Some usefull examples

[Rapotor]

Hello,

After a month of work with ExtJS, I would like to propose you a tutorial to help beginners. In fact, it's a summary of problems I had. All was resolved with very usefull docs and this forum but it take me a lot of time...
Then, I will maybe help some new ExtJS users (to sleep more the night :)) ) by this tutorial... I hope!

Thanks, much of what I just saw in your tutorial, I have figured out on my own. However, I would have been really glad to have these examples a few months ago and I am sure those new to Ext now will find them useful.

Yes, it was my goal! Some tricks are very simple to use but not always to find very fast. Every time win in research can be use to build any crazy new application \:D/

Hi !
Very good idead, indeed.
Actually this should be in a FAQ :)

My questions :

* For combo box, why do you use :
MyCombo.setValue(MyCombo.store.collect('id', true)[0]);
Instead of :
MyCombo.setValue(MyCombo.store.getAt(0).id);

It's incredibly slower (depending on the number of records).

* Also, for the grid, grid.selModel.selectFirstRow() is easier to read :)

* For the grid renderers, you should explain what is the 'params' argument for. Indeed, I spent much time before finding this one !

* Are you sure that window addons (shadow & co) aren't destroyed with the window itself ? And note that the default "closeAction" of a window is actually to close (and destroy) it.

Anyway, bravo, et very bonne initiative :p

MyCombo.setValue(MyCombo.store.collect('id', true)[0]);
Instead of :
MyCombo.setValue(MyCombo.store.getAt(0).id);

Yes, you right! The correct code is :
MyCombo.setValue(MyCombo.store.getAt(0).data.id);



* Are you sure that window addons (shadow & co) aren't destroyed with the window itself ? And note that the default "closeAction" of a window is actually to close (and destroy) it.

I have test 'closeAction' property but with no success.
Maybe, It was a fault from me... I will test this evening.

I will update my tutorial this evening. Thanks tof !
