Hi all,
a newbie question,
sorry for my english.
I'm testing a small application to understand the messages
memory management:
http://manual.qooxdoo.org/current/pages/development/memory_management.html
http://qooxdoo.org/docs/general/snippets#support_for_finding_potential_memory_leaks
"dispose method to use: Every" Missing destruct ... "line
In my config.json file I added the source-task disposerDebug.
"source-disposerDebug" :
{
"desc" : "source version with 'qx.disposerDebugLevel' for destruct support",
"extend" : [ "source" ],
"environment" :
{
"qx.disposerDebugLevel" : "1"
}
},
I launch the job "./generate.py source-disposerDebug"
I navigate to the URL of the source "http://myserver/myapp/source/index.html
"
and run the command "qx.core.ObjectRegistry.shutdown();"
in the javascript console of firefox ( firebug 1.12.6 )
The console only shows me a line with the total of items released:
>>> qx.core.ObjectRegistry.shutdown()
016957 qx.core.ObjectRegistry: Disposed 86 objects
I expected to see something like, one line for object that i forget to
dispose:
"Missing destruct definition for: __list"
"Missing destruct definition for: __stack
...
How I can see the log in more detail and find the objects that remain
release in the destructor ?
There are my javascript files:
Application.js
---------------
qx.Class.define("myapp.Application",
{
extend : qx.application.Standalone,
members :
{
__WindowManage : null,
main : function()
{
this.base(arguments);
if (qx.core.Environment.get("qx.debug"))
{
qx.log.appender.Native;
qx.log.appender.Console;
}
var button5 = new qx.ui.form.Button("ManageWindow create",
"myapp/test.png");
var button6 = new qx.ui.form.Button("ManageWindow destroy",
"myapp/test.png");
var doc = this.getRoot();
doc.add(button5, {left: 100, top: 130});
doc.add(button6, {left: 100, top: 160});
button5.addListener("execute", function(e) {
if ( this.__WindowManage == null ) {
this.__WindowManage = new myapp.ManageWindow();
}
this.__WindowManage.center();
this.__WindowManage.open();
this.warn("ManageWindow create it");
}, this);
button6.addListener("execute", function(e) {
if ( this.__WindowManage != null ) {
this.__WindowManage.destroy();
this.__WindowManage = null;
this.warn("ManageWindow destroy");
} else {
this.warn("button6 execute __WindowManage is null");
}
}, this);
// After execute button 6, execute "qx.core.ObjectRegistry.shutdown()" in
javascript console
}
}
});
ManageWindow.js
---------------
qx.Class.define("myapp.ManageWindow",
{
extend : qx.ui.window.Window,
construct : function()
{
this.warn("myapp.ManageWindow construct begin");
this.base(arguments, "Manage Window");
this.set(
{
modal : false,
showMinimize : false,
showMaximize : false,
allowMaximize : false
});
this.cdata = new qx.data.Array();
this.cdata.push( { "A1" : "a1" } );
this.cdata.push( { "A2" : "a2" } );
this.cdata.push( { "A3" : "a3" } );
this.cdata.push( { "A4" : "a4" } );
this.cdata.push( { "A5" : "a5" } );
// set the layout
var layout = new qx.ui.layout.VBox();
layout.setSeparator("separator-vertical");
this._setLayout(layout);
// Create the header of the list
var listHeader = new qx.ui.basic.Label(this.tr("Posts"));
listHeader.setPadding(5);
listHeader.setBackgroundColor("white");
listHeader.setAllowGrowX(true);
listHeader.setFont("bold");
this._add(listHeader);
// Create the stack for the list
this.__stack = new qx.ui.container.Stack();
this._add(this.__stack, {flex: 1});
// create list view
this.__list = new qx.ui.form.List();
this.__list.setDecorator(null);
this.__list.setSelectionMode("single");
this.__list.setPadding(0);
this.__list.setMargin(0);
this.__stack.add(this.__list);
this.warn("myapp.ManageWindow construct end");
},
members :
{
},
destruct : function()
{
// // // // // //
// // // // // // this._disposeObjects("__list", "__stack");
// // // // // //
}
});
