About KeyBindings

Hi, recently there were some discussion on implementing KeyBindings for our IDE.
There are at least 3 frameworks which address this functionality, the last one mentioned is the work done by Guillermo. I've implemented another one, for Gaucho. From what i understand, the previous work focuses on implementing GLOBAL keybindings . Basically adding behavior to HandMorph or PasteUpMorph or the toolbar ( docking bar) present in the World. My implementation is a generic keybinding for any Morph, which can be applied to any morph. Special cases for the docking bar or the paste up Morph can be easily implemented following this uniform scheme. I didn't have the time to integrate it into Pharo yet, but will do in one week from now. I like to bring up the discussion on which one we should adopt and integrate into Morphic, points in favor of my approach: 1) clean 2) customizable 3) generic: no special cases I believe the other Global keybindings should be a subset of this generic keybinding mechanism. Fernando pd: From a previous mail: "... So for example, if you want to delete any Morph from the system by pressing cmd-w, you have to add the following binding: condition := GMCondition compositeWith: #( #understandsKeyBindingCommandCondition #uneditedCondition ) ). binding := GMKeyBinding actingOn: $w asciiValue modifiedBy: #(#command) satisfying: condition applying: #close. m := Morph new. m addKeyBinding: binding . ... " pd2: Useful and related comment from Stef ".. A classVar Binding and an instance var binding. **All** the methods only access binding binding get initialized with the default table defined in Binding => we can have table binding sharing => we can have instance based customization. |

I want that. I would like to have morph specific table but with possible sharing I would like to have editor table (now defined as instance variables of the metaclasses) defined as ClassVar and instance Variables of the class so that we could share large table by default and have instance specific table if possible. pd2: Useful and related comment from Stef "..

Hello, very interesting work.
Can you provide some description? What is GMCondition? What is #compositeWith: , #modifiedWith:? Best regards, Denis 2011/1/31 Fernando Olivero <[hidden email]> Hi, recently there were some discussion on implementing KeyBindings for our IDE. |

Hi Fernando,
Sounds nice. I would be interested in having a bindings-per-morph solution.

I have the impression that Guillermo work is not the same as GlobalKeyBinding but I may be wrong
Anyway fernando could I have a look at your code? Because I really want that.

Stef: Yes! as soon as i'm finished with a paper (till next week) i
will work on integrating the functionality into the latest Pharo. And publish it as a slice perhaps? In Morphic-Keybindings ? Dennis: GMCondition (GauchoMorphic = GM ) are preconditions that must be satisfied for the key binding to be applied. In case they aren't satisfied, an rejected event is recorded, specifying the violated conditions. For example, you might want to restrict that a particular morph can only be closed ( cmd-w in the example above) if its selected (selected condition). I found it useful for customizing the Gaucho interface to a particular set of interaction rules.

Keymapping is very close to it, but is has a few differences:
- shortcuts are organized in categories - categories are attached to Morphs (to classes, not to instances) - every instance of the morphs who has attached the category, uses its shortcuts. Now I'm a little busy and stuck with Keymapping UI, but I expect to have something working in the near future too :).
