[Question] Map panning to left mouse button

[hailstorm75]

I want to allow users to pan within the node editor using the left mouse button.

Similarly to, e.g., Blender's tool selection that modifies what the left mouse button does, I wish to introduce three tools for operating the node editor:

• Select - the default
• Move - left click + drag pans the editor
• Delete - clicking or select+release deletes items

I've found that the EditorGestures class is public; thus, it is possible to modify the default gestures to something custom.

However, I couldn't figure out how to detach the selection from the left click.

I've tried the following:

EditorGestures.Selection.DefaultMouseAction = MouseAction.None;
EditorGestures.Selection.Replace = new MouseGesture(MouseAction.None);
EditorGestures.Selection.Remove = new MouseGesture(MouseAction.None);
EditorGestures.Selection.Append = new MouseGesture(MouseAction.None);
EditorGestures.Selection.Invert = new MouseGesture(MouseAction.None);

EditorGestures.Pan = new MultiGesture(MultiGesture.Match.Any, new MouseGesture(MouseAction.LeftClick), new MouseGesture(MouseAction.MiddleClick));

Could you please point me in the right direction?

Given how these gestures are implemented, I'd assume it should be fine to modify them during the runtime.
Is that correct?

Hi! You should be able to modify the gestures at runtime, however it seems that the select gesture property is missing the setter. I'll create a PR to address that. Do you build from the source code or from the nuget package?

I use the NuGet package

I created the PR and, it looks like not all the gestures were customizable at runtime, especially the ones used for the EditorCommands. Therefore it resulted in more work than expected. Could you please let me know if this suits your needs? I'm open to suggestions and ideas. #104

Based on the description of the PR, this looks perfect. I shall do some testing today and let you know.

I merged the PR and will push a new release to NuGet soon. Please feel free to reopen the issue if needed.
