Hi,
I want to add a key binding to my customized IAction class.
for eg: Suppose i want to invoke my action on pressing "ALT+1"
heres the code i wrote but its not working.
This code has a class NewKey which extends action and another class which
instantiates this action and adds it to the text editor.
public class NewKey extends Action{
String code="";
public NewKey(String name,String c){
super(name);
code=c;
}
public void addConfig(int keycode){
super.setAccelerator(keycode);
}
public void run(){
try{
System.out.println("RUN Key activated");
PrintWriter pr= new PrintWriter(new
FileOutputStream("c:\\acbk.txt"));
pr.println("RUN Key activated");
}catch(Exception e){
e.printStackTrace();
}
}
and this code instantiates this class
IWorkbench wb = PlatformUI.getWorkbench();
ICommandManager icm= wb.getCommandSupport().getCommandManager();
KeySequence keyseq=KeySequence.getInstance("ALt+1");
String com=icm.getPerfectMatch(keyseq);
NewKey nk=new NewKey("TrialAction","TrialActionSuccessFul");
if(com==null){
System.out.println("Registering..");
nk.addConfig(SWT.ALT|'1');
nk.setActionDefinitionId("TrialAction");
nk.setDescription("TrialAction");
nk.setId("TrialAction");
nk.setEnabled(true);
System.out.println("Registered..");
}else
MessageDialog.openInformation(shell,"HOT KEY","Match is: "+com+"
Already Exist");
IEditorPart editor= window.getActivePage().getActiveEditor();
((ITextEditor)editor).setAction("TryAction",(IAction)nk);
This should ideally register the action to the keybinding but its not
happeneing. I tried checking if at all the action is registered and i
found it is.heres the code
if(((ITextEditor)editor).getAction("TryAction")!=null){
MessageDialog.openInformation(shell,"HOT KEY","IAction is not null");
MessageDialog.openInformation(shell,"HOT KEY","Accelerator : "+
((ITextEditor)editor).getAction("TryAction").getAccelerator());
}
The Message box shows Accelerator as 65585 which is correct (ALT+1 =
(1<<16)+49) but whne i press ALT+1 nothin happens.
HELP!

Did you read the javadoc for IAction.setAccelerator()?
" This method should no longer be used for actions in the Eclipse workbench.
IWorkbenchCommandSupport and IWorkbenchContextSupport provide all the
functionality required for key bindings. If you set an accelerator using
this method, then it will not work in the workbench if it conflicts any
existing key binding, or if there is a different key binding defined for
this action's definition id. The definition id should be used instead --
referring to the command in the workbench from which the key binding should
be retrieved. "
All your questions can be answered by rtfm.

Use the org.eclipse.ui.contexts to define a context for your commands.
Use the org.eclipse.ui.commands extension to define your command category
and commands.
Use the org.eclipse.ui.bindings extension to bind keys to the command- make
sure to set the commandId and the contextId.
Create your action and set its action definition id to the command id. If
you are defining it in the plugin.xml, make sure to set the definitionId.
In your editor, override initializeKeyBindingScopes() and call
setKeyBindingScopes with your contextId.
Then the action will fire when you press the key combination when your
editor is the active part.

Yes, it is more complicated. But, unfortunately, this is what happens when
you've got different accelerator schemes (and other fun stuff).
<org.eclipse.ui.commands>
<command
id="commandId"
name="Name"
description="Description"
categoryId="categoryId" />
<!-- Use an existing category, if possible. If not, then you have
to define the category as well.
-->
<category id="categoryId" name="Name" description="Description" />
</org.eclipse.ui.commands>
<org.eclipse.ui.bindings>
<key
sequence="CTRL+E"
commandId="commandId"
schemeId="org.eclipse.ui.defaultAcceleratorConfiguration" />
<!-- If you are developing for MacOS X as well, then M1+E may be
more appropriate. Please read the schema documentation for
the sequence attribute.
-->
</org.eclipse.ui.bindings>

Hi,
I already implemented this method. The problem with thgis method is that
all the entries need to be made to the plugin.xml.
I want to create key bindings programmatically i.e it will be decided at
runtime which keys associate with what action.
so basically i dont have any static information on commands and key
bindings, everything is dynamic, thats why i wanted to use some way to
attach keys programmatically.
Please tell me if u have a way

Have you investigated if it can be done programatically using
IBindingService.savePreferences(), KeyBinding and KeySequence?
You can create a KeySequence, assign it to a KeyBinding. KeyBinding can then
be assigned to a ParametrizedCommand which can be
created from a Command.
Then IBindingService can be used to save the preferences.
See how the KeysPreferencePage does it.

Hi Sunil,
Thanks for your suggestion. I can't figure out how the last part of your
proposal will work. I can define a KeyBinding and I can define a
ParameterizedCommand with a Command, I can use the IBindingService to get
bindings for my ParameterizedCommand. But as far as I can tell there is
no programmatic way of introducing my new key binding into the
IBindingService. Am I missing something?

IBinding[] bindings = IBindingService.getBindings();
Find your binding. Replace it in the array.
IBindingService.savePreferences(IBindingService.getActiveSch eme(),bindings);
That may do it.
