geotagging.c: view entire track by clicking on list of track segments or use the shortcut

[esq4]

To continue the conversation #17907.
I made three ways:
double-clicking LMB on the list of track segments
clicking LMB on the list header
shortcut option

@esq4 : I rarely use the geotagging support, can you help me test this by providing a step-by-step procedure? TIA.

[esq4]

@TurboGit : In the map view I open the desired gpx file and mark the segments in the list and Darktable shows the whole track in the center of the map. When I select a shot in the filmstrip, it is displayed on the track, and I zoom in on the map to see better where I took it. When I select another shot, it is displayed on the invisible part of the track. And here for a quick view of the whole track (to find this shot) I made three options: double-click LMB on the list of track segments,
LMB click on the list header on the invisible button (overlapping the header except for the checkbox) and the option of a keyboard shortcut that can be assigned to this invisible button. (I use the first two options.)

(I hope that I understood your request correctly.)

Ok, that's probably the missing piece of information. The button is invisible overlay, so:

  GtkWidget *gpx_view_button = dt_action_button_new(self, N_("view entire track"), _refresh_display_all_tracks, self,
                                        _("refresh map to view entire selected track segments"), 0, 0);

The label & tooltip here cannot be displayed on GUI, right?

If that's the case maybe add a comment on the code to ease future maintenance.
