Hello,
 
I created a toolbar button using a code similar to this (inside an app.trustedFunction):
 
app.addToolButton({
cName: "applyMetaData",
cLabel: "MetaData",
cEnable: "event.rc = (app.doc != null);",
cExec: "function_name();"});
 
So, after my pdf is open, The toolbar will display this button.
 
However, after that, I would like to control the enable/disable state of this button. Is this possible?
 
I tried to use a reference to the button variable, but I realized that despite being able to read the properties of the button (and actual, setting them), I cannot enable/disable the button.
 
Thank you.

The enabled state of a toolbar button is controlled entirely through the "cEnable" script, which is set when the button is created. You can't change the button after that so this script has to be setup exactly the way you want.

some questions.
1) What do you mean by "after my pdf is open, The toolbar will display this button"?

You defined a trusted function for button creation in a folder level Script. Are you calling the function from a document script, or is the button created when Acrobat is started.

2) What do you mean by "tried to use a reference to the button variable"?

As far as I know, no such animal exists in Acrobat JavaScript.

Hi,

The toolbar is created only after my document is open and not when acrobat is started. So, in the initialize event of my form I call a javascript folder function that will create the button.

After that I would like to control the state enable/disable of the button. For instance, if I click on a button in the pdf I woul like to disable the toolbar button.


"tried to use a reference to the button variable"?
-> just to say that I can read the properties of the button at any time, but not change them (well, it is just a global variable in the script).Thank you.
