ExtJs 4 Formpanel progress bar (wait mask) gray mask not properly hidden bugs

First you must know the exception two methods Ext.MessageBox.hide () and Ext.MessageBox.updateProgress (value, "Progresstext", "MSG") (three parameters, see name to know meaning),
Note the number between value 0-1, which indicates the progress of the progress bar.
First: (Control progress by the size of the progress, full progress is 1)

Code

The code is as follows	Copy Code
function Read4 () { var progressbar=ext.msg.show ({ Title: "Caption", Msg: "Control progress by the size of the progress", Progress:true, width:300 }); var count=0; var bartext= ""; var curnum=0; Ext.TaskMgr.start ({ Run:function () { count++; if (count>=10) { Progressbar.hide (); } CURNUM=COUNT/10; bartext=curnum*100+ "%"; Progressbar.updateprogress (Curnum,bartext); }, interval:1000 }) }

Second: (through fixed-time control of progress loading)

Code

Code

The code is as follows	Copy Code
function Read5 () { var progressbar=ext.msg.show ({ Title: "Caption", Msg: "Complete Progress by fixed time", WIDTH:300, Wait:true, Waitconfig:{interval:500,duration:5000,fn:function () { Ext.Msg.hide (); }}, Closable:true }); settimeout (function () { Ext.Msg.hide (); },5000); }

Dynamic Update progress Information

It looks good up there. But in the example application I found that waiting for the progress bar (wait mask) gray mask can not hide the bug, I modified the example below

The code is as follows

Copy Code

Ext.define (' Ext.form.SubmitFix ', { Override: ' Ext.zindexmanager ', Register:function (comp) { var me = this, Compafterhide = Comp.afterhide; if (Comp.zindexmanager) { Comp.zIndexManager.unregister (comp); } Comp.zindexmanager = Me; Me.list[comp.id] = comp; Me.zIndexStack.push (comp); Hook into Component ' s afterhide processing Comp.afterhide = function () { Compafterhide.apply (comp, arguments); Me.oncomponenthide (comp); }; }, /** * Unregisters a {@link ext.component} from this zindexmanager. This should is not * need to be called. Components are automatically unregistered upon destruction. * The {@link #register}. * @param {ext.component} comp the Component to unregister. */ Unregister:function (comp) { var me = this, list = Me.list; Delete Comp.zindexmanager; if (list && list[comp.id]) { Delete List[comp.id]; Relinquish control of Component ' s afterhide processing Delete comp.afterhide; Ext.Array.remove (Me.zindexstack, comp); Destruction requires that the topmost visible floater to be activated. Same as hiding. Me._activatelast (); } } });

The bug is fixed in version 4.1.2, and the way to fix it in advance is to add the following patch code to the project:
