Description:
The "On Update" selection combo box is not working to create or modify a foreign key constraint.

For instance, if you select "Cascade" on the "On Update" combo box editing a foreign key, and then press "Apply Changes", the changes is not taken into acount.

Tested against:
MySQL Server: 4.1.4-gamma-standard
MySQL Server: 4.0.13

How to repeat:
#1
A) Open MySQL Query Browser
B) Select a database schema with a table containing FK constraints
C) Edit a table with a FK constraint
D) Select tab "Foreign Keys" and click to select the FK constraint
E) Select another action to take "On Update": If the current action is "Cascade" select another action, like "Set Null"
F) Push button "Apply Changes"
G) There should be a message box saying "The changes you made did not result in the need to alter the table"

#2
A) Please do steps A to D above (Opening a schema, editing a table, etc).
B) Select another action to take "On Delete" instead of "On Update".
C) Push button "Apply Changes".
D) Please note that this time the message box warns about the changes to be made to the table. This is an "ALTER TABLE" statement including the needed ON DELETE change.
E) In the above statement, there is an ON UPDATE clause, but it's not the correct UP UPDATE action selected in the combo box.

Suggested fix:
The code must take into account the combo box selection.
