Hi Isaac,

 

To add the capability to pan northeast/northwest etc. you need to edit
either your application.php & application_contents.php files (where
"application is the name of your application") or to make this a permanent
addition edit ./htdocs/gmapfactory/templates/app_php_file.php and
./htdocs/gmapfactory/build_phtml.php files and make changes similar to the
following:

 

1)       Edit the interface to include controls for the new directions.
This will be added to either the build_phtml.php file around line 574 or to
the application_contents.php file.

2)       Edit the processing files to handle the pan.  This will be done in
two steps:

i)                     Edit the app_php_file.php file around line 101 to
check the url for the new pan commands.  

 

i.e. 

if ( strlen( trim( $http_form_vars["Pan_NorthEast_x"] ) ) > 0 )

{

                  // check mode and set appropriate vars

                  if ( $http_form_vars['RosaMode'] == 1 )

                              $http_form_vars["INPUT_COORD"] = "0,0";

                  else

                              $http_form_vars[ "mainmap_x" ] = "0";

 

                  // set the command

                  $http_form_vars["ROSA_CMD"] = "PAN_NE";

}

 

ii)                   Edit the checkNavigation function to perform the pan
(around line 370)

 

i.e.        

case "PAN_NE":

            $oMapNavigator->pan( NORTH_EAST, 0.75 );

            return true;

            break;

 

Where NORTH_EAST is a constant (all other logical directions are also
supported) and 0.75 is the percentage of map width/height to move.

 

These changes can also be made directly to the application.php file.

 

 

HTH

Bill

Hello,

I am using maplab for my works and its very powerful and so good for my
liking. I have found out the the panning is only in the
north/east/south/west directions only. Is there a way of panning in any
direction( like the ones with the hand as icon) or if there is a way to pan
northwest/northeast/southwest/southeast.

I will really appreciate your help.
