====== Sample : Zoom to the bounds of an object====== This example documents how you can select a number of objects and then zoom to the extent of the selection. What basically happens is we : * Execute a startup operation (implies we zoom to the focus rectangle after execution) * Execute a number of [[flashmap:ios:operation:index|XML Operations]] inside the startup operation (selecting the objects and returning the right focus to the client). ===== Sample Setup =====

zoomToExtent() - zooms to the maximum allowed extent.
zoomToObjects() - zooms to objects with attribute OIDN set to 5681 or 5690.

You need to upgrade your Flash Player.

===== Overview ===== ==== Zoom To Extent ====


var ofm;

this.zoomToExtent = function()
{
    ofm.zoomToExtent();
}

We execute the zoomToExtent() function. ==== Zoom To Object ==== We use a custom startup operation to make the selection :


var ofm;

this.zoomToObjects = function() {
    var layer = ofm.getSelectionLayer();
    var margin = 10;
    var operation = "\
         \
            \
              FocusSelection\
              "+ layer  +"\
              \
                 1\
                 \
                    Attributes\
                    OIDN\
                    5681,5690\
                    false\
                 \
              \
              ,\
           \
           \
           \
              FocusSelection\
           \
           \
              "+ margin +"\
           \
        ";
    
    ofm.runPlainStartupOperation(operation);
}

=== Overview === We execute the following operations : * SelectObjects : Select the object in a separate selectiongroup named "FocusSelection" * ClearFocus : Clear the existing server-side focus rectangle * AddSelectionToFocus : Add the bounds of the "FocusSelection" selectiongroup to the server-side focus rectangle. * GetFocus : Get the server-side focus rectangle. All these operations are executed as a "startup operation" which implies the following : * A server-side focus rectangle may be returned and will be copied to the client-side focus rectangle. * The client will automatically zoom to the client-side focus rectangle after execution. == Pattern Searches == The attribute value may contain a unix-style wildcard using filename expansion -- also known as "[[http://tldp.org/LDP/abs/html/globbingref.html|globbing]]". By adding the ''false'' tag of the '''' element, you can use wildcards in your attribute values. Example : ''[!-]*'' would match any string not starting with '-'.
