Re: [udig-devel] How to reset map bounds and viewport bounds?

[Jesse Eichar <jeichar@xxxxxxxxxxxxxxx>]

Hi,

On more recent versions of uDig (starting RC10 I think) this issue is fixed.  Until you upgrade you will have to do a nasty reflection hack and reset the 

boundsESet

and

bounds

fields.

Something like the following code should do it:

Field bounds = map.getClass().getDeclaredField("bounds");

bounds.setAccessible(true);

bounds.set( map, null );

Field boundsESet = map.getClass().getDeclaredField("boundsESet");

boundsESet.setAccessible(true);

boundsESet.set( map, false );

Then trigger a refresh and you *should* be good.

I haven't actually tried it but it should work.  Otherwise move forward to RC11 and try with that version.

Hi,

I found if I change GeoResource,the udig map can't display correct map.I know the reason: the map property is not right,because I have change the GeoResource,but the map property still record the old bounds? and I found when udig exit, udig will create a *.umap file to record some information of map?
why udig can't reset the map or viewport bounds?
how can I reset its?

Thanks !
