down") routine finds the icon somewhere else on the system.  On Windows, not.

Confirmed.  Attached is an image showing the blank button on a Windows XP VM.

Showing a help page of the online documentation in the gui documentation pane, press ctrl-F and a input search will display below the help page.

There are tow buttons on the right of the input fields, one for serach forward, other other for search backward.

The search forward button is missing on any text or icon.

In linux it appears ok.
