Update the names of the commands that remove images in the "File"
menu to match with those in the Image Gallery menu.
"Clear Images" becomes "Remove All Images" and "Clear All Images" becomes
"Remove Images From All CameraInit Nodes".
Prior to this commit, the `StructureFromMotion` and `SfMTransform` nodes'
were directly set without using the dedicated command. This meant that
the actions to set those attributes through the Image Gallery menu were
not added to the stack of commands, and could not be undone.
In addition to the existing "Remove" menu action in the Image Gallery that
deletes the currently selected image, add a "Remove All Images" menu
action that performs the same action as "Clear Images" from the "File"
menu.
The "Del" key was used as a shortcut to remove the currently selected
image when the Image Gallery has the focus, "Shift+Del" can now also be
used to remove all the images at once.
When all the images in the gallery are cleared using the "Clear Images" or
"Clear All Images" menu action while the "Visualize HDR images" option is
turned on, the gallery is correctly emptied and the viewer correctly reset
but the button remains turned on even though there is nothing left to show.
As it is turned on (although with a "0" count), the gallery remains in
read-only mode and no more image can be dropped until the button is
manually clicked to be turned off. Even after that, it remains clickable
instead of being disabled.
This commit ensures that the button gets disabled if the number of
viewpoints is 0 (meaning the gallery is empty). That way, the button
correctly reflects the current situation, and the gallery is ready to have
images dropped.
...for node attributes and 3D inspector
- add search bar for node attributes
- add search bar for 3D inspector
- improve attributes filtering by adding more flexibility
and fixing some issues
If an attribute's `validValue` is false, and it has a non-empty
`errorMessage`, the following will happen:
- An icon indicating an error will be added next to the attribute's name;
- The color of the label's background will change to red to clearly
indicate that something is wrong with the current value;
- The error message that has been set for this attribute will be displayed
in its tooltip, before its regular description.
When dragging the border between 3D Viewer and 2D Viewer:
- previous behaviour: the Image Gallery is resized instead of
the 2D Viewer
- new behaviour: the 2D Viewer is resized
Also extend the width of the "Node" column to ensure that all nodes,
even those with a long name, can be displayed correctly without overlapping
on the "Issue" column.
If a node has a user-set label (defined through the internal attributes
of the node), its default name (the one that is displayed if no label
has been set) will be displayed next to it.
This allows to find quickly the correspondence between the node's label
and its type / how it is referred to in the current graph's file.
