Editor toolbar action visibility [message #493141]

Hi all,

I have an editor action that I would like to be visible on the toolbar
only when my editor is active. I am using the old-fashioned
org.eclipse.ui.actionSets extension point. I used JDT's toggle
Breakcrumb action as my template, as that behaves in the way that I
desire. This has retarget="true", and no class defined. The editor then
registers a global action handler for this action. Unfortunatly, my
action always seems to be visible, even it is disabled when my editor is
not active. I can't see what I am doing differently. Can anyone help?

Here is how I have declared my action:

<extension point="org.eclipse.ui.actionSets">

<actionSet
id="com.xyz.ui"
label="XYZ Actions"
visible="false">

<action
id="com.xyz.ui.toggleGridAction"
label="Toggle Grid"
style="toggle"
tooltip="Toggle Grid"

toolbarPath=" org.eclipse.ui.edit.text.actionSet.presentation/Presentation "
retarget="true">
</action>

</actionSet>

</extension>

P.S. If anyone can show me how to do this using the org.eclipse.ui.menus
extension point, I am open to that also.

If you are interested in commands, use visibleWhen with activePart
expression

Prakash is correct, it's better to use org.eclipse.ui.menus/org.eclipse.ui.commands (and possibly org.eclipse.ui.handlers) unless you already have a legacy actionSet you need to work with.

The actionSet you posted is correct (and should be disabled when your editor is not available). To make it visible depending on if your editors is active, you use actionSetPartAssociation with the actionSet.
