[digikam] [Bug 326404] New: Unable to select picture in map view

[Nicofo]

https://bugs.kde.org/show_bug.cgi?id=326404

            Bug ID: 326404
           Summary: Unable to select picture in map view
    Classification: Unclassified
           Product: digikam
           Version: 3.5.0
          Platform: Fedora RPMs
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: NOR
         Component: general
          Assignee: [hidden email]
          Reporter: [hidden email]

The "thumbnail", "preview image" and "Table" views function as expected, but it
is not the case of the "Map" view.
The Map view displays my geolocalized pictures on a map, but I am not able to
select them. I don't think it is normal...
I have tried with buttons 'pan mode', 'zoom into a group' and 'select images'.
The latter doesn't work.

Reproducible: Always




Problem with DK3.5 and 3.4 (not tried with older versions)

No, there is no problem anymore in the "Map" view (selected in the top of the
screen, besides the thumbnails/preview image/Table views).

However the problem is still present in the "Map" selected on the left of the
screen (besides the Albums/Tags/Labels/Fuzzy/People/... buttons). On the little
map that appears on the left, it is not possible to select pictures, whatever
the way I try:
- using the 'select images' button
- using the 'filter images' button (don't know how this is supposed to work ??)
- using 'select images by drawing a rectangle' button (no rectangle appears...)

As dysfunction is in map searches view, this is the right component...

Can you reproduce the problem using digiKam Linux AppImage bundle ? The last
bundle is available at this url:

Hi Gilles,
I tried with DK 5.3 and the problem is still there.
I.e. the map from the left view does not work like the map from the top menu.

- The map from the left menu (besides Albums/Tags/Labels/Fuzzy/People/...
buttons): it is not possible to select pictures by clicking on them (which is
the most obvious and convenient way to select pictures I think).
- While it works well in the map on the top menu (besides Thumbnails and
Preview_Image). There just click on a pictures and its easy.

I suppose the map view from the left could also work like that to be able to
select pictures easily ?

I have similar problems in my DK 5.4.0. The "Select images" button works very
strange in the Left Sidebar, if there are already a number of pictures selected
it just toggles the selction of the one I'm clicking on. In general the shape
of the mouse pointer doesn't change when you switch from one function to
another, it remains the panning mode hand once you where in panning mode. One
time I could make it change after going to "Select images by drawing a
rectangle" but only after clicking several times on the map.
In the map that opens with the main toolbar map button there where no pictures
shown at all at first, only when I changed on the Left Sidebar from Albums to
Map and fumbled a while on that little map they also appeared in the big map in
the View Area.
"Select images by drawing a rectangle" works in principle but it took me a
while to find out that cannot just drag a rectangle by pressing and holding the
left mouse button. You have to click where you want the first corner of the
rectangle and then drag teh rectangle open and click a second time where you
want the other corner. I guess this is not what most users expect.

Nicofo,

After working a while now with all the geolocation tools in digiKam (AppImage
5.5.0) in order to write the doc about it I have an idea what your problem
might be.
In the Map View of the Left Sidebar which is the geolocation search tool the
Select Images button works only on those images which are in your current
region selection, indicated by a rectangle on the map. Here it will just toggle
the selection of the pic or group of pics you are clicking on in the Image Area
(central part of the digiKam window). This can be helpful to fine tune your
selection before carrying out operations from the Right Sidebar or the menus.
The button has no effect on pics outside of the rectangle which is intended
behaviour. Wouldn't make sense anyway since they are not displayed in the Image
Area.
The Filter-images button you mention in Comment 2 filters the result of you
region selection which means that only the  one pic or group of pics you are
clicking on is displayed in the Image Area. This is particular useful if the
map is just showing markers or if the thumbnails are too small to clearly
identify images.
I hope this explanation can solve your problem. If you confirm we could close
this bug. The handbook will be updated with the next release. Remains only the
problem with the shape of the mouse pointer wich is subject of
https://bugs.kde.org/show_bug.cgi?id=376072.

Hello Wolfgang,

thanks for investigating this. I agree with your observations.
It is indeed necessary to first select an area (by rectangle for instance) and
only then it is possible to select pictures inside the rectangle selection.

For me, knowing that, the bug could be closed, but I would like to add these
comments:
1) the fact you need first to use a 'search by area' tool is not intuitive. I
think some easy cosmetic adaptations could be made, like:
 - Move the icons "Search by area" above the other icons could already help
because it is the first action to do.
 - add information that "Select images" button cannot be used if no rectangle
selection is made. Example: by modifying the tooltip - OR - disabling that
button if no selection made - OR - adding a message (in the notification
toolbar) - OR - ...
2) the rectangle selection could (should ?) be changed: as you mentioned,
pressing and holding doesn't work: you need to click to initiate the rectangle
and re-click elsewhere to finish the rectangle.
3) (same comments as yours about the mouse pointer)

Gilles,

I know that Nicofo is absolutely right blamimg this tool for not being
intuitive (because it took me quite some time getting into it) and his
suggestions would be a start at least. For sure there would be more
improvements if one would take the time to think about it.

So what are we going to do with this issue? Leaving this bug open and change it
to wishlist or open a new one as wishlist? Or something else?
