    Default Tip WebDesktop Icons

    In the Sencha Web Desktop uses the component dataview .. to create the icons ...
    More if the icons pass the area of visibility of User?
    Code:
    createDataView: function () {
            var me = this;
            return {
                xtype: 'dataview',
                overItemCls: 'x-view-over',
                trackOver: true,
                itemSelector: me.shortcutItemSelector,
                store: me.shortcuts,
                style: {
                    position: 'absolute'
                },
                x: 0, y: 0,
                tpl: new Ext.XTemplate(me.shortcutTpl)
            };
        },
    here enters the solution that will post!


    first component is no longer a dataview ...
    can be a panel, I'll opt by a component ...

    Code:
    {
      xtype: 'component',
      id: 'icon-desktop-view',
      style: {
         position: 'absolute'
      },
      x: 0, 
      y: 0
    }
    To improve the visibility I resolvie creates a separate file ..
    you can use a mixin to add the controller ...

    Code:
    Ext.define('ShSolutions.plugins.IconDesktop', {
    mixins: {
            observable: 'Ext.util.Observable'
        },
    
        x: 0,
        y: 0,
        btnPadding: 8,
        btnHeight: 78,
        btnWidth: 64,
        row: null,
        col: null,
    
    componentId: 'icon-desktop-view',
    
        tplIconMenuDeskotp: new Ext.Template([
            '<div class="ux-desktop-shortcut" id="{id}-shortcut">',
    '<div class="ux-desktop-shortcut-icon {iconCls}">',
    '<img src="',Ext.BLANK_IMAGE_URL,'" title="{name}">',
    '</div>',
    '<span class="ux-desktop-shortcut-text">{name}</span>',
    '</div>'
        ]),
    
        initColRow: function(){
    var me = this;
    me.col = {index: 1, x: me.btnPadding};
        me.row = {index: 1, y: me.btnPadding + me.y};
    },
    
    isOverflow: function(y){
    var me = this;
    if(y > (me.getViewHeight())){
    return true;
    }
    return false;
    },
    
    setXY: function(item, me, init){
    var bottom = me.row.y + me.btnHeight;
    var overflow = me.isOverflow(me.row.y + me.btnHeight);
    
    if(overflow && bottom > (me.btnHeight + me.btnPadding)){
    me.col = {
        index: me.col.index++,
        x: me.col.x + me.btnWidth + me.btnPadding
    };
    me.row = {
    index: 1,
    y: me.btnPadding + me.y
            };
        }
    
    if(init){
    if(init=='left'){var from = {x: -200,y: 100};}
    else if(init=='right'){var from = {x: 2000,y: 100};}
    else if(init=='bottom'){var from = {x: 1000,y: 2000};}
    else if(init=='top'){var from = {x: 1000,y: -200};}
    else {var from = {x: 0,y: 0};}
    
    item.animate({
    duration: 2000,
    from: from,
        to: {
            x: me.col.x,
            y: me.row.y
        }
    });
    }
    else{
    item.animate({
    duration: 1000,
        to: {
            opacity: 60,
            x: me.col.x,
            y: me.row.y
        }
    });
    }
    
    me.row.index++;
    me.row.y = me.row.y + me.btnHeight + me.btnPadding;
    },
    
        updateIconDesktopSize: function(){
    var me = this
    me.x = 0;
    me.y = 0;
    me.initColRow();
    
    Ext.each(Ext.getCmp(me.componentId).el.dom.childNodes, function(div){
    me.setXY(Ext.get(div.id), me);
    });
        },
    
        addIconDesktop: function(config){
    var me = this;
    var t = me.tplIconMenuDeskotp;
    t.compile();
    t.append(Ext.getCmp(componentId).el, {
    id: config.id, 
    name: config.name, 
    iconCls: config.iconCls
    });
    
    me.setXY(Ext.get(config.id+'-shortcut'), me, 'right');
    
    Ext.create('Ext.tip.ToolTip', {
        target: config.id+'-shortcut',
        html: config.tooltip
    });
    
    Ext.get(config.id+'-shortcut').on('dblclick', function(){
    me.getWindow(config.id, config.Controller, config.className);
    });
    
    new Ext.dd.DD(Ext.get(config.id+'-shortcut'), 'icon-dektop-move');
        },
    
        getViewHeight: function(){
    return (Ext.getBody().getHeight() - 35);
        },
    
    constructor: function (config) {
            this.mixins.observable.constructor.call(this, config);
        }
    
    });
    Mode Usage..
    Code:
    me.addIconDesktop({
      id: 'teste',
      name: 'Teste',
      iconCls: 'teste-shortcut'
    });
    after adding the icons you can use the resize method to adjust the icons after the thumbnailing ...
    Code:
    Ext.EventManager.onWindowResize(me.updateIconDesktopSize, this, {
    delay:500
    });
    Css...
    Code:
    .ux-wallpaper {background-color: #3d71b8;}
    .ux-wallpaper-tiled {background-repeat: repeat;}
    .ux-desktop-shortcut {cursor: pointer;position: absolute;text-align: center;padding: 8px;margin: 8px;width: 64px;}
    .ux-desktop-shortcut-icon {width: 48px;height: 48px;background-color: transparent;background-repeat: no-repeat;}
    .ux-desktop-shortcut-text {font: normal 10px tahoma,arial,verdana,sans-serif;text-decoration: none;padding-top: 5px;color: white;}
    .x-view-over .ux-desktop-shortcut-text {text-decoration: underline;}
    
    .teste-shortcut {
    background-image: url(../images/list48x48.png);
    }
    .x-ie6 .teste-shortcut {
    background-image: none;
    filter:progid:DXImageTransform.Microsoft.AlphaImageLoader(src='images/list48x48.png', sizingMethod='scale');
    }

    I'm thinking lot of people wouldn't have any idea what you are talking about so an example somewhere would probably help.
