The style boxes enable you to specify the default styles of any drawing tools that your application
uses. Click on a box to open the corresponding style dialog box. The settings you select are saved in
the workspace. When a user opens the workspace in an application that uses drawing tools, the
application uses these style settings when the user draws objects on the map.
You can also specify whether you want to delete or move duplicate nodes. Check the appropriate
checkbox.
You can specify an Edit mode for the map:
• None – No editing can be done on the map.
• Allow moving and resizing – Map objects can be moved and resized.
• Allow node editing – Nodes can be moved or deleted.
• Allow node adding – You can add nodes to objects.
The Edit mode you select applies to all editable layers in the map. You control a layer’s editability by
checking the box Editable on the layer’s Options tab.
When in Edit mode, it is a good idea to turn on the nodes for your map features. Highlight the layer
node (not the map node) and check the box on the Visibility tab.
To control whether labels are editable, check or clear the checkbox Labels are editable.
For an example that utilizes Edit mode, see Editing a FeatureGeometry with the Select Tool .
Tools
The Tools tab enables you to control the display of InfoTips, activate Snap to Nodes and set a snap
tolerance, and activate Dynamic Selection tools.
The Show InfoTips checkbox controls whether information about the feature displays in a pop-up
when you hover over the feature with a select tool. See
Options .
If the Snap To Node check box is selected, map tools such as the Select tool will automatically
search for nodes that are nearby. If a node is nearby, a crosshair will appear to indicate the position
of the nearest node. For example, you might want to select the Snap To Node check box if you are
using the Radius Search tool, and you want to make sure that the search is centered at the exact
location of a point feature on your map. The Snap To Node feature is particularly important in
applications that provide drawing tools, because users often need to draw features at the exact
location of existing features.
