Disable Buttons
- Thread starter MDoom
- Start date
Hi MDoom,
The trick we use, is to add
PROCEDURE ButtonSet
** enable/disable buttons before READ statement
SHOW GET m.TheButton DISABLE
RETURN .T.
And then change the READ statement to
READ <other params> WHEN ButtonSet()
This way, the buttons are enabled/disabled just before the READ cycle kicks in.
Hope this helped,
Jan Schenkel.

Do you have a SHOW GETS ENABLED somewhere? This will toggle your Initially Disabled setting at runtime.
Let me add to jschenke's post.
If you have a command button set, i.e., more than 1 button for a variable, you can toggle the status of the individual buttons by using:
SHOW GET abc, 1 disabled
SHOW GET abc, 2 disabled
SHOW GET abc, 3 enabled
This will disable the first two buttons, and leave the third enabled. Also, if a single button is disable via the:
'\\' picture clause, like \\Quit, it can later be overridden with the SHOW GET abc ENABLED also.

There is a SHOW GETS ENABLE in the REFRESH procedure but removing that messes with operation of the other buttons.
I've tried adding 'SHOW GET ... DISABLE' statements in the setup code snippet without success.
Also, if I create a ButtonSet Procedure, where or which code snippet do you access the READ statement?
thanks

SHOW GETS ENABLE enables ALL gets.
After the SHOW GETS ENABLE statement in the refresh snippet, put in the code to disable your button(s) you want disabled. The setup snippet happens before the refresh snippet so it won't work there.
Or, you can put the buttonset call in the refresh snippet.
