beforeresize

[joehebe]

I want to do something before the size of panel changing.
But Panel don't support the event of beforesize.
Please give me some suggestions.
Thank you!

I can only think to extend the Panel and add ur function before the resize event

[joehebe]

I try to addEvent({'beforeresize',true});
But I don't know where to fireEvent('beforeresize');

Not sure how you will override the resize event.

What do you want to do before the resize - do you want to stop/ disallow the resize?

There may be a way to accomplish your desired end result without a before resize event.

Thank you!

I don't want to stop/ disallow the event of resize.

when the panel resize, I want to get the size of panel before the panel changing

Not sure this will work / help but - if you have a variable that gets the size of the panel on load using myPanel.getSize() (i.e. origSize = myPanel.getSize()) then after the resize event - that would still have the original size (i.e. origSize.width and origSize.height).

You could process as needed and once done, set origSize to the new panel size for the next resize event to have the old value.

heh? isn't the resize event already provide u with the panel size before it's resized?

resize : ( Ext.Component this, Number adjWidth, Number adjHeight, Number rawWidth, Number rawHeight )                                     Fires after the component is resized.                              Fires after the component is resized.             Listeners will be called with the following arguments:         this : Ext.ComponentadjWidth : NumberThe box-adjusted width that was setadjHeight : NumberThe box-adjusted height that was setrawWidth : NumberThe width that was originally specifiedrawHeight : NumberThe height that was originally specified

so if my understanding is correct u can do:

yourpanel.on('resize',function(panel,newwidth,newheight,oldwidth,oldheight){
  //wat to do with oldwidth and oldheight ?
});
