Object editing

Select

Single selection

The single-selected Action "SELECT" selects geometric objects by clicking on the object with a single finger. The single-select operation requires the operation layer to be an optional layer.

layer.setSelectable(true);

Step 2: Set the selection status

//Set object operation type as a single option 
mapControl.setAction(Action.SELECT);

Multiple selection

Multi-selected Action "MULTI_SELECT" is multi-selected by clicking each geometric object with one finger. The multi-select operation requires the operation layer to be an optional layer.

Topological editing

iMobile provides a variety of topology editing and capture to facilitate accurate editing of graphic objects.

To implement topological editing, the required class libraries include com.supermap.data.jar, com.supermap.mapping.jar, com.supermap.analyst.jar, so libraries include libimb2d.so, libgnustl_shared.so, libQt5Core.so, libQt5Gui.so, libQt5Svg.so, libQt5Widgets.so.

The key categories and methods are as follows:

Combination surface

Action "COMPE_REGION" of the composite surface function is to combine the selected surface objects in the current layer into a composite object.

Figure: Combination surface

Description:

• Combine two or more surface objects to generate a new composite object, which supports the combination of surface objects in the opposite layer and CAD composite layer.
• The property information of the newly generated composite object is obtained through the callback function.
• When the number of overlapping surfaces of objects is even, the area is displayed as white after combination, which is part of the result data.

Implementation steps:

Step 1: Operate the layer settings

// Set the layer to display, true, means that the layer can be displayed, false, means that the layer is not displayed. 
Layer. setVisible (true); 
// Set the operation layer to be editable, true, which means that the vector layer can be edited, and false, it means that the vector layer cannot be edited. 
layer.setEditable(true); 
// The setting operation layer is optional, true, which means that the vector layer is optional, false, which means that the vector layer is not selectable. 
layer.setSelectable(true);

Step 2: Set the object operation type to the combination surface

//Set the object operation type to the combination surface

Step 4: Submit operation

mapControl.submit();

Notes:

• When there is an inclusion relationship between the combined face objects, it is treated as the hole polygon, and the result is also consistent with the hole polygon result.
• After the combination operation in the surface layer, the two superimposed parts of the surface object are white, which is part of the result and is not missing.

Consolidated surface

Action "UNION_REGION" of the merge surface supports the merger of face objects in the opposite layer and the CAD composite layer.

Figure: Consolidated surface

Description:

• If the surfaces involved in the operation intersect with points, these surface objects are merged into a complex surface object (as shown below, a complex surface object with two sub-objects is generated).

Figure: Point intersection and merge

• If the faces involved in the object operation intersect with the line, the adjacent edges between these face objects will disappear and be merged into a simple surface object.

Figure: Lines intersect and merge

• If the surface of the participating object operation intersects, it will be merged into a simple surface object.

Figure: Face-to-face merge

• If the faces involved in the object operation do not intersect and are not adjacent to each other, a complex surface object will be generated after the merger (the figure below shows the generation of a complex surface object with three child objects).
