Question

我正在编写一个应用程序，我的整个页面都有BorderLayout。在南部我有一个Panel，我添加了FormPanels。我希望能够滚动该面板，以便我可以滚动FormPanels。

到目前为止，我从搜索中找到的任何内容都没有帮助。我不太了解ExtJS在LayoutManagers的组合方面需要什么，设置大小和设置AutoScroll。

任何部分提示都将非常感激。

代码段：

new Ext.Viewport({
    layout: "border",
    items: [{
        region: "north",
        contentEl: "title",
        height: 50
    }, {
        region: "center",
        id: "mappanel",
        title: "Map",
        xtype: "gx_mappanel",
        map: map,
        layers: [layer],
        extent: extent,
        split: true,
        tbar: toolbarItems
    }, {
        region: "east",
        title: "Details",
        width: 300,
        split: true,
        id: "east-panel",
        laout: 'fit'
    }, {
     region: "south",
     id: "south-panel",
     height: 200
    }, {
     region: "west",
     id: "west-panel",
     width: 300
    }]
});

matchedTrailJunctionsPanel = new Ext.Panel({
        title: "Matched Trail Junctions2",
        id: "matched-trail-junctions",
        autoScroll:true
        //layout: 'anchor'
    });

var southPanel = Ext.getCmp('south-panel');

southPanel.add(matchedTrailJunctionsPanel);
southPanel.doLayout();

createTrailJunctionPanel = function(trailJunction) {
var trailJunctionPanel = new Ext.form.FormPanel({
    labelWidth: 75,
    width: 350,
    defaultType: 'textfield',
    items: [{
            fieldLabel: 'Junction Name',
            name: 'junction-name'
        }],
    autoScroll:true,
    //anchor: '100% 100%',
    height: 100
});
matchedTrailJunctionsPanel.add(trailJunctionPanel);
if(trailJunction.publicTrailSegments.length == 0) {
    matchedTrailJunctionsPanel.add(new Ext.form.Label({text: 'No public trails matched'}));    
} else {
    var grid = new Ext.grid.GridPanel({
        store: mapMatchObjectStore,
        columns: [
            {id:'publicTrailSegment',header: 'Trail', width: 160, sortable: true, dataIndex: 'publicTrailSegment'}
        ],
        stripeRows: true,
        autoExpandColumn: 'publicTrailSegment',
        height: 350,
        width: 600,
        title: 'Matched Trail Junctions'       
    });
    matchedTrailJunctionsPanel.add(grid);
}
matchedTrailJunctionsPanel.doLayout();
}

Answer 1

您的南面板是您的组件的主要容器，因此它应该是autoScroll:true，您应该将表单和网格添加到其中。您无法直接将网格添加到FormPanel中，因为它不是表单字段（您必须将其包装为Field或实现Field的某些界面）。它可能适用于没有布局的南方（浏览器应该直接在表单之后粘贴网格）但通常最好指定适当的布局（在这种情况下vbox将是一个好的布局。）

Answer 2

包含面板必须设置高度。包含的面板必须设置高度或设置autoHeight: true。
