Re: [qooxdoo-devel] Problem with class inheritance

Hi Roman,

thank you for the explanation, now it works fine. The 5px height wasjust for testing. But it is a strange error Message for missingLayouts i think.

Thank you for your help.

Hi Tom

I copied your code to test it locally.
Your container is lacking a valid layout.
This line:
var container = new qx.ui.container.Composite(box);

Should be something like:

var container = new qx.ui.container.Composite(newqx.ui.layout.HBox());


However, the result is rather strange, because you set your textfields

to a height of 5 pixels which make them unusable. I would recommendyou

don't alter the height of them.

Since you're using a HBox Layout for the window and one for the
composite, you could skip the composite entirely. The resulting code
could look like this:

-- snip --

addContent : function()
{
   var windowLayout = new qx.ui.layout.VBox(10);
   this.setLayout(windowLayout);
   this.setMinWidth(300);
   var loginField = new qx.ui.form.TextField("Enter Login").set({width
: 260});

var passField = new qx.ui.form.TextField("EnterPassw").set({width :

260});
   this.add(loginField);
   this.add(passField);

}

-- snap --

Regarding the re-build: You'll have to rebuild when you're adding new

classes. Just changing code (without new includes) won't require arebuild.

Hi Roman,

no, i thought that i just have to do this once and for source andonce

for build to ditribute it. I tried it know with "generate source" and
with "generate source-all" but this gives the same result.

Hi Tom

At first sight, your code seems to be fine.
Did you re-build your source using generate.py ?

Cheers - Roman

Hi,

i created a class, which is inherited from a form.Window. The class
definition is defined that way:

*/
qx.Class.define("firstapp.ui.LoginBox",
{
extend : qx.ui.window.Window,



/*

*****************************************************************************
   MEMBERS

*****************************************************************************
*/
construct : function(name,icon)
{
  this.base(arguments,name,icon);
  this.set
  ({
      modal         : true,
      showMinimize  : false,
      showMaximize  : false,
      allowMaximize : false
  });



  this.addContent();
},



members :
{
  /**

* This method contains the initial application code and getscalled

   * during startup of the application
   */
   addContent : function()
   {
      var windowLayout = new qx.ui.layout.VBox(10);
      this.setLayout(windowLayout);
      this.setMinWidth(300);
      var container = new qx.ui.container.Composite(box);
      container.setPadding(20);
      var loginField = new qx.ui.form.TextField("Enter Login").set(
{height : 5, width : 260});
      var passField = new qx.ui.form.TextField("Enter Passw").set(
{height : 5, width : 260});
      container.add(loginField);
      container.add(passField);
      this.add(container);
   }
}
});

Now in the Main funtion i try to instantiate the class like this :

*/
    var loginWindow = new firstapp.ui.LoginBox("LoginWindow",null);

Every time i start the application i get an Error like :Undefined value

in this line. Does anybody know what is wrong here ?

Thank you
Tom
