Re: [Qgis-user] mdal / mesh simple formats
Thanks Richard, that looks interesting. I can now get regular grid / square mesh to display correctly but I'm working with tri-mesh and anything I try to load using that ends up like this..Just a line of squares. There's something obvious I'm missing in the format here.

Re: [Qgis-user] mdal / mesh simple formats
Hi Matt, I'm not a Mesh expert either, but I use (and create) netcdf using python using the https://github.com/Unidata/netcdf4-python module Netcdf is pretty good supported in QGIS in my experience Our data has also a time dimension so we use the CF convention [0] and fiddling around with the so called UGRID convention [1] But maybe that is both too much for a simple tin... I Googled: https://stackoverflow.com/questions/48864357/convert-hdf5-to-netcdf4-in-bash-r-python-or-ncl as being able to convert hdf5 to netcdf... didn't/couldn't try/test though..

I'm running QGIS 3.26.2-Buenos Aires installed from osgeo. under the xdmf directory there the xmf/hdf files look pretty similar to what I'm using but they won't load. there's a partial duplicate of the data in the hdf file in that directory as a 2dm file which does work. I'm still not sure if I'm supposed to be able to load the xmf/hdf files directly using mdal? I can easily drop out my hdf5 data to the 2dm format is this the proposed way to do it?

Re: [Qgis-user] Problem reading QGIS menus or tool tips in Ubuntu MATE
QGIS, in the end, delegates the creation of Tooltips and Menu's to the Qt-Toolkit. The Qt-Toolkit then has different implementations to actually draw those, depending on your Operating System. I'm not familiar with Ubuntu MATE, but maybe it's not fully supported by Qt? In other Linux distro's there are often different themes/window managers to choose from, would that help? Ubuntu to me is well known as "the company who tries to know better... and give up after some time"... Is there a special reason to NOT use Gnome as desktop? I'm in favour of diversity, but I think as we (as linux users) are already a minority, we should try to focus/support on not too many flavours. ( I'm OK with KDE/Kubuntu too :-) ) Sorry to be not more helpfull, maybe other MATE users have an idea? Regards, Richard Duivenvoorde PS, googling how MATE differs from Gnome I found: https://itsfoss.com/which-ubuntu-install/ It's based on (OLD!!) gnome2... Please give the new Gnome a try, it's my daily driver for years now, and I'm very happy with it On 8/26/22 01:27, Herman Felderhof via Qgis-user wrote: Background: I have recently upgraded from Ubuntu 20.04 LTS (Focal), to Ubuntu 22.04 (Jammy). QGIS was upgraded at the same time to 3.22 LTR Białowieża. I think I may have had 3.16 LTR Hannover before that but I'm not certain. The Problem: I can only read either the drop down menus in QGIS or the tool tips, it doesn't matter if I choose a light to a dark theme in Ubuntu MATE 22.04. When I switch to a dark theme the menus are okay and I can read them, they have light text on a dark background, but when I hover over an icon the tool tips have light text on a light background and are therefore illegible. The opposite problem occurs whenever I switch to a light theme. What I have tried: Opening other applications to see if it's only QGIS, and no other applications seem to have this problem. I have tried changing to several different themes in Ubuntu MATE, opening and closing QGIS after resetting the theme, rebooting, trying in a different computer, looking to see if I can find any settings to fix the problem, upgrading QGIS from 3.22 LTR Białowieża to 3.26 Buenos Aires, searching web forums in case somebody else has the same problem and a solution is already known. My questions: Are there any settings available to users that I can use to fix this problem? Or is this a bug and outside the scope of ordinary users control?I am not afraid of using the command line or editing files if necessary, especially if I have clear instructions.
