[maplab-users] dropdown list and direct value entry

[Jeff McKenna]

Hi Peter,

This issue has been dealt with in the development version
(http://www2.dmsolutions.ca/webtools/maplab/maplab_dl.html).  This is what is
listed in the mapfile reference for the SIZE property of the LABEL object:

> SIZE [integer]|[tiny|small|medium|large|giant]

> Text size. Use "integer" to give the size in pixels of your TrueType font based
> label, or any of the other 5 listed keywords to bitmap fonts.

Our interface uses [integer] for the textbox, and
[tiny|small|medium|large|giant] for the drop-down list.  So we've rearranged the
LABEL object's interface in MapEdit so that the following is displayed for the
SIZE property:

Font size:[textbox](integer)   Or   Bitmap size:[dropdown]

We've also added javascript so that when a user selects from the dropdown and
applies the changes the textbox value is removed.  If a user then enters a value
in the textbox the dropdown value is removed.  Keep in mind that the textbox is
for truetype fonts and the dropdown-list is for Bitmap fonts.

I hope these changes make some sense to you and everyone else.
