Are there are any build prerequisites for the xdg-desktop-portal-tde
package other than tdelibs|tdebase?
Are any run-time environment variables needed?
Thanks.

I realize the package is still in development, but my understanding of

Hi Darrell,
You need to change some settings in Firefox, it is mentioned in the readme file of
xdg-desktop-portal-tde.
You also need to run xdg-desktop-portal.
I remember there were some instructions on TGW about how to test this (from blu.256) but I
can't seem to find out where
it is now :-(

I think Firefox is configured correctly because with KDE I see the KDE
file picker dialog. In TDE Firefox seems to be configured correctly
because I see the default Qt5 file picker rather than the GTK file picker.
The problem seems to be that Firefox is not finding the TDE portal or
does and is not interpreting properly.
I think the portal package built correctly because I see files being
installed in /usr as well as /opt/trinity.

Hello,
It looks like your Firefox is configured for portals and xdg-desktop-portal-tde probably
installed correctly.
I assume you are running a full TDE session, since the TDE portal will only automatically
start within it.
Getting xdg-desktop-portal to work can be a little tricky and there is always a
probability of a bug, so if you're OK with a little bit of debugging, you can run the
xdg-desktop-portal in verbose mode and mail me the log, or even better post it as an issue
in TGW mentioning the distribution.
How to do it:
```
$ killall xdg-desktop-portal
$ /path/to/xdg-desktop-portal -v
```

I think Michele refers to the 4th comment in this thread:
https://mirror.git.trinitydesktop.org/gitea/TDE/tde/issues/160
You can find a more detailed debugging/testing instruction there.

We should ensure we both agree what a full session entails. I presume I
am, but perhaps I need to know what all is required to be sure.
Getting xdg-desktop-portal to work can be a little
tricky...
I'm still looking at the thread and trying not to get glassy-eyed. In
the mean time, I notice when I launch Firefox that xdg-desktop-portal is
in the process list but so is xdg-desktop-portal-kde. I am going to
offer a wild guess that is why xdg-desktop-portal-tde is not running.
Kind of like the kde version responds first or xdg-desktop-portal is
calling xdg-desktop-portal-kde rather than xdg-desktop-portal-tde.
I manually killed the xdg-desktop-portal-kde process and manually
launched /opt/trinity/lib64/trinity/libexec/xdg-desktop-portal-tde. I
selected File->Open in Firefox and once again the Qt file picker appeared.
When I looked at the process list, xdg-desktop-portal-tde was still
running but so was xdg-desktop-portal-kde.
At this point I suspect xdg-desktop-portal does not know about
xdg-desktop-portal-tde or does not know how/where to call the TDE portal.
So either a bug or I do not know how to compile xdg-desktop-portal-tde
correctly. Could be a bug, perhaps xdg-desktop-portal-tde hasn't been
tested in Slackware. I know there a some Slackware users out there and
perhaps they can pitch in and help.
I would not be surprised I am not compiling correctly and despite no
build failures, perhaps files are not being installed in the places
where xdg-desktop-portal looks to launch the appropriate DE file picker.

I make same observation with xdg-desktop-portal-gtk

xdg-desktop-portal-tde or does not know how/where to call the TDE portal.
I tried disabling (chmod -x) xdg-desktop-portal-gtk, started chrome and it
blocks, because it wants to spawn the user service via dbus.
Firefox seems to be using it's own file chooser.

I am on debian. I see xdg-desktop-portal-tde registering on dbus, but it
seems it is not providing the interfaces for further consumption.
Will play with it during weekend more.

I don't know the root cause yet, but I have more information to share.
With some reflection, I realized Firefox is launching the KDE file
picker portal and not the generic Qt. I was fooled by this because the
dialog was opening with all of the generic flat icons and did not look
like the normal KDE file picker I had configured in my KDE environment.
The xdg-desktop-portal-tde.desktop is installed in
/opt/trinity/share/applications rather than
/opt/trinity/share/applications/tde like all other TDE desktop files.
The org.freedesktop.impl.portal.desktop.tde.service file is installed in
/usr/share/dbus-1/services, the same place as
org.freedesktop.impl.portal.desktop.kde.service.
The tde.portal file is installed in
/usr/share/xdg-desktop-portal/portals, the same as the kde.portal file.
The tde.portal file has UseIn=Trinity where the kde.portal has UseIn=KDE.
I do not think 'Trinity' is a valid XDG reference and the key should be
UseIn=TDE. The sources show UseIn=Trinity and should be patched to
UseIn=TDE. Refer to
https://specifications.freedesktop.org/menu-spec/latest/onlyshowin-registry….
I changed UseIn=Trinity to UseIn=TDE. Initially that did not seem to do
anything because when I launched Firefox the KDE portal launched. More
on that change later.
Next I moved xdg-desktop-portal-tde.desktop to
/opt/trinity/share/applications/tde/. Moving the file made no difference.
I terminated Firefox and killed all portal processes each time.
Next I killed the portal processes while leaving Firefox running. I
launched /usr/libexec/xdg-desktop-portal --verbose. The output spew
showed that xdg-desktop-portal had selected the TDE portal for the file
picker ("Using tde.portal for org.freedesktop.impl.portal.FileChooser in
TDE"). The process list showed both the KDE and TDE portals. I tried to
use Firefox File-->Open and the TDE file picker dialog opened.
I closed Firefox and killed the portal processes. I launched Firefox and
again killed the portal processes. I manually launched
/usr/libexec/xdg-desktop-portal but not verbose. I launched Firefox and
again the TDE file picker opened.
I closed Firefox and killed the portal processes. I manually launched
/usr/libexec/xdg-desktop-portal without verbose and as a background
process. The process list showed both the KDE and TDE portals. I
launched Firefox and the TDE file picker dialog was used.
I created a $TDEHOME/Autostart desktop file to force launch
/usr/libexec/xdg-desktop-portal. After starting my TDE session, the
process list showed the TDE portal. Again Firefox used the TDE file picker.
Seems when xdg-desktop-portal is manually launched before launching
Firefox then everything behaves as expected. Having Firefox launch
xdg-desktop-portal fails to call the TDE portal.
I removed the temporary autostart file. Although Firefox had
widget.use-xdg-desktop-portal.file-picker=1, just to be sure, I toggled
all other widget.use-xdg-desktop-portal.* options to 1. I then renamed
kde.portal to kde.portal.bak. I logged out and restarted TDE. I verified
no portal processes. I launched Firefox and saw that there was no kde
portal process and the tde portal process was running. Firefox then used
the TDE file picker.
Some more trial-and-error testing indicates UseIn=TDE does need to
change in the sources.
Although the TDE portal will launch manually and everything behaves,
seems KDE is receiving priority over TDE when both portals are
available. I don't know where the mixup might be. Could be me. Could be
Slackware. Could be TDE. Could be something else. I think the TDE portal
package is fine. One way or another something is awry.
I hope the information helps. Any feedback is welcomed. :)

