ExtJS window dynamically add GridPanel items and show it - extjs

I want to show only one GridPanel,which I dynamically add by switch click button event, in window.
var event_menu = new Ext.menu.Menu( {
id : "event_menu",
items : [ {
text : 'record1',
handler : function() {
win.add(item_list_panel);//dynamica add GridPanel to show server data
win.doLayout();
item_list_store.load();
}
}, {
text : 'record2',
handler : function() {
win.remove(item_list_panel);//I want to remove it inorder to show the item_list_panel2 and only show one panel.
win.add(item_list_panel2);
win.doLayout();
item_list_store.load();
}
} ]
});
and this menu belong to my window tbar.
when I click record win will show item_list_panel and I want to when I click record2 the item_list_panel2 will show in win and item_list_panel will hide.
If I win.remove(item_list_panel) will have an error :
c.getPositionEl().dom is undefined
How can I do it,Thanks

I can barely understand your question, but if I understand correctly you can do it several ways.
you can destroy the component directly
item_list_panel.destroy()
you can go through your items and select it by id
win.items.item('item_id').destroy()
There are also ways to remove it without completely destroying it, depends what you want to do

Sencha Touch : dynamically update grouper function

I have a sencha touch 2.3 app that has a list which is grouped-
grouped: true,
The grouper function is defined in the store -
grouper: {
groupFn: function(record) {
return record.get('name');
}
}
All this works fine. Now, during runtime, I want to update the grouper function, eg: group it by some other record attribute like location
How do I do this dynamically?
I plan to update the grouper function when the user taps a button (eg: User wants to see the list of records grouped by location)
How to achieve this?
I believe you can use the setGrouper method provided by the Store class : http://docs.sencha.com/touch/2.3.2/#!/api/Ext.data.Store-method-setGrouper
You just need specify your gouper again :
yourStore.setGrouper({
groupFn : function(record) {
return record.get('location');
}
});
You may have to refresh your list manually, as I don't think there is an event that is fired by this change, and that is caught by the List to repaint.

Backbone - use different views or templates for same collection

The base model of my application has a status attribute.
Let's assume, for simplicity, that status might be either pending or deleted.
I have an upper menu with these two status values, when you click one of them you see all objects with this status (I use router to trigger a filter).
My problem is that I need to draw a different template for each status.
deleted object has delete forever and recover buttons
pending object has delete, edit and some other buttons (also some textarea...)
I wonder what would be the best solution for this problem.
I thought of creating a different view for each status, but then I don't know how to deal with it in the collection level.
I also thought of creating different templates and deal with it in the model-view level, but again - I have no idea whether it is possible and if yes - how.
Finally, I can solve it with same template and view, hiding what is not necessary inside the view, but then the code becomes quite ugly in my point of view.
Ideas?? Thanks!
If you want to create a different view for each status, you do it this way :
Router {
clickDeletedMenu : {
var collection = new MyCollection();
var deletedView = new DeletedView({ model : collection });
collection.fetch({ status : 'deleted' }); // filter deleted objects
},
clickPendingMenu : {
var collection = new MyCollection();
var pendingView = new PendingView({ model : collection });
collection.fetch({ status : 'pending' }); // filter deleted objects
},
}
If you want to create differents templates, you do it this way :
View {
render : {
if (this.model.status == 'deleted') {
// render deleted template
} else {
// render pending template
}
}
}
Finally, in my point of view, you can use the same template and view, and hiding what is not necessary inside the template not the view.
nb : the code is used just to illustrate the idea, it's not going to execute :)

Removing a fMath image properties dialog in ckeditor

I am a bit stuck with this so it would be great if you could help.
I am using Drupal 7 and Ckeditor 4.3. I am developing a site which has fmath equation editor integrated.
I have disabled the image button, as I don't want end users being able to upload their own images. On the other hand, users can use fMath to insert equations. The way fMath handles equation insertion is by inserting a img tag.
When users double click this image or when they right click over the image, they access the image properties dialog, where they can change source url of the image and few other things. On the url input text, they could change the source of the image so that they could insert their own images on the page, which is something I don't want.
The have been working with two different unsuccessful approaches until now trying to solve this problem:
Removing elements from the dialog, as the URL input text on the dialog (and the alt text as well).
Trying to disable the dialog itself.
I'd like to use a custom plugin to accomplish the desired behavior as I have different CKeditor profiles in Drupal.
I haven't been successful. Do you know how could I handle this undesirable behavior?
Ok, I ended up with something like this in the plugin.js file:
CKEDITOR.plugins.add( 'custom_doubleclick',
{
init: function( editor )
{
// First part, dialogDefinition allow us to remove the
// "Link" and "Advanced" tabs on the dialog
CKEDITOR.on( 'dialogDefinition', function( ev ) {
var dialogName = ev.data.name;
var dialogDefinition = ev.data.definition;
if ( dialogName == 'image' ) {
dialogDefinition.removeContents( 'Link' );
dialogDefinition.removeContents( 'advanced' );
}
});
// Second part, it disables the textUrl and txtAlt input text boxes
editor.on( 'dialogShow', function( ev ) {
var dialog = ev.data;
var dialogName = dialog.getName();
if ( dialogName == 'image' ) {
//var dialog = CKEDITOR.dialog.getCurrent();
// Get a reference to the Link Info tab.
console.log(dialog)
dialog.getContentElement( 'info','txtUrl' ).disable();
dialog.getContentElement( 'info','txtAlt' ).disable();
}
});
}
});
As you can see I didn't disable the dialog itself, but the non useful elements. I hope this can help to someone else.

