我想把一些按钮放在桌面上，而不是我的代码，来自我在国外的朋友。我试图把它放在这个代码的每个地方，但它不是那里的按钮。
这个桌面视图的代码很多，请帮我理解放在哪里。

如果我在这里插入按钮它会像整个桌面一样大。我不需要这么大的按钮。
me.windows = new Ext.util.MixedCollection();
me.contextMenu = new Ext.menu.Menu(me.createDesktopMenu());
me.items = [
// { xtype: "wallpaper", id: me.id+"_wallpaper" },
{
xtype: "TESTdataprovidersdataview",
xtype: 'button',
text: 'Help'
}];
me.items = [
{
xtype: 'button',
width: 111,
height:111,
text: 'Show Toolbar',
action: 'showToolbar'
},
{
xtype: "TESTdataprovidersdataview"
}];
答案 0 :(得分：1)
经过几个小时的处理，我意识到它有多么简单。
我需要实现的所有内容：
me.items = [
{
xtype: 'button',
text: 'Show Toolbar',
maxWidth: 95,
maxHeight: 32,
margin: '5%, 800%',
itemId: 'niceButton',
align: "right",
action: 'showToolbar',
pack: 'center',
listeners: {
mouseout: function() {
if (!this.mouseout) {
this.mousedOver = true;
alert('Would you like to show Toolbar');
}
}
}
},
{
xtype: "TESTdataprovidersdataview"
}];
