ExtJS:自动滚动垂直 FormPanels 添加到面板

Question

我正在编写一个应用程序，其中整个页面都有一个 BorderLayout。在南部，我有一个面板，我在其中添加了 FormPanel。我希望能够滚动该面板，以便可以滚动浏览 FormPanel。

到目前为止，我从搜索中找到的任何东西都没有帮助。我不太明白 ExtJS 在 LayoutManagers 的组合、设置大小和设置 AutoScroll 方面需要什么。

任何部分提示将不胜感激地跟进。

一段代码:

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();
}

你的南面板是你的组件的主要容器，所以它应该是 autoScroll:true您应该将表单和网格都添加到其中。您不能真正将网格直接添加到 FormPanel 中，因为它不是表单字段(您必须将其包装为字段或实现字段的某些接口(interface))。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 会是一个很好的布局)。
