This page covers core functionality of wxGUI vector digitizer, explains its usage for newcomers.
- see also manual page
- see also GRASS Digitizing tool
- see also other vector related pages
- see also Vector library topology management background
- Global mouse buttons functionality
- Left
- Do something related to the selected functionality
- Control-Left
- Cancel operation (depends on selected functionality)
- Middle scrolling
- Zooming
- Middle
- Panning
- Right
- Confirm changes
Adding new features
Point
Mouse buttons functionality:
- Left
- Add new point on given position
Line
Mouse buttons functionality:
- Left
- Add new vertex on given position
- Right
- Write out the new line with given number of vertices
- Control+Left
- Remove last added vertex from the line
Boundary
Mouse buttons functionality:
- Left
- Add new vertex on given position
- Right
- Write out the new boundary with given number of vertices
- Control+Left
- Remove last added vertex from the boundary
Centroid
Mouse buttons functionality:
- Left
- Add new centroid on given position
Area
This functionality combines adding new boundary without category and optionally centroid(s) with category defining new area(s). If the newly added boundary defines an area or two areas on the left and right from the boundary it will also add new centroid(s) which define the newly created area(s).
Mouse buttons functionality:
- Left
- Add new vertex on given position
- Right
- Write out the new boundary with given number of vertices
- Control+Left
- Remove last added vertex from the boundary
Modifying linear features
This functionality covers linear features (lines and boundaries).
Vertex
Add
Add new vertex to the linear feature (line or boundary). This operation won't change the shape of the selected feature.
Mouse buttons functionality:
- Left
- Place new vertex (in given select threshold)
- Right
- Confirm addition
- Control+Left
- Cancel action (do not add new vertex)
Remove
Remove selected vertex from the linear feature (line or boundary). This operation will change the shape of the selected feature.
Mouse buttons functionality:
- Left
- Select vertex to be removed (in given select threshold)
- Right
- Confirm removal
- Control+Left
- Cancel action (do not remove vertex)
Move
Move selected vertex of the linear feature (line or boundary). This operation will change the shape of the selected feature.
Mouse buttons functionality:
- Left
- Select vertex to be moved (in given select threshold)
- Right
- Confirm new position of the vertex
- Control+Left
- Cancel action (do not move vertex)
Split
Split linear feature (line or boundary) on given position. The results are two linear features with the same category(ies) as the original feature.
Mouse buttons functionality:
- Left
- Select position on the linear feature (in given select threshold)
- Right
- Confirm action
- Control+Left
- Cancel action (do not split selected feature)
Edit
Edit linear feature (line or boundary). Only geometry is changed, categories remain untouched.
Mouse buttons functionality:
- Left
- Select vertex where to start editing
- Add new vertex at given position
- Right
- Confirm changes, rewrite feature
- Control+Left
- Undo last added vertex
Moving features
Move selected feature to the new location.
Mouse buttons functionality:
- Left
- Select feature to be moved (in given select threshold)
- Right
- Confirm action (new location of the feature)
- Control+Left
- Cancel action (do not move selected feature)
Deleting features
Delete selected feature.
Mouse buttons functionality:
- Left
- Select feature to be deleted (in given select threshold)
- Right
- Confirm action (delete feature)
- Control+Left
- Cancel action (do not delete selected feature, unselect feature)
Category/Attributes management
Note: for the modification of attributes in the connected table, use the WxGUI Attribute Table Manager.
Display categories
Dialog 'Update categories' allows adding new layer/category, modifying and deleting existing layer/categories records. Modify mode is enable after clicking on the item which user wants to be modify. For deleting record(s) right click on selected item and choose from contextual menu 'Delete selected/all'.
Mouse buttons functionality:
- Left
- Select feature and show it's categories
Copy categories
@TODO
Duplicate categories
@TODO
Display attributes

Mouse buttons functionality:
- Left
- Select features to be merge (in given select threshold)
- Right
- Confirm action (merge features)
- Control+Left
- Cancel action (do not merge selected features, unselect features)
Break
Break selected linear features on each intersection.
Mouse buttons functionality:
- Left
- Select features to be broken (in given select threshold)
- Right
