Is there way that delete perspective from 'open perspective' dialog at Runtime

I want to remove perspective from 'Open 开发者_JAVA百科Perspective' dialog at Runtime.

Please give me advice.

You can use activities to hide a perspective from the dialog. You can also use http://wiki.eclipse.org/Product_Customization to remove the offending definition from the plugin.xml before it is loaded (Product customization depends on Equinox Transforms).

See How remove pop-up menu contributions in eclipse RCP for references to both methods.
