I'm looking for a way to handle the key in the Grid. I've closely followed the examples here: http://www.sencha.com/learn/architecting-your-app-in-ext-js-4-part-1 http://www.sencha.com/learn/architecting-your-app-in-ext-js-4-part-2
http://www.sencha.com/learn/the-mvc-application-architecture/So now everything works fine, but I'd like to handle keys in my Grid.
So I guess in the declaration "this.control({})
" I should just add another event concerning userlist
but it seems Grid don't have the "keypress" event.
Any idea how I should do (moreover how I should do with the new MVC pattern)?
Ext.define('GS.controller.Users', {
extend: 'Ext.app.Controller',
models: [
'User'
],
stores: [
'Users'
],
views: [
'user.List',
'user.Edit'
],
init: function () {
this.control({
/* (!) Actions in 'userlist' */
'userlist': {
selectionchange: this.userListSelectionChange,
itemdblclick: this.userEdit
},
'userlist button[action=create]': {
click: this.userCreate
},
'userlist button[action=delete]': {
cl开发者_Python百科ick: this.userDelete
},
/* (!) Actions in 'useredit' */
'useredit button[action=create]': {
click: this.userCreateValidate
},
'useredit button[action=save]': {
click: this.userEditValidate
}
});
},
userListSelectionChange: function(grid, selections, options) {
var panel = grid.view.up('panel'),
button = panel.down('button[action=delete]');
button.setDisabled(selections.length === 0);
},
userCreate: function(button) {
/* Using Ext.create() to pass variable create:true
* instead of the shortcut:
* var view = Ext.widget('useredit');
*/
var view = Ext.create('GS.view.user.Edit', {
create:true
});
},
userCreateValidate: function(button) {
var win = button.up('window'),
form = win.down('form'),
values = form.getValues();
this.getUsersStore().add(values);
this.getUsersStore().sync();
win.close();
},
userEdit: function(grid, record) {
var view = Ext.widget('useredit');
view.down('form').loadRecord(record);
},
userEditValidate: function (button) {
var win = button.up('window'),
form = win.down('form'),
record = form.getRecord(),
values = form.getValues();
record.set(values);
win.close();
this.getUsersStore().sync();
},
userDelete: function(button) {
var panel = button.up('panel'),
selection = panel.getSelectionModel().getSelection()[0];
if (selection) {
var store = this.getUsersStore();
store.remove(selection);
store.sync();
}
}
});
Define KeyMap(s) in your launch: function() {...}
right after you create the view.
