If a node is being hovered when the user performs the paste, an
offset is added to the mouse's position, both in the horizontal and
vertical directions. This aims at avoiding a complete overlap with
the nodes on top of which the clipboard content is pasted.
If several nodes are described in the clipboard and are supposed to
be connected with each other, reconnect them together, but do not
attempt to reconnect them to the graph they were copied from, even if
it is the current graph.
When creating a node with a "paste" operation, place the node
on the mouse's position in the graph instead of default position (0,0).
If the mouse is placed on an existing node, the pasted node will be
placed on the mouse's position plus an offset so that the pasted node
does not directly overlap with the existing node.
Attempt to paste the clipboard's content in the graph when Ctrl+V is
pressed. If the clipboard contains a valid node description, add the
corresponding node to the graph.
Otherwise, do nothing.
## Description
Fix various typos in the source code. This includes user facing code, documentation, and source comments. This PR has not been tested.
Closes#1605
Add possibilty to, while computing nodes:
add more nodes to the task manager,
edit, duplicate and remove nodes without breaking the tasks that are submitted
* use it in MetadataListView and GraphEditor 'add Node' menu
* GraphEditor: forward MenuItem key events to searchBar to be able to continue editing the filter even if it lost active focus
* allow to solo a 3D media from the GraphEditor by double clicking on a node or an attribute with the Control modifier pressed
* consistent with Viewer3D.MediaLibrary behavior (solo on Ctrl+Click on visibility button)
* handle supported file extensions in Viewer3DSettings
* add a ToolButton for duplicating/removing following nodes in corresponding entries instead of having a separate item
* change text when those button are hovered to reflect the change of action
* wording: rename "Delete Node" to "Remove Node"
* ease the deletion of a branch from a given starting point
* accessible with alt+del on a node
* re-order menu to put the most destructive operation (Clear Data) at the very end
* keep track of currently hovered node in UIGraph on Python side
* Node: show border on hover + make MouseArea contain everything else to always get hover events, even when cursor is over children attribute pins
