Ext 3 to 4 Migration

[freeranger]

I get that message all the time. It is annoying, but doesn't really seem to be an issue - certainly if you remove the compatability layer, you should not see any problems as a result of this deprecated shadow thing....

The Ext.data.Store getSortState() function appears to always return undefined. Is this the correct API to call to get the current sort state for a store, or is there a new function?

What replace gridPanel 'celldblclick' event ?
Currently I hacked around it by putting an editor in the cell and catching the 'beforeedit' event.

The use case: upon double-click, I open a sub-form with the record corresponding to the row, and set focus to the field corresponding to the column that the user clicked on.
The sub-form has more data than can be edited in the rowEditor.

Hi!

I've started migration my Ext3 application to Ext4.. It's a quite long job.

Regarding new way of doing configuration, I have an issue here.

In Ext3, I do something like: App.MyResultsPanel({query: 'the query'});

So in Ext4, it remains the same, except that in the class definition, I use the new way ("config:{query:null}}")..

One drawback in Ext3 that is stated in the docs is: you can overwrite any members of this class' instances during instantiation, including private methods and properties that should never be overwritten.

But I didn't notice that because "query" wasn't a private method in Ext3, but it is now in Ext4.

Continuing to read the docs, it says, for the New Way (Ext4): Configurations are completely encapsulated from other class members.
But for whatever reason, it is still overwriting the query() method, that prevent to scrollbar, and mousewheel to be display/work

Am I missing something obvious ?

Thanks

Hi,

I have started to migrate our codes from Ext 3 to 4. I find an issue with grid when using compatibility layer - grid headers are above the toolbar. It is really weird. Does anyone have the same issue? I guess it is a bug of compatibility files as it does not happen in pure Ext 4 environment.

Thanks.

Hi,

I had a menu in my application that contained several items, each with an icon on the left and text on the right. I noticed that the items that used iconCls to display the icon did not look good.

When I looked at the created HTML code with Firebug, I saw that the items using iconCls looked like this:

<img id="ext-gen1465" src="/images/ext/default/s.gif" class="x-menu-item-icon icon-mail"><span id="ext-gen1466" class="x-menu-item-text">Notifications...</span>

while the items that used "icon" looked like this:

<img id="ext-gen1469" src="/images/calendar.png" class="x-menu-item-icon "><span id="ext-gen1470" class="x-menu-item-text">Add year</span>

Looking further I saw that s.gif is not in the place it used to be: it now resides only in resources/themes/images/default/tree/s.gif
and also in the corresponding place in the "access" theme.

When I soft-linked it to the be in the images directory it all looked good.
Then I looked at the code in ext-all-debug.js and saw that BLANK_IMAGE_URL is now hard-coded , with IE6/7 pointed to get the image from sencha.com (why not have it locally for IE6/7, perhaps with a special name ?).
Removing the code that used to be in the page header fixed it:

Ext.BLANK_IMAGE_URL = '/images/s.gif';

I looked further at the code and saw that it was the same in Ext 3.3.3, and it's there since 3.0.0, but since it worked until Ext 4, I guess others will encounter this issue too.

I am unable to select text inside a grid.

Looking at the code I see that 'refresh' in 'Ext.view.Table' calls unselectable() for the table's element.

In ExtJS 3 I was able to make the text selectable using the work-around suggested here

Dear Ext team:

At the moment, there's an issue with the row body feature, that makes it impossible to upgrade my application to Ext4. I've posted it in the bugs forum, please have a look: 133565-4.0.0-error-when-combining-RowWrap-and-Grouping.

I'm also looking for a suitable way to hide grid columns by their ID (133562-Ext4-substitute-for-getColumnModel()).

Thanks for all the hard work!

Hi,

I'm trying to migrate a (big) desktop application (from ext3 to ext4) with an MVC architecture.
I want to ask to sencha dev team if there's an MVC version of ext4 desktop example planned.

Thanks for your developments!

I saw this mentioned previously in this thread with no solution and wondering if anyone else got this and fixed it:
[DEPRECATED][4.0][Ext.form.field.ComboBox] shadow (config): Use listConfig.shadow instead.

Someone mentioned that you get it when including languages, but I am not including any languages.