Extjs checkbox selection issue

i am working in extjs4. i have grid with checkbox selection model. Grid is displaying files and folders. If folder get selected then i want to hide some menu. So have written code as-
selectionchange:function( model, selected, eOpts ){
var centralPanel = me.up();
var actionBtn = centralPanel.queryById('libraryactionBtn');
if(selected.length > 1) {
actionBtn.show();
//var i=0;
for(i=0;i<selected.length;i++)
{
if(selected[i].data.isLeaf)
{
centralPanel.queryById('library-action-menu-view').hide();
centralPanel.queryById('library-action-menu-viewOrAddTag').hide();
centralPanel.queryById('library-action-menu-viewOrAddNotes').hide();
centralPanel.queryById('library-action-menu-copyToCompaign').hide();
centralPanel.queryById('library-action-menu-copyToProject').hide();
centralPanel.queryById('library-action-menu-sendLink').hide();
centralPanel.queryById('library-action-menu-addtofavorite').hide();
centralPanel.queryById('library-action-menu-downloadItem').hide();
}
}
} else {
actionBtn.hide();
}
where selected.data.isLeaf is false for folder. Its executing correctly only first time. Next time when i am selecting file,then also its hiding menu for file. And if folder is deselected then also its hiding menu. So what modifications i need to do
first of all I don't see any code that shows the menu..You are just hiding the menu.
Secondly make sure selected[i].data.isLeaf is false and not "false".

Extjs 4.0.7, Editor Grid - how to get updated cell value?

