Layer Control
MapXtreme v7.1 427 Developer Guide
• To rename any item in the layer tree, right-click the item and choose Rename. Alternately, you
can press F2 to rename the selected item. Note that renaming a layer in this manner does not
rename the original table; the rename operation simply changes the text that is displayed in the
layer tree. The information is stored in the workspace file when the workspace is saved.
• To remove a layer in the layer tree, right-click the item and choose Remove. Alternately, you can
press the Del key to delete the layer.
• By default, a layer is selectable when it is added to a map. This is controlled by the Selectable
check box of the Options tab in Layer Control (see
Options ). However, you can designate it as
the only selectable layer, and all other layers will be set to unselectable. This is very convenient if
you have a map with many layers but only want one layer to have selectable features. To specify
only one layer as selectable:
a. Right-click the layer name in the Layer Control or access the context menu.
b. Select Make This the Only Selectable Layer. This single map layer now has selectable
features. That is, you can use any of the selection tools to select objects on the map. All other
map layers will be unselectable.
Layer Control Tabs
The layer control tabs underneath the layer tree provide additional settings and controls that you can
apply to the map as well as to each layer in the map. Different tabs control map and layer settings.
The tabs that appear depend on whether the map or a layer is highlighted in the layer tree, as well
as what kind of layer is highlighted. For example, when you highlight the map in the layer tree, the
map tabs appear; when you highlight a layer, the layer tabs appear. If you highlight a theme, label, or
graticule layer, tabs that are specific to those layers will appear. The next sections explain the
options in each of the tabs.
Map Settings
When you select a map in the layer tree, the following tabs are available: View, Editing, Tools, Style,
Coordinate System, and Extents.
View
The View tab enables you to control the overall appearance of the map. You can set the zoom level,
scale, a center point (in degrees), and a rotation angle. Click the Apply button to apply your settings.
L
For raster reprojection, set the rotation angle in this tab and turn the reprojection on/off from
the Raster Reprojection tab. See
Raster Reprojection .
Editing
The options in the Editing tab enable you to control certain map editing tasks such as the styles used
for drawing objects (if your application uses drawing tools), resizing objects, and moving and
deleting object nodes.