Probably does not cause harm to set all of the Firefox "widget*portal"
options to '1', but my understanding is should not be necessary.
My understanding is the Firefox "widget*portal" options were needed in
the early days of supporting portal tools, but no longer should make a
difference. A setting of '2' should mean Firefox lets the underlying
operating system determine which portal tools to use.
My understanding is everything nowadays should be automatic. Firefox is
supposed to call xdg-desktop-portal and then based on environment
variables, xdg-desktop-portal selects an appropriate desktop environment
(DE) portal. The primary environment variable is $XDG_CURRENT_DESKTOP,
which for TDE should be set to XDG_CURRENT_DESKTOP=TDE. There are more
steps to determine the correct portal if that env. variable is undefined.
On my part that is why I am confused. Everything in my environment seems
to be in order yet xdg-desktop-portal is not selecting TDE unless I
intervene manually. Somehow KDE is selected rather than TDE.

that first one registered is portal-tde.
Although another issue is that portal-tde supports less features.

Is xdg-desktop-portal-tde something that was added since R14.1.3 went GA?

org.freedesktop.impl.portal.desktop.kde.service.
The tde.portal file is installed in
/usr/share/xdg-desktop-portal/portals, the same as the kde.portal file.
The tde.portal file has UseIn=Trinity where the kde.portal has UseIn=KDE.
I do not think 'Trinity' is a valid XDG reference and the key should be
UseIn=TDE. The sources show UseIn=Trinity and should be patched to
UseIn=TDE. Refer to
https://specifications.freedesktop.org/menu-spec/latest/onlyshowin-regist
ry .html.
I changed UseIn=Trinity to UseIn=TDE. Initially that did not seem to do
anything because when I launched Firefox the KDE portal launched. More
on that change later.
Next I moved xdg-desktop-portal-tde.desktop to
/opt/trinity/share/applications/tde/. Moving the file made no
difference.
I terminated Firefox and killed all portal processes each time.
Next I killed the portal processes while leaving Firefox running. I
launched /usr/libexec/xdg-desktop-portal --verbose. The output spew
showed that xdg-desktop-portal had selected the TDE portal for the file
picker ("Using tde.portal for org.freedesktop.impl.portal.FileChooser in
TDE"). The process list showed both the KDE and TDE portals. I tried to
use Firefox File-->Open and the TDE file picker dialog opened.
I closed Firefox and killed the portal processes. I launched Firefox and
again killed the portal processes. I manually launched
/usr/libexec/xdg-desktop-portal but not verbose. I launched Firefox and
again the TDE file picker opened.
I closed Firefox and killed the portal processes. I manually launched
/usr/libexec/xdg-desktop-portal without verbose and as a background
process. The process list showed both the KDE and TDE portals. I
launched Firefox and the TDE file picker dialog was used.
I created a $TDEHOME/Autostart desktop file to force launch
/usr/libexec/xdg-desktop-portal. After starting my TDE session, the
process list showed the TDE portal. Again Firefox used the TDE file
picker.
Seems when xdg-desktop-portal is manually launched before launching
Firefox then everything behaves as expected. Having Firefox launch
xdg-desktop-portal fails to call the TDE portal.
I removed the temporary autostart file. Although Firefox had
widget.use-xdg-desktop-portal.file-picker=1, just to be sure, I toggled
all other widget.use-xdg-desktop-portal.* options to 1. I then renamed
kde.portal to kde.portal.bak. I logged out and restarted TDE. I verified
no portal processes. I launched Firefox and saw that there was no kde
portal process and the tde portal process was running. Firefox then used
the TDE file picker.
Some more trial-and-error testing indicates UseIn=TDE does need to
change in the sources.
Although the TDE portal will launch manually and everything behaves,
seems KDE is receiving priority over TDE when both portals are
available. I don't know where the mixup might be. Could be me. Could be
Slackware. Could be TDE. Could be something else. I think the TDE portal
package is fine. One way or another something is awry.
I hope the information helps. Any feedback is welcomed. :)

Well, I disabled xdg-desktop-portal-gtk and restarted
my machine, then
discovered that there is no xdg-desktop-portal-* in /opt/trinity/lib64 (or in
the openSUSE repository), so firefox hangs when I try to download a file. I
put the gtk part back and restarted my machine and now it works again with
the native firefox file picker.
Is xdg-desktop-portal-tde something that was added since R14.1.3 went GA?
Yes, new to 14.1.3, which is why I am testing. I presume for Debian
folks this package is readily available to download/install.