I need to get(retrieve) updated cell value in controller. (MVC)
So I tried this,
var modified = this.getItemGrid().getStore().getUpdatedRecords();
console.log(modified); // return [] empty array
var modified = this.getItemList_Store().getUpdatedRecords();
console.log(modified); // return [] empty array
but always it returns empty array even I updated some cell value.
anybody know what I am doing wrong?
Here is my part of view code,
Ext.define("App.view.orders.ItemList_view", {
extend: "Ext.grid.Panel",
alias: "widget.itemList_view",
plugins: [
Ext.create('Ext.grid.plugin.CellEditing', {
clicksToEdit: 1
})
],
initComponent: function () {
this.store = "ItemList_store";
this.columns = [
{
xtype: 'checkcolumn', text: "Ship", width: 50, dataIndex: "DR"
},
{ header: "test", width: 100, dataIndex: "test",
editor: {
xtype : 'textfield'
}
}
];
this.selModel = Ext.create("Ext.selection.CheckboxModel");
//this.selModel = Ext.create("Ext.selection.CellModel"); // It does not works either.
this.callParent(arguments);
},
.
.
.
Thank you!
[EDIT]
Thank you very much for your answer! I have some more question about editor grid.
Its much different from Ext3. so I'm very confusing now :(
Q1. How to collect edited record data (once click button)?
the event fired once the grid cell be changed.
but I want collect edited grid record once I click the 'Update edited cell' button, and I want to update all together at the once.
In Ext3, I did like this,
(button) click : function(){
var modified = mygridStore.getModifiedRecords();
var recordsToSend = [];
Ext.each(modified, function(record){
recordsToSend.push(record.data);
});
var grid = Ext.getCmp('grid');
grid.el.mask('Updating','x-mask-loading');
grid.stopEditing();
recordsToSend = Ext.encode(recordsToSend);
Ext.Ajax.request({
url : '/test/test',
params : {
data : recordsToSend
},
success : function(response){
grid.el.unmask();
alert(response.responseText);
mygridStore.commitChanges();
},
failure : function(response){
mygridStore.rejectChanges();
}
});
}
How can I change the code for Extjs4 ?
Q2. I don't know still how to find out for changed checkcolumn.
I tried this, but I does not work for checkcolumn (of cause I tested after change checkbox)
// grid coumn
{
xtype: 'checkcolumn', header: "My Check Column", width: 50, dataIndex: "CH"
}
-
// in control
'myGrid': {
validateedit: function (plugin, edit) {
console.log(edit);
},
checkchange: function (plugin, edit) {
console.log(edit);
console.log(edit.value);
}
}
Q3. When I click the cell to edit, the show some HTML tag in -_-;;
I really appreciate for your help. and thank you very much for your valuable time!
The editors (cell editors or row editors) do not commit their values to the store until you complete the edit - which means pressing ENTER or blurring the active cell editor by clicking elsewhere on the page, or clicking the save button on the row editor form .
If your purpose for reading the updated value in your editor is to perform some kind of validation I would suggest simply listening to the validateedit event in your grid's controller, as described here.
The second argument that this event passes to your handler contains a lot of data about the edit that you can then perform validation with. If the edit doesn't pass your validation you can return false from your handler and the value in the celleditor will revert to it's original value. The validateedit event gets fired from the editor grid itself so you would add an event handler in your controller for it like this:
Ext.define('MyApp.controller.MyController', {
init: function() {
this.control({
'mygridpanel': {
validateedit: function(plugin, edit) {
// silly validation function
if (edit.value != 'A Valid Value') {
return false;
}
},
},
});
},
});
But you should check out the link above to see all the different objects available in that second argument I named edit.
The validateedit event is fired right before the record is committed into the store - after the user has already clicked ENTER or blurred the editor, i.e., while the editor is closing.
If you are trying to get the celleditor's value before it starts to close, for some reason other than validation for example, you could get the active celleditor's value like this:
// myGrid is a reference to your Ext.grid.Panel instance
if (myGrid.editingPlugin.editing) {
var value = myGrid.editingPlugin.getActiveEditor().field.value
console.log('value: ' + value);
}
If there is no active editor then myGrid.editingPlugin.getActiveEditor().field would throw an error, that's why I wrapped a conditional around it.
One other point I should make, for validation in editor grids, I found that it is easiest to just put a validator config in the grid column's editor definition. That will give you all the handy validation CSS while the user is setting the field's value and alert him if there is a problem with the value before he tries to save it.
To get an idea of what I mean, try entering letters in the date column of this example. Mouse over the editor cell and you will get the error message.
EDIT
It seems I misunderstood you original question, I'll break down my answers to your questions above though,
Question 1
Once you have completed an edit (clicked ENTER or ), your call to mygridStore.getModifiedRecords() should be working fine because the record will have been committed to the store. I see that it was not working, I will cover that in a moment.
I should point out that ExtJS4 has a store.sync() method as covered here.
Instead of extracting the modified records from the store, encoding them, manually doing an ajax request to save them to the server and then manually committing them you can call this sync method and it will take care of all of these actions for you.
If you have different URLs to handle the different create, read, update, destroy operations fired off by your store's load and sync methods, you can use the store's proxy api config to map your URLs to these operations as covered here. Or you can set-up your server side controller to be able to differentiate between your store's load request (read operations default to HTTP GET) and it's sync requests (create, update and delete operations default as HTTP POST).
There could be many different ways to go about doing this on the server side, the way I usually do it is to have one SQL stored procedure for GET requests and one for POST requests for any given store. I include the store name as an extra param and then my server side controller runs the appropriate stored procedure based on whether it is a GET or a POST request.
Question 2
Cell editing doesn't support checkcolumn edits. You have to make a different handler to listen to changes on that, something like this:
checkchange: function (column, rowIndex, checked) {
var record = store.getAt(rowIndex),
state = checked ? 'checked' : 'unchecked'
console.log('The record:');
console.log(record)
console.log('Column: ' + column.dataIndex);
console.log('was just ' + state)
}
Your call to mygridStore.getModifiedRecords() should be able to pick up the check changes also however, they get committed to the grid's store right away after being checked. store.sync() would also pick up changes to checkcolumn.
Question 3
I can't completely tell what is causing that problem but it may be something strange going on with your validateedit event, your handler should be returning true or false.
As I said earlier, I misunderstood the reason you originally asked this question. I thought you were trying to do some kind of validation while an edit was in progress. Now I understand that you are trying to get all of the modified records from the store after all the editing is completed in order to save them to the database, I was thrown off because in ExtJS 4 a store is usually saved to the database with the sync method as I mentioned.
In other words, you don't need the validateedit event or checkchange event to get a list of modified records.
The actual problem you are having might be trouble with the store's getter methods (getModifiedRecords, getUpdatedRecords) in some 4.07 versions, take a look at this post and this one.
So with all that said, the best advice I can give you is 1) try out the stores sync method for saving modified data to the database and 2) upgrade to ExtJS 4.1, there were a lot of bugs that were straightened out between 4.07 and 4.1 which you should be able to take advantage of, I cut out about 75% of the overrides I was using to make things work when I switched over to 4.1.
EditedGrid.plugins[0].completeEdit();
This will make the active changes commit and call edit event also.
listeners: {
validateedit: function (editor, e) {
//console.log(editor);
var oldVal = editor.originalValue;
var newVal = editor.value;
}
}
