clear_coords

<static> void clear_coords()

function to be called on mouse exit events.

Must be defined and set (via setHandler) elsewhere in the application, or nothing happens with these events.

main.setHandler(DBOX_MOUSEEXIT, clear_coords);	

/**

do_query

<static> void do_query()

function to be called at query time.

Must be defined and set (via setHandler) elsewhere in the application, or nothing happens at query time.

A setup to display query results in a new window might be:
(note the "ms" variable below is a Mapserv object instance, and "function" is intentionally mispelled to avoid confusing our documentation generator)

/**

main_area

<static> void main_area(a, d, l, n)

function to be called on area events.

Must be defined and set (via setHandler) elsewhere in the application, or nothing happens with these events.

typically this is where you would do something with the coordinate information generated by dBox. For example, you might convert from pixels to map coordinates and update a page element. You can also do simple feature digitizing using this feature

main.setHandler(DBOX_AREA, main_area);

/**

main_measure

<static> void main_measure(s, t, n, a)

function to be called on measure events.

Must be defined and set (via setHandler) elsewhere in the application, or nothing happens with these events.

typically this is where you would do something with the coordinate information generated by dBox. For example, you might convert from pixels to map coordinates and update a page element.

main.setHandler(DBOX_MEASURE, main_measure);

/**

main_mousemove

<static> void main_mousemove(x, y)

function to be called on mouse move events.

Must be defined and set (via setHandler) elsewhere in the application, or nothing happens with these events.

main.setHandler(DBOX_MOUSEMOVE, main_mousemove);

/**

main_setbox

<static> void main_setbox(minx, miny, maxx, maxy)

function to be called on mouse click/box draw events.

Must be defined and set (via setHandler) elsewhere in the application, or nothing happens with these events.

typically this is where you would trigger draw or query behaviour within your application.

main.setHandler(DBOX_SETBOX, main_setbox);

/**

map_draw

<static> void map_draw()

function to be called at map draw time.

Must be defined and set (via setHandler) elsewhere in the application, or nothing happens at draw time.

A minimal setup, handling nothing but the map draw, might be:
(note the "ms" variable below is a Mapserv object instance, and "function" is intentionally mispelled to avoid confusing our documentation generator)
