Why Can't I Get My Window to "Show"?

    Below is a method that creates a very simple window. This method is used to create multiple windows. I use the argument "id" to distinguish between these windows.

    When the window is closed it is hidden rather than destroyed. When a user then wants to re-open the window this method should recognize the window has already been created and simply show it.

    The code appears to work correctly in that the it recognizes when a window already exists and it doesn't attempt to create it again. The problem is that when the line "winSelectView.show(this);" is executed the window does not actually get re-displayed.

    Any idea what the problem might be?

    Thanks,

    // Select DB View Window
    function selectView(id) {

    var winSelectView = Ext.get('select-view-'+id);
    if(!winSelectView){ // Reuse window on subsequent clicks
    winSelectView = new Ext.Window({
    width:400,
    height:300,
    closeAction:'hide',
    id: 'select-view-'+id,
    plain: true,
    title: 'Select a View',
    modal: true,
    shadow: false,
    items:
    new Ext.Panel({
    height : 200,
    items: [
    {
    html: 'Select the DB View '+id,
    }
    ]
    }),
    buttons: [{
    text: 'Save',
    handler: function(){

    winSelectView.hide();
    }
    },{
    text: 'Cancel',
    handler: function(){
    winSelectView.hide();
    }
    }]
    })
    }
    winSelectView.show(this);
    };


  • Thanks Condor, that worked great!

    What's the rule of thumb for using Ext.getCmp() as apposed to Ext.get()?

    Thanks,
    Matt


  • Use Ext.getCmp instead of Ext.get.


  • Please post meaningful titles and meaningful contents. It helps us to help you.


  • Elements are wrappers around DOM nodes.
    Components are composed of one or more elements, but are NOT elements themselves.

    If you want to get an Ext.Element use Ext.get.
    If you want to get an Ext.Component use Ext.getCmp.
