<FONT FACE="Verdana, Helvetica, Arial"><SPAN DEFANGED_STYLE='font-size:12.0px'>I just committed the cvs and my website <a href="http://www.public.asu.edu/~cmbarton/files/grass_gismgr"><http://www.public.asu.edu/~cmbarton/files/grass_gismgr></a> a series of bug fixes and updates for the GRASS GIS Manager.<BR>
<BR>
IMPORTANT NOTE: After posting to the developer list and soliciting comments, discussing with Markus, and with Bernhard, I moved all the gui files to a new directory in the source tree. d.m and gis.m are no longer in the /display directory. They are moved to a new /gui/tcltk directory. Other GUIs can use this directory. For example, if a Qt GUI is developed, it can go into /gui/qt. GUIs don’t really belong with d.* modules. The new directory will make it easier to manage the GRASS GUI. <BR>
<BR>
Currently, dm and gm remain in $GISBASE/etc in the binary distribution. <BR>
<BR>
<BR>
The bug fixes include:<BR>
<BR>
canvas screen resizing did not match window resizing<BR>
shrinking command console window made buttons disappear<BR>
(Thanks to Glynn Clements for helping clear up these mysteries)<BR>
<BR>
auto name issue for RGB/HIS panel<BR>
<BR>
zooming not preserving resolution exactly (Thanks for Maciek Sleczka for suggesting how to fix this)<BR>
<BR>
<BR>
Updates include:<BR>
<BR>
modifying zooming again. Zooming now stays on until you press the right mouse button. This matches the other display controls. However, I agree with Glynn that this does not follow interface guidelines exactly (the right button for Windows and Mac, at least, is reserved for contextual menus). But I don’t have a better solution for how to stop the the action of these tools for the moment. Double clicking is often used by graphic programs, but I worry that a misplaced double click will change a zoom or pan. I could use a key-click combination, but don’t know which, if any, are considered standard for stopping tool actions (Anyone have some real information on this?). A potentially good idea is to make the buttons work like radio buttons and add a pointer button. GIMP works this way. However, if possible, this would take some creative programming and time to do it. I’ll keep it in mind. If anyone wants to tackle it....<BR>
<BR>
If you don’t want to draw a rectangle to zoom, simply clicking the mouse when in zoom/unzoom mode will zoom/unzoom by 20%. I did note that doing this excessively and rapidly (i.e., not waiting for the screen to redraw) can cause the active map display to lock up.<BR>
<BR>
You’ll notice a new ‘NVIZ’ button on the map display tool bar. Clicking this will open NVIZ and display any raster and vector files in the associated layer tree. The 2.5D maps don’t display in the map display window yet, but at least you can display the same maps in NVIZ that you are displaying in the map display.<BR>
<BR>
For rasters, the ‘base map’ will be used as elevation map and ‘drape map’ will be used as color. If there is no ‘drape map’ defined, the base map will be used as color. Multiple rasters will produce multiple surfaces in NVIZ. <BR>
<BR>
For vectors, if the vector contains any points, it will be displayed in NVIZ as a points. Otherwise it will be displayed as vector lines/boundaries. <BR>
<BR>
Enjoy,<BR>
